John H. Lienhard submitted an update to the
asmeconf
package.
Version: 1.44 2025-11-08
License: mit
Summary description: A LaTeX template for ASME conference papers
Announcement text:
----------------------------------------------------------------------
The asmeconf class is a LaTeX template to format conference papers
published by the American Society of Mechanical Engineers.
This update includes further improvements to PDF accessibility.
Class can produce tagged PDF that validates as UA-2, A-4F, and
WTPDF-1 when run with LuaLaTeX.
A CSS style file has been added to improve rendering in HTML
(e.g., at https://ngpdf.com).
An example of an accessible PDF is included in this distribution.
The most recent version of LaTeX is needed (2025/11/01 or later).
In addition, minor bugs have been fixed, the expl3 code has been
improved, and backward compatibility has been retested.
The minimum supported platform for asmeconf.cls is TeX Live 2022.
Further details are in the README file.

Alain Matthes submitted an update to the
tkz-elements
package.
Version: 4.35c 2025-11-08
License: lppl1.3c
Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
Announcement text:
----------------------------------------------------------------------
This release introduces major internal improvements, new geometric
tools, and the first public integration of Apollonius-related constructions.
Improved geometric engine.
Numerous internal optimisations and structural clean-up of the Lua codebase.
Better consistency between object interfaces (point, line, circle, path, …).
Unified system for solution outputs using paths (path objects storing
centres and through-points).
New or enhanced methods
Robust tests for circle tangency (circle:are_circles_tangents()).
Improved numerical tolerance control (tkz.epsilon, tkz.approx()).
Expanded geometry toolbox: pole of a line w.r.t a circle, inversion-based
utilities, projections, affine transformations.
Apollonius problems – experimental implementation
First complete framework for solving classical Apollonius configurations
(CCC, CCL, CLP, LPP, etc.).
Implementations include Viète reduction, homothety and inversion approaches.
Solutions are returned as paths (pa_center, pa_through) with consistent
structure, ready for TikZ drawing.
Important note on Apollonius methods
The methods related to Apollonius' circle problems are still experimental.
Although many generic cases are already handled (disjoint circles,
external/internal tangencies, equal or unequal radii), the following
must be kept in mind:
Some special or degenerate cases are not yet fully covered, e.g.:
three mutually secant circles,
double contact with equal radii and aligned centres,
combinations of internal/external tangency near inversion singularities.
Corner cases may still produce missing or duplicated solutions.
The code is evolving: names, internal strategies, and outputs may slightly
change in future releases.
These additions are intended as a research and development module,
not yet as a final, guaranteed solver for all configurations.
Documentation & usage
The user manual (doc/tkz-elements.pdf) has been updated accordingly.
A dedicated section on Apollonius problems explains:
Syntax, returned paths, modes ("external", "internal", "all"),
Example TikZ figures using tkz-euclide,
Limitations and known edge cases.
