⚠️ urllib3 v2.0 will drop support for Python 2: Read more in the v2.0 Roadmap

⚠️ This release will be the last release supporting Python 3.5. Please upgrade to a non-EOL Python version.

• 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.

We're seeing an issue similar to #775 (comment) here.
i.e., The requirements.in file is updated for all microservices containing the dependency — but the requirements.txt file is only updated for one microservice.

[NimJay]

All requirements.txt files are now updated thanks to #780.

But now we're seeing a Python dependency error in the "deployment-tests" check, when a Dockerfile runs:

pip install --prefix="/install" -r requirements.txt

Here's the error message:

ERROR: Could not find a version that satisfies the requirement charset-normalizer==2.0.10 (from versions: 0.1a0, 0.1.1a0, 0.1.2b0, 0.1.4b0, 0.1.5b0, 0.1.7, 0.1.8, 0.2.0, 0.2.1, 0.2.2, 0.2.3, 0.3.0, 1.0.0, 1.1.0, 1.1.1, 1.2.0, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.3.8, 1.3.9, 1.4.0, 1.4.1, 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.0.7, 2.0.8, 2.0.9)

I did a quick test of the staging URL.
Looks good to me.
Plus, it's not a major bump.
