-------------------
**Improvements**
- Requests now supports Brotli compression, if either the `brotli` or
`brotlicffi` package is installed. (5783)
- `Session.send` now correctly resolves proxy configurations from both
the Session and Request. Behavior now matches `Session.request`. (5681)
**Bugfixes**
- Fixed a race condition in zip extraction when using Requests in parallel
from zip archive. (5707)
**Dependencies**
- Instead of `chardet`, use the MIT-licensed `charset_normalizer` for Python3
to remove license ambiguity for projects bundling requests. If `chardet`
is already installed on your machine it will be used instead of `charset_normalizer`
to keep backwards compatibility. (5797)
You can also install `chardet` while installing requests by
specifying `[use_chardet_on_py3]` extra as follows:
shell
pip install "requests[use_chardet_on_py3]"
Python2 still depends upon the `chardet` module.
- Requests now supports `idna` 3.x on Python 3. `idna` 2.x will continue to
be used on Python 2 installations. (5711)
**Deprecations**
- The `requests[security]` extra has been converted to a no-op install.
PyOpenSSL is no longer the recommended secure option for Requests. (5867)
- Requests has officially dropped support for Python 3.5. (5867)
