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:
Software configuration changes¶
- support was added for configuring the Deflate codec 
- support was added for the HTML documentation 
- codecs that are not configured for inclusion in the library are no longer compiled 
Library changes¶
- support was added for registering new codecs external to the library and for overriding the codecs that are builtin to the library 
- emulation support for the old - DataTypetag was improved
- support was added for the - SMinSampleValueand- SMaxSampleValuetags
- the library no longer ignores - TileWidthand- TileLengthtags whose values are not a multiple of 16 (per the spec); this permits old, improperly written, images to be read
- the support for the - Predictortag was placed in a reusable module so that it can be shared by multiple codecs
- experimental compression support was added for the Deflate algorithm (using the freely available zlib package) 
- a new routine, - TIFFWriteBufferSetup()was added à la the routine- TIFFReadBufferSetup()
- the DSO version of the library is now statically linked with the JPEG and Deflate libraries; this means applications that link against the DSO do not also need to link against these ancillary libraries 
Tools changes¶

- tiffdump should now compile on a Macintosh with MPW
