CTAN update: xpinyin
by CTAN Announcements via ctan-ann 30 Sep '26

30 Sep '26

Liam Huang submitted an update to the xpinyin package. Version: 3.2 2026-09-27 License: lppl1.3c Summary description: Automatically add pinyin to Chinese characters Announcement text: -------------------------------------------------------------------------------- xpinyin v3.2 brings new commands for querying pinyin data, broader input support, updated Unicode data, and several bug fixes. NEW FEATURES - `\disablepinyin` now has a starred form that also covers the `\xpinyin` command itself. (#265) - Four new commands `\xpinyinvalue`, `\xpinyininitial`, `\xpinyinshengmu`, and `\xpinyinyunmu` for querying the pronunciation of individual characters, useful for Chinese index grouping and sorting; the data table is loaded on demand via the `query` option. (#550) - Pinyin arguments now accept `ü`/`Ü` directly, equivalent to the existing `v`/`V` notation. Previously `\pinyin{nü3}` produced the literal text `nü3` under XeTeX, and caused an error under pdfTeX with `CJKutf8`. (#1069) BUG FIXES - When xeCJK's `AutoFallBack` has switched to a fallback font, the box used for width measurement no longer reselects the main font, fixing ruby text being compressed to an incorrect width. (#997) - `\setpinyin` now also updates the query table for characters not in the built-in database; previously only the ruby table was updated while `\xpinyinvalue` still reported "no pronunciation". (PR #1051) - `\setpinyin` now strips the trailing `5` (neutral tone marker) when storing to the query table, consistent with the convention that the query table omits the digit for neutral tone; previously the `none` form returned `shi5` instead of `shi`. (PR #1051) OTHER CHANGES - Pinyin data updated to Unicode 18.0 Unihan (v3.1 used 14.0), adding pronunciations for about 3,000 more characters; the preferred reading of about 300 characters has changed accordingly, mostly corrections to the current standard pronunciation, e.g. "绩" changed from `jī` to `jì`. The characters "子", "們", "啊", "啦", and "哇" retain their original neutral-tone readings. Use `\setpinyin` to override when needed. - Added standalone regression tests and integrated version-consistency checks for tag-based release builds. This only affects the test and release workflow, not the package behavior.

FYP submitted the mpformulation package. Version: 2.0 License: lppl1.3c Summary description: Typesetting mathematical programs (optimization models) Announcement text: -------------------------------------------------------------------------------- mpformulation typesets mathematical programs (linear, integer and nonlinear optimization models) the way they appear in operations research journals: a named objective, a "subject to" line, and one constraint per line with its quantifier (for all i in I) and an equation number. Main features: - "subject to" and the final period of the model are added automatically; - numbering per constraint, per model with sub-numbers (1a, 1b, ...), or a single number for the whole model; labels for the model number and the model name; - constraints too wide for the line, e.g. in two-column journals, are reorganized automatically: the indent shrinks, the quantifier is broken at its commas or moved below, and optional break points can be given in long expressions and objectives; - optional alignment of the constraints on their relation symbol, and left-aligned quantifiers in a common column; - no page break after the objective or "subject to", nor before the last constraint. The package is configured with key-value options, globally or per model. The manual introduces each feature with an example. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/mpformulation More information is at https://ctan.org/pkg/mpformulation -------------------------------------------------------------------------------- Thanks for the upload.

Version: 1.4 License: lppl1.3c Summary description: Single-pass cross-references, page totals, TOC and citations for LuaLaTeX Announcement text: -------------------------------------------------------------------------------- Version 1.4 adds single-run numbered citations: \cite against a hand-written thebibliography (or an existing BibTeX .bbl) resolves in the same single LuaLaTeX run, including forward citations, multi-key lists and the optional note; natbib/cite/biblatex are detected and left untouched.

Volker Reichenberger submitted an update to the nxtlatex package. Version: 1.3 License: lppl1.3c ofl Summary description: Classes and themes for faculty NXT (Reutlingen University) Announcement text: -------------------------------------------------------------------------------- nxtlatex 1.3 provides LaTeX classes and themes for the faculty NXT Sustainability and Technology at Reutlingen University: a thesis class, a letter class option and a Beamer theme. All components require LuaLaTeX. Changes in version 1.3: - nxtthesis is now based on the standard class report instead of KOMA-Script scrreprt. With \DocumentMetadata{..., tagging=on} it produces tagged, accessible PDFs; veraPDF confirms PDF/UA-2 for all twelve font options and for the example thesis. When tagging is active, the class loads the tagging support for listings. Layout and appearance are unchanged; \subtitle, \addchap and \addsec are still available. - The declaration of academic integrity follows the faculty's guideline of December 2025, including the required statement on AI tools (option ki=...) and an optional partner university. - New class options: richtlinie (the faculty's mandatory layout), kapitaelchen (headings in small caps) and logo, plus seven new font options (now twelve). With the option english, the title page is now in English as well. - Lists of abbreviations (\akronym, based on acro) and symbols (\Symbol, \printsymbols); \kapitaelchen sets small caps only where the current font shape has them. - The NXT logos are now glyphs in the included NXT Logo Font 1.0 (OFL), taken unchanged from the faculty's corporate design. No download is needed any more. The logo macros support all colour schemes of the corporate design, including CMYK, and provide alternative texts. - Title, author and language are written to the PDF metadata; PDF/A via \DocumentMetadata no longer produces a duplicate OutputIntent. - nxtbrief now uses fontawesome5, and the package ships a TDS archive, so nxtbrief.lco is installed where TeX finds it. The Beamer theme file is now named beamerthemeNXT.sty, matching \usetheme{NXT}. - A complete example thesis with sources and a German introduction to LaTeX with the class (PDF) are included. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/nxtlatex More information is at https://ctan.org/pkg/nxtlatex -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 25 Sep '26

