Liam Huang submitted an update to the CTeX bundle. Version: 2.6.0 2026-06-23 License: lppl1.3c Summary description: LaTeX classes and packages for Chinese typesetting Announcement text:

ctex v2.6.0 is a major release that synchronises the bundle with recent LaTeX2e and expl3 baselines and addresses long-standing issues across heading, font, and engine-adaptation subsystems. NEW FEATURES * New experimental option experiment/font-size-system selecting between word, letterpress (was traditional) and user-defined Chinese font-size tables (#543, #813). * Document clarifies that "letterpress" denotes one specific metal-type font-size system rather than the only traditional one (#871). * pdfLaTeX with UTF-8 input now prefers the \DeclareUnicodeCharacter definition for four-byte UTF-8 characters (#815). * Document fonts unified to the Noto CJK family (#686). BUG FIXES * hyperref driverfallback is now handled per loading state to avoid duplicate-setting warnings (#715). * The \verb / \do@noligs xkanjiskip leak under upLaTeX is fixed by porting the lltjcore patch (#556). * pifont's interchartokenstate no longer leaks into the output routine via a vertical-mode page break (#688). * Heading documentation explains the interaction between the runin and aftertitle options (#574). * Fixed corrupt argument signature \@@_char_auxi:NNNN (was NNN). * CJKpunct override of CJKglue in the preamble now works for all engines via the engine-deferred redefinition pattern (#761). BREAKING CHANGES * \newCJKfontfamily defines its font-switching command locally instead of globally (#751/PR #773), aligning with \newcommand semantics inside groups. * Removed compatibility shims for LaTeX2e older than 2020/10/01 (#746). * Minimum LaTeX3 (expl3) baseline raised to 2025/10/09. DEPRECATIONS * Replaced deprecated _tl keys with \l_keys_key_str and \l_keys_choice_str (#806). * Replaced deprecated \char_to_utfviii_bytes:n. Full ChangeLog (per \changes{v2.6.0} entries) is in the package documentation. Source and issue tracker: https://github.com/CTeX-org/ctex-kit
