### [`v2.28.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2280-2022-06-09) **Deprecations** - ⚠️ Requests has officially dropped support for Python 2.7. ⚠️ ([#6091](https://togithub.com/psf/requests/issues/6091)) - Requests has officially dropped support for Python 3.6 (including pypy3.6). ([#6091](https://togithub.com/psf/requests/issues/6091)) **Improvements** - Wrap JSON parsing issues in Request's JSONDecodeError for payloads without an encoding to make `json()` API consistent. ([#6097](https://togithub.com/psf/requests/issues/6097)) - Parse header components consistently, raising an InvalidHeader error in all invalid cases. ([#6154](https://togithub.com/psf/requests/issues/6154)) - Added provisional 3.11 support with current beta build. ([#6155](https://togithub.com/psf/requests/issues/6155)) - Requests got a makeover and we decided to paint it black. ([#6095](https://togithub.com/psf/requests/issues/6095)) **Bugfixes** - Fixed bug where setting `CURL_CA_BUNDLE` to an empty string would disable cert verification. All Requests 2.x versions before 2.28.0 are affected. ([#6074](https://togithub.com/psf/requests/issues/6074)) - Fixed urllib3 exception leak, wrapping `urllib3.exceptions.SSLError` with `requests.exceptions.SSLError` for `content` and `iter_content`. ([#6057](https://togithub.com/psf/requests/issues/6057)) - Fixed issue where invalid Windows registry entires caused proxy resolution to raise an exception rather than ignoring the entry. ([#6149](https://togithub.com/psf/requests/issues/6149)) - Fixed issue where entire payload could be included in the error message for JSONDecodeError. ([#6036](https://togithub.com/psf/requests/issues/6036))