25 Sep '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-09-24 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: -------------------------------------------------------------------------------- ## expltools 2026-09-24 ### explcheck v0.24.0 #### Fixes This version of explcheck has fixed the following problems: - Ignore LaTeX3 standard-library commands newer than the value specified by the Lua option `latex3_definitions_max_added_date`. (#231) Since explcheck v0.20.0 from 2026-05-03, the option had no effect due to a typo. #### New features This version of explcheck has implemented the following new features: - Export the version date of the LaTeX3 data files as `expl3_version` in the `explcheck-latex3.lua` module. (#219, #231) - Include the dates when function and variable definitions were last updated in `definitions` from `explcheck-latex3.lua`. (#219, #231) This has increased the file size from circa 187K to circa 233K (+25%). - Include lone macro definitions with no corresponding function or variable definitions in `explcheck-latex3.lua`. (#219, #231) Previously, `\begin{macro}` definitions in `l3*.dtx` files were disregarded unless the same control sequence also had corresponding `\begin{function}` or `\begin{variable}` definitions. After this change, macros without corresponding `\begin{function}` or `\begin{variable}` definitions are classified as functions or variables based on their names. This has increased the number of function definitions in `explcheck-latex3.lua` from 4,883 to 5,637 (+15%) and the number of variable definitions from 340 to 371 (+9%). This has further increased the file size from circa 233K to circa 247K (+6%). Overall, the size of `explcheck-latex3.lua` has increased from circa 187K to circa 247K (+32%) in this version of explcheck. - In the command-line `--verbose` output, display the declared and estimated version of LaTeX3 required by the package files. (suggested by @dcpurton in #219, added in #231) For example, here is the output of running explcheck with the `--verbose` option on the files `markdown.tex` and `markdown.sty` from version 3.16.0 of the Markdown package for TeX from TeX Live 2026: ``` Checking 2 files Checking /usr/local/texlive/2026/texmf-dist/tex/generic/markdown/markdown.tex OK [...] Preprocessing results: - Doesn't seem like a LaTeX style file - Declares no required LaTeX3 version [...] Required LaTeX3 version estimates: - Latest added LaTeX3 command: \tl_if_regex_match:nNTF (2024-12-08) - Latest updated LaTeX3 command: \sys_if_engine_luatex:TF (2026-07-20) - Earliest deprecated LaTeX3 command: \regex_match:Nn (2025-05-14) [...] [...] Checking /usr/local/texlive/2026/texmf-dist/tex/latex/markdown/markdown.sty OK [...] Preprocessing results: - Seems like a LaTeX style file - Declares no required LaTeX3 version [...] Required LaTeX3 version estimates: - Latest added LaTeX3 command: \msg_info:nnnn (2021-05-18) - Latest updated LaTeX3 command: \cs_gset_protected:Npn (2023-09-27) [...] [...] Aggregate statistics: [...] - Required LaTeX3 version: undeclared, estimated at 2024-12-08 or later [...] ``` This allows package authors to determine how recent a version of `l3kernel` their code requires. Note that some obfuscated LaTeX3 commands may be missed by the analysis and that only the latest added date, not the latest updated date, is considered in the final recommendation in the "Aggregate statistics" section. The reported version should therefore be treated as a lower-bound estimate that requires human verification. - Report a warning when a standard-library LaTeX3 command is too recent. (discussed with @dcpurton in #219, added in #231) This adds two new warnings W210 and W306, titled "LaTeX3 command too recent", to sections 2 and 3 of the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors] and implements them. These warnings are raised when a package file uses standard-library LaTeX3 commands introduced after the date specified by the Lua option `latex3_definitions_max_added_date`. A possible workflow is to run `explcheck --verbose` on your package and pin the reported required LaTeX3 version (e.g., `2024-12-08` in the example above) using `\NeedsTeXFormat{LaTeX2e}[2024-12-08]` and/or `\RequirePackage{expl3}[2024-12-08]`. Alternatively or additionally, set the Lua option `latex3_definitions_max_added_date` to `"2024-12-08"` in your `.explcheckrc` config file. If you later use newer LaTeX3 commands, these warnings will prompt you to either raise the required version or replace those commands. #### Documentation This version of explcheck has made the following improvements to the documentation: - In the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors], grey out labelled work-in-progress issues. (reported by @muzimuzhi in #227, fixed in #228) Previously, labelled issues were assumed to be finished, whereas issues with automatically generated identifiers were assumed to be work-in-progress. However, some recent issues, like W512 (Defined an unexpandable function as unprotected), are labelled, since other issues already refer to them, but they are still marked as a work in progress. After this change, these issues are no longer considered finished and are properly designated as unfinished in the documentation. #### Continuous integration This version of explcheck has made the following changes to our continuous integration (CI): - Check if the `latex3` submodule points to the latest stable release. (reported by @muzimuzhi in #226, fixed in #229) Previously, the CI would nudge us to update the `latex3` submodule to the latest development version of LaTeX3, which would cause the file `explcheck-latex3.lua` to include bleeding-edge information from the LaTeX3 files `l3obsolete.txt`, `l3prefixes.csv`, and `l3*.dtx`. However, as mentioned by @muzimuzhi in #226, "in most cases, packages are written to work with stable [...] releases". This preference was corroborated by @u-fischer in the same ticket. Therefore, after this change, the CI will nudge us towards the latest stable rather than development releases. - Check if the `latex3` submodule points exactly to a Git tag. (#229) #### Dependencies This version of explcheck has made the following changes to third-party Git submodules and other dependencies: - Update the `latex3` submodule from 2026-09-09-dev to 2026-09-09 and continue pinning stable rather than development releases.

