CTAN update: numodel-bundle
by CTAN Announcements 08 Sep '26

08 Sep '26

Paul Zuurbier submitted an update to the numodel-bundle package. Version: 0.9.1 2026-09-07 License: lppl1.3c Summary description: Numerical physics models with Forrester diagrams and auto-sized plots Announcement text: ------------------------------------------------------------------------ This release is numodel-plot only; numodel is version-synced with no functional changes. It is also the first published release carrying the 0.9.0 work: that archive was prepared but never published, so the changes below reach users here. Highlights ---------- * A scaled axis now presents its power of ten as an SI prefix on the unit: "s (km)" instead of "s (10^3 m)", "E (TJ/kg)" instead of "E (10^6 MJ/kg)", "m (Mg)" instead of "m (10^3 kg)". The fold respects unit powers (10^6 m^2 -> km^2) and existing prefixes, and falls back to the power-of-ten form whenever no engineering prefix fits. The new setup key scale-format=exponent restores the previous presentation globally. * New setup key halo-color. The default halo-color=auto matches the tick-label halo to the surrounding background at every \drawplot: a tcolorbox's colback, a beamer colour theme's bg, the pagecolor package's \thepagecolor, and white otherwise. Any other value pins the halo to that colour. Fixed ----- * \qtyPlain produced wrong output on siunitx 3.5.0 and newer. siunitx renamed the variable holding the current prefix-mode from \l_siunitx_quantity_prefix_mode_tl -- a documented public variable through v3.4.14 -- to \l_siunitx_quantity_prefix_mode_str, leaving the old name declared but never assigned. Reading the stale name resolved an empty mode and fell through to plain \qty, so every scaled axis label silently gained a spurious "1": "t (1 ks)" instead of "t (ks)". Nothing errored. The mode is now read from whichever variable carries a value, so both siunitx generations work. Under the hood -------------- * \qtyPlain no longer patches siunitx internals. It is now built entirely on siunitx's documented code-level interface, following the investigation behind siunitx issue #864, which established that the whole prefix-mode pipeline is already public. Axis labels are unchanged; three edge cases the old override got wrong are fixed (a mantissa of 1 behind a sign or comparator is no longer dropped, a number carrying an uncertainty is passed through untouched, and all three prefix-mode values now behave the same whether \qtyPlain is called directly or reached through \edef). * \pzuIfUnitNonEngTF derives its verdict from the net power of ten siunitx extracts from the unit instead of from a hard-coded list of prefix control sequences. Two units change verdict, both towards scaling: \centi\metre\per\centi\second (the prefixes cancel) and \centi\metre\cubed (cm^3 is 10^-6 m^3). Packaging --------- * The bundle now ships one README and one CHANGELOG, both at the bundle root, on CTAN maintainer request. The former per-module README/CHANGELOG pairs have been merged into them; module-specific entries live under a per-module heading within each release. Requirements ------------ * siunitx is now requested with a date of 2023-11-06 (v3.3.8). An older siunitx produces a LaTeX warning rather than an error, but scaled axis labels may come out subtly wrong. See CHANGELOG.md for the full list. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/numodel-bundle The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/latex/numodel-bundle/ ------------------------------------------------------------------------ Thanks for the upload.

Aliocha Skrzypczak submitted the chemidentifier package. Version: 2.0.0 License: lppl1.3c Summary description: Synthesis-order numbering and hyperlinking of chemical compounds Announcement text: -------------------------------------------------------------------------------- chemidentifier -- Logical, synthesis-order numbering and hyperlinking of chemical compounds chemidentifier numbers the compounds of a synthesis-chemistry paper in the logical order of the synthesis -- the order in which they are declared -- rather than the order in which they appear in the text. Every printed number is clickable and jumps to the scheme or paragraph that introduces it. Three commands cover the common case: \chemid* declares, \chemid uses, \chemidhere anchors the link target. Declarations and uses accept comma-separated lists, auto-contracted into ranges (1a-c) or groups (1a,b). A single level of parent/child hierarchy is supported, and \chemidfamily declares a templated family (numbering style, child format, placeholder) applied to every child at once. Written in LaTeX3 (expl3); like \ref/\label, everything settles over two compilations. Works with or without hyperref, on pdflatex, lualatex and xelatex. An optional LuaLaTeX-only helper substitutes compound labels directly inside Inkscape-exported .pdf_tex figures, so a scheme's placeholder text can be replaced with the real, numbered, clickable compound name at compile time.

Furthermore, the `\enfasis` command in the `RetoMatematico` class uses now the `align*` environment instead of `equation*`, which allows for alignment characters inside it, and thus multiline, emphasized equations. Finally, the following macros have been added too: * The inverse hyperbolic trigonometric functions are available via `\arcsinh` and similar. * `\NN`, `\ZZ`, `\QQ`, `\RR`, and `\CC` are added as substitutes to `\N`, `\Z`, `\Q`, `\R`, and `\C`; the latter are now _deprecated_. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/retosmatematicos More information is at https://ctan.org/pkg/retosmatematicos -------------------------------------------------------------------------------- Thanks for the upload.

A high-performance sphere approximation based on Bezier triangles was implemented for the native renderer and ported to AsyGL. A bitmap preview is generated for V3D PDF output so it displays correctly in non-interactive viewers. IBL environment names are now output in the V3D header and IBL fixes were made for Vulkan and AsyGL. A stack overflow with -render=0 was fixed. The Vulkan export now uses tiling with a dynamic viewport and scissor. Rendering issues with pixel() were fixed. Triangle group rendering and a vertex shader bug in the no-lighting path were fixed in the AsyGL library. Threaded renderer crashes on empty scenes and a division by zero were fixed. Surfaces are no longer interpolated as periodic unless they really repeat, and the parametric surface() constructor in graph3 enforces exact endpoint periodicity for periodic splinetypes. A bug in the monotonic splinetype was fixed. The asyinclude function in the slide module now restores currentlight, currentpen, and currentprojection. Documentation and build issues were addressed. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/asymptote More information is at https://ctan.org/pkg/asymptote -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: apxproof
by CTAN Announcements via ctan-ann 27 Aug '26

27 Aug '26

Pierre Senellart submitted an update to the apxproof package. Version: 1.5.0 2026-08-25 License: lppl1.3 Summary description: Proofs in appendix Announcement text: -------------------------------------------------------------------------------- Version 1.5.0 of apxproof adds SyncTeX support. Appendix material and repeated theorems are now typeset from the source files instead of being copied to an auxiliary file, so that editors and PDF viewers point at the source lines that produced them, in the appendix as well as in the main text. This happens by default whenever the engine is run with SyncTeX output enabled; the new "synctex" option forces it on or off. With pdfTeX and XeTeX, the apxproof-synctex script now distributed with the package additionally makes forward search find appendix material. The optional argument that cleveref adds to \label is now supported within repeated material, as are the \zlabel and \zcref commands of zref-clever. A LaTeXML binding, apxproof.sty.ltxml, is now distributed and documented: it converts documents using apxproof to HTML with their proofs deferred, their theorems repeated and their appendix bibliography preserved. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/apxproof More information is at https://ctan.org/pkg/apxproof -------------------------------------------------------------------------------- Thanks for the upload.
