Functional Changes
Show memory usage. HC_Show_Memory_Usage(long* allocated, long* in_use) has changed input parameter type from long to size_t in order to reliably return the correct value on Windows platform. The function signature is changed to HC_Show_Memory_Usage(size_t* allocated, size_t* in_use).
Screen extents computation. When any computation of screen extents is called, and no geometry is found without the screen extents, an invalid rectangle (instead of full window extents) will be returned.
Selection. Pruned geometry is not selectable.
Freetype upgrade. Upgraded Freetype v2.13.2 to address critical vulnerabilities and exposures.
Harfbuzz upgrade. Upgraded Harfbuzz v2.9.1 to address critical vulnerabilities and exposures.
libtiff upgrade. Upgraded libtiff to v4.6 to address critical vulnerabilities and exposures.
zlib upgrade. Upgraded zlib to v1.3 to address critical vulnerabilities and exposures.