Version: 3.9 2026-09-23 License: lppl1.3c Summary description: Worlds and block programs of the German teaching environment Robot Karol Announcement text: -------------------------------------------------------------------------------- robotkarol draws worlds and Blockly-style block programs in the visual style of Robot Karol Online (https://karol.arrrg.de/) for worksheets, exams and slides. New in version 3.9: a karolwelt picture can show the start state and the goal state of a task at once, the way the online exercises do. The objects take the keys start and ziel -- with the aliases neu and weg, and the Robot Karol verbs hinlegen/aufheben and setzen/loeschen -- as well as startanzahl and zielanzahl for stacks that grow or shrink. The environment gained zustand=start|ziel|beides to pick the view, aufraeumen for tasks whose goal is the empty world, and rahmen and hervorheben. The new karolweltpaar environment draws one world twice, as a before-and-after pair, and \karolzustandslegende explains the symbols. The print mode covers all of this by hatching and dashed outlines rather than by shades of grey. Documents that do not use the new keys produce byte-identical output. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/latex/robotkarol More information is at https://ctan.org/pkg/robotkarol -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: chemidentifier

Aliocha Skrzypczak submitted an update to the chemidentifier package. Version: 2.0.1 2026-09-20 License: lppl1.3c Summary description: Synthesis-order numbering and hyperlinking of chemical compounds Announcement text: ------------------------------------------------------------------------ ### Fixed - `\chemidscheme` crashed with a raw Lua error (`attempt to index a nil value`) when used before any `\chemidkey` or `\chemidnote` had run earlier in the document. An unlabelled scheme (a lone structure, a graphical abstract, a figure whose labels are already typeset) is a legitimate use of `\chemidscheme` and is now simply typeset verbatim. Fixed identically in `chemidentifier-v2.sty` and the frozen `chemidentifier-v1.sty`. - The text substitution performed by `\chemidscheme` was a plain, unanchored substring replacement applied to *every* line of the `.pdf_tex`, including the `\includegraphics` line. A motif that happens to be a substring of the companion PDF's file name — easy to trigger, since both are usually named after the compound — rewrote the image path itself and broke the figure with an obscure `\csname` error. The `\includegraphics` line is now left untouched, and a new warning names the motif and the figure when this would have happened, instead of failing silently downstream. ### Changed - **`links` (version 2, `\chemidsetup`) now defaults to `false` instead of `true`.** Compounds are typeset as plain numbers by default; add `links=true` — as a package option (`\usepackage[links=true]{chemidentifier}`) or via `\chemidsetup` — to restore clickable links and anchors as before. This only affects version 2 (`\usepackage[version=2]` or the default); version 1 has no `links` key and is unaffected. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/chemidentifier The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/chemidentifier/ ------------------------------------------------------------------------ Thanks for the upload.

Christophe Jorssen submitted the luacoolprop package. Version: 1.1.0 License: lppl1.3c Summary description: Thermodynamic calculations and diagrams in LuaTeX via the CoolProp shared library Announcement text: -------------------------------------------------------------------------------- This package was vibe-coded with the assistance of ChatGPT. AI-generated code and thermodynamic results require independent review; the README and manual warn users accordingly. Full --shell-escape is required for the LuaTeX FFI mechanism and can execute arbitrary commands with the user permissions, so only trusted documents should be compiled. The upload ZIP contains a browsable luacoolprop/ tree and a separate luacoolprop.tds.zip at its root. CoolProp source and binary files are external dependencies and are not included. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/generic/luacoolprop More information is at https://ctan.org/pkg/luacoolprop -------------------------------------------------------------------------------- Thanks for the upload.
