## OpenJPEG 2.2.0
No API/ABI break compared to v2.1.2 but additional symbols for
multithreading support (hence the MINOR version bump).
### Codebase improvements
* Memory consumption reduction at decoding side
[\#968](https://github.com/uclouvain/openjpeg/pull/968)
* Multi-threading support at decoding side
[\#786](https://github.com/uclouvain/openjpeg/pull/786)
* Tier-1 speed optimizations (encoder and decoder)
[\#945](https://github.com/uclouvain/openjpeg/pull/945)
* Tier-1 decoder further optimization
[\#783](https://github.com/uclouvain/openjpeg/pull/783)
* Inverse 5x3 DWT speed optimization: single-pass lifting and SSE2/AVX2
implementation [\#957](https://github.com/uclouvain/openjpeg/pull/957)
* Fixed a bug that prevented OpenJPEG to compress losslessly in some
situations [\#949](https://github.com/uclouvain/openjpeg/pull/949)
* Fixed BYPASS/LAZY, RESTART/TERMALL and PTERM mode switches
* Many other bug fixes (including security fixes)
### Maintenance improvements
* Benchmarking scripts to automatically compare the speed of latest
OpenJPEG build with latest release and/or Kakadu binaries
[\#917](https://github.com/uclouvain/openjpeg/pull/917)
* CPU and RAM usage profiling scripts
[\#918](https://github.com/uclouvain/openjpeg/pull/918)
* Codebase reformatting (with astyle) and scripts to automatically check
that new commits comply with formatting guidelines
[\#919](https://github.com/uclouvain/openjpeg/pull/919)
* Register OpenJPEG at Google OSS Fuzz initiative, so as to automatically
have OpenJPEG tested against Google fuzzer
