This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

Major changes

  • Fixes a number of bugs present in the 3.9.1 release.

  • OJPEG support updated to work with IJG JPEG 7 release.

  • tiffcrop validated for most TIFF storage subformats and sample depths.

Software configuration changes

  • x86_64 now uses the same default fill order as i386.

Library changes

  • Writing tags with an array value of type TIFF_DOUBLE now returns correct error status. The TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE tags failed to write without this fix.
