# Changelog

All notable changes to the neoschool class are documented in this file.

## [1.3.26] - 2026-10-23

### Added
- `mathlettersoptions`: fontspec options for the letters set by `mathletters`.

### Fixed
- A title or section heading containing `\mathbb`, `\mathcal`, `\mathbf`,
  `\mathrm` or a math accent such as `\vec` no longer makes the compilation
  loop or stop; the PDF title and bookmarks keep the plain letter.

## [1.3.25] - 2026-10-21

### Changed
- Inspired profiles: `\part` follows each house (AMS run-in bold line,
  *Physical Review* and ACM aligned left, Springer centred, Mir and IEEE
  centred with a spaced or small-capital label) instead of the generic part.
- `ieeelike`: the abstract dash is spaced in French and German, attached in
  English.

## [1.3.24] - 2026-10-20

### Added
- Profiles `amslike`, `mirlike`, `physlike` and `springerlike`, inspired by AMS
  articles, Mir books, *Physical Review* and Springer textbooks, each with a
  TeX Live fallback font.
  `amslike` uses New Computer Modern Book (`mlmodern` under pdfLaTeX), with
  Latin Modern as fallback.
- Two-column profiles `ieeelike` and `acmlike` (`onecolumn` keeps one column).
- Title layouts `amslike`, `mirlike`, `physlike`, `springerlike`,
  `springerrule`, `ieeelike` and `acmlike`.
- `sectionnumstyle=period` and `para`; `sectiontextstyle=smallcaps` and `caps`.
- `mathletters` (LuaLaTeX): letters and digits of formulas in the text font or
  in a given font.
- Fallback font lists in `mainface`, `sansface`, `monoface` and `mathface`.
- `fullwidth` environment for full-width content in two-column documents.
- Warnings for font options that are not font commands, for `scshape`
  headings in a font without small capitals, and for a main or sans font
  without bold.
- Family, weight and shape per element, inherited from `headfamily`,
  `headweight` and `headshape`: `section…`, `thm…`, `ex…` and `ad…`.

### Changed
- `headstyle`, `titlestyle` and `headfootstyle` are renamed `headfamily`,
  `titlefamily` and `headfootfamily`; the old names raise an error.
- Admonitions: the titles of `soft`, `modern`, `classic` and `professional`
  follow `headweight` instead of a hard-coded bold.

### Fixed
- `\setmathfont` ranges set by the user were erased at `\begin{document}`;
  `mathfacescale` is now applied when the math font is first loaded.
- `adstyle=soft` with `adboxopacity=0`: no inner margins, so the text lines up
  with the body text.
- Decimal opacities (for example `exframeopacity=40.5`) no longer stop the
  compilation.
- `mirlike` under XeLaTeX: monospaced text at its normal size.

## [1.3.23] - 2026-10-10

### Changed
- `flow`: the four lines follow one wave shape with shifted phases, so they
  cross evenly and meet at both ends; solid colours and tints replace the
  transparency.

## [1.3.22] - 2026-10-07

### Changed
- `bubbles`: the bubbles use the three palette colours with more presence
  (a third anchor disc, higher opacity, boosted on `darktheme`); the subject
  label is set like in the other layouts.
- `blocks`: a bar of seven solid blocks in the palette colours and tints
  replaces the overlapping translucent rectangles.
- `stream`: a bold spine with two full-colour companions, two faint rules and
  a leading dot replaces the scattered segments.
- `cloud`: a more even draw of the discs (uniform spread, capped opacity, no
  dark knot above the title), boosted on `darktheme`.
- `exam`, `evalgrade`, `evaliconsgrade`: the grade strip labels use the sans
  label font like the rest of the header.
- `\competencies`: the four faces are flat discs in the palette colours instead
  of the glossy tikzsymbols faces; readable with `print`, `unicolor` and
  `darktheme`.
- `pseudocode`: the title separator follows `codeseparator` like `code`.
- `twocoltoc`: the entries use the same fonts, colours and leaders as the
  normal table of contents.

### Fixed
- Admonitions with a hidden frame (`soft`) kept the invisible frame width, so
  they sat 0.6 to 1.2 mm further from their neighbours than the theorem boxes.
- Code boxes had about 2 pt more padding below the last line than above the
  first.
- Exercises with a run-in title (`capsule`, `inline`, `line`, `rule`...): the
  space after one and the space before the next added up, so two consecutive
  exercises, or an exercise next to a box, were about 2 mm further apart than
  an exercise next to text.
- A `\usepackage{unicode-math}` in a document (pandoc templates add one) broke
  the compilation under LuaLaTeX and XeLaTeX when `mathface` was not set; it is
  now ignored with a warning, since the math fonts come from `mathface`.

## [1.3.21] - 2026-10-06

### Added
- Option `codelang` (on with `profile=coder`, off with `nocodelang`): the
  language name at the top right of each code block, in the title bar when
  there is one, hidden when the first line leaves no room.

