Changelog

Sourced from urllib3's changelog.

2.0.4 (2023-07-19)

• Added support for union operators to HTTPHeaderDict ([#2254](https://github.com/urllib3/urllib3/issues/2254) <https://github.com/urllib3/urllib3/issues/2254>__)
• Added BaseHTTPResponse to urllib3.__all__ ([#3078](https://github.com/urllib3/urllib3/issues/3078) <https://github.com/urllib3/urllib3/issues/3078>__)
• Fixed urllib3.connection.HTTPConnection to raise the http.client.connect audit event to have the same behavior as the standard library HTTP client ([#2757](https://github.com/urllib3/urllib3/issues/2757) <https://github.com/urllib3/urllib3/issues/2757>__)
• Relied on the standard library for checking hostnames in supported PyPy releases ([#3087](https://github.com/urllib3/urllib3/issues/3087) <https://github.com/urllib3/urllib3/issues/3087>__)

2.0.3 (2023-06-07)

• Allowed alternative SSL libraries such as LibreSSL, while still issuing a warning as we cannot help users facing issues with implementations other than OpenSSL. ([#3020](https://github.com/urllib3/urllib3/issues/3020) <https://github.com/urllib3/urllib3/issues/3020>__)
• Deprecated URLs which don't have an explicit scheme ([#2950](https://github.com/urllib3/urllib3/issues/2950) <https://github.com/urllib3/urllib3/pull/2950>_)
• Fixed response decoding with Zstandard when compressed data is made of several frames. ([#3008](https://github.com/urllib3/urllib3/issues/3008) <https://github.com/urllib3/urllib3/issues/3008>__)
• Fixed assert_hostname=False to correctly skip hostname check. ([#3051](https://github.com/urllib3/urllib3/issues/3051) <https://github.com/urllib3/urllib3/issues/3051>__)

2.0.2 (2023-05-03)

• Fixed HTTPResponse.stream() to continue yielding bytes if buffered decompressed data was still available to be read even if the underlying socket is closed. This prevents a compressed response from being truncated. ([#3009](https://github.com/urllib3/urllib3/issues/3009) <https://github.com/urllib3/urllib3/issues/3009>__)

2.0.1 (2023-04-30)

• 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>__).
