Sourced fromgif's changelog.

v0.13.1

Bugfixes:

• Fixed writing palettes with non-power-of-two sizes

v0.13.0

Features:

• AddedIterator interface for theDecoder
• Added reading number of loop repetitionsDecoder::repeat.
• Addedskip_frame_decoding option to readFrame.buffer as LZW data.It works together withwrite_lzw_pre_encoded_frame for quick rewriting of GIF files.
• Added support pre-allocatedVecs infrom_palette_pixels
• Added ability to recover theio::Reader after decoding.
• Added support for decompressingFrame.buffer with LZW data,which enables fully parallel GIF re-encoding (see examples/parallel.rs),

Optimization:

• Less buffering, copying, and lower peak memory usage.

Other changes:

• Removedunsafe {} code.
• Enforced memory limit also on metadata extension blocks, and added out-of-memory checks where possible.
• EncodingFormatError enum is public.
• Removed defunctskip_extensions
• Added validation of frame dimensions. The buffer must be large enough for all pixels,and if the width or height is 0, the buffer must be empty.

v0.12.0

Features:

• Add compression of pre-compressed frame data, viaEncoder::write_lzw_pre_encoded_frame.
• Thecolor_quant dependency is now optional. Turning it off disables someinterfaces that would internally build quantization tables. The genericimplementation of creating such tables can be prohibitively costly comparedto specialized algorithms in some use cases.

Optimization:

• Avoid some allocations in by replacingflat_map argument with arrays

v0.11.4

Bufixes:

• Fix decoding confusing superfluous image data from previous frames withcurrent frame data.
• Bump minimum required version ofweezl.

Features:

• AddEncoder::{get_ref, get_mut, into_inner} to access underlying stream.
