- update to 2.2.3: * This time we have two code fixes for potentially unsafe access, although we have not had any bug-reports about these. * It also contains several optimizations. Especially of note, inflate has been optimized on various instruction sets and also the generic C code has seen improvements, and we have improvements for arches where unaligned accesses are not possible (lacking instructions to handle unaligned access) and also improvements on big endian. * x86-64 AVX2: Inflate ~17.8% faster, Deflate unchanged. -4.6KB library size. * Aarch64: Inflate ~2.3% faster, Deflate unchanged. - 5.5KB library size. * We also took some time to do a comprehensive cleanup of the now misleading UNALIGNED_OK option and of all the "unaligned" functions. We have noticed that some distros have been disabling these, fearing they are using potentially unsafe unaligned pointers, but we already fixed that in 2.1.0-beta1. Since then, these "unaligned" settings/functions have been referring to using unaligned accesses in safe ways, like utilizing unaligned intrinsics or memcpy to fix alignment for example and selecting what safe method is optimal to the arch. So disabling that instead disabled several safe optimizations. * Because this was obviously misleading certain distros into disabling these optimizations, we have cleaned it up, removed a lot of unnecessary preprocessor checks, and made detection of optimal methods happen during compile instead of configure. As a bonus, this cleaned up a lot of code and also let us not compile in many extra variants of

- Install the ld.so configuration file also with the -32bit package, as otherwise biarch installs won't find that library (boo#1232065).
