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.

Vaibhav Blayer submitted an update to the tikzphysics package. Version: 1.2.0 2026-09-05 License: lppl1.3c Summary description: TikZ-native shapes and anchors for classical physics diagrams Announcement text: ------------------------------------------------------------------------ tikzphysics 1.2.0 adds reusable per-object defaults, native to[over pulley=P] connections, wedge contact and tangent/normal anchors, and mechanics primitives including supports, pendulums, and motion arrows. The new show anchors, show keys, and physicshelp features provide in-picture discovery of supported keys and anchors. A rewritten manual includes a beginner quickstart, complete systems, and a 31-feature reference. Migration: spring is now a path decoration, used as \draw[spring] (A) -- (B);, instead of a spring node. Spring leads may be zero. Blocks default to 1cm square and pulleys to 1cm diameter. This release also fixes prism centroid and face-midpoint anchors. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/tikzphysics The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/pgf/contrib/tikzphysics/ ------------------------------------------------------------------------ Thanks for the upload.
