.. towncrier release notes start

4.0.3 (2026-09-23)

  • Importing filelock on CPython 3.10 or 3.11 no longer makes new threads fail with RuntimeError: Cannot install a trace function while another trace function is being installed under coverage or a debugger. filelock skips its fork-safety audit hook there, so forking from inside a thread's own lock-state transition no longer raises immediately on those versions. :pr:747

4.0.2 (2026-09-23)

  • Concurrent acquire() and release() on a thread_local=False lock no longer leak the OS lock, close a descriptor twice, drop a lease token, or leave a false deadlock after a cross-thread release (:issue:744). :pr:745
  • :class:~filelock.AsyncReadWriteLock and :class:~filelock.AsyncSoftReadWriteLock now give each asyncio task its own hold, so tasks sharing one instance no longer enter the write lock together. :pr:746
  • Correct the async cache example to create its data directory and clarify automatic creation of lock-file parent directories. :pr:740
  • Exclude sphinx-llm 1.1.0 from documentation dependencies because its Markdown builder emits unknown-node warnings. :pr:742

4.0.1 (2026-09-19)

  • poll_interval is now validated at construction, on the setter, and on acquire(): a negative, non-finite, or non-numeric value raises :class:ValueError/:class:TypeError immediately instead of failing inside time.sleep. :pr:739

4.0.0 (2026-09-17)

  • The :class:~filelock.SoftReadWriteLock on-disk protocol is a generation log under <path>.rw, and a process running an earlier release does not see it: an old and a new participant on one lock path do not exclude each other. Stop every participant, upgrade them all, then restart them; the new code ignores leftover .state, .write and .readers/ files, and you can delete them. The filesystem must provide no-replace hard links, as it must for :class:~filelock.StrictSoftFileLock, so a runtime without os.link raises :class:~filelock.SoftFileLockProtocolError on acquire. Constructing a singleton again with a different on_compromise, or with poll_interval at or above stale_threshold, now raises :class:ValueError. :pr:735
  • :class:~filelock.SoftReadWriteLock exposes :attr:~filelock.SoftReadWriteLock.generation as a fencing token for the protected resource and reports a lost hold through on_compromise and :attr:~filelock.SoftReadWriteLock.compromise. :pr:735
  • :class:~filelock.SoftReadWriteLock no longer deadlocks when a holder dies on another host mid-transition, and

Updates urllib3 from 2.7.0 to 2.8.0

Release notes

Sourced from urllib3's releases.

2.8.0

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Security

Fixed the following security issues:

  • The TLS configuration for HTTPS proxies could be ignored or overridden. (High severity, GHSA-8988-9cw3-xx77)
  • HTTPResponse.stream() and read_chunked() could buffer a chunk-size line of unbounded length in memory. (High severity, GHSA-vxq7-64xx-v4gw)
  • Chunked Deflate streaming could enter an infinite loop. (Medium severity, GHSA-gh4c-6fx4-qh6g)

[!IMPORTANT] urllib3 2.8.0 fixes HTTPS proxy TLS configuration being ignored or overridden by destination settings. Configurations relying on that behavior may require changes.

Configure proxy CA certificates and client certificates in proxy_ssl_context, and proxy identity checks with proxy_assert_hostname or proxy_assert_fingerprint. Destination client certificates and identity overrides no longer apply to HTTPS forwarding proxy connections.

[!NOTE] CVE IDs had not yet been assigned to these advisories at the time of release due to a backlog at GitHub's CNA.

Deprecations & Removals

  • Deprecated using an empty collection as the Retry option allowed_methods to retry any verb. (#5044)

Features

  • Added Url.auth_decoded and Url.auth_decoded_joined convenience properties to the result of parse_url(). (#4945)
  • Added basic_auth_encoding and proxy_basic_auth_encoding parameters to urllib3.util.make_headers(). (#5092)

Bugfixes

  • Fixed response header handling to replace obsolete folded header lines (obs-fold) with spaces in accordance with RFC 9112, preventing raw CRLF sequences from appearing in header values such as Set-Cookie. (#1362)

  • Fixed usage of proxy_ssl_context with ProxyManager when use_forwarding_for_https=True. Passing ssl_context instead of proxy_ssl_context for HTTPS proxies in this configuration now emits a FutureWarning and will raise an error in v3.0. (#2577)

  • Changed behavior of the default ConnectionPool.pool initialization. LifoQueue is now resolved from the queue module after the ConnectionPool is instantiated instead of using the default cached QueueCls class property. This is done because sometimes the queue.LifoQueue is monkey-patched late in the program, such as by gevent. (#3289)

