This document provides a summary of significant changes made to the
software between the previous and current versions (see
above). A fully-detailed change summary is provided by the ChangeLog file
included in the release package and by the Git commit history:
Major changes¶
- Build and usage of the library and its utilities requires a C99 capable compiler. 
- New optional codec for the LERC (Limited Error Raster Compression) compression scheme. To have it available, configure libtiff against the SDK available at https://github.com/esri/lerc 
- CMake build: revamp of build scripts 
Software configuration changes¶
- cmake: revamp of the cmake build scripts. There are impacts on the case of some options. 
- cmake: update minimum version and policy version to 3.9. 
- Remove NMake build support. The functionality provided by the NMake build is now completely superseded by the CMake build. 
- Remove antiquated Scons and makefile.lcc build support. 
- Remove non-functional VMS and WinCE support. 
- autogen.shnow updates- config.guessand- config.subfrom master gnulib version.
Library changes¶
- Use of - int8,- uint8,- int16,- uint16,- int32,- uint32,- int64,- uint64typedefs is now deprecated. libtiff code and headers no longer use them, and use their C99 standard equivalents (with- _tsuffix). Those typedefs are still available, with deprecation warnings, but external code is strongly encouraged to use the corresponding C99- stdint.htypes. The deprecated types might be removed in a future release.
- Removal of unused, or now useless due to C99 availability, functions in - port/
- A few issues spotted by static code analysis tools fixed. Compiler warnings addressed. 
Tools changes¶
- In usage text, insert a line of text summarizing each tool's purpose 
- tiff tools: made display of compression methods and their parameters conditional on their actual availability 
- tiff2ps: exit the loop in case of error (#232) 
- tiff2pdf: check that tiff_datasize fits in a signed - tsize_t(#202)
- tiffsplit: exit with - EXIT_FAILUREif there are extra args on the command line
- tiffcmp: fix comparaison with pixels that are fractional number of bytes (#53) 
Contributed software changes¶
- iptcutil.c- set- #ifdef _WIN32(was- #ifdef WIN32, which failed at build time)
