Fwd: New Windows/others dependencies for bundled GD in PHP 8.6?
Pierre Joye has synchronized PHP's bundled libgd with the libgd 2.4 development codebase as part of work targeting PHP 8.6. The sync adds support for new image format libraries: libjxl (JPEG XL), libultrahdr (Ultra HDR), and libheif (HEIF/HEVC/AV1). Windows builds have been updated in winlibs with working builds for libjxl and libultrahdr, and libheif built with HEVC and AV1 codec support. The main outstanding issue is updating PHP's VS18 dependency manifest so Windows CI can detect and enable these libraries, plus adding them for Ubuntu/Alpine runners. Pierre is asking the internals list for guidance on the proper process to add new packages to the dependency manifest while PHP 8.6 is still in alpha.
