2.27.1 (2022-01-05)
-------------------
**Bugfixes**
- Fixed parsing issue that resulted in the `auth` component being
dropped from proxy URLs.
2.27.0 (2022-01-03)
-------------------
**Improvements**
- Officially added support for Python 3.10.
- Added a `requests.exceptions.JSONDecodeError` to unify JSON exceptions between
Python 2 and 3. This gets raised in the `response.json()` method, and is
backwards compatible as it inherits from previously thrown exceptions.
Can be caught from `requests.exceptions.RequestException` as well.
- Improved error text for misnamed `InvalidSchema` and `MissingSchema`
exceptions. This is a temporary fix until exceptions can be renamed
(Schema->Scheme).
- Improved proxy parsing for proxy URLs missing a scheme. This will address
recent changes to `urlparse` in Python 3.9+.
**Bugfixes**
- Fixed defect in `extract_zipped_paths` which could result in an infinite loop
for some paths.
- Fixed handling for `AttributeError` when calculating length of files obtained
by `Tarfile.extractfile()`.
- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.InvalidHeader` with
`requests.exceptions.InvalidHeader`.
- Fixed bug where two Host headers were sent for chunked requests.
- Fixed regression in Requests 2.26.0 where `Proxy-Authorization` was
incorrectly stripped from all requests sent with `Session.send`.
- Fixed performance regression in 2.26.0 for hosts with a large number of
proxies available in the environment.
- Fixed idna exception leak, wrapping `UnicodeError` with
`requests.exceptions.InvalidURL` for URLs with a leading dot (.) in the
domain.
**Deprecations**
- Requests support for Python 2.7 and 3.6 will be ending in 2022. While we
don't have exact dates, Requests 2.27.x is likely to be the last release
series providing support.
