Changes: A problem in the new memory source manager with corrupt JPEG data has been resolved. An issue in the Makefile.am test target was fixed. MinGW installation is now supported with automatic configuration.

Changes: New data source and destination managers, jpeg_mem_src() and jpeg_mem_dest(), were added to the API. The accuracy of floating point IDCT calculations was improved. jpegtran now supports the same "-scale" option as djpeg for "lossless" resize. Support for 32-bit BPMs (RGB images with an alpha channel) was added. A potential crash in the BMP reader module was fixed.

Changes: New scaled DCTs were implemented. New API functions were added. Support for arithmetic entropy encoding and decoding was added. The support programs gained several new options, such as a new "lossless" cropping feature for jpegtran.
