@Dead2 Dead2 released this 10 Jan 22:35
2.1.6
7425372

This is a stable release, with several minor improvements and one corruption fix for inflateCopy().
This release also improves on the functable implementation, and also moves its initialization to happen in deflateInit() and inflateInit(). We also have some optimizations for RVV and ARM.

Notes for packagers:

  • FAR macro has been added back to zlib-compat mode in this release, please remember to remove downstream patches that add it.
  • Please consider removing CMake INSTALL_LIB_DIR workarounds, this should not be needed since v2.0.2 (2021), but packagers seem to keep copying the workaround from each other. Please see cmake/detect-install-dirs.cmake.
