List of changes since previous release from 2018 is quite long:
* Fix crc32.c to compile local functions only if used.
* Check for cc masquerading as gcc or clang in configure.
* Remove destructive aspects of make distclean.
* Separate out address sanitizing from warnings in configure.
* Eliminate use of ULL constants.
* Add fallthrough comments for gcc.
* Clean up minizip to reduce warnings for testing.
* Fix unztell64() in minizip to work past 4GB. (Daniël Hörchner)
* minizip warning fix if MAXU32 already defined. (gvollant)
* Replace black/white with allow/block. (theresa-m)
* Fix indentation in minizip's zip.c.
* Improve portability of contrib/minizip.
* Correct typo in blast.c.
* Change macro name in inflate.c to avoid collision in VxWorks.
* Clarify gz* function interfaces, referring to parameter names.
* Fix error in comment on the polynomial representation of a byte.
* Fix memory leak on error in gzlog.c.
* Avoid adding empty gzip member after gzflush with Z_FINISH.
* Explicitly note that the 32-bit check values are 32 bits.
* Use ARM crc32 instructions if the ARM architecture has them.
* Add use of the ARMv8 crc32 instructions when requested.
* Correct comment in crc32.c.
* Don't bother computing check value after successful inflateSync().
* Use atomic test and set, if available, for dynamic CRC tables.
* Speed up software CRC-32 computation by a factor of 1.5 to 3.
* Add crc32_combine_gen() and crc32_combine_op() for fast combines.
* Add tables for crc32_combine(), to speed it up by a factor of 200.
* Fix the zran.c example to work on a multiple-member gzip file.
* Add gznorm.c example, which normalizes gzip files.
* Show all the codes for the maximum tables size in enough.c.
* Clarify that prefix codes are counted in enough.c.
* Use inline function instead of macro for index in enough.c.
* Clean up code style in enough.c, update version.
* Use a macro for the printf format of big_t in enough.c.
* Use a structure to make globals in enough.c evident.
* Assure that the number of bits for deflatePrime() is valid.
* Fix a bug that can crash deflate on some input when using Z_FIXED.
* Correct the initialization requirements for deflateInit2().
* Emphasize the need to continue decompressing gzip members.
* Add legal disclaimer to README.
* Fix deflateEnd() to not report an error at start of raw deflate.
* Remove old assembler code in which bugs have manifested.
* Make the names in functions declarations identical to definitions.
* Avoid an undefined behavior of memcpy() in _tr_stored_block().
* Avoid undefined behaviors of memcpy() in gz*printf().
* Avoid an undefined behavior of memcpy() in gzappend().
* Avoid the use of ptrdiff_t.
* Handle case where inflateSync used when header never processed.
* Don't compute check value for raw inflate if asked to validate.
* Add address checking in clang to -w option of configure.
* Return an error if the gzputs string length can't fit in an int.
* Small speedup to inflate [psumbera].
* Update use of errno for newer Windows CE versions.
* Avoid some conversion warnings in gzread.c and gzwrite.c.
* Have Makefile return non-zero error code on test failure.
* Avoid a conversion error in gzseek when off_t type too small.
* Fix CLEAR_HASH macro to be usable as a single statement.
* Fix bug when window full in deflate_stored().
* Limit hash table inserts after switch from stored deflate.
* Permit a deflateParams() parameter change as soon as possible.
* Cygwin does not have _wopen(), so do not create gzopen_w() there.
Removed 006-fix-compressor-crash-on-certain-inputs.patch which was
hotfix for CVE-2018-25032 and is now included in this release.
This release is not available on @SF (yet?) so the sources are now
pulled from GitHub.
