Thu Jan 9 13:00:00 2014
- Update to new upstream release 0.4.0

* improved gif2webp tool

* numerous fixes, compression improvement and speed-up

* dither option added to decoder (dwebp -dither 50 ...)

* improved multi-threaded modes (-mt option)

* improved filtering strength determination

* BMP and TIFF format output added to \'dwebp\'

* Significant memory reduction for decoding lossy images with alpha.

* Intertwined decoding of RGB and alpha for a shorter

* WebPIterator has a new member \'has_alpha\' denoting whether the
frame contains transparency.

* Container spec amended with new \'blending method\' for animation.

Wed Jun 26 14:00:00 2013
- Update to new upstream release 0.3.1

* Add incremental decoding support for images containing
ALPH and ICCP chunks.
- Enable libwebpmux, libwebpdemux

Tue Apr 16 14:00:00 2013
- Update to new upstream release 0.3.0

* WebPINewRGB/WebPINewYUVA accept being passed a NULL output buffer
and will perform auto-allocation.

* Default filter option is now \"-strong -f 60\"

* Encoding speed-up for lossy methods 3 to 6

* Alpha encoding can be done in parallel to lossy using
`cwebp -mt ...`

* Color profile, metadata (XMP/EXIF) and animation support in the
container was finalized.

* Various NEON assembly additions
- Tool updates / additions:

* gif2webp added

* vwebp given color profile & animation support

* cwebp can preserve color profile / metadata with \"-metadata\"

Sun Dec 9 13:00:00 2012
- Update to version 0.2.1

* libwebp: validate chunk size in ParseOptionalChunks

* cwebp (windows): fix alpha image import on XP

* autoconf/libwebp: enable dll builds for mingw

* [cd]webp: always output windows errors

* fix double to float conversion warning

* cwebp: fix jpg encodes on XP

* VP8LAllocateHistogramSet: fix overflow in size calculation

* GetHistoBits: fix integer overflow

* EncodeImageInternal: fix uninitialized free

* fix the -g/O3 discrepancy for 32bit compile

* fix the BITS=8 case

* Make
*InitSSE2() functions be empty on non-SSE2 platform

* make
*InitSSE2() functions be empty on non-SSE2 platform

* make VP8DspInitNEON() public

Fri Aug 31 14:00:00 2012
- Update to version 0.2.0:

* Add support for ARGB -> YUVA conversion for lossless decoder

* Add stats for lossless and alpha encoding

* Security related hardening: allocation and size checks

* Add PAM output support to dwebp

* Alpha channel encode/decode support

* Lossless encoder/decoder

* Add TIFF input support to cwebp

* Incompatible changes:
- The encode ABI has been modified to support alpha encoding
- Deprecated function WebPINew() has been removed
- Decode function signatures have changed to consistently use
size_t over int/uint32_t
- decode_vp8.h is no longer installed system-wide
- cwebp will encode the alpha channel if present.

* Add libtiff-devel BuildRequires for the new tiff input support.

* Rename libwebp2 subpackage to libwebp4 (by changing lname
defines), following upstreams soname bump (incl. baselibs.conf).

* No reason to run autogen

Mon Jan 30 13:00:00 2012
- Rename webp-tools to libwebp-tools to follow scheme of other
*-tools packages.

Wed Nov 23 13:00:00 2011
- add libtool as buildrequire to avoid implicit dependency

Mon Oct 31 13:00:00 2011
- update to 0.1.3:

* Advanced decoding APIs.

* On-the-fly cropping and rescaling of images.

* SSE2 instructions for decoding performance optimizations on x86 based platforms.

* Support Multi-threaded decoding.

* 40% improvement in Decoding performance.

* Add support for RGB565, RGBA4444 & ARGB image colorspace.

* Better handling of large picture encoding.

Fri Sep 16 14:00:00 2011
- add baselibs.conf and use original tar

Sat Aug 6 14:00:00 2011
- Rename subpackage libwebp-tools to webp-tools to get out of
rpmlint\'s pedant observation that it does not contain libraries.
