Version 3.5.5

3.5.5 (2024-03-25)

Added

• Support for Happy Eyeballs. This feature is disabled by default, you must pass happy_eyeballs=True within your session
  constructor or http adapter in order to leverage this.

Fixed

• Missed close implementation in AsyncSession causing the underlying poolmanager to remain open.
• Additional OCSP requests (following a redirect) did not use specified custom DNS resolver.

Changed

• urllib3.future lower bound constraint has been raised to version 2.7.900 for the newly added happy eyeballs feature.

Version 3.5.4

3.5.4 (2024-03-17)

Added

• Support to verify the peer certificate fingerprint using verify=... by passing a string using the following format:
  verify="sha256_748c76348778cb4a536e7ec12bc9aa559c12770bd1419c7ffe516006e1dea0ec". Doing so disable the certificate
  usual verification and only checks for its fingerprint match.

Fixed

• Multiplexed request in async did not support awaitable in hooks.
• Setting verify=... and cert=... then change it for the same host did not apply to the underlying (existing) connection pool.

Misc

• Overall performance improvements in both async and sync requests.
• Update pre-commit dependencies (ruff, pyupgrade, and mypy).
• Fixed SessionRedirect in tests that produced an incomplete Response instance that wasn't suitable for tests.

Version 3.5.3

3.5.3 (2024-03-07)

Fixed

• A rare error that occurs on PyPy, especially on Windows, complaining about a missing release call.

Misc

• Allow latest dependencies version for httpbin, Flask and werkzeug in tests.
• Remove wheel from test dependencies.

Version 3.5.2

3.5.2 (2024-03-05)

Fixed

• ImportError in an attempt to retrieve ConnectionInfo in niquests.utils.

Changed

• General performance improvements.

Version 3.5.0

3.5.0 (2024-02-29)

Changed

• Replaced the thread pool executor for the true asyncio implementation. The asynchronous part is rewritten.
• urllib3.future lower bound constraint has been raised to version 2.6.900 for the newly added asynchronous interfaces.

Added

• Support for awaitable hooks in AsyncSession.
• Extendable AsyncBaseAdapter.
• Support for orjson if installed in environment to dramatically increase performance in JSON deserialization.
• Extra speedups to increase overall performances by including optional dependencies such as zstandard, brotli and orjson.

Fixed

• A rare error when leveraging multiplexing when a proxy is used.
• Bypass proxies when looking to validate certificate revocation status in Python < 3.10 with OCSP.

Version 3.4.7

3.4.7 (2024-02-21)

Fixed

• Unintentional performance regression with multiple concurrent multiplexed connection within a single Session.

Version 3.4.6

3.4.6 (2024-02-21)

Fixed

• Unmatched filter for deprecation warning yielded by Cryptography due to some legacy CA available in Windows having a negative serial number.
• Setting boundary in Content-Type header with no value associated (no equal sign) can cause a rare error (multipart).
• Rare racing condition while emitting too many request across a multiplexed connections.
• Spawning too many threads while using AsyncSession in specific contexts.

Version 3.4.5

3.4.5 (2024-02-02)

Fixed

• Thread-safety issue when leveraging a single multiplexed connection across multiple threads.
• Apparently consumed content when allow_redirect is set to True when accessing a lazy response that follow redirects.

Changed

• urllib3.future lower bound constraint has been raised to version 2.5.900 in order to leverage the advanced multiplexing scheduler.
  This upgrade come with a noticeable performance bump with complex multiplexed requests.

Added

• Session constructor now accepts both pool_connections and pool_maxsize parameters to scale your pools of connections at will.

Version 3.4.4

3.4.4 (2024-01-19)

Fixed

• Issuing a request with Session(multiplexed=True) that weren't eligible (e.g. HTTP/1.1) but was redirected to an
  eligible server (HTTP/2+) caused a rare error.
• An anonymous netrc entry (e.g. username only) could be wrongfully used when it should be discarded. (PR #61)

Added

• Awaitable close method within AsyncSession.

Version 3.4.3

3.4.3 (2024-01-16)

Fixed

• Accessing a lazy response (multiplexed enabled) that have multiple redirects did not work appropriately.

Changed

• Response iter_content and iter_line read chunks as they arrive by default. The default chunk size is now -1.
  -1 mean to instruct that the chunks can be of variable sizes, depending on how packets arrives. It improves
  overall performances in content streaming.
• urllib3.future lower bound constraint has been raised to version 2.4.904 in order to accept -1 as a chunk size.
