CTAN update: scholatex

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.
