Updates anyio from 4.12.1 to 4.14.2

Release notes

Sourced from anyio's releases.

4.14.2

• Changed ByteReceiveStream.receive() implementations to raise a ValueError when max_bytes is not a positive integer (#1191)
• Fixed CapacityLimiter.total_tokens rejecting float("inf") when the limiter was instantiated outside of an event loop. The adapter setter checked for infinity by identity (value is math.inf), so only the exact math.inf singleton was accepted, while every backend setter (using math.isinf()) accepts any positive infinity (#1189; PR by @​greymoth-jp).
• Fixed to_process.run_sync() deadlocking when the worker function writes enough data to sys.stderr to fill the (undrained) pipe buffer. The worker process now redirects sys.stderr to os.devnull as well, matching the documented behavior
• Fixed TLSStream.wrap() matching an internationalized (unicode) host name against the peer certificate using IDNA 2003 (via the standard library) instead of IDNA 2008, which could cause the host name to be matched against the wrong certificate (#1208)
• Fixed anyio.open_process() (and run_process()) ignoring the extra_groups argument, as it mistakenly passed the value of the group argument instead (#1209)
• Fixed CapacityLimiter.acquire_nowait() and CapacityLimiter.acquire_nowait_on_behalf_of() raising trio.WouldBlock instead of anyio.WouldBlock on the trio backend when there are no tokens available (#1218)
• Fixed CapacityLimiter on the asyncio backend over-granting tokens (borrowed_tokens exceeding total_tokens and available_tokens going negative) when a non-blocking acquire was made in the window between a token being released and the notified waiter resuming. The freed token is now reserved for the woken waiter right away, so the non-blocking acquire correctly raises WouldBlock (#1170; PR by @​gaoflow)
• Fixed unnecessary CPU spin when delivering cancellation from CancelScope on asyncio under certain conditions, including improper cancel scope nesting (#1111)

4.14.1

• Fixed teardown of higher-scoped async fixtures failing on asyncio with RuntimeError: Attempted to exit cancel scope in a different task than it was entered in when an async test raise an outcome exception (e.g., pytest.skip(), pytest.xfail(), or pytest.fail()) (#1179; PR by @​EmmanuelNiyonshuti)
• Fixed CapacityLimiter.total_tokens rejecting a value of 0 when the limiter was instantiated outside of an event loop, contradicting the documented behavior of allowing 0 total tokens (#1183; PR by @​nyxst4ck)

4.14.0

• Added support for Python 3.15

• Added an asynchronous implementation of the itertools module (#998; PR by @​11kkw)

• Added the local_port parameter to connect_tcp() to allow binding to a specific local port before connecting (#1067; PR by @​nullwiz)

• Added support for custom capacity limiters in async path and file I/O functions and classes

• Added the create_task() task group method for easier asyncio migration (returns a TaskHandle) (#1098)

• Changed TaskGroup.start_soon() to return a TaskHandle

• Added an option for TaskGroup.start() to return a TaskHandle (which then contains the start value in the start_value property)

• Added the cancel() convenience method to TaskGroup as a shortcut for cancelling the task group's cancel scope

• Improved the error message when a known backend is not installed to suggest the install command (#1115; PR by @​EmmanuelNiyonshuti)

• Improved anyio.Path to preserve subclass types by returning Self in methods that return path objects (#1130; PR by @​EmmanuelNiyonshuti)

• Changed the parameter type annotation in anyio.Path.write_bytes() to accept any ReadableBuffer, thus allowing it to accept bytearray and memoryview to match pathlib.Path.write_bytes() (#1135; PR by @​SAY-5)

• Changed several type annotations to only accept callables returning coroutine-like objects instead of arbitrary awaitables:

  • TaskGroup.start_soon()
  • TaskGroup.start()
  • anyio.from_thread.run()

  This reverts an earlier change from v3.7.0 which was made in error. (#1153)

• Changed anyio.run to support callables returning arbitrary awaitables at runtime on all backends. Previously, this only worked on asyncio (#1171; PR by @​gschaffner)

