CTAN update: prooftrees
by CTAN Announcements 22 Feb '26

22 Feb '26

Clea F. Rees submitted an update to the prooftrees package. Version: 0.9.3 2026-02-21 License: lppl1.3c Summary description: Forest-based proof trees (symbolic logic) Announcement text: ---------------------------------------------------------------------- prooftrees now uses the updated forest-ext (v0.3) for tagging and memoize-ext for memoizing tagged tableaux (if memoize is loaded). Changes should not affect the user interface unless custom tagging was enabled, in which case some modifications may be required. (But in this case, almost everything is done by the user and not this package, so hopefully this should not be a problem.) This greatly simplifies the memos since most complications involving catcode changes can be avoided. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/prooftrees The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/pgf/contrib/prooftrees/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: forest-ext
by CTAN Announcements 22 Feb '26

22 Feb '26

Clea F. Rees submitted an update to the forest-ext package. Version: 0.3 License: lppl1.3c Summary description: Additional Forest libraries providing bug fixes, extensions and support for tagging Announcement text: -------------------------------------------------------------------------------- Tagging support now provides more concise alt text, but the main change is use of memoize-ext if memoize is loaded in a tagged PDF. This simplifies the memos considerably and provides a more flexible interface in the form of sockets during extern utilisation. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/pgf/contrib/forest-ext More information is at https://ctan.org/pkg/forest-ext -------------------------------------------------------------------------------- Thanks for the upload.

Alain Matthes submitted an update to the tkz-elements package. Version: 5.02c 2026-02-20 License: lppl1.3c Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide Announcement text: ---------------------------------------------------------------------- Added - path Method 'scale' Anisotropic scaling - fct Added half_tangents and tangent methods. Tangents now return unit direction points (no line objects). Fully compatible with set_scale. Unified implementation based on drawing coordinates.

These were incompatible with set_scale and contradicted the Lua-computation / TikZ-drawing design principle. - tkz-elements.sty Deletions and corrections. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/tkz-elements The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-elements/ ------------------------------------------------------------------------ Thanks for the upload.