  • Raised UnrewindableBodyError instead of ValueError when retrying a request whose body had tell() but not seek(). (#3779)

  • Decoded percent-encoded SOCKS proxy credentials before authenticating with the proxy server. (#3785)

  • Fixed HTTPResponse.drain_conn() to discard unread response data in 64 KiB chunks (same as the default amt when doing HTTPResponse.stream(...)). (#5019)

  • Fixed is_ipaddress() to detect non-standard IPv4 forms accepted by socket.connect, such as hex (0x7f000001), octal (0177.0.0.1), and decimal integers (2130706433), ensuring SSL certificate verification uses the correct mode for these addresses. (#5029)

  • Fixed HTTPConnectionPool.urlopen raising a misleading FullPoolError instead of ValueError when called with an invalid timeout argument on a pool created with block=True. (#5059)

  • Fixed port-zero handling to preserve explicit :0 values instead of substituting the default ports 80 or 443 in URL parsing, pool selection, proxy configuration, connection_from_url(), and HTTP/2 request authority. (#5071, #5101)

  • Fixed a bug where PoolManager passed the assert_hostname and assert_fingerprint parameters to HTTP connection pools. (#5077)

  • Fixed HTTPConnectionPool.urlopen() and HTTP proxy forwarding to strip URL fragments from absolute request targets before sending requests. (#5079)

  • Added safeguards to the proxy tunneling code to prevent potential security issues when handling invalid characters in the proxy host and HTTP headers. This change affects users of Python 3.10, Python 3.11, and Python 3.12 when the standard library does not contain the fix; those on newer Python versions should upgrade to 3.13.14+ or 3.14.5+ to get the same security fixes. (#5091)

  • Fixed HTTPSConnection.connect() overriding ProxyConfig.ssl_context's certificate policy and proxy identity checks with the target connection's TLS settings when forwarding through an HTTPS proxy.

    HTTPSConnection no longer applies target SNI, assertions, or client credentials to forwarding proxy handshakes and continues to use its ssl_context as a fallback when an HTTPS proxy forwards an HTTP target. (#5093)

  • Fixed URL parsing to more strictly enforce RFC 3986 host syntax, rejecting invalid host input such as raw spaces and control characters, malformed percent-encodings, and percent-encoded control characters in HTTP(S) hosts and IPv6 zone identifiers, including proxy CONNECT tunnel targets. Host normalization now also follows RFC 3986 normalization rules for percent-encoded octets by decoding percent-encoded unreserved characters and uppercasing the hexadecimal digits of retained percent-encoded octets.

  • The TLS configuration for HTTPS proxies could be ignored or overridden. (High severity, GHSA-8988-9cw3-xx77 <https://github.com/urllib3/urllib3/security/advisories/GHSA-8988-9cw3-xx77>__)
  • HTTPResponse.stream() and read_chunked() could buffer a chunk-size line of unbounded length in memory. (High severity, GHSA-vxq7-64xx-v4gw <https://github.com/urllib3/urllib3/security/advisories/GHSA-vxq7-64xx-v4gw>__)
  • Chunked Deflate streaming could enter an infinite loop. (Medium severity, GHSA-gh4c-6fx4-qh6g <https://github.com/urllib3/urllib3/security/advisories/GHSA-gh4c-6fx4-qh6g>__)

.. caution::

urllib3 2.8.0 fixes HTTPS proxy TLS configuration being ignored or
overridden by destination settings. Configurations relying on that
behavior may require changes.

Configure proxy CA certificates and client certificates in
proxy_ssl_context, and proxy identity checks with
proxy_assert_hostname or proxy_assert_fingerprint.
Destination client certificates and identity overrides no longer
apply to HTTPS forwarding proxy connections.

Deprecations & Removals

  • Deprecated using an empty collection as the Retry option allowed_methods to retry any verb. ([#5044](https://github.com/urllib3/urllib3/issues/5044) <https://github.com/urllib3/urllib3/issues/5044>__)

Features

  • Added Url.auth_decoded and Url.auth_decoded_joined convenience properties to the result of parse_url(). ([#4945](https://github.com/urllib3/urllib3/issues/4945) <https://github.com/urllib3/urllib3/issues/4945>__)
  • Added basic_auth_encoding and proxy_basic_auth_encoding parameters to urllib3.util.make_headers(). ([#5092](https://github.com/urllib3/urllib3/issues/5092) <https://github.com/urllib3/urllib3/issues/5092>__)
