- Update to version 3.0.4 * Fixed an issue whereby the CPU usage of the default marker processor in the decompressor grew exponentially with the number of markers. This caused an unreasonable slow-down in `jpeg_read_header()` if an application called `jpeg_save_markers()` to save markers of a particular type and then attempted to decompress a JPEG image containing an excessive number of markers of that type. * Hardened the default marker processor in the decompressor to guard against an issue (exposed by 3.0 beta2[6]) whereby attempting to decompress a specially-crafted malformed JPEG image (specifically an image with a complete 12-bit-per-sample Start Of Frame segment followed by an incomplete 8-bit-per-sample Start Of Frame segment) using buffered-image mode and input prefetching caused a segfault if the `fill_input_buffer()` method in the calling application's custom source manager incorrectly returned `FALSE` in response to a prematurely-terminated JPEG data stream. * Fixed an issue in cjpeg whereby, when generating a 12-bit-per-sample or 16-bit-per-sample lossless JPEG image, specifying a point transform value greater than 7 resulted in an error ("Invalid progressive/lossless parameters") unless the `-precision` option was specified before the `-lossless` option. * Fixed a regression introduced by 3.0.3[3] that made it impossible for calling applications to generate 12-bit-per-sample arithmetic-coded lossy JPEG images using the TurboJPEG API. * Fixed an error ("Destination buffer is not large enough") that occurred when attempting to generate a full-color lossless JPEG image using the TurboJPEG Java API's `byte[] TJCompressor.compress()` method if the value of `TJ.PARAM_SUBSAMP` was not `TJ.SAMP_444`.
