Compare Source

• add mypy annotations and mark it as checkable, #​76 by @​orborde
• enable trusted publishing, allowing GitHub Actions to publish releases to PyPI without long lived credentials, #​78 by @​alexprengere

v1.23

Compare Source

• add gzip to supported algorithms for streaming responses, but not in the COMPRESS_ALGORITHM_STREAMING default values, so users have to explicitly enable it
• add Windows and MacOS to the list of platforms tested on GitHub Actions

v1.22

Compare Source

• fix possible RuntimeError when applying compression to a streaming endpoint
• no longer apply make_conditional to streaming responses, as it had the effect of buffering the entire response, which defeats the purpose of streaming responses, unless the request.endpoint is in a new COMPRESS_STREAMING_ENDPOINT_CONDITIONAL config option, which defaults to ["static"]

As serving static content with Flask is using streaming responses, we wanted to preserve the correct handling of conditional requests (i.e. 304 Not Modified responses) for static content, while avoiding buffering the entire response when compressing streaming responses for other endpoints

v1.21

Compare Source

• compressing streaming responses is now supported:
  • the previous behavior was:
    • if COMPRESS_STREAMS was True (the default), streaming responses were compressed in 1 sitting using response.get_data(), meaning streaming responses were compressed but not streamed
    • if COMPRESS_STREAMS was False, streaming responses were not compressed at all
  • the new behavior is:
    • if COMPRESS_STREAMS is True, streaming responses are compressed chunk-by-chunk using response.iter_encoded(), which means that streaming responses are compressed and streamed
    • if COMPRESS_STREAMS is False, streaming responses are not compressed at all, as before.
  • we have a new COMPRESS_ALGORITHM_STREAMING config option to specify the compression algorithm to use for streaming responses, which defaults to ["zstd", "br", "deflate"], as "gzip" is not suitable for streaming compression.
  • ⚠️ serving static content with Flask is actually using streaming responses, so if you enable streaming compression, static content will be compressed chunk-by-chunk as well, which may not be what you want.

v1.20

Compare Source

• the new COMPRESS_EVALUATE_CONDITIONAL_REQUEST config option is now True by default

v1.19

Compare Source

• Use backports.zstd instead of pyzstd, #​63 by @​alexprengere
• Add new behaviours to improve Etag compatibility, #​67, by @​jlopex
  • weak etags are no longer modified by flask-compress
  • add new COMPRESS_EVALUATE_CONDITIONAL_REQUEST config option to call response.make_conditional(request) after compression, this ensures that 304 Not Modified responses are correctly generated when the client sends conditional requests with If-None-Match (defaults to False)

v1.18

Compare Source

• Support, and test against, Python 3.14, see #​61 by @​kurtmckee
• Migrate from zstandard to pyzstd, which is now included in the Python 3.14 standard library, also part of #​61
• Restore flask_compress.DictCache() that is needed to configure Flask-Compress with caching, without relying on Flask-Caching

v2.43.0

Compare Source

Features

• Add public wrapper for _mtls_helper.check_use_client_cert which enables mTLS if GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, when the MWID/X.509 cert sources detected (#​1859) Add public wrapper for check_use_client_cert which enables mTLS if
  GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, when the MWID/X.509 cert
  sources detected. Also, fix check_use_client_cert to return boolean
  value.
  Change #​1848 added the check_use_client_cert method that helps know if
  client cert should be used for mTLS connection. However, that was in a
  private class, thus, created a public wrapper of the same function so
  that it can be used by python Client Libraries. Also, updated
  check_use_client_cert to return a boolean value instead of existing
  string value for better readability and future scope.
  --------- (1535eccbff0ad8f3fd6a9775316ac8b77dca66ba)
• Enable mTLS if GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, if the MWID/X.509 cert sources detected (#​1848) The Python SDK will use a hybrid approach for mTLS enablement:

• If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is set
  (either true or false), the SDK will respect that setting. This is
  necessary for test scenarios and users who need to explicitly control
  mTLS behavior.
• If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not
  set, the SDK will automatically enable mTLS only if it detects Managed
  Workload Identity (MWID) or X.509 Workforce Identity Federation (WIF)
  certificate sources. In other cases where the variable is not set, mTLS
  will remain disabled.
  ** This change also adds the helper method check_use_client_cert and
  it's unit test, which will be used for checking the criteria for setting
  the mTLS to true
  ** This change is only for Auth-Library, other changes will be created
  for Client-Library use-cases.

What's new in Pylint 3.3.9?

Release date: 2025-10-05

False Positives Fixed

• Fix used-before-assignment for PEP 695 type aliases and parameters.

  Closes #​9815

• No longer flag undeprecated functions in importlib.resources as deprecated.

  Closes #​10593

• Fix false positive inconsistent-return-statements when using quit() or exit() functions.

• Fix false positive undefined-variable (E0602) for for-loop variable shadowing patterns like for item in item: when the variable was previously defined.

  Closes #​10562

Other Bug Fixes

• Fixed crash in 'unnecessary-list-index-lookup' when starting an enumeration using
  minus the length of an iterable inside a dict comprehension when the len call was only
  made in this dict comprehension, and not elsewhere. Also changed the approach,
  to use inference in all cases but the simple ones, so we don't have to fix crashes
  one by one for arbitrarily complex expressions in enumerate.