### Fixed
- `exstyle=item`, listed in the manuals, was not accepted by the class.
- `amssymb` and `amsthm` can be loaded after the class (they conflicted with
  `newpxmath`, and `amssymb` with `unicode-math`); the AMS symbols `\digamma`,
  `\beth`, `\Finv`... were missing under LuaLaTeX.
- German documents use `ngerman` (post-1996 orthography and hyphenation)
  instead of the 1901 variant babel warned about.
- An unknown `codestyle` value raises a warning and uses `shadow` instead of
  stopping at the first listing.
- `\neoheader` keys `leftcontentfill` and `rightcontentfill`, documented
  but without effect: `true` now draws the icon box with inverted colours.
- A `_` in a listing title (`[Fonction solutions_possibles]`) no longer stops
  the compilation.
- The `inline`, `shell` and `raw` exercise styles no longer trigger the
  KOMA-Script warning about `\@startsection`.
- `\texttt` in the title of a code box or `neobox` was invisible (same colour
  as the bar) or boxed with `inlinecodebox`: it now follows the title colour.
- Theorem-like environments and admonitions accept a bare title in brackets
  (`\begin{definition}[Title]`, as with `amsthm`), a bare `tcolorbox` key
  (`[breakable]`) and an `=` inside a `title=` value (`$f(x) = g(x)$`).
- `\part` in `twocolumn` documents spilled over the second column.
- `solstyle=lines`: the two rules of every solution were 1 em too wide.
- An unescaped `_` in `\texttt` (`\texttt{donnees_2026.csv}`) no longer stops
  the compilation.
- `apmep` no longer loads `fancyhdr`, whose `\chead`/`\cfoot` replaced those of
  `scrlayer-scrpage`: the class footers (page number, author) vanished and
  KOMA-Script warned. `\lhead`, `\rhead`, `\lfoot`, `\rfoot`, `\fancyhf`,
  `\headrulewidth`, `\footrulewidth` and the `fancy` page style are provided
  on top of `scrlayer-scrpage`; a `\usepackage{fancyhdr}` is skipped.
- `mockexam`: the page count on the cover was one too many when the document
  ended with `\newpage`.
- The PDF metadata (title, author, subject, language) were empty; a `\\` in the
  title becomes a space there.
- `inlinecodebox` kept the theme colours under `print` and `unicolor`.
- An unknown `thmstyle` value raises one warning and uses `tag`, instead of
  nine warnings and `block`.
- The identical-copy modes `2a5toa4`, `2a4toa3` and `4a5toa3` executed the
  auxiliary writes once per copy (table of contents doubled, labels multiply
  defined, duplicate PDF destinations): under LuaLaTeX the copies now skip
  them; under pdflatex and xelatex the class warns.
- The A5 output modes applied the A4 type area to A5 paper (two typearea
  warnings); the fallback type area follows the paper size and the dead
  `\headheight`/`\footskip` settings are gone.
- Every message is a class message (`Class neoschool Warning` or `Error`).
- `darktheme` no longer overrides a `globalcolor` or `headfootcolor` given
  explicitly.
- The title layouts `memphis`, `confetti`, `particles`, `cloud` and `wave`
  scale with the paper width instead of assuming A4; `bristol` sets its
  subtitle in `subtitleColor` instead of a fixed gray.
- Dead code removed: `headsepline` settings inside page styles, an unused key
  set, `fancyhdr` remnants, duplicate package loads in `apmep`; the exam
  strings (institution, name, class, duration, date, mark, comments) come
  from the language tables.
- Manuals: `code*`; the admonition layout option applies to `minimal`,
  `modern` and `soft`; the identical-copy modes need LuaLaTeX.
- Manuals: `fancyhdr` is incompatible with the class (`scrlayer-scrpage`); the
  theorem constructors `\new<style>theorem` are documented; nothing may
  follow `\begin{exercise}[...]` on the same line; a last section lists the
  habits to drop when coming from `article`.

## [1.3.20] - 2026-10-05

### Fixed
- `titlealign=left` raised "Environment neo@titleflushleft undefined";
  `titlealign` now also applies to the default title layout.
- A `code` environment or `\verb` inside an admonition (`tip`, `warning`,
  `method`, ...) no longer fails. A `lstlisting` written with `^^J` line
  ends as a workaround must be rewritten as a plain listing.
- `noback`, `thmnoback` and `clean` left the theorem backgrounds in place.
- A nested theorem-like box without title inherited the title, label and
  options of its parent.
- User environments defined with `\NewEnviron` lost `\BODY`.
- `mathastext` with lualatex: misspelled `eulergreek` option; with lualatex
  and xelatex, `\square` and `\blacksquare` were undefined (`\unchecked`,
  `\done`, `\wontfix`).
- An option given explicitly now overrides the profile, as documented.
- `print`: table of contents, `\mc`, code comments, line numbers and
  `\NoAILogo` are now black. `darktheme`: `\mc` is readable.
- pdflatex: a title longer than 85 bytes could be cut inside an accented
  letter ("Invalid UTF-8 byte sequence"); it is cut between two words.
- `mathfaceoptions` was ignored with lualatex and xelatex.
- `\textwithimage` overflowed under `parskip=half`.
- `vspacing`: the spacing around exercises ignored its 0.85 coefficient as
  soon as the factor differed from 1, so a factor of 0.9 gave more space
  than 1.
- `icon=\faLaptop` on an exercise raised a `fontawesome5` error: the `icon`
  property of exercises and the `icon` key of admonitions accept an icon
  name or a command.
- pdflatex: digits, operator names and delimiters of formulas were set in
  Computer Modern (`newpxmath` was loaded before the text font).
- xelatex: the default fonts fell back to Latin Modern instead of TeX Gyre
  Pagella, Heros and Cursor.
- `noback`, `exnoback` and `clean` left the exercise backgrounds in place
  when a profile or `exboxopacity` set one.
- `\bm` did not embolden with `mathface` or with xelatex.
- `apmep`: `\ei` and `\ein` lost the imaginary unit.
- `semibold` with `monoface`: typographic quotes in code.
- `darktheme`: unreadable colors with `unicolor`, in the table of contents
  (parts, `monotoc`), with `sectionstyle=highlighted` and in the `bristol`,
  `bauhaus`, `memphis`, `magazine` and `banner` title layouts.
- French table of contents with `\part`: every number was followed by a gap
  as wide as "Première partie".
- `\codeinline` lost braces (f-strings, dictionaries) and backslashes, and
  failed on `%`.
- Listing numbers: a titled `\codeinput` did not step the counter and an
  untitled `code` consumed a number.
- pdflatex: accented letters stopped the compilation in the `html`, `json`,
  `bash`, `csv`, `yaml`, `markdown` and `assembly` listings, and so did
  characters such as `→ ≤ … ’ — ² ×` in any listing.
- pdflatex: straight quotes in `code`, `\verb`, `\codeinline` and `\texttt`
  were printed as typographic quotes.
- Pseudo-code keywords were French in every language: they are English by
  default, with a German translation.
- The class no longer creates the unused counters `thm`, `def`, `prop`,
  `lem`, `cor`, which clashed with user counters of the same name.
- `solstyle=box`: the boxed solution ignored `noback`, `clean`, `exnoframe`
  and `exterminator`.
- `darktheme`: black text in boxed solutions, `pseudocode` and `mathraster`,
  and low-contrast `\mrk`.
- `\gridfill` right after a paragraph sent the grid to the next page.
- `\customgrid`: lines overshot the frame when a size was not a multiple of
  the step.
- xelatex: `mathfacescale` was ignored and formulas were smaller than with
  lualatex.
- `\withqrcode` changed the size of the QR codes that followed.
- Long titles ran off the page in the boxed-title styles (`tile`, `curve`,
  `sticker`, `pastel`, `card`, admonition style `material`): they now wrap.
- `exstyle=separator`: overfull line at every exercise under `parskip=half`
  and long subtitles not wrapped; `exstyle=rule`: the grade was split when
  the title filled the line.
- German: "points" was not translated in five exercise title layouts.
- `minted`: inline code ignored `print` and `darktheme`; it is typeset
  without highlighting in these two modes.
- German `\AILogo` reads "KI".
- The warnings for an unknown `profile` or `titledecor` were printed
  without spaces.
- Long titles also wrap in the `titlebox`, `tighttitle` and `memphis`
  title layouts, and long subtitles in `band`.
- `mockexam` and `shortexam` print « ÉPREUVE D'INFORMATIQUE » (elision,
  capitals) and hide the line when no subject is given.
- `\begin{code}{c++}`, `{javascript}` and any language known to
  `listings` (`php`, `sh`, ...) are accepted; `%` no longer starts a
  comment in `markdown` listings.
- The `badge`, `digit` and `counter` exercise styles (and their `-outline`
  variants) failed with a frame opacity below 60, as with `profile=zen`.
- `adstyle=material`: the title was invisible with a frame opacity below 60.
- `thmstyle=tile` ignored `boxarc` and `thmboxarc`.
- `exstyle=line`: 6.7 pt too much space after each exercise.
- `titlecolor` was ignored by `bristol`, `bauhaus` and `memphis`; the
  `brush` drawing overlapped a tall title block.
- Titles and subtitles too long for the fixed-height headers (`eval`,
  `evalicons`, `evalgrade`, `evaliconsgrade`, `bauhaus`, `magazine`) are
  scaled down instead of overlapping the rest of the header.
- `titlealign` shifted the text below the title in the layouts that do not
  align the title; the decorative headers no longer reset the PGF random
  seed of the document.
- `particles`: the bubbles are placed from the page corner; they moved
  with the margins and only covered the right half of the page.
- `banner` and `confetti` only printed the date when an author was given,
  and left a dangling bullet with an author and an empty date.
- `onlytitle`: a second `\maketitle` in the same document printed nothing.
- Manuals: `\inlinebox` takes `[background][text][frame]`; `adborder`
  only acts on the `classic` and `minimal` admonition styles; layouts
  ignoring `titlealign`, `titlesize`, `titlestyle`, `titleweight` or
  `titlecolor` are listed.

