To enable it, set the Lua option `stop_after = "flow analysis"` > either in your Lua code or your configuration file. > > After this change, you may already see preliminary flow analysis results in > explcheck's verbose output. However, unless explcheck understands your file > sufficiently well, it will typically stop before reaching the flow analysis > step and will report this in the verbose output. > > If explcheck reaches semantic analysis, you can encourage it to proceed to > flow analysis by decreasing the Lua option `min_code_coverage` towards zero. > If explcheck bails out earlier, try disabling `stop_early_when_confused` or, > ideally, improve your code quality and contribute to expltools so that it can > understand your code better. 😉 > > - In the syntactic analysis, fix the assignment of segment numbers to `T`- and > `F`-type arguments.

(contributed by @dependabot in #153) > > - Bump actions/upload-artifact from 5 to 6. (contributed by @dependabot in #154) > > - Display processing progress in the CI.

Alain Matthes submitted an update to the tkz-elements package. Version: 4.50c 2026-01-25 License: lppl1.3c Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide Announcement text: ---------------------------------------------------------------------- New in version 4.50c Introduction of the angle class (experimental), providing a dedicated object for oriented and non-oriented angles. Introduction of the list_point class (experimental), a container for ordered collections of points. Improvements and fixes across core classes (circle, line, point, quadrilateral, conic). New matrix algorithms (gauss_jordan, rank) and rewritten triangle angle handling. Ongoing documentation restructuring, with systematic tables of attributes and methods, cross-referenced throughout the manual. The new classes angle and list_point are marked as experimental: their interfaces are stable enough for use, but they are not yet fully integrated into all parts of the ecosystem. ---------------------------------------------------------------------- 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.
