Version 0.18 (2020 February 11)
* Performance enhancements related to decoding of MMR and generic
regions as well as composing images onto pages.
* Bug fixes for a few issues reported by Coverity and OSS-Fuzz.
Version 0.17 (2019 September 16)
* Improved test suite by verifying input file contents and adding
all ubc test streams. Fixed bugs where previously missing ubc
test streams were decoded incorrectly.
* Bug fixes for a few issues reported by Coverity.
* Moved version number to jbig2.h, and adapted configure
correspondingly. Added pkg-config file to be installed
along side library.
Version 0.16 (2019 April 04)