### Changed
- Python listings use the Python 3 keyword set of `listings`: `None`,
  `True`, `False`, `with`, `as`, `yield`, `lambda`, `assert`, `raise`... are
  coloured as keywords.
- Unknown class options, and unknown values of `titlelayout`, `titlealign`,
  `sectionstyle`, `sectionnumstyle`, `sectiontextstyle`, `sectionalign`,
  `headerules`, `solstyle`, `adstyle`, `exstyle` and the box shapes, raise
  a class warning (`adstyle` and `exstyle` no longer stop the compilation).
- `conjecture` has its own color (`conjectureColor`) instead of the color
  of `remark`.
- `\notebook`, `\nbminorgrid` and `\nbmajorgrid` follow the paper size and
  `print`.
- `print` now disables `darktheme`; an unknown `titlesize` raises a warning.
- xelatex with `mathface`: `unicode-math` is loaded without the ISO styles,
  as with lualatex.
- Default `\neoheader` values depend on the language: unchanged in French,
  neutral in English and German.
- Internal helper macros carry the `neo@` prefix (`\oldcenter`,
  `\titlespacing`, `\applytextstyle`, `\mynewtcbtheorem`, `\examfield`,
  ...); documented commands are unchanged.
- `summary` and `activity` show the clipboard list and the puzzle piece
  announced by the manuals, instead of the bars and the pen; the manuals
  show the task list actually used by `method`.
- The `todonotes` margin and `tocbasic` number width warnings are filtered;
  `\CheckCommand` is restored once `microtype` is loaded.

## [1.3.19] - 2026-10-03

### Added
- New `fillable` boolean option (disabled by default): the answer areas
  `\lines`, `\answerfield`, `\answerframe`, `\emptybox` and `\vardots`
  (hence also the name line of the exam headers) become PDF form fields
  that can be filled in on screen, and `\unchecked` items become check
  boxes. The fields are laid over the printed areas without taking any
  room: the page layout is the same with and without the option, with
  lualatex, pdflatex and xelatex, and the document still prints like the
  paper version; the only difference is that a `\lines` area is no longer
  split across pages.

## [1.3.18] - 2026-09-27

### Fixed
- Under the `apmep` option, `\pg`, `\pp` and `\ps` were silently undefined
  with lualatex and pdflatex: `siunitx`, loaded by the class, declares the
  unit abbreviations `\pg` (picogram) and `\ps` (picosecond) at the start of
  the document, before the `\providecommand` of the option. They are now
  defined unconditionally. The `\providecommand` of `\i` and `\d` never had
  any effect either (kernel accents) and were removed; use `\Ci`, `\dd` and
  `\dx`. A duplicate definition of `\cg` (curve of g, never active) was
  removed, and `\cf`, `\dr` and `\deprim` no longer add a space after the
  symbol. The option also loads `diagbox` and `scratch3`, required by the
  DNB subjects.
- With the `beside label` key of `code` and `\codeinput`, the frame of the
  box touched the first character of each line (no left padding). The box
  now keeps half of the normal horizontal padding on each side, so the text
  width, and therefore the line breaking, is exactly the same as before; the
  `bar` style keeps its own padding.
- `\frenchgrid` had no vertical space before and after, unlike `\grid` and
  `\customgrid`, and the starred (centred) form left the following
  paragraphs centred. Both commands now also end the current paragraph
  first: placed right after a sentence, their space used to fall after the
  grid instead of before it.

### Changed
- In light mode, headers, footers and the muted texts and rules of the title
  layouts now use a neutral grey derived from the text colour
  (`textColor!75!backgroundColor`), as dark mode already did, instead of the
  structural colour of the theme. The difference is barely visible with the
  grey structural colours of the catalogue and keeps the furniture sober with
  the amber of `twilight`. The `headfootcolor` option still overrides it.

### Added
- Three themes. `twilight` brings back the palette of the 1.1.x theme of
  the same name (navy titles, slate subsections and theorems, teal
  exercises, amber inline code and subsubsections), whose amber and teal
  were darkened to reach the WCAG AA contrast ratio of 4.5:1 on white and
  on the tinted background of boxes; documents that still request
  `theme=twilight` get it back instead of the `axiom` fallback.
  `pomegranate` (bright red, slate and teal) and `wisteria` (violet,
  orange and green) are two lighter, more saturated palettes than the rest
  of the catalogue, checked against the same contrast rule.

