FYI, from http://www.gzip.org/zlib/:

Version 1.2.1 adds many improvements and features to zlib. Here are some
highlights:

    * inflate is about 20% faster and minimizes memory allocation
    * crc32 is about 50% faster
    * New, improved, and supported DLL interface and DLL FAQ
    * New functions and functionality:
          o deflate() and inflate() will now optionally encode and decode
		gzip streams
          o raw deflate() and inflate() now documented and supported
          o New inflateBack() functions for call-back interface -- faster
		than inflate()
          o Z_BLOCK flush option and new return information added to
		inflate to facilitate appending to deflate streams
          o raw deflate() now accepts a dictionary -- for appending
          o deflatePrime() for starting deflate output mid-byte -- for
		appending
          o Z_RLE strategy for run-length encoding -- option for PNG
		compression
          o gzclearerr() and gzungetc(), analogous to stdio functions
          o inflateCopy() added, analogous to deflateCopy()
          o deflateBound() and compressBound() for maximum size of
		compressed data
          o zlibCompileFlags() to provide compilation information 
    * More supported architectures and improved shared library support
    * Many more FAQ entries
    * Several new and updated contributions in the contrib directory
