Nov 1, 2024November 2024 delivered a focused set of feature work, QA improvements, and release-process hardening for latex3/latex2e. Key features included extending \dospecials to recognize the tab character, updating the l3kernel to 2024-11-02, adding a note on V-type variants and \KeyValue, and enhancing documentation and tests (LTNews 41, #1523 regression test). Additional work included adding support for \={i} in OT1/T1, reworking \MakeTitlecase, and strengthening firstaid with cleveref integration. Release-related fixes cleaned up tag handling and documentation, and a pre-release tagging step was introduced to improve release hygiene. This combination improves stability, typography accuracy, encoding robustness, and time-to-release for users and maintainers.