## [1.3.17] - 2026-09-20

### Fixed
- Four theme colours did not reach the WCAG AA contrast ratio of 4.5:1 on the
  tinted background of boxed environments: the tertiary colour of `excellence`
  (2.73:1), `terra` (3.84:1) and `rhodium` (4.16:1), and the secondary colour of
  `cyprus` (4.45:1). All four were darkened, hue and chroma unchanged, and now
  sit above 4.5:1 on white, on the tinted background and in dark mode.
- In the default colour mode (and with `darktheme`), the hyperref colours
  `neo@filecolor` and `neo@citecolor` were only defined by the `print` and
  `unicolor` options: any link to a local file (`\href{/posts/page/}{text}`,
  as produced by Pandoc), any `run:` link and any citation failed with
  "Undefined color". File links now take the URL colour and citations the
  internal link colour.

### Added
- Three themes fill the gaps of the catalogue: `olive` (olive and brick),
  `atoll` (turquoise, coral and violet) and `sienna` (terracotta, blue and
  green). None of them uses a teal tertiary colour, unlike the 22 themes that
  already colour their exercises in teal.

### Changed
- The list of themes in the manuals is now grouped by colour family, in the
  same nine families as the online playground, instead of a single
  alphabetical list.
- The project home page moved from https://apps.edulatex.xyz to
  https://edulatex.xyz (class header, README, manuals).

## [1.3.16] - 2026-09-19

### Fixed
- The full-width layout commands `\gradingstrip`, `\withqrcode`,
  `\splitcontent` and `\lines` overflowed the right margin by 1em under the
  default `parskip=half`, whose `\parfillskip` requires the last line of a
  paragraph to leave 1em free: they now end their own paragraph with a zero
  `\parfillskip`. A full-width table of your own still needs `parskip=half-`
  (documented).
- `\splitcontent` inserted a 2.7pt space between its two columns (unprotected
  line end after the gap).
- `\withqrcode` emitted two "varwidth: Failed to reprocess entire contents"
  warnings on every use (the specials of the QR picture inside a tabularray
  cell); the picture is now boxed. The command also inserted a spurious
  paragraph skip before the block (`\noindent\par`): the block now sits half
  a line higher.
- In the `tile` theorem and exercise styles, the tab outline did not join the
  box frame cleanly: it was drawn in the full theme colour while the frame is
  mixed by `thmframeopacity`/`exframeopacity`, its curve reached the top rule
  at an angle with a vertical offset only valid for a 0.8pt border, and its
  fill differed slightly from the box background (faint triangle under the
  tab). The outline now takes the frame colour, lands tangentially on the axis
  of the rule whatever the border width, and the tab is filled with the box
  background colour.

## [1.3.15] - 2026-09-14

### Fixed
- Under LuaLaTeX the default monospace font (Latin Modern Mono) was loaded
  without bold faces, so `\bfseries` had no effect in code listings:
  keywords were distinguished by colour only, and not at all in `print`
  mode. The bold and bold-italic faces (`lmmonolt10`) are now loaded; the
  XeLaTeX fallback gets them too.
- The monospace font no longer inherits the TeX ligatures: straight quotes,
  backticks and double hyphens are typeset verbatim in listings, `\verb`
  and `\texttt` instead of typographic quotes and dashes.
- `\codeinline` without a language argument typeset the code in the text
  font; it now uses the monospace font, like `\codeinline[text]`.
- The `html` code style failed with "tag undefined" unless another listings
  language had been loaded before, and never highlighted tags or
  attributes: the language now declares the `html` aspect and no longer
  intercepts `<` and `>` before the tag parser.
- The `code` and `codenonum` environments and the `\codeinput` commands no
  longer emit spurious space tokens before the box (unprotected line ends
  in their `code` option).
- Under LuaLaTeX, digits and operator names (`\cos`, `\log`) in formulas were
  typeset in Latin Modern instead of the text font: `newpxmath` fixes the
  `operators` family on the roman font in force when it is loaded, before
  the main font is selected. The family is now re-declared on the main font.
- The `exam` title layout gives more room to its right column
  (`X[4,l]X[1,c]X[4,r]`), so that a long class name such as "Première tronc
  commun" no longer wraps.

### Added
- `unbreakable` exercise property (`\begin{exercise}[unbreakable]`): the
  exercise is never split across pages and moves to the next page as a
  whole when it does not fit, whatever the `exstyle`; a printed solution
  stays with its exercise.
- `beside label` key for code boxes (`\codeinput...[beside label]`, `code`
  environment): the first code line sits on the line of the preceding label,
  for code given as a QCM proposition (`\choice`) or as a list item; the
  box is then unbreakable.

### Changed
- `\texttt` no longer applies language hyphenation patterns to inline code
  (no more "getEle-mentById") and no longer breaks after a hyphen; line
  breaks remain possible after an underscore, a slash or an opening
  parenthesis, and before a dot followed by a letter. The new `tthyphenation` option restores the former
  behaviour for narrow layouts where long identifiers would otherwise
  overflow the line.

## [1.3.14] - 2026-09-13

### Fixed
- The `notion` title layout (also used by the `material` profile) could not
  be compiled: a spacing length was never defined and a TikZ path lacked its
  closing semicolon.
- The `centeredcode` option raised a pgfkeys error ("I do not know the key
  '/tcb/center,'").
- `sectionstyle=shadedline` failed with centred section titles (the default
  alignment) because of an invalid TikZ coordinate expression.
- `nofrenchlist` and `frenchlistaspar` no longer fail when the `french`
  option is not loaded; they are simply ignored.
- With the `minted` backend, the `assembly` and `csv` code styles are now
  mapped to the `nasm` and `text` Pygments lexers instead of failing.
- With the `listings` backend (the default), the `js` code style could not
  be loaded: it requested a `JavaScript` language that `listings` does not
  provide and carried a stray `style` key without a value. The class now
  ships its own `javascript` language definition.
- Added the missing `css` language and code style to the `listings`
  backend (`\begin{code}{css}`), which `minted` already supported.
- A plain `lstlisting` environment with line numbers no longer fails with
  "Undefined control sequence": the default listing style referred to a
  line-number spacing macro that was never defined. The `code` and
  `codenonum` environments were not affected.

### Removed
- The undocumented and unused `exseparator` class option.

## [1.3.13] - 2026-09-05

### Fixed
- The `solution` heading no longer shows a double space between the
  solution name and the "of exercise" text ("Solution  of exercise 1"),
  in every language and with every solution template. The localized
  names carry their trailing space themselves; the templates added a
  redundant `~` (or an end-of-line space) on top of it.

