+# Version 0.9.0
+
+New features:
+* Added support for photometric interpretation `YCbCr` and added related
+  `ColorType`.
+
+Fixes:
+* Decoding tiled images calculates padding correctly when image width or height
+  is a multiple of tile size. It could previously corrupt the last tile per row
+  by skipping over data.
+
+# Version 0.8.1
+
+Changes:
+* The jpeg decoder gained to ability to utilize the Photometric Interpretation
+  directly instead of relying on a custom APP segment.
+
+Fixes:
+* A spurious error within the PackBits decoder lead to the incorrect results
+  (wrong bits or errors), based on the maximum size of reads from the
+  underlying reader.
+* Removed a panic path in jpeg decoding, when a feature such as photometric
+  interpretation is not supported. An error is returned instead.
+
+# Version 0.8.0
+
+Changes:
+* The minimum supported rust version is now indicated in `Cargo.toml`.
+* The enums `TiffFormatError` and `TiffUnsupportedError` are now
+  marked with the `#[non_exhaustive]` attribute. 
+* Additionally, tag related enums `Value`, `Tags`, `Type`, `CompressionMethod`,
+  `PhotometricInterpretation`, `PlanarConfiguration`, `Predictor`,
+  `ResolutionUnit`, `SampleFormat` are also changed.
+
+Removals:
+* Removed deprecated methods of `Decoder`: `init`, `read_jpeg`,
+  `read_strip_to_buffer`, `read_strip`, `read_tile`. The implicit chunk (row or
+  tile) index order could not be easily tracked by the caller. New separate
+  utility interfaces may be introduced at a later point, for now callers are
+  obligated to choose their own.
+
+Fixes:
+* Update to `jpeg_decoder = 0.3`.
+
+# Version 0.7.4
+
+New features:
+* Creating an encoder for invalid, zero-sized images is now rejected.
+
+Fixes:
+* Fix panic, in a case where decoding jpeg encoded images did not expect the
+  jpeg decoder to return an error.
+* Fix panic by validating `rows_per_strip` better, fixing a division-by-zero.
+
+# Version 0.7.3
+
+New features:
+* Allow decoder to access specific tiles by index.
+* Add support for floating point predictor.
+* Tiled jpeg file support.
+
+Changes:
+* Various refactoring and performance improvements.
+
+# Version 0.7.2
+
+New features:
+* Encoding with `ImageEncoder` now takes an optional compressor argument,
+  allowing compressed encoding. See the methods 
+  `TiffEncoder::{new_image,write_image}_with_compression`.
+* `jpeg_decoder` has been upgraded, now supports lossless JPEG.
+
+Changes:
+* Decoding now more consistently reads and interprets the initial IFD, instead
+  of performing _some_ interpretation lazily. (This change prepares fully lazy
+  and backwards seeking.)
+
+# Version 0.7.1
+
+New features:
+* Encoding signed integer formats is now supported.
+* Extensive fuzzing with `cargo fuzz`.
+
+Changes:
+* Tile decoding should be a little faster, requires one less intermediate buffer.
+* Images whose IFDs form a cycle due to their offsets will now raise an error
+  when the cycle would be entered (jumping back should still be supported).
+
+Fixes:
+* Fixed a regression that caused conflict between strips and tile images,
+  causing errors in decoding some images.
+* Use checked integer arithmetic in limit calculations, fixes overflows.
+* IFD Tags are now always cleared between images.
+* Found by fuzzing: Several memory limit overflows; JPEG now correctly
+  validates offsets and a minimum size of its table; Check upper limit of strip
+  byte size correctly;
+
+Notes:
+Our CI has warned that this version no longer builds on `1.34.2` out of the
+box. We're still committed to the MSRV on this major version yet one
+dependency—`flate2`—has already bumped it in a SemVer compatible version of its
+own. This is out-of-our-control (cargo's dependency resolution does not allow
+us to address this in a reasonable manner).
+
+This can be address this by pinning the version of `flate2` to `1.0.21` in your
+own files. However, you should understand that this puts you in considerable
+maintenance debt as you will no longer receive any updates for this dependency
+and any package that _requires_ a new version of the `1.0` series would be
+incompatible with this requirement (cargo might yell at you very loudly).
+
+# Version 0.7.0
+
+New features:
+* Support for encoding BigTiff ([#122](https://github.com/image-rs/image-tiff/pull/122))
+  * _Breaking:_ Encoder types now have a generic parameter to differentiate BigTiff and standard Tiff encoding. Defaults to standard Tiff.
