New comparison helper: tkz.approx (optional EPS). class line: Aliases perpendicular_bisector and bisector for mediator. New method harmonic with mode "internal", "external" or "both". class triangle: isodynamic_points (alias neuberg_points). three_apollonius_circles. apollonius_circle. apollonius_points. apollonius_circles. Changed class matrice: Fixes for print_matrix and matrix:print. Correction of method htm. Intersection Complete rewrite of algorithms with a unified EPS parameter for precision control. class circle: Many methods now accept an optional EPS argument: on_circle, in_out, in_disk, in_out_disk, in_disk_strict, out_disk_strict, in_out_disk_strict, line_position, pole, is_tangent, is_secant, circles_position, orthogonal_through, midcircle, common_tangent. Improved behaviour of CLL for parallel lines. class line Improved LLL. Documentation: Some corrections New Gothic example for CLP. New CLL example with parallel lines. Rewrite of search_circle.lua. Expanded Apollonius section with new CLP examples.

New on CTAN: freemath
by CTAN Announcements 23 Nov '25

23 Nov '25

Plante submitted the freemath package. Version: 1.0 License: lppl1.3c Summary description: LaTeX maths without backslashes Announcement text: ---------------------------------------------------------------------- The freemath package allows for the omission of backslashes from most math mode commands. Specifically, any consecutive string of at least two (Latin) letters appearing in math will automatically be turned into the control sequence with the same name, if it exists. The package provides the `\freemathon` and `\freemathoff` commands which respectively activate and deactivate this behaviour. It is disabled by default upon loading. Regular commands initiated by a backslash may of course still be used when freemath is active, and can furthermore be freely mixed with backslash-free commands. Example: With freemath: `lim_{n to infty} int_Omega n log left( 1 + frac{f}{n} right) d mu`. Without freemath: `\lim_{n \to \infty} \int_\Omega n \log\left( 1 + \frac{f}{n} ) d\mu`. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/freemath The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/freemath/ ------------------------------------------------------------------------ Thanks for the upload.

Jonathan P. Spratte submitted an update to the ducksay package. Version: 2.8 2025-11-22 License: lppl1.3c Summary description: Draw ASCII art of animals saying a specified message Announcement text: ---------------------------------------------------------------------- This release fixes two bugs which were introduced by changes in the kernel in 2025-06-01 and 2025-11-01. - `tail-symbol` wasn’t using the correct category codes if the symbol was a letter since `ltcmd`’s `v`-type no longer sets all category codes to 12. - `\AddColoredAnimal` wasn’t working due to the same reason and the used regular expression being too restrictive. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/ducksay The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/ducksay/ ------------------------------------------------------------------------ Thanks for the upload.