## [1.3.12] - 2026-08-20

### Fixed
- `\codeinline` no longer inserts a spurious space after the inline code.

## [1.3.11] - 2026-08-18

### Fixed
- Code blocks are no longer darkened when backgrounds are disabled
  (`codenoback` or the global `noback`) while frames remain enabled; the
  behaviour now matches the theorem boxes.
- With both `codenoframe` and `codenoback`, the `shadow` and `bar` code
  styles no longer show a residual shadow behind the block. All other
  option combinations are unchanged.
- Fixed a compilation error ("Undefined control sequence") when loading
  the class with the `minted` option. Line-number spacing is now resolved
  consistently across the `listings` and `minted` backends.
- `\sbseries` and `\textsb` now fall back to bold under LuaLaTeX and
  XeLaTeX when the `semibold` option is disabled or the font provides no
  SemiBold face, as already documented.
- The `semibold` option no longer overrides the
  `mainfacescale`/`sansfacescale`/`monofacescale` scale factors.
- The `titlecolor`, `headcolor`, `subcolor` and `subsubcolor` class
  options now take effect.

### Documentation
- The three manuals (English, French, German) and the HTML pages have been
  brought in line with the class: obsolete options removed, default values
  corrected, and the theme list completed (59 themes).

## [1.3.10] - 2026-07-05

### Added
- New `semibold` boolean option (disabled by default) to enable automatic
  detection of the SemiBold variant of `mainface`/`sansface`/`monoface`.
  Recommended only when the chosen font actually ships a SemiBold weight
  (Inter, Source Sans, IBM Plex, Lato, etc.).

### Changed
- Automatic SemiBold detection is now opt-in via the new `semibold` option
  (was always active before). This removes the luaotfload "Reload initiated"
  message that appeared on fonts without a SemiBold variant (TeX Gyre,
  Latin Modern, etc.). When disabled, `\sbseries` falls back to `\bfseries`.

### Fixed
- Italic shape is no longer rendered smaller than the upright text under
  XeLaTeX and LuaLaTeX. The global `Scale=MatchLowercase` feature was
  previously applied to the roman family, causing each font shape
  (regular, italic, bold) to be rescaled independently against the
  reference x-height; with fonts whose italic x-height differs from the
  regular (such as TeX Gyre Pagella), the italic ended up visibly smaller.
  The roman family is now declared with `Scale=1`, while sans-serif and
  monospace families keep `Scale=MatchLowercase` to remain visually
  aligned on the roman x-height. The undocumented `scale` option,
  previously dead code, has been removed.

## [1.3.9] - 2026-05-25

### Changed
- Unified vertical-spacing logic: the `vspacing` factor now scales every
  global skip uniformly (`\parskip`, `\abovedisplayskip`, `\belowdisplayskip`,
  `\floatsep`, `\textfloatsep`, `\intextsep`, `topsep`, `itemsep`) regardless
  of its value. The arbitrary threshold at `0.76` has been removed; the
  document contracts smoothly down to any `vspacing` value.

### Added
- New `listparskip` boolean option, **enabled by default**, propagating the
  `parskip` spacing inside lists (`itemize`, `enumerate`, `description`) for
  consistent paragraph rhythm between text and lists.
- Complementary `nolistparskip` option to opt out of the above (keeps lists
  compact regardless of `parskip`).

### Fixed
- `partopsep` is now forced to `0pt`, so the vertical space before a list
  no longer depends on whether the source has a blank line above it.

## [1.3.8] - 2026-05-23

Intermediate release introducing the initial `listparskip` option (off by
default at this stage). Superseded by 1.3.9, which makes the option active
by default and unifies the spacing model.

## [1.3.7] - 2026-05-15

### Added
- New class option `parskip` accepting standard KOMA-Script values
  (`false`, `half`, `full`, `half-`, `half*`, …). Replaces the previously
  hard-coded `parskip=half` setting and removes the need to load the
  `parskip` package alongside the class.

## [1.3.6] - 2026-05-01

### Added
- New `nofrenchmath` option to opt out of the automatic loading of the
  `frenchmath` package with the `french` language option.

### Changed
- With the `french` language option, the `frenchmath` package is now loaded
  automatically (French conventions in math mode). `ncccomma` is skipped in
  that case to avoid a conflict, `\vide` and `\Ker` are cleared before
  loading, and the redundant warnings emitted by `frenchmath` about
  `\mathscr`, `\leqslant`/`\geqslant` and `\varnothing` are silenced.

### Fixed
- The running-footer title is now computed once at the beginning of the
  document and cached, and the title is detokenized before being measured.
  Titles longer than 85 characters that contain macros are no longer
  truncated blindly (which could cut a macro in half): the class keeps the
  full title and emits a warning suggesting `\shorttitle`. Plain overlong
  titles are still truncated at 85 characters with an ellipsis.

## [1.3.5] - 2026-04-11

### Added
- Table of contents: `part` entries are now styled (large colored entry
  without dotted leader) and followed by a thin colored rule, both in the
  default rendering and with `compacttoc`; page breaks immediately after a
  part entry are prevented.

### Changed
- The `math` package bundle is now loaded by default; new `nomath` option
  to disable it for documents that do not need advanced mathematical
  typesetting (reduces compilation time).
- `\euro` is now provided globally by the `eurosym` package (with the
  `gen` option) instead of being defined only under the `apmep` option.

### Fixed
- `\part` headings: the number, decorative rule and title are wrapped in a
  minipage so the heading block can no longer be split across pages; the
  space above part headings is normalized (`beforeskip=5em`).
- The `toolbox` admonition color now follows the structural color of the
  theme, like `note`, `reminder` and `summary`.

## [1.3.4] - 2026-03-29

Maintenance release: copyright years updated to 2025-2026 in the class
header; no functional change.

## [1.3.3] - 2026-03-21

### Added
- New `rubis` theme (navy primary with a vivid red secondary).
- New `html` listings language and code style, highlighting tags,
  attributes, strings and comments.
- New `text` code style: plain listing without any syntax highlighting.

### Changed
- The `assembly` code style no longer relies on the `[x86]Assembler`
  dialect: it now highlights a case-insensitive mnemonic set covering x86,
  ARM and LMC (data transfer, arithmetic, logic, jumps and branches,
  stack, I/O), with registers and assembler directives emphasized
  separately and string support.
- Widow and club penalties raised from 9999 to 10000: lone lines at the
  top or bottom of a page are now strictly forbidden.

## [1.3.2] - 2026-03-14

### Changed
- The `mockexam` cover page now prints the subject name in uppercase.
- `\mrk` margin marks are now typeset in sans-serif using the structural
  color.

