SilentDragonPaper/cli/vendor/png/CHANGES.md

0.16.8

• Fixed a bug that led to data corruption when encoding with Average filter.

0.16.7

• Added Encoder::set_trns to register a transparency table to be written.

0.16.6

• Fixed silent integer overflows in buffer size calculation, resulting in panics from assertions and out-of-bounds accesses when actually decoding. This improves the stability of 32-bit and 16-bit targets and make decoding run as stable as on 64-bit.
• Reject invalid color/depth combinations. Some would lead to mismatched output buffer size and panics during decoding.
• Add Clone impl for Info struct.

0.16.5

• Decoding of APNG subframes is now officially supported and specified. Note that dispose ops and positioning in the image need to be done by the caller.
• Added encoding of indexed data.
• Switched to miniz_oxide for decompressing image data, with 30%-50% speedup in common cases and up to 200% in special ones.
• Fix accepting images only with consecutive IDAT chunks, rules out data loss.

0.16.4

• The fdAT frames are no longer inspected when the main image is read. This would previously be the case for non-interlaced images. This would lead to incorrect failure and, e.g. an error of the form "invalid filter method".
• Fix always validating the last IDAT-chunks checksum, was sometimes ignored.
• Prevent encoding color/bit-depth combinations forbidden by the specification.
• The fixes for APNG/fdAT enable further implementation. The next release is expected to officially support APNG.

0.16.3

• Fix encoding with filtering methods Up, Avg, Paeth
• Optimize decoding throughput by up to +30%

0.16.2

• Added method constructing an owned stream encoder.

0.16.1

• Addressed files bloating the packed crate

0.16.0

• Fix a bug compressing images with deflate
• Address use of deprecated error interfaces

0.15.3

• Fix panic while trying to encode empty images. Such images are no longer accepted and error when calling write_header before any data has been written. The specification does not permit empty images.

0.15.2

• Fix EXPAND transformation to leave bit depths above 8 unchanged

0.15.1

• Fix encoding writing invalid chunks. Images written can be corrected: see https://github.com/image-rs/image/issues/1074 for a recovery.
• Fix a panic in bit unpacking with checked arithmetic (e.g. in debug builds)
• Added better fuzzer integration
• Update term, rand dev-dependency
• Note: The show example program requires a newer compiler than 1.34.2 on some targets due to depending on glium. This is not considered a breaking bug.
