CTAN update: scholatex
by CTAN Announcements 30 Jun '26

30 Jun '26

Gérard Dubard submitted an update to the scholatex package. Version: 2.3 License: gpl3+ Summary description: A tag-based language for print-ready teaching worksheets, built on LuaLaTeX Announcement text: -------------------------------------------------------------------------------- scholatex 2.3 — this release brings together the additions of versions 2.2 and 2.3. Figure drawing (2.3): the new <draw> block renders plane geometric figures from a description alone — the shape is named, its measurements given, and coordinates are computed trigonometrically and emitted as hard TikZ numbers. It covers triangles by every classical definition, quadrilaterals (square, rectangle, rhombus, parallelogram, trapezoid, kite), regular polygons by name or point count, and circles (by centre and radius, circumscribed through three points, or inscribed). Equal-side and right-angle marks and per-side length labels are opt-in, with single and double ticks telling apart pairs of different lengths. Composite figures share points and edges; loops, rotation and low-level point and line primitives allow free-form drawings. Mathematical vocabulary (2.2): the inline maths mini-language gains a full probability and statistics vocabulary (blackboard operators, spread, distributions, distribution and density functions), counting (binomial coefficient, arrangement, factorial), named linear-algebra operators, differential operators, Landau notation, integral transforms, surface and volume integrals, number theory, and calculation templates. Fixes include extensible parentheses over a fraction, higher-order differentials, and clearer plot axes. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/latex/scholatex More information is at https://ctan.org/pkg/scholatex -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: zhlineskip
by CTAN Announcements 29 Jun '26

29 Jun '26

Mingyu Xia submitted an update to the zhlineskip package. Version: 1.0f 2026-06-28 License: lppl1.3c Summary description: Line spacing for CJK documents Announcement text: ------------------------------------------------------------------------ The zhlineskip package provides tools for typesetting CJK documents with Microsoft Word–compatible line spacing. Version 1.0f is a significant internal overhaul that also streamlines the user-facing option interface. ### BREAKING CHANGES - The boolean option `UseMSWordMultipleLineSpacing` has been removed. Its functionality is now integrated into the `MSWordLineSpacingMultiple` option. Users who previously set `UseMSWordMultipleLineSpacing=true` should migrate to `MSWordLineSpacingMultiple=<value>` directly; the multiple-line-spacing feature activates automatically when a value is supplied. Documents that relied on the old boolean key will produce an "unknown option" error and must be updated. ### BUG FIXES - Fixed a line-spacing restoration leak in the `split` environment (from amsmath) that caused incorrect vertical spacing around display-math blocks. The internal spacing-restore scope now closes correctly at the end of `split`, so `\abovedisplayskip` and `\belowdisplayskip` behave as expected in surrounding text. ### INTERNAL CHANGES - The package internals have been rewritten in LaTeX3 (expl3). The former dependencies on the `kvoptions` and `xintexpr` packages have been dropped entirely. Option parsing now uses `l3keys`, and all fixed-point arithmetic is handled by the `l3fp` module shipped with the LaTeX kernel. This eliminates two external runtime dependencies, reduces package load time, and aligns the codebase with modern LaTeX3 conventions. The public interface remains unchanged apart from the option consolidation noted above. ### Compatibility notes - TeX Live 2020 or later is required (for a sufficiently recent expl3). - No other user-visible behaviour has changed; existing documents that do not use the removed `UseMSWordMultipleLineSpacing` option should compile without modification.

CTAN update: xecjk

26 Jun '26

Liam Huang submitted an update to the xecjk package. Version: 3.10.0 License: lppl1.3c Summary description: Support for CJK documents in XeLaTeX Announcement text: -------------------------------------------------------------------------------- xeCJK v3.10.0 is a major release focused on Chinese inter-character spacing (CJKglue/CJKecglue) correctness across whatsit-bearing contexts, with broad fixes and a few breaking changes. Highlights: NEW FEATURES * New \xeCJKchar command bypassing interchar handling, replacing the earlier \char redefinition that broke xint and other packages (resolves #407, #800). * New experiment/halfright-prebreakpenalty option (#811). * New experiment/punct-measure-fix option for paragraph-mode punctuation-compensation glue eaten by \unskip. * New NoBreakLongPunct character property forbidding line breaks before long punctuation such as ellipses. * Document fonts unified to Noto Serif CJK; xunicode-symbols.tex now uses a five-level per-character font fallback chain (FreeSerif -> Noto Sans Symbols 2 -> Symbola -> Segoe UI Symbol -> DejaVu Sans) for #878. * Unicode data resynchronised through Unicode 17.0 (with 15.0 / 15.1 catch-up). BUG FIXES (CJKglue / CJKecglue / boundary recovery) * \textcolor and other color whatsit nodes no longer drop CJKecglue on either side (#807, #809, #810, #831, #832). * \textcolor wrapping ulem-family underline commands no longer corrupts CJK inter-character spacing (#830). * Spurious inter-word glue after explicit "}", \mbox and \textcolor is suppressed (#831). * hyperref link annotations preserve CJKecglue across the \Hy@BeginAnnot whatsit (#809, #810). * xeCJKfntef commands no longer leave a stray space on their right side; font-state and \g_@@_last_node_tl are now saved across the hbox (#465, #826). * hypdoc \HD@target hbox and url \Url@FormatString math entry no longer shadow boundary markers (#873, #880). * \lstinline now preserves the character code of catcode-6 tokens beyond '#' (e.g. when \catcode`\&=6) (#879). * Trailing space after a CJK character before a macro is no longer emitted as glue prematurely. * xCJKecglue option and \xeCJKnobreak handling corrected. BREAKING CHANGES * \newCJKfontfamily now defines its font-switching command locally instead of globally (#751/PR #773). * Removed compatibility shims for LaTeX2e versions older than 2020/10/01 (#746). * Minimum LaTeX3 (expl3) version raised to 2025/10/09. DEPRECATED * \xeCJKsetcharclass is deprecated. Full ChangeLog (per \changes{v3.10.0} entries) is available in the package documentation.
