v0.1.18 (2019-12-10)

  • Fix two bugs causing panics introduced in 0.1.17.

v0.1.17 (2019-12-08)

  • Minimum supported rust version changed to 1.34
  • Fix clippy::into_iter_on_array warning
  • Ignore extraneous bytes after SOS
  • Support IDCT Scaling

v0.1.16 (2019-08-25)

  • Minimum supported rust version changed to 1.28
  • Allow zero length DHT segments

v0.1.15 (2018-06-10)

  • Added support for WebAssembly and asm.js (thanks @CryZe!)
  • Bugfix for images with APP14 segments longer than 12 bytes.

v0.1.14 (2018-02-15)

  • Updated rayon to 1.0.

v0.1.13 (2017-06-14)

  • Updated rayon to 0.8.

v0.1.12 (2017-04-07)

  • Fixed an integer overflow in derive_huffman_codes.
  • Updated rayon to 0.7.

v0.1.11 (2017-01-09)

  • Fixed an integer overflow.
  • Updated byteorder to 1.0.

v0.1.10 (2016-12-23)

  • Updated rayon to 0.6

v0.1.9 (2016-12-12)

  • Added a generic integer upsampler, which brings support for some unusual subsampling schemes, e.g. 4:1:1 (thanks @iamrohit7!)
  • Made rayon optional through the rayon cargo feature (thanks @jackpot51!)

v0.1.8 (2016-11-05)

  • Updated rayon to version 0.5.

v0.1.7 (2016-10-04)

  • Added UnsupportedFeature::NonIntegerSubsamplingRatio error
  • Fixed a bug which could cause certain images to fail decoding

  • Avoid allocating coefficients when calling read_info() on progressive JPEGs

v0.1.6 (2016-07-12)

  • Added support for 16-bit quantization tables (even though the JPEG spec explicitly states "An 8-bit DCT-based process shall not use a 16-bit precision quantization table", but since libjpeg allows it there is little choice...)
  • Added support for decoding files with extraneous data (this violates the JPEG spec, but libjpeg allows it)
  • Fixed panic when decoding files without SOF
  • Fixed bug which caused files with certain APP marker segments to fail decoding

  • Performance improvements

v0.1.1 (2016-02-29)

  • Performance improvements

v0.1.0 (2016-02-13)

  • Initial release
