v3.1.12

Patch release with a small fix:

• Support for compiling half.h with hip-runtime-amd

Also, the v3.1.11 release had improper versioning in its cmake and pkgconf configuration files. This is now fixed.

v3.1.11

Patch release with small build fix:

• Add explicit std:: namespace for isfinite in ImathFun.cpp

This release also introduces the practice of signing release artifacts via sigstore.

v3.1.10

Patch release with various build/bug fixes.

Build fixes:

• Fix a problem where downstream projects using Imath would build python bindings even if they weren't requested.
• Fix for missing std::bit_cast
• Fix missing/necessary use of IMATH_HOSTDEVICE
• IMATH_INSTALL_PKG_CONFIG is now on by default, even on Windows
• Fix calling default constructor by uniform init in TypeTraits
• Fix redundant PYIMATH_EXPORTS causing compile issues on Windows Clang

Bug fixes:

• Fix half to float giving wrong results on older x86_64 CPUs on Windows

Other changes:

• succ()/pred() now use std::nextafter().
• Expand epsilon bounds for m44x pyImath test.
• Rename "docs" to "website".
• Add missing copyright/license identifiers.

v3.1.9

Patch release that fixes an correct .so version number introduced in v3.1.8. All Imath library functionality is compatible with v3.1.8.

This release also reverts #305, which inadvertently introduced additional python bindings in v3.1.8 that altered the ABI of libPyImath. libPyImath is now ABI-compatible with v3.1.7 and previous releases.

v3.1.8

Patch release that addresses miscellaneous minor compiler/build/doc issues and extends test coverage, including:

#317 fix the macro switching half-precision floating-point format implementation.
#314 Remove duplicate IMATH_HOSTDEVICE
#313 IMATH_EXPORT for Rand32::nextf()

See CHANGES.md for complete details.

v3.1.7

Patch release with miscellaneous bug/doc/build fixes. In particular:

• Support for relative prefix in pkg-config
• Reorganization of documentation at https://imath.readthedocs.io
• The CMake config for building the docs is now BUILD_DOCS instead of DOCS
• Add a trace() method on Matrix types

See CHANGES.md for more details.
