-### Version 0.20.0 (unreleased)
- - Refactor of internal code.
- - Implement unix-specific permissions copying for `-p` option
- - Performance optimizations
+### Version 1.0.0
  - Remove the C dependency on miniz, and replace it with a Rust version ([#57](https://github.com/shssoichiro/oxipng/issues/57))
     - This improves decompression speed by 15%. Compression speed is not affected.
     - [SEMVER_MAJOR] This also obsoletes the `-zm` command line option and the `memory` key on the `Options` struct.
     - Presets will be updated automatically. This means that presets 3 and higher will run significantly more quickly.
- - Adjust the presets, now that memory is no longer an option.
+ - [SEMVER_MAJOR] Adjust the presets, now that `-zm` is no longer an option.
     - `-o3` now tests all filter types. This will result in 50% more trials than before, but may give up to 10% more compression gain.
-    - `-o4` and higher now test all alpha optimization types. This adds 5 trials specific to the alpha channel. Only transparent images are affected.
