Version 3.2.3 (August 18, 2026)

Patch release with various build and installation fixes. No functional differences.

• Vec integer method resolution improved — Replaced  =delete with SFINAE ("Substitution Failure Is Not An Error"), via a new is_float_like trait, for length(), normalize(), normalizedExc(), etc on integer-typed Vec2/3/4. This gives clearer compiler diagnostics and allows custom numeric types (with an is_float_like specialization) to opt into these methods. half is explicitly supported.

• Fixed duplicate installation of ImathConfig.h

• Fixed shared library installation path

• Fixed Python module install directory, now derived correctly from Python3_SITEARCH instead of a hardcoded/absolute path

• Suppressed a C++23 deprecation warning for std::float_denorm_style/denorm_present usage in numeric_limits<half>

• Simplified CMake minimum-version policy handling by removing explicit CMP0074/CMP0077 settings now implied by the 3.14 minimum

• Documentation fixes: corrected install instructions in README.md, fixed broken links, minor spelling corrections
