by CTAN Announcements 20 Jul '26

20 Jul '26

Udi Fogiel submitted the lua-calendrica package. Version: 0.1 2026-07-19 License: apache2 Summary description: Lua Implementation of Calendrical Calculations by Dershowitz & Reingold Announcement text: ------------------------------------------------------------------------ lua-calendrica is a Lua port of the calendar conversion algorithms from Calendrical Calculations: The Ultimate Edition (4th ed.) by Reingold & Dershowitz. It covers over 20 calendar systems including Gregorian, Julian, Hebrew, Islamic, Chinese, Hindu (traditional and astronomical), Mayan, Persian, Tibetan, Balinese, and more, staying close to the structure of the book's reference implementation. The module is purely computational with no formatting or typesetting functionality, and has no dependencies beyond Lua 5.3 or later. For an example of use with typesetting in LuaTeX, see the upcoming release of polyglossia, where support for Chinese lunisolar calendar will be added. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/lua-calendrica The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/generic/lua-calendrica/ ------------------------------------------------------------------------ Thanks for the upload.

Version: 3.10.3 License: lppl1.3c Summary description: Support for CJK documents in XeLaTeX Announcement text: -------------------------------------------------------------------------------- This release adds new CJK typesetting features, improves punctuation formatting and text decoration alignment, and fixes a bug.

IMPROVEMENTS - Enable adjacent punctuation boundary optimization in full-width format, preserving natural whitespace between a left punctuation mark followed by a right punctuation mark (#975). - Change the width of kaiming-style sentence-ending period from `0.8em` to full-width (#975). - Use `\cleaders` to center underlines relative to the body text, avoiding horizontal offset when the starting position changes (#531). - Use `\xleaders` to align wavy lines relative to the body text while maintaining continuous inter-character connections (#967). - Use `\cleaders` to center double underlines relative to the body text (#967). - Use `\cleaders` to center strikethrough lines relative to the body text (#967). - Use `\cleaders` to center diagonal strikethrough lines relative to the body text (#967). - Use `\cleaders` to center custom lines relative to the body text (#967). BUG FIXES - Detect math nodes in URLs before `\Hy@EndAnnot` ends at top level, and place a trusted Western boundary marker after the link-end whatsit, fixing loss of `CJKecglue` on the right side of `\url` (#972).
