Release Notes
---------------

v0.8.0
^^^^^^^

- Tegra/Jetson support added.
- Python wheels for installing nvJPEG2000 library through pip.
- Decoder

   * Decoder supports interleaved output format. Can be enabled using :code:`nvjpeg2kDecodeParamsSetOutputFormat`.
   * New API (:code:`nvjpeg2kStreamParseFile`) which accepts file name as input has been added.
   * Number of layers that can be decoded increased from 20 to 32.
   * Bitstreams with COC marker can be decoded as long as the parameters are same across all components.
   * Fixed a bug which could cause the decoder to crash when multiple tiles and custom precincts are enabled with RPCL, PCRL, CPRL pogression orders.

- Encoder

   * Custom precincts are supported. Set :code:`num_precincts_init` (part of :code:`nvjpeg2kEncodeConfig_t`)to valid no of precincts in :code:`precinct_width`, and :code:`precinct_height`.
   * Encoder accepts images in interleaved format. Can be enabled using :code:`nvjpeg2kEncodeParamsSetInputFormat`.

- Support for Centos/RHEL 7 is deprecated and will be dropped in future releases.

- **Breaking Changes**

   * The following fields in :code:`nvjpeg2kEncodeConfig_t` have been renamed -

      * :code:`precint_width` renamed to :code:`precinct_width` to fix typo.
      * :code:`precint_height` renamed to :code:`precinct_height` to fix typo.
      * :code:`enable_custom_precincts` renamed to :code:`num_precincts_init` to better reflect the behavior.

v0.7.5
^^^^^^^
- This release provides important security updates for CVE-2023-31027 and is recommended for all users.

   * To view any published security bulletins for NVIDIA products, see the NVIDIA product security page (https://www.nvidia.com/en-us/security/). 
   * For more information regarding NVIDIA's security vulnerability remediation policies, see (https://www.nvidia.com/en-us/security/psirt-policies/)

- Arm sbsa support added.
- Inverse wavelet transform optimizations. Up to 20% improvement in single image decode throughput observed for RGB HTJ2K bitstreams.
- Bitstreams with QCC marker can now be decoded.
- Bitstreams with COM marker in the tile header can now be decoded.

v0.7.0
^^^^^^^

- High throughput JPEG 2000 code streams can now be decoded. All code-blocks have to be HT code-blocks with one HT set and no refinement.
- CUDA 12 support - Binaries for both CUDA 11 and CUDA 12 are available.
- Extended allocator support which accepts cuda streams and context information.
- Memory Padding APIs for both pinned and device memory have been added.
- Fixed multiple issues which were causing the decoder to hang or crash.
- Fixed an issue which was causing the encoder to error out when compressing random data.

v0.6.0
^^^^^^^
- Decoder

   * 4k digital cinema profile support.
   * JPEG 2000 bitstreams with predictable termination enabled can be decoded.
   * Hopper(sm90) support is added.
   * Fixed an issue in the quantization information parser. This was causing decode output corruption in some cases.
   * Fixed a horizontal clipping issue seen with :code:`nvjpeg2kDecodeImage()`, when an area of interest was decoded.

- Encoder

   * Fixed an issue which was resulting in wrong output when no of components = 4 and mct mode was enabled.
  

v0.5.0
^^^^^^^
- Decoder

   * JPEG 2000 bitstreams with last partition length set to 0 can be decoded.
   * JPEG 2000 bitstreams with cdef jp2 header can be decoded.
   * Bitstream corruption checks have been relaxed.
- Encoder

   * Multi-tile encoding.
   * All progression orders are supported.
   * Performance improvements for lossy encoding.

v0.4.0
^^^^^^^
- JPEG2000 encode support added. See :ref:`nvjpeg2kintroencoder-label` for details.
- Encode/Decode support added for 420/422 formats with alpha channel (yuva420p).
- nvJPEG2000 is now available on WSL-Ubuntu.

v0.3.0
^^^^^^^
- Bitstreams with 422 and 420 chroma sub-sampling are supported.
- RGB output support for images with 420 and 444 chroma sub-sampling.
- New nvjpeg2kDecodeImage API added.
- Inverse discrete wavelet transform performance improvements.


v0.2.0
^^^^^^^
- New API added for Tile/Resolution based decode.
- Tiles can be partially decoded by specifying an area of interest.
- Tiles with multiple partitions are supported.
- All progression orders are supported.
- Bitstreams with up to 20 layers can be decoded.


v0.1.0
^^^^^^^
- nvJPEG2000 is now available on Microsoft Windows 10 and Windows Server 2019.
- Bitstreams with multiple tiles are now supported. Each tile can have a single tile partition.
- RLCP progression order is supported.
- Fixed an intermittent issue which was causing the library to produce incorrect decode output.
