20250808

Distribution changes

• On Mac/Linux, libtcl, libtk, and _tkinter are built as separate shared objects, which fixes matplotlib's tkagg backend (the default on Linux), Pillow's PIL.ImageTk library, and other extension modules that need to use libtcl/libtk directly. Note that this change also stops shipping Tix, a deprecated Tk extension that was previously shipped for Linux (but not Mac) but seemingly was broken. (#676)

Build system changes

• The "ci:" labels on PRs, to limit which CI targets are built, now take effect again. (#731)
• Various other fixes to the release workflow.

20250712

Distribution changes

• Restore the SQLite "fts4", "fts5", "rtree", and "geopoly" extensions on Mac/Linux platforms, and add regression tests. These were unintentionally dropped in an upgrade, likely due to SQLite changing their build system and its default configuration. (#694)

Build system changes

• Fix local (non-CI) builds which were failing due to a missing Makefile dependency (#692)

(Please note the release process for the 20250711 tag failed in CI. I have left the Git tag alone for the sake of downstream systems that might have picked it up automatically, but I have deleted the GitHub release and you should not use the tag/release.)