+* Basic tile decoding ([#125](https://github.com/image-rs/image-tiff/pull/125))
+  * _Breaking:_ There is a new `TiffError::UsageError` variant.
+* Support for datatypes `Int8` and `Int16` ([#114](https://github.com/image-rs/image-tiff/pull/114))
+  * _Breaking:_ `DecodingResult` and `DecodingBuffer` have the two new variants `I8` and `I16`.
+* Support for `i32` arrays ([#118](https://github.com/image-rs/image-tiff/pull/118/files))
+  * _Breaking:_ `DecodingResult` and `DecodingBuffer` have a new `I32` variant.
+* Support for `Ifd` and `IfdBig` tag types and `I64` data type ([#119](https://github.com/image-rs/image-tiff/pull/119))
+  * _Breaking:_ `DecodingResult` and `DecodingBuffer` have a new `I64` variant.
+* Add `SMinSampleValue` and `SMaxSampleValue` ([#123](https://github.com/image-rs/image-tiff/pull/123))
+
+Changes:
+* Improve deflate support ([#132](https://github.com/image-rs/image-tiff/pull/132))
+  * Switch to streaming decompression via `flate2`. Aside from performance improvements and lower RAM consumption, this fixes a bug where `max_uncompressed_length` was precalculated for a single tile but then used as a hard limit on the whole data, failing to decompress any tiled images.
+  * Add support for new `Deflate` tag in addition to `OldDeflate`.
+* _Breaking:_ Remove `InflateError`, which is no longer needed with `flate2` ([#134](https://github.com/image-rs/image-tiff/pull/134))
+* _Breaking:_ Support for `MinIsWhite` is restricted to unsigned and floating
+  point values. This is expected to be be re-added once some contradictory
+  interpretation regarding semantics for signed values is resolved.
+
+Fixes:
+* Validate that ASCII tags are valid ASCII and end with a null byte ([#121](https://github.com/image-rs/image-tiff/pull/121))
+
+Internal:
+* Simplify decompression logic ([#126](https://github.com/image-rs/image-tiff/pull/126))
+* Simplify `expand_strip` ([#128](https://github.com/image-rs/image-tiff/pull/128))
+
+# Version 0.6.1
+
+New features:
+* Support for reading `u16` and ascii string tags.
+* Added `Limits::unlimited` for disabling all limits.
+* Added `ImageEncoder::rows_per_strip` to overwrite the default.
+
+Changes:
+* The default strip size for chunked encoding is now 1MB, up from 8KB. This
+  should lead to more efficient decoding and compression.
+
+Fixes:
+* Fixed a bug where LZW compressed strips could not be decoded, instead
+  returning an error `Inconsistent sizes encountered`.
+* Reading a tag with a complex type and a single value returns the proper Value
+  variant, instead of a vector with one entry.
+
+# Version 0.6.0
+
+New features:
+* Support for decoding BigTIFF with 64-bit offsets
+* The value types byte, `f32`, `f64` are now recognized
+* Support for Modern JPEG encoded images
+
+Improvements:
+* Better support for adding auxiliary tags before encoding image data
+* Switched to lzw decoder library `weezl` for performance
+* The `ColorType` trait now supports `SAMPLE_ENCODING` hints
+
+Fixes:
+* Fixed decoding of inline ASCII in tags
+* Fixed handling after null terminator in ASCII data
+* Recognize tile and sample format tags
+
+# Version 0.5.0
+
+* Added support for 32-bit and 64-bit decoded values.
+* Added CMYK(16|32|64) color type support.
+* Check many internal integer conversions to increase stability. This should
+  only lead to images being reported as faulty that would previously silently
+  break platform limits. If there are any false positives, please report them.
+* Remove an erroneous check of decoded length in lzw compressed images.
+
+# Version 0.4.0
+
+* Several enumerations are now non_exhaustive for future extensions.
+  These are `Tag`, `Type`, `Value`, `PhotometricInterpretation`,
+  `CompressionMethod`, `Predictor`.
+* Enums gained a dedicated method to convert to their TIFF variant value with
+  the specified type. Performing these conversions by casting the discriminant
+  with `as` is not guaranteed to be stable, except where documented explicitly.
+* Removed the num-derive and num dependencies.
+* Added support for decoding `deflate` compressed images.
+* Make the decoder `Limits` customizable by exposing members.
+* Fixed multi-page TIFF encoding writing incorrect offsets.
