zlib (1:1.2.13.dfsg-1ubuntu4) lunar; urgency=medium
* Add d/p/1390.patch to not update strm.adler for raw streams on s390x
(DFLTCC), otherwise libxml2 gets broken on s390x. LP: #2002511

zlib (1:1.2.13.dfsg-1ubuntu3) lunar; urgency=medium
* Re-add vectorized crc32 support for s390x by adding
d/p/s390x-vectorize-crc32.patch
(crc32vx-v4: s390x: vectorize crc32). (LP: #1998470)
This replaces the previously dropped patch:
lp1932010-ibm-z-add-vectorized-crc32-implementation.patch
* Remove option '--crc32-vx' for s390x in d/rules, that was previously just
commented out, since it's no longer needed with the new s390x crc32 code.
* Update d/p/410.patch to version 26f2c0a4e17e5558d779797d713aa37ebaeef390
due to unused "const char *endptr;".

zlib (1:1.2.13.dfsg-1ubuntu2) lunar; urgency=medium
* Comment out use of --crc32-vx on s390x, since this is currently not
implemented due to the dropped patch that needs porting.

zlib (1:1.2.13.dfsg-1ubuntu1) lunar; urgency=low
* Merge from Debian unstable. Remaining changes:
- Build x32 packages
- debian/zlib-core.symbols: Drop dfsg suffix from version
- Add watch file, with GPG tarball checking, and version mangling
- Cherrypick PR#410 to enable hardware-accelerated deflate.
- Copmile with DFLTCC enabled on s390x.
- Enable hardware compression on s390x at level 6.
- d/rules: use configure options for dfltcc instead of hardcoding
the CFLAGS
* Dropped changes, included upstream:
- Cherry-pick Permit-a-deflateParams-parameter-change-asap.patch
- debian/patches/CVE-2018-25032-2.patch: assure that the number of bits
for deflatePrime() is valid in deflate.c.
* Pull rebased 410.patch from https://github.com/madler/zlib/pull/410.
* Drop d/p/410-lp1961427.patch, included in the above rebase.
* Replace 335.patch for ppc64el (P8) crc32 performance with 478.patch which
supersedes it (https://github.com/madler/zlib/pull/478).
* Forward-port lp1932010-ibm-z-add-vectorized-crc32-implementation.patch.
* Dropped changes:
- d/p/lp1932010-ibm-z-add-vectorized-crc32-implementation.patch: this
patch depends on zlib upstream PR 335 which has been superseded by
upstream PR 478 with significant refactoring. Drop this patch,
pending a port from IBM.
zlib (1:1.2.13.dfsg-1) unstable; urgency=low

to fix s390_crc32_vx() signature mismatch and add '-DS390_CRC32_VX'
also to SFLAGS. LP: #1982583
