Fixed a socket leak when fingerprint or hostname verifications fail. ([#2991](https://github.com/urllib3/urllib3/issues/2991) <https://github.com/urllib3/urllib3/issues/2991>__)
Fixed an error when HTTPResponse.read(0) was the first read call or when the internal response body buffer was otherwise empty. ([#2998](https://github.com/urllib3/urllib3/issues/2998) <https://github.com/urllib3/urllib3/issues/2998>__)
2.0.0 (2023-04-26)
Read the v2.0 migration guide <https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html>__ for help upgrading to the latest version of urllib3.
Removed
Removed support for Python 2.7, 3.5, and 3.6 ([#883](https://github.com/urllib3/urllib3/issues/883) <https://github.com/urllib3/urllib3/issues/883>, [#2336](https://github.com/urllib3/urllib3/issues/2336) <https://github.com/urllib3/urllib3/issues/2336>).
Removed fallback on certificate commonName in match_hostname() function.
This behavior was deprecated in May 2000 in RFC 2818. Instead only subjectAltName
is used to verify the hostname by default. To enable verifying the hostname against
commonName use SSLContext.hostname_checks_common_name = True ([#2113](https://github.com/urllib3/urllib3/issues/2113) <https://github.com/urllib3/urllib3/issues/2113>__).
Removed support for Python with an ssl module compiled with LibreSSL, CiscoSSL,
wolfSSL, and all other OpenSSL alternatives. Python is moving to require OpenSSL with PEP 644 ([#2168](https://github.com/urllib3/urllib3/issues/2168) <https://github.com/urllib3/urllib3/issues/2168>__).
Removed support for OpenSSL versions earlier than 1.1.1 or that don't have SNI support.
When an incompatible OpenSSL version is detected an ImportError is raised ([#2168](https://github.com/urllib3/urllib3/issues/2168) <https://github.com/urllib3/urllib3/issues/2168>__).
Removed the list of default ciphers for OpenSSL 1.1.1+ and SecureTransport as their own defaults are already secure ([#2082](https://github.com/urllib3/urllib3/issues/2082) <https://github.com/urllib3/urllib3/issues/2082>__).
Removed urllib3.contrib.appengine.AppEngineManager and support for Google App Engine Standard Environment ([#2044](https://github.com/urllib3/urllib3/issues/2044) <https://github.com/urllib3/urllib3/issues/2044>__).
Removed default value of None for the request_context parameter of urllib3.PoolManager.connection_from_pool_key. This change should have no effect on users as the default value of None was an invalid option and was never used ([#1897](https://github.com/urllib3/urllib3/issues/1897) <https://github.com/urllib3/urllib3/issues/1897>__).
Removed the urllib3.request module. urllib3.request.RequestMethods has been made a private API.
This change was made to ensure that from urllib3 import request imported the top-level request()
function instead of the urllib3.request module ([#2269](https://github.com/urllib3/urllib3/issues/2269) <https://github.com/urllib3/urllib3/issues/2269>__).
Removed support for SSLv3.0 from the urllib3.contrib.pyopenssl even when support is available from the compiled OpenSSL library ([#2233](https://github.com/urllib3/urllib3/issues/2233) <https://github.com/urllib3/urllib3/issues/2233>__).
Removed the deprecated urllib3.contrib.ntlmpool module ([#2339](https://github.com/urllib3/urllib3/issues/2339) <https://github.com/urllib3/urllib3/issues/2339>__).
Removed DEFAULT_CIPHERS, HAS_SNI, USE_DEFAULT_SSLCONTEXT_CIPHERS, from the private module urllib3.util.ssl_ ([#2168](https://github.com/urllib3/urllib3/issues/2168) <https://github.com/urllib3/urllib3/issues/2168>__).
Removed the _prepare_conn method from HTTPConnectionPool. Previously this was only used to call HTTPSConnection.set_cert() by HTTPSConnectionPool ([#1985](https://github.com/urllib3/urllib3/issues/1985) <https://github.com/urllib3/urllib3/issues/1985>__).
Removed tls_in_tls_required property from HTTPSConnection. This is now determined from the scheme parameter in HTTPConnection.set_tunnel() ([#1985](https://github.com/urllib3/urllib3/issues/1985) <https://github.com/urllib3/urllib3/issues/1985>__).
Deprecated
Deprecated HTTPResponse.getheaders() and HTTPResponse.getheader() which will be removed in urllib3 v2.1.0. Instead use HTTPResponse.headers and HTTPResponse.headers.get(name, default). ([#1543](https://github.com/urllib3/urllib3/issues/1543) <https://github.com/urllib3/urllib3/issues/1543>, [#2814](https://github.com/urllib3/urllib3/issues/2814) <https://github.com/urllib3/urllib3/issues/2814>).
Deprecated urllib3.contrib.pyopenssl module which will be removed in urllib3 v2.1.0 ([#2691](https://github.com/urllib3/urllib3/issues/2691) <https://github.com/urllib3/urllib3/issues/2691>__).
Deprecated urllib3.contrib.securetransport module which will be removed in urllib3 v2.1.0 ([#2692](https://github.com/urllib3/urllib3/issues/2692) <https://github.com/urllib3/urllib3/issues/2692>__).
Deprecated ssl_version option in favor of ssl_minimum_version. ssl_version will be removed in urllib3 v2.1.0 ([#2110](https://github.com/urllib3/urllib3/issues/2110) <https://github.com/urllib3/urllib3/issues/2110>__).
Deprecated the strict parameter as it's not longer needed in Python 3.x. It will be removed in urllib3 v2.1.0 ([#2267](https://github.com/urllib3/urllib3/issues/2267) <https://github.com/urllib3/urllib3/issues/2267>__)
