Hello -- I've updated the copy of zlib in Phobos. Here's a reprinting of the big-ticket items from the zlib.net homepage: Version 1.2.12 has these key improvements over 1.2.11: * Fix a deflate bug when using the Z_FIXED strategy that can result in out-of-bound accesses. * Fix a deflate bug when the window is full in deflate_stored(). * Speed up CRC-32 computations by a factor of 1.5 to 3. * Use the hardware CRC-32 instruction on ARMv8 processors. * Speed up crc32_combine() with powers of x tables. * Add crc32_combine_gen() and crc32_combine_op() for fast combines. Due to the bug fixes, any installations of 1.2.11 should be replaced with 1.2.12. Also maintains the fix from here: https://github.com/ibara/phobos/commit/1b6cf80232f19e581f72869a4b339580416dd72d Everything appears OK on my OpenBSD/amd64 machine. But perhaps more testing from others is in order.
