Release Notes

tkem/cachetools

v5.0.0

Compare Source

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

• Require Python 3.7 or later (breaking change).

• Remove deprecated submodules (breaking change).

  The cache, fifo, lfu, lru, mru, rr and
  ttl submodules have been deleted. Therefore, statements like

  from cachetools.ttl import TTLCache

  will no longer work. Use

  from cachetools import TTLCache

  instead.

• Pass self to @cachedmethod key function (breaking change).

  The key function passed to the @cachedmethod decorator is
  now called as key(self, *args, **kwargs).

  The default key function has been changed to ignore its first
  argument, so this should only affect applications using custom key
  functions with the @cachedmethod decorator.

• Change exact time of expiration in TTLCache (breaking change).

  TTLCache items now get expired if their expiration time is less
  than or equal to timer(). For applications using the default
  timer(), this should be barely noticable, but it may affect the
  use of custom timers with larger tick intervals. Note that this
  also implies that a TTLCache with ttl=0 can no longer hold
  any items, since they will expire immediately.

• Change Cache.__repr__() format (breaking change).

  String representations of cache instances now use a more compact and
  efficient format, e.g.

  LRUCache({1: 1, 2: 2}, maxsize=10, currsize=2)

• Add TLRU cache implementation.

• Documentation improvements.

python/importlib_metadata

v4.10.0

Compare Source

=======

• #​354: Removed Distribution._local factory. This
  functionality was created as a demonstration of the
  possible implementation. Now, the
  pep517 <https://pypi.org/project/pep517>_ package
  provides this functionality directly through
  pep517.meta.load <https://github.com/pypa/pep517/blob/a942316305395f8f757f210e2b16f738af73f8b8/pep517/meta.py#L63-L73>_.

v4.9.0

Compare Source

======

• Require Python 3.7 or later.

psf/requests

v2.27.0

Compare Source

Improvements

• Officially added support for Python 3.10. (#​5928)

• Added a requests.exceptions.JSONDecodeError to unify JSON exceptions between
  Python 2 and 3. This gets raised in the response.json() method, and is
  backwards compatible as it inherits from previously thrown exceptions.
  Can be caught from requests.exceptions.RequestException as well. (#​5856)

• Improved error text for misnamed InvalidSchema and MissingSchema
  exceptions. This is a temporary fix until exceptions can be renamed
  (Schema->Scheme). (#​6017)

• Improved proxy parsing for proxy URLs missing a scheme. This will address
  recent changes to urlparse in Python 3.9+. (#​5917)

Bugfixes

• Fixed defect in extract_zipped_paths which could result in an infinite loop
  for some paths. (#​5851)

• Fixed handling for AttributeError when calculating length of files obtained
  by Tarfile.extractfile(). (#​5239)

• Fixed urllib3 exception leak, wrapping urllib3.exceptions.InvalidHeader with
  requests.exceptions.InvalidHeader. (#​5914)

• Fixed bug where two Host headers were sent for chunked requests. (#​5391)

• Fixed regression in Requests 2.26.0 where Proxy-Authorization was
  incorrectly stripped from all requests sent with Session.send. (#​5924)

• Fixed performance regression in 2.26.0 for hosts with a large number of
  proxies available in the environment. (#​5924)

• Fixed idna exception leak, wrapping UnicodeError with
  requests.exceptions.InvalidURL for URLs with a leading dot (.) in the
  domain. (#​5414)

Deprecations

• Requests support for Python 2.7 and 3.6 will be ending in 2022. While we
  don't have exact dates, Requests 2.27.x is likely to be the last release
  series providing support.

nox > Session py-3.6 was successful.

 Testing completed.

================================================================
2022-01-04T21:05:33Z: Build finished with 1 
================================================================

Not sure why Samples 3.6 failed? Will re-trigger a build.

Edit: Failure is in snippets/geography, due to zipp, which is only included because of a transitive dependency AFAIK.
