+This document describes the changes made to the software between the

+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.

+
+
+Software configuration changes
+------------------------------
+
+* Several fixes in the test suite.
+
+
+Library changes

+* Preliminary support for BigTIFF files: now libtiff can
+ recognize and reject to open such images. ;-)
+
+* :file:`libtiff/tif_dirinfo.c`: changed type of XMLPacket (tag 700) to
+ :c:enumerator:`TIFF_BYTE` instead of :c:enumerator:`TIFF_UNDEFINED` to comply with the info
+ in the Adobe XMP Specification.
+
+* Added many checks for integer overflow and for successful space
+ allocations in the different parts of library. Code review
+ completed by Dmitry V. Levin.
+
+* :file:`libtiff/tiffio.h`, :file:`libtiff/tif_compress.c`: Added
+ :c:func:`TIFFGetConfiguredCODECs` function to get the list of configured codecs.
+
+
+Tools changes
+-------------
+
+* :file:`tiff2bw`: Write ``ImageWidth``/``ImageHeight`` tags to output file, as
+ noted by Gennady Khokhorin.

+* No changes.
+
+
+LZW compression kit changes
