-Subject: [PATCH] NEON implementation for Adler32
-
-The checksum is calculated in the uncompressed PNG data
-and can be made much faster by using SIMD.
-
-Tests in ARMv8 yielded an improvement of about 3x
-(e.g. walltime was 350ms x 125ms for a 4096x4096 bytes
-executed 30 times). That results in at least 18% improvement
-in image decoding in Chromium.
-
-Further details at:
-https://bugs.chromium.org/p/chromium/issues/detail?id=688601

-Subject: [PATCH] Fix a bug when getting a gzip header extra field with
- inflate().
-
-If the extra field was larger than the space the user provided with
-inflateGetHeader(), and if multiple calls of inflate() delivered
-the extra header data, then there could be a buffer overflow of the
-provided space. This commit assures that provided space is not
-exceeded.