### Fixed
- A document without `\title` no longer sends the footer-title measurement
  into an infinite loop: an empty title is now predefined.
- Invalid dimension expression (`0.5*\baselineskip`) in the spacing applied
  to code blocks when both `codenoframe` and `codenoback` are set.

## [1.3.1] - 2026-02-21

### Changed
- Theme collection rebalanced: every palette was reworked and the themes
  are now organized by hue family (near black, dark slate, navy, blue,
  teal, green, purple, red/burgundy, brown). Ten themes added (`athenee`,
  `axiom`, `excellence`, `graphite`, `mineral`, `nocturne`, `prestige`,
  `renaissance`, `sequoia`, `studio`) and eight removed (`cambridge`,
  `cardinal`, `cosmos`, `flora`, `glacier`, `night`, `oxford`, `tweed`).
  The default theme is now `axiom` (was `oxford`).
- Semantic color mapping adjusted: `theoremColor` and `methodColor` now
  use the secondary palette color, `subsubsectionColor` the structural
  color; `codeTitle` and `codeFrame` are swapped; code token colors are
  mixed with `globalcolor` instead of pure black (better on dark themes).
- Several `profile` presets retuned (`swiss`, `slate`, `maker`, `moss`,
  among others) with different theme and template combinations.
- Table of contents entries and their dotted leaders are now colored per
  level; `sidebyside` derives its colors from `codeFrame` instead of
  `exampleColor`; `neobox` body text now uses `globalcolor`.
- The `frenchmath` option has been removed.

### Fixed
- `compacttoc` now works on its own; previously it only took effect when
  `twocoltoc` was also set.

## [1.3.0] - 2026-02-09

### Added
- New `profile` option with 16 ready-made document presets (`academic`,
  `minimalist`, `material`, `coder`, `memo`, `exam`, `organic`, `origami`,
  `blueprint`, `swiss`, `creative`, `focus`, `elegant`, `slate`, `maker`,
  `zen`), each preconfiguring theme, title layout, theorem/exercise/
  admonition/code styles and opacities. Explicitly given options always
  override the preset.
- New `darktheme` option: renders any theme on a dark page background with
  light text, palette colors being lightened for contrast.
- Many new decorative title layouts for `titlelayout`: `band`, `bar`,
  `bauhaus`, `blocks`, `book`, `bristol`, `brush`, `champagne`, `circles`,
  `cloud`, `confetti`, `flow`, `grid`, `magazine`, `memphis`, `notion`,
  `particles`, `simplenotion`, `spine`, `stream`, `tech`, `wave`, plus the
  classic `minimal` and `frame` layouts.
- New named theorem styles with matching constructors `\newtagtheorem`,
  `\newbartheorem`, `\newblocktheorem`, `\newcurvetheorem`,
  `\newfoldtheorem`, `\newframetheorem`, `\newpasteltheorem`,
  `\newplaintheorem`, `\newstickertheorem`, `\newtiletheorem` and
  `\newrawtheorem`, replacing `\newamstheorem`, `\newboxedtheorem`,
  `\newclassictheorem`, `\newclassytheorem`, `\neweleganttheorem`,
  `\newleftruletheorem`, `\newshadedtheorem`, `\newslantedtheorem` and
  `\newsobertheorem`.
- Exercise display templates redesigned and renamed: `badge`, `bar`,
  `block`, `capsule`, `card`, `counter`, `curve`, `digit`, `fold`,
  `frame`, `line`, `pastel`, `plain`, `rule`, `separator`, `shell`,
  `sticker` and `tile`, with `-outline` and `-inline` variants (replacing
  the former `box-hrule`, `boxed`, `classic-box`, `classy-box`,
  `elegant-box`, `num-box`, `rect-box`, `shaded-box`, `slanted-box`,
  `smart-box`, `sober-box` and `terminal` templates).
- New `adstyle` option selecting the admonition style by name.
- Solutions: new `solstyle` option (default `inline`, with `lines`, `dots`
  and `box` styles backed by the new `sol-lines`, `sol-dots` and `sol-box`
  templates), replacing the `blocksol` option; new `solrotate` option
  printing solutions upside down (180-degree rotation).
- New plural theorem environments `definitions` and `properties`.
- New `mathraster` environment laying out equations in a grid of boxes.
- New `inlineabstract` option.
- Fine-grained box appearance options: corner shapes (`boxshape` with
  `thmboxshape`, `exboxshape`, `codeboxshape`, `neoboxshape`,
  `sideboxshape`, `thmtitleshape`, `thmtitlearc`, `sectionarc`,
  `neoboxarc`), border thicknesses (`border`, `thmborder`, `exborder`,
  `codeborder`, `adborder`), frame opacities (`frameopacity`,
  `thmframeopacity`, `exframeopacity`, `codeframeopacity`,
  `adframeopacity`, `sideframeopacity`, `neoframeopacity`), global
  `padding`, and the `exframe`/`exnoframe` pair.
- New `secondarymix` and `tertiarymix` options (0-100, default 85)
  controlling how strongly the secondary and tertiary palette colors are
  blended.

### Changed
- Theme system rebuilt around four-color palettes (primary, secondary,
  tertiary, structural) mapped onto all semantic colors; 56 themes with
  academic names (`oxford` as default, `harvard`, `cambridge`, `eton`,
  `ivy`, `trinity`, `ink`, ...) replace the 1.2.0 collection.
- `method` and `activity` are now admonition-type environments; the
  `application` theorem environment has been removed.
- `print` is a plain boolean option again and `unicolor` a color mode; the
  1.2.0 `accent`, `colorprofile` and `bicolor` options have been removed.
- `twocolumntoc` renamed to `twocoltoc`.

