## What do these changes do? Mypy will add a `--strict-bytes` flag. python/mypy#18263 With that `bytearray` and `memoryview` are no longer subclasses of `bytes` and must be listed explicitly instead if they are supported. ## Are there changes in behavior for the user? -- ## Related issue number -- ## Checklist - [ ] I think the code is well written - [ ] Unit tests for the changes exist - [ ] Documentation reflects the changes - [ ] If you provide code modification, please add yourself to `CONTRIBUTORS.txt` * The format is <Name> <Surname>. * Please keep alphabetical order, the file is sorted by names. - [ ] Add a new news fragment into the `CHANGES/` folder * name it `<issue_or_pr_num>.<type>.rst` (e.g. `588.bugfix.rst`) * if you don't have an issue number, change it to the pull request number after creating the PR * `.bugfix`: A bug fix for something the maintainers deemed an improper undesired behavior that got corrected to match pre-agreed expectations. * `.feature`: A new behavior, public APIs. That sort of stuff. * `.deprecation`: A declaration of future API removals and breaking changes in behavior. * `.breaking`: When something public is removed in a breaking way. Could be deprecated in an earlier release. * `.doc`: Notable updates to the documentation structure or build process. * `.packaging`: Notes for downstreams about unobvious side effects and tooling. Changes in the test invocation considerations and runtime assumptions. * `.contrib`: Stuff that affects the contributor experience. e.g. Running tests, building the docs, setting up the development environment. * `.misc`: Changes that are hard to assign to any of the above categories. * Make sure to use full sentences with correct case and punctuation, for example: ```rst Fixed issue with non-ascii contents in doctest text files -- by :user:`contributor-gh-handle`. ``` Use the past tense or the present tense a non-imperative mood, referring to what's changed compared to the last released version of this project. --------- Co-authored-by: J.
