	65f3fc55	2015-06-12 16:11:50		Bug fixes for the brotli encoder. * Fix an out-of-bounds access to depth_histo in the bit cost calculation function. * Change type of distance symbol to uint16_t in block splitter, because if all postfix bits are used, there can be 520 distance symbols. * Save the distance cache between meta-blocks at the correct place. This fixes a roundtrip failure that can occur when there is an uncompressed metablock between two compressed metablocks. * Fix a bug when setting lgwin to 24 in the encoder parameters It ended up making metablocks larger than 24 bits in size. * Fix out-of-bounds memory accesses in parallel encoder. CreateBackwardReferences can read up to 4 bytes past end of input if the end of input is before mask. * Add missing header for memcpy() in port.h

	d6d9fc60	2014-10-15 14:01:36		Factor out serialization functions into their own file. Create a brotli_bit_stream library that is responsible for writing various structures (headers, Huffman codes, etc.) directly into the bit-stream.
	0454ab4e	2014-02-14 15:04:23		Updates to Brotli compression format, decoder and encoder This commit contains a batch of changes that were made to the Brotli compression algorithm in the last month. Most important changes: * Fixes to the spec. * Change of code length code order. * Use a 2-level Huffman lookup table in the decoder. * Faster uncompressed meta-block decoding. * Optimized encoding of the Huffman code. * Detection of UTF-8 input encoding. * UTF-8 based literal cost modeling for improved backward reference selection.

Most important changes: * Updated spec * Changed Huffman code length alphabet to use run length codes more efficiently, based on a suggestion by Robert Obryk * Changed encoding of the number of Huffman code lengths (HLEN) * Changed encoding of the number of Huffman trees (NTREES) * Added support for uncompressed meta-blocks
	c6b9c7c5	2013-11-15 19:02:17		Updates to Brotli compression format, decoder and encoder This commit contains a batch of changes that were made to the Brotli compression algorithm in the last three weeks. Most important changes: * Added UTF8 context model for good text compression. * Simplified context modeling by having only 4 context modes. * Per-block context mode selection. * Faster backward copying and bit reading functions. * More efficient histogram coding. * Streaming support for the decoder and encoder.