## [1.2.0] - 2025-12-07

### Added
- New `titlelayout` option selecting the title page by name
  (`titlelayout=exam`, `eval`, `bubbles`, ...); the individual layout
  class options (`eval`, `evalicons`, `evalgrade`, `evaliconsgrade`,
  `exam`, `mockexam`, `shortexam`, `shorteval`, `bubbles`, `topbubbles`,
  `bottombubbles`, `titlebox`, `tighttitle`, `onlytitle`, ...) become
  values of this single option. New `geometric` and `banner` layouts.
- Theme collection replaced: over sixty new themes organized in seven
  families (Modern, Blue, Green, Red, Brown, Purple, Dark), with
  `midnight` as the new default. The Dark family (`dracula`, `night`,
  `mocha`, `nord`) introduces the first dark themes: dark page background
  and light text set automatically.
- New `accent` option (default `light`) controlling how theme colors are
  applied: `strong`, `emphasized`, `gradient`, `soft`, `flat`,
  `structured`, `minimal`, `mono`, `technical`, `print` and `accessible`.
  Replaces the `print` boolean option (use `accent=print`).
- New `colorprofile` option assigning palette colors to environment types:
  `mathbook` (default), `exam`, `core`, `school`, `unicolor`, `bicolor`.
- Background opacity options: `boxopacity` (global), `thmboxopacity`,
  `exboxopacity`, `codeboxopacity`, `adboxopacity`, `mathboxopacity`.
- Global appearance toggles `back`/`noback` and `frame`/`noframe`, with
  the `clean` (all frames and backgrounds off) and `styled` (all on)
  shortcuts, plus the `exback`/`exnoback` pair.
- Title terminator and separator options: `thmterminator`, `thmseparator`,
  `adterminator`, `exterminator`.
- Font scaling options `mainfacescale`, `sansfacescale`, `monofacescale`;
  automatic detection of a SemiBold weight for the selected fonts,
  exposed as `\sbseries`.
- New `titlesize` option, and `titledecor` replacing the `titlerule`,
  `titlemidrule`, `titlefullrule` and `titleornament` options.
- New `headerules` option (`headrule`, `footrule`, `headfootrule`, `none`)
  replacing the three boolean rule options of the same names.
- New `noteswidth` and `notesposition` options for margin notes.
- New `\newleftruletheorem` constructor and `leftrule-box` exercise
  template.

### Changed
- Theorem visual styles are now selected exclusively through `thmstyle=`;
  the boolean options `amslikethm`, `classicthm`, `classythm`,
  `elegantthm`, `shadedthm`, `slantedthm`, `soberthm` and `boxedthm` have
  been removed.
- Admonitions are declared through a single generic mechanism; the eight
  environments and their behavior are unchanged.
- Default horizontal `margin` raised from `1cm` to `1.5cm`.
- Box corner radii now default to `0pt` (square corners) for all box
  families except exercises (`exboxarc` defaults to `2pt`).
- The `graphics` option has been removed; `wrapfig` is always loaded and
  `graphicx` remains available through TikZ.

## [1.1.3] - 2025-11-14

### Added
- New `titlebox` title layout: title, with optional subject and subtitle,
  set in a full-width tinted banner at the top of the page, honoring
  `titlealign`.
- New `tighttitle` layout: the same compact header without the banner and
  with reduced vertical space.
- New `noexback` option removing the background color of exercise boxes
  only.

### Changed
- The `theoremstyle` and `exercisestyle` options are renamed `thmstyle`
  and `exstyle`.
- The `fancybox` title layout (rotated corner banner) has been removed in
  favor of `titlebox`.
- Exercise headings normalized across all templates: the points group is
  set with a non-breaking space before `point`/`points`, the dot
  separators are placed consistently around difficulty stars, subtitles
  and points, and the `bonus-points` property is no longer displayed in
  headings.
- The grade title block (`evalgrade`, `evaliconsgrade`) now positions its
  duration and name fields according to the presence of a subject and
  subtitle, and uses the localized strings introduced in 1.1.1 instead of
  hard-coded French labels.
- Title decorations get more room above (`2\titlespacing`), and the
  vertical spacing of the built-in title layouts is now expressed in
  `\baselineskip` units; right-aligned titles use `\raggedleft` directly.

## [1.1.2] - 2025-11-11

### Added
- New `boldlistlabels` option: bold labels in `enumerate` lists
  (`1.`, `a.`, ...).
- New `leftnotes` and `rightnotes` options: margin notes confined to the
  left or the right margin (`notes` keeps alternating between both).
- New `mathfacescale` option: scaling factor for the math font under
  LuaLaTeX and XeLaTeX.
- New `shaded` and `shadedline` section styles for `sectionstyle`.

### Changed
- `mismath` (and `mathtools` through it) is no longer loaded; the class
  now relies on `nccmath`, which provides `amsmath`.
- `\mrks` has been removed: `\mrk` now pluralizes `point`/`points`
  automatically.
- Exercise difficulty stars are rendered by the new `\neoexerciserating`
  helper, which compensates for `mathfacescale` so the stars keep a
  consistent size.

## [1.1.1] - 2025-11-02

### Added
- Six new themes: `coral`, `earth`, `modern`, `neon`, `nordic`,
  `twilight`. The theme selector now warns and falls back to `classic`
  when the requested theme is unknown.
- New `examcolor` option remapping practical and admonition colors onto
  the main theory color (`definitionColor`) for a uniform two-tone
  palette suited to exams.
- Per-family frame, background and numbering toggles: `thmframe`/
  `nothmframe`, `thmback`/`nothmback`, `codeframe`, `codeback`/
  `nocodeback`, `codenum`/`nocodenum`, and `adframe`/`noadframe`,
  `adback`/`noadback` (admonitions are borderless and unfilled by
  default). They replace the global `noback`/`noframe` options.
- New `vspacing` option: a global factor (default `1.0`) compressing or
  expanding vertical spacing (paragraphs, lists, headings). Replaces the
  `compact` option.
- Corner-radius options per box family: `thmboxarc`, `exboxarc`,
  `codeboxarc`, `adboxarc`, `sideboxarc` (complementing `boxarc`).
- New `codestyle` option (default `box-elegant`) selecting the default
  code box style, replacing `lststyle`; `\setcodestyle` has been removed.
- New `theoremstyle` and `exercisestyle` options selecting theorem and
  exercise styles by name, as an alternative to the boolean style
  options.
- New footer options: `nofooter` (empty page style) and `pageonlyfooter`
  (centered page number only).
- New `bottombubbles` title layout (bubbles at the bottom of the page,
  title above); the `shortbubbles` layout has been removed.
- New `\answerfield[width]{lines}` command: answer area with a colored
  background, companion to `\answerframe`.
- New `\AILogo` and `\NoAILogo` commands drawing an AI chip badge with a
  localized label (AI/IA/KI), to mark AI-assisted or AI-free content.
- The calculator notice and the mock-exam cover strings are now localized
  in the three languages (they were hard-coded in French).

### Changed
- `inlineadmonition` is now enabled by default; the new `blockadmonition`
  option restores the title-above-body layout.
- The `academic`, `emphasis` and `practical` color modes introduced in
  1.1.0 have been removed (superseded by `examcolor` and `unicolor`).

