+## Unreleased
+
+## 0.17.10
+
+* Added Transformations::ALPHA
+* Enable encoding pixel dimensions
+
+## 0.17.9
+
+* Fixed a bug in ICC profile decompression.
+* Improved unfilter performance.
+
+## 0.17.8
+
+* Increased MSRV to 1.57.0.
+* Substantially optimized encoding and decoding:
+ - Autovectorize filtering and unfiltering.
+ - Make the "fast" compression preset use fdeflate.
+ - Switch decompression to always use fdeflate.
+ - Updated to miniz_oxide 0.7.
+ - Added an option to ignore checksums.
+* Added corpus-bench example which measures the compression ratio and time to
+ re-encode and subsequently decode a corpus of images.
+* More fuzz testing.
+
+## 0.17.7
+
+* Fixed handling broken tRNS chunk.
+* Updated to miniz_oxide 0.6.
+
+## 0.17.6
+
+* Added `Decoder::read_header_info` to query the information contained in the
+ PNG header.
+* Switched to using the flate2 crate for encoding.
+
+## 0.17.5
+
+* Fixed a regression, introduced by chunk validation, that made the decoder
+ sensitive to the order of `gAMA`, `cHRM`, and `sRGB` chunks.
+
+## 0.17.4
+
+* Added `{Decoder,StreamDecoder}::set_ignore_text_chunk` to disable decoding of
+ ancillary text chunks during the decoding process (chunks decoded by default).
+* Added duplicate chunk checks. The decoder now enforces that standard chunks
+ such as palette, gamma, … occur at most once as specified.
+* Added `#[forbid(unsafe_code)]` again. This may come at a minor performance
+ cost when decoding ASCII text for now.
+* Fixed a bug where decoding of large chunks (>32kB) failed to produce the
+ correct result, or fail the image decoding. As new chunk types are decoded
+ this introduced regressions relative to previous versions.
+
+## 0.17.3
+
+* Fixed a bug where `Writer::finish` would not drop the underlying writer. This
+ would fail to flush and leak memory when using a buffered file writers.
+* Calling `Writer::finish` will now eagerly flush the underlying writer,
+ returning any error that this operation may result in.
+* Errors in inflate are now diagnosed with more details.
+* The color and depth combination is now checked in stream decoder.
+
+## 0.17.2
+
+* Added support for encoding and decoding tEXt/zTXt/iTXt chunks.
+* Added `Encoder::validate_sequence` to enable validation of the written frame
+ sequence, that is, if the number of written images is consistent with the
+ animation state.
+* Validation is now off by default. The basis of the new validation had been
+ introduced in 0.17 but this fixes some cases where this validation was too
+ aggressive compared to previous versions.
+* Added `Writer::finish` to fully check the write of the end of an image
+ instead of silently ignoring potential errors in `Drop`.
+* The `Writer::write_chunk` method now validates that the computed chunk length
+ does not overflow the limit set by PNG.
+* Fix an issue where the library would panic or even abort the process when
+ `flush` or `write` of an underlying writer panicked, or in some other uses of
+ `StreamWriter`.
+
+## 0.17.1
+
+* Fix panic in adaptive filter method `sum_buffer`
+
+## 0.17.0
+
+* Increased MSRV to 1.46.0
+* Rework output info usage
+* Implement APNG encoding
+* Improve ergonomics of encoder set_palette and set_trns methods
+* Make Info struct non-exhaustive
+* Make encoder a core feature
+* Default Transformations to Identity
+* Add Adaptive filtering method for encoding
+* Fix SCREAM_CASE on ColorType variants
+* Forbid unsafe code
+
+## 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.
