Release Notes

urllib3/urllib3

v1.26.18

Compare Source

====================

• Made body stripped from HTTP requests changing the request method to GET after HTTP 303 "See Other" redirect responses.

v1.26.17

Compare Source

====================

• Added the Cookie header to the list of headers to strip from requests when redirecting to a different host. As before, different headers can be set via Retry.remove_headers_on_redirect. (#&#8203;3139 <https://github.com/urllib3/urllib3/pull/3139>_)

v1.26.16

Compare Source

====================

• Fixed thread-safety issue where accessing a PoolManager with many distinct origins would cause connection pools to be closed while requests are in progress (#&#8203;2954 <https://github.com/urllib3/urllib3/pull/2954>_)

v1.26.15

Compare Source

====================

• Fix socket timeout value when HTTPConnection is reused (#&#8203;2645 <https://github.com/urllib3/urllib3/issues/2645>__)
• Remove "!" character from the unreserved characters in IPv6 Zone ID parsing (#&#8203;2899 <https://github.com/urllib3/urllib3/issues/2899>__)
• Fix IDNA handling of '\x80' byte (#&#8203;2901 <https://github.com/urllib3/urllib3/issues/2901>__)

v1.26.14

Compare Source

====================

• Fixed parsing of port 0 (zero) returning None, instead of 0. (#&#8203;2850 <https://github.com/urllib3/urllib3/issues/2850>__)
• Removed deprecated getheaders() calls in contrib module. Fixed the type hint of PoolKey.key_retries by adding bool to the union. (#&#8203;2865 <https://github.com/urllib3/urllib3/issues/2865>__)

v1.26.13

Compare Source

====================

• Deprecated the HTTMResponse.getheaders() and HTTMResponse.getheader() methods.
• Fixed an issue where parsing a URL with leading zeroes in the port would be rejected even when the port number after removing the zeroes was valid.
• Fixed a deprecation warning when using cryptography v39.0.0.
• Removed the <4 in the Requires-Python packaging metadata field.

v1.26.12

Compare Source

====================

• Deprecated the urllib3[secure] extra and the urllib3.contrib.pyopenssl module. Both will be removed in v2.x. See this GitHub issue <https://github.com/urllib3/urllib3/issues/2680>_ for justification and info on how to migrate.

v1.26.11

Compare Source

====================

• Fixed an issue where reading more than 2 GiB in a call to HTTMResponse.read would raise an OverflowError on Python 3.9 and earlier.

v1.26.10

Compare Source

====================

• Removed support for Python 3.5
• Fixed an issue where a ProxyError recommending configuring the proxy as HTTP instead of HTTPS could appear even when an HTTPS proxy wasn't configured.

v1.26.9

Compare Source

===================

• Changed urllib3[brotli] extra to favor installing Brotli libraries that are still receiving updates like brotli and brotlicffi instead of brotlipy. This change does not impact behavior of urllib3, only which dependencies are installed.
• Fixed a socket leaking when HTTPSConnection.connect() raises an exception.
• Fixed server_hostname being forwarded from PoolManager to HTTPConnectionPool when requesting an HTTP URL. Should only be forwarded when requesting an HTTPS URL.

v1.26.8

Compare Source

===================

• Added extra message to urllib3.exceptions.ProxyError when urllib3 detects that a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
• Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
• Added explicit support for Python 3.11.
• Deprecated the Retry.MAX_BACKOFF class property in favor of Retry.DEFAULT_MAX_BACKOFF to better match the rest of the default parameter names. Retry.MAX_BACKOFF is removed in v2.0.
• Changed location of the vendored ssl.match_hostname function from urllib3.packages.ssl_match_hostname to urllib3.util.ssl_match_hostname to ensure Python 3.10+ compatibility after being repackaged by downstream distributors.
• Fixed absolute imports, all imports are now relative.

v1.26.7

Compare Source

===================

• Fixed a bug with HTTPS hostname verification involving IP addresses and lack of SNI. (Issue #​2400)
• Fixed a bug where IPv6 braces weren't stripped during certificate hostname matching. (Issue #​2240)

v1.26.6

Compare Source

===================

• Deprecated the urllib3.contrib.ntlmpool module. urllib3 is not able to support it properly due to reasons listed in this issue <https://github.com/urllib3/urllib3/issues/2282>_. If you are a user of this module please leave a comment.
• Changed HTTPConnection.request_chunked() to not erroneously emit multiple Transfer-Encoding headers in the case that one is already specified.
• Fixed typo in deprecation message to recommend Retry.DEFAULT_ALLOWED_METHODS.

v1.26.5

Compare Source

===================

• Fixed deprecation warnings emitted in Python 3.10.
• Updated vendored six library to 1.16.0.
• Improved performance of URL parser when splitting the authority component.

v1.26.4

Compare Source

===================

• Changed behavior of the default SSLContext when connecting to HTTPS proxy during HTTPS requests. The default SSLContext now sets check_hostname=True.

v1.26.3

Compare Source

===================

• Fixed bytes and string comparison issue with headers (Pull #​2141)

• Changed ProxySchemeUnknown error message to be more actionable if the user supplies a proxy URL without a scheme. (Pull #​2107)
