v0.9.0

Added

• encoder API: add JxlEncoderSetExtraChannelDistance to adjust the quality
  of extra channels (like alpha) separately.
• encoder API: new api functions for streaming encoding:
• JxlEncoderSetOutputProcessor
• JxlEncoderFlushInput
• JxlEncoderOutputProcessor struct
• JxlEncoderSetOutputCallback
• JxlChunkedFrameInputSource struct
• JxlEncoderAddChunkedFrame
• encoder API: new options for more fine-grained control over metadata
  preservation when using JxlEncoderAddJPEGFrame:
• JXL_ENC_FRAME_SETTING_JPEG_KEEP_EXIF
• JXL_ENC_FRAME_SETTING_JPEG_KEEP_XMP
• JXL_ENC_FRAME_SETTING_JPEG_KEEP_JUMBF
• encoder API: new function JxlEncoderSetUpsamplingMode to change the upsampling
  method, e.g. to use nearest-neighbor upsampling for pixel art
• decoder API: implemented JxlDecoderSetOutputColorProfile and
  JxlDecoderSetCms to enable decoding to desired colorspace.
• cjxl can now be used to explicitly add/update/strip Exif/XMP/JUMBF metadata using
  the decoder-hints syntax, e.g. cjxl input.ppm -x exif=input.exif output.jxl
• djxl can now be used to extract Exif/XMP/JUMBF metadata
• encoder API: new function JxlEncoderDistanceFromQuality for convenience to
  calculate a distance given a quality

Removed

• API: the Butteraugli API (jxl/butteraugli.h) was removed.
• encoder and decoder API: all deprecated functions were removed:
  JxlDecoderDefaultPixelFormat, JxlEncoderOptionsSetLossless,
  JxlEncoderOptionsSetEffort, JxlEncoderOptionsSetDecodingSpeed,
  JxlEncoderOptionsSetDistance, JxlEncoderOptionsCreate, as well as
  the deprecated enumerator values JXL_DEC_EXTENSIONS, JXL_ENC_NOT_SUPPORTED,
  JXL_TYPE_BOOLEAN, JXL_TYPE_UINT32, and deprecated type JxlEncoderOptions.
• decoder API: the signature of JxlDecoderGetColorAsEncodedProfile,
  JxlDecoderGetICCProfileSize, and JxlDecoderGetColorAsICCProfile
  changed: a deprecated unused argument was removed.

Changed / clarified

• changed the name of the cjxl flag photon_noise to photon_noise_iso
• fixed how large boxes are decoded (#2958)
• fixed encoding files with unreadable patches (#3042, #3046)

Note: This release is for evaluation purposes and may contain bugs, including security bugs, that may not be individually documented when fixed. See the SECURITY.md file for details. Always prefer to use the latest release.

v0.8.2

Changed

• Security: Fix an integer underflow bug in patch decoding (#2551- CVE-2023-35790).

Note: This release is for evaluation purposes and may contain bugs, including security bugs, that may not be individually documented when fixed. See the SECURITY.md file for details. Always prefer to use the latest release.

v0.8.1

Changed

• Allow fast-lossless for 16-bit float input (#2093)
• Fix bug in palette (#2120)
• Security: Fix OOB read in exif.h (#2101 - CVE-2023-0645)

v0.8.0

Added

• decoder API: new function JxlDecoderSetImageBitDepth to set the bit depth
  of the output buffer.
• decoder API proposal: add JxlDecoderSetOutputColorProfile and
  JxlDecoderSetCms to enable decoding to desired colorspace; NB: not
  implemented yet.
• encoder API: new function JxlEncoderSetFrameBitDepth to set the bit depth
  of the input buffer.
• encoder API: add an effort 10 option for lossless compression; using this
  setting requires calling JxlEncoderAllowExpertOptions.
• encoder API: new JXL_ENC_FRAME_SETTING_JPEG_COMPRESS_BOXES enum value to
  allow explicit control of metadata compression

Removed

• common API: removed JxlIntrinsicSizeHeader
• decoder API: removed deprecated JXL_DEC_NEED_DC_OUT_BUFFER and
  JXL_DEC_DC_IMAGE events, JxlDecoderDCOutBufferSize and
  JxlDecoderSetDCOutBuffer functions

Changed / clarified

• encoder API: JxlEncoderProcessOutput requires at least 32 bytes of output
  space to proceed and guarantees that at least one byte will be written

Note: This release is for evaluation purposes and may contain bugs, including security bugs, that may not be individually documented when fixed. See the SECURITY.md file for details. Always prefer to use the latest release.