## [1.1.0] - 2025-10-25

### Added
- Theme collection expanded from 9 to 30 themes, defined through a new
  five-color palette mechanism applied consistently to every environment.
  New themes: `abyss`, `aether`, `atlantic`, `autumn`, `blossom`,
  `botanical`, `burgundy`, `day`, `deepocean`, `eagle`, `foresthues`,
  `glacier`, `goldensummer`, `graphite`, `heather`, `heritage`, `magma`,
  `midnight` (dark), `purplebliss`, `retrocafe`, `saffronsky`, `scribe`,
  `sepia`, `summer`, `winkle`. The `spring`, `arbutus`, `navy` and
  `royal` themes have been removed.
- New color application modes: `emphasis` (theory colored, the rest in
  gray), `practical` (methods, applications and code colored) and
  `academic` (two distinct color families). They replace the `normal` and
  `gradientheadpalette` palettes.
- Table of contents options: `compacttoc` (reduced spacing), `monotoc`
  (single color) and `twocolumntoc` (two columns).
- New `inlinecodebox` option: inline code (`\texttt`) in a small framed,
  colored box.
- Code listing variants with and without line numbers: `codenonum`
  environment, `\codeinputnum` and `\codeinputnonum` commands.
- `\answerframe` accepts a new trailing optional argument passing
  `tcolorbox` options.

### Changed
- Hyperlink colors now follow the active theme and adapt to the `print`
  and `unicolor` modes.
- Exercise template names consolidated: the `...-outlined` variants are
  renamed `...-out`; the `box`, `noframe-box` and `subsection` templates
  are removed.
- The `\solutionbox` and `\secpunct` commands have been removed.

## [1.0.6] - 2025-09-13

### Added
- New `sol-dotted` solution template: the solution heading is extended by
  a dotted rule and the solution body is closed by a full-width dotted
  rule.

### Changed
- `sol-block` redesigned: heading followed by a thin rule filling the
  line, body closed by a full-width rule. Both block templates now
  reserve space (`\needspace`) so a solution heading cannot be stranded
  at the bottom of a page, and forbid a page break before the closing
  rule.
- Untitled code blocks with the default box style now sit much closer to
  the surrounding text (before/after skip reduced to
  `0.1\baselineskip`).
- Admonition boxes get more vertical breathing room (before/after skip
  raised from `0.5\baselineskip` to `\baselineskip`).

## [1.0.5] - 2025-08-27

### Added
- New `answersonly` option printing only the solutions; `\correct` and
  `\correct*` reveal the correct answers under it, as with `answers`.
- New `topbubbles` title layout: bubble cloud confined to the top of the
  page with the title below. The `bubbles` layout is redesigned: the
  title now sits on a translucent white card with a soft shadow inside
  the cloud, and both layouts display the subtitle.
- New `blocksol` option selecting the `sol-block` solution template.
- New `inlineadmonition` option: admonition title and content on the same
  line.
- Landscape support: the text area and the `margin` option now adapt when
  the paper is wider than tall.

### Changed
- Solution rendering: the tinted `sol-box` template is replaced by the
  plain `sol-inline` template (new default) and the `sol-block` template.
- Default `margin` raised from `.25cm` to `1cm`; `\columnsep` doubled to
  `2em` in two-column mode; vertical spacing under the built-in title
  layouts retuned for one- and two-column documents. The `evalgrade`
  layout no longer inserts a `\gradingstrip` below the header.
- `\withqrcode` tables now span the full line width.

### Fixed
- Font loading rewritten around `iftex` with a dedicated XeLaTeX branch:
  XeLaTeX no longer receives the LuaTeX-only HarfBuzz renderer.
- LuaLaTeX defaults corrected: roman font fixed from the nonexistent
  `TeX Gyre PagellaX` to `TeX Gyre Pagella`; default monospace switched
  from `Cascadia Code` to the always-available `TeX Gyre Cursor`; a
  custom `mathface` is now loaded through `unicode-math` and
  `\setmathfont` instead of `\RequirePackage`.

## [1.0.4] - 2025-07-20

### Changed
- Exercise headings: the space before the points group is now a thin
  space (`\,` instead of `\enskip`).

## [1.0.3] - 2025-07-19

### Added
- New `proof` environment with localized name (Proof, Démonstration,
  Beweis) and a closing QED square, styled to match the active theorem
  style.
- New `codewidth` option (factor of `\linewidth`, default `1`) and
  `centeredcode` boolean option; the `code` environment and `\codeinput`
  accept a trailing optional argument overriding the width per block.
- The `pifont` package (Zapf Dingbats symbols) is now loaded.

### Changed
- Default `lststyle` is now `colorfuln`: code blocks show line numbers by
  default (small gray sans-serif, `numbersep=14pt`); `minted` listings
  also get line numbers by default, and use the `bw` style under `print`.
- Selecting `minted` no longer activates `listings` as well; `listings`
  remains the default engine when neither option is given.
- The default code box style now renders a styled title when one is given
  instead of forcing `notitle`; the `box-classic` code box style has been
  removed.
- The `margin` option now defaults to `.25cm` instead of leaving the
  computed type area untouched.

### Fixed
- `\setcodestyle` now applies the chosen style immediately (`\lstset`);
  previously it only affected the default of later code boxes.
- `print` mode also converts `remarkColor` to black, and the minted `bw`
  style is applied during the minted setup rather than at option
  processing time.

## [1.0.2] - 2025-07-11

Maintenance release: version metadata refresh only, no functional change
to the class.

## [1.0.1] - 2025-05-26

### Added
- New `\shorttitle` command providing an alternative title for the footer
  of the following pages; without it, titles longer than 85 characters
  are truncated there with an ellipsis.
- The `\neoheader` field defaults are now preset and applied even when the
  command is never called (previously some fields could end up
  undefined).

### Changed
- `bubbles` and `shortbubbles` layouts: title and subtitle now wrap
  inside a fixed text width instead of overflowing on long titles; header
  heights and the space after the title block are adjusted.
- Grade title layouts: narrower title width (`0.75\textwidth`) and higher
  position on the page.

### Fixed
- Conflict between the `math` option and `tdsfrmath` over `\mathscr`
  (the command is now reset before other math packages load).
- The `conjecture` theorem referenced an undefined color macro; it now
  uses `remarkColor`.
- The calculator notice comparison was rewritten with `\ifx` (more robust
  than `\pdf@strcmp`); invalid `calculator` values still raise an
  explicit error.

## [1.0.0] - 2025-01-04

Initial release.

- Document class for secondary-school teachers, built on KOMA-Script
  `scrartcl`, with pre-configured title and header layouts for
  assessments, exams and lesson handouts.
- Color themes, theorem-like environments, exercises with solutions
  (based on `xsim`), code listings, admonitions, and dozens of commonly
  used packages preloaded to keep preambles short.
- English, French and German localization.