• Changed several classes (and their subclasses) to have __slots__ (with __weakref__):

  • anyio.CancelScope

Changelog

Sourced from pyjwt's changelog.

v2.15.0 <https://github.com/jpadilla/pyjwt/compare/2.14.0...2.15.0>__

Security

- Wrap recursion errors from deeply nested JWT payloads in ``DecodeError``
  instead of exposing a raw ``RecursionError``.
Added

- Support Python 3.15 by @kytta in `[#1202](https://github.com/jpadilla/pyjwt/issues/1202) <https://github.com/jpadilla/pyjwt/pull/1202>`__
Changed



JWKSetCache now stores the parsed PyJWKSet rather than the raw JWKS
payload, so a cache hit no longer re-parses every key. JWKSetCache.put()
accepts either form and raises PyJWKSetError for anything else. As a
result, PyJWKClient.get_jwk_set() returns the same PyJWKSet instance
for as long as it stays cached, rather than a freshly built one per call in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>__
PyJWKClient.fetch_data() now raises
PyJWKClientError("The JWKS endpoint did not return a JSON object") when
the endpoint response is not a JSON object, instead of returning it for
get_jwk_set() to reject. Callers reaching the JWKS through
get_jwk_set() see the same error as before in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>__

Fixed

- Return cached ``PyJWKSet`` values from ``PyJWKClient.get_jwk_set()`` instead
  of raising ``PyJWKClientError("The JWKS endpoint did not return a JSON
  object")``. ``JWKSetCache.put()`` documents ``PyJWKSet`` as the cached value,
  so callers pre-populating the cache to avoid a network round-trip could not
  read it back in `[#914](https://github.com/jpadilla/pyjwt/issues/914) <https://github.com/jpadilla/pyjwt/issues/914>`__ and
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>`__
- ``PyJWKClient.get_jwk_set()`` now caches the key set it returns, so a
  ``fetch_data()`` override that filters or transforms the JWKS is no longer
  undone by the next cache hit in
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>`__
- Raise the documented ``PyJWTError`` subclass instead of leaking a
  ``TypeError`` when the ``exp``, ``nbf``, or ``iat`` claim decodes to a
  non-numeric, non-string value such as a list, dict, or ``null``.
- Reject OKP JWK private keys when their public ``x`` component does not
  match the private ``d`` component.
- Treat malformed JWK Set members as unusable keys rather than letting
  ``AttributeError`` or ``TypeError`` escape ``PyJWKSet``. A member that is not

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. (#5095)

Changelog
Sourced from virtualenv's changelog.

Bugfixes - 21.7.13

Fix activate and activate.fish running commands embedded in the virtual environment path or in the
interpreter's Tcl/Tk library paths. (:issue:3252)


v21.7.12 (2026-09-18)

Bugfixes - 21.7.12

Fix activate.bat running arbitrary commands from a crafted --prompt, VIRTUALENV_PROMPT, or config file
value. (:issue:3250)
Verify a downloaded seed wheel's sha256 against PyPI before seeding it into a virtual environment, skipped when a
custom pip index is configured. (:issue:3251)


v21.7.11 (2026-09-17)

Bugfixes - 21.7.11

Running activate.bat again before deactivate no longer makes deactivate leave the environment's
PKG_CONFIG_PATH, TCL_LIBRARY and TK_LIBRARY behind, or lose values the user had set before the first
activation - by :user:darrenhuai. (:issue:3245)
Write pyvenv.cfg values on a single line, so a prompt carrying a line boundary can no longer inject configuration.
--prompt, the VIRTUALENV_PROMPT environment variable and the config file all set the prompt, and
pyvenv.cfg has no escape syntax, so a newline, a carriage return, or any other boundary str.splitlines
recognizes, such as U+2028, started a new configuration line. Reading the file back picked up those lines as keys,
and since the last value for a key wins, they replaced anything written earlier, including home. (:issue:3247)

Improved Documentation - 21.7.11

Document the policy for AI-assisted contributions and the licensing rules for dependencies. (:issue:3239)
