Check for negative lengths in crc32_combine functions. Copy only the initialized window contents in inflateCopy. Prevent the use of insecure functions without an explicit request. Add compressBound_z and deflateBound_z functions for large values. Use atomics to build inflate fixed tables once. Add --undefined option to ./configure for UBSan checker. Copy only the initialized deflate state in deflateCopy. Zero inflate state on allocation. Add compress_z and uncompress_z functions. Complete rewrite of cmake support. Remove untgz from contrib. Vectorize the CRC-32 calculation on the s390x. Remove vstudio projects in lieu of cmake-generated projects. Add zipAlreadyThere() to minizip zip.c to help avoid duplicates. Add deflateUsed() function to get the used bits in the last byte. Fix bug in inflatePrime() for 16-bit ints. Add a "G" option to force gzip, disabling transparency in gzread(). Return all available uncompressed data on error in gzread.c. Support non-blocking devices in the gz* routines. @ text @d3 1 a3 1 (C) 1995-2026 Jean-loup Gailly and Mark Adler @
