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)

v3.35.0

Summary

This release includes an important security improvement for Data Masking and a significant cold start optimization for Parser.

We are happy to welcome six new contributors in this release: @​Adityaj0, @​manshahH, @​ErezMizrahi, @​wuodar, @​MohammedAlkindi, and @​TanbirRamim. Thank you for taking the time to report problems, work through reviews, and improve the prokject.

Data Masking now fails closed

Previously, an error while applying a masking rule could emit a warning and return the original value unchanged. Since callers received a normal return value, they could continue logging or storing data believing that masking had succeeded.

Data Masking now raises DataMaskingError when a masking provider fails, a masking path is invalid, or a regular expression cannot be compiled. Existing Data Masking exceptions now inherit from this common base exception.

from aws_lambda_powertools.utilities.data_masking import DataMasking
from aws_lambda_powertools.utilities.data_masking.exceptions import DataMaskingError
data_masker = DataMasking()
try:
masked = data_masker.erase(
{"customer": {"email": "[email protected]"}},
masking_rules={"customer.email": {"regex_pattern": "[", "mask_format": "*"}},
)
except DataMaskingError:
# Stop processing the payload when masking cannot be completed.
raise

Missing fields continue to follow the existing raise_on_missing_field setting. With its default value, a missing field raises DataMaskingFieldNotFoundError; when explicitly disabled, Data Masking emits a warning and continues.

See #8446 for the complete change.

Faster Parser imports

Importing parse or event_parser previously loaded all 16 Parser envelope modules, even when the application did not use an envelope.

Envelopes and BaseEnvelope are now loaded only when first accessed. Existing public imports continue to work, so no application changes are required.

In the Lambda benchmark contributed in #8405, this reduced INIT_DURATION by approximately 900ms on arm64 with Python 3.13 and 1024MB of memory. The exact improvement depends on the function and packaging configuration.

Thank you @​ErezMizrahi for finding this and working through the compatibility details with us.

Mypy 2.2

We've just uploaded mypy 2.2.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>

7.16.1

Version 7.16.1 — 2026-09-13

• Fix: when the body of an irrefutable case (like case _:) is entirely excluded, the case line is now excluded too, just as an excluded else: body removes the else: line. Previously the case line was left behind and reported as missing. Closes issue 1563 with pull 2269.
• Fix: using CoverageData.update() twice on an in-memory database would fail, as described in issue 2279. This is now fixed.

7.16.0

Version 7.16.0 — 2026-08-28

• When combining files, now path separator slashes will automatically be converted to the local file system style. This makes it less necessary to define [paths] configuration to combine data across operating systems. Fixes issue 2266.
• The Coverage.switch_context() method now returns the previous context.
• Fix: previously, a [paths] pattern would be replaced everywhere in a file path when it was only meant to be replaced once, in the leading portion of the path. This is now fixed, in pull 2268.
• Fixes to validation of options and configuration settings:
  • Negative precision settings now always cause useful error messages (pull 2261).
  • An invalid regex in the --contexts option (or the [report] contexts setting) reported a confusing “Couldn’t use data file …: user-defined function raised exception” error. Now it raises a proper configuration error naming the bad regex, like other regex settings do (pull 2262).
  • Non-string values in TOML configuration settings now produce a helpful error message instead of a traceback. This affects list settings whose elements aren’t strings (like omit, exclude_lines, or a [paths] entry), file settings like data_file, and any wrong-typed value in the [paths] section (pull 2263).
  • coverage run refuses run-affecting command-line options like --branch alongside --concurrency=multiprocessing, since they can’t reach the subprocesses. The check only recognized multiprocessing as the entire option value, so --concurrency=multiprocessing,thread slipped through and failed later with “Can’t combine statement coverage data with branch data”. Each named concurrency library is now properly considered (pull 2270).
• Fix: coverage annotate -d DIR raised an AssertionError if any measured file had an extension other than .py, such as a .pyw file on Windows. The original extension is now restored on the annotated copy (pull 2265).

Sourced from tox's changelog.

Bug fixes - 4.64.2

• A tox environment with env_dir = "{tox_root}/.venv" no longer crashes with FileExistsError after another environment ran (:issue:4090) - by :user:gaborbernat.

  • With :ref:venv_redirect unset, the new default, tox writes the redirect file unless a tox environment lives at .venv; with true, tox fails the run with an error naming that environment.
  • tox deletes a redirect file it wrote where an environment should live, and fails the environment with an error naming any other file there. (:issue:4091)

• The :PEP:832 .venv redirect file now names a deliberate development environment - by :user:gaborbernat.

  • tox picks :ref:venv_redirect_env, else an environment named dev, else the first that installs the project in development mode, and writes nothing without one, so a project that uses tox for tests alone gets no file.
  • tox devenv points the redirect at the environment it creates, and later runs leave it in place.
  • tox tells virtualenv to write no redirect file of its own beside the environments it builds. (:issue:4092)

Bug fixes - 4.64.1

• Apply -x/--override and TOX_OVERRIDE values that target a section the configuration file does not define, such as tox.skip_missing_interpreters on a tox.ini without a [tox] section, instead of dropping them - by :user:gaborbernat. (:issue:4089)

v4.64.0 (2026-09-24)

Features - 4.64.0

• Point a :PEP:832 .venv redirect file at a tox environment after each run, so editors such as VS Code or PyCharm pick it as the project interpreter instead of asking you for a path under .tox - by :user:gaborbernat.

  • tox picks an environment named dev, then one installing the project in development mode, then the first of :ref:env_list; set :ref:venv_redirect_env to choose another.
  • tox leaves a .venv directory alone, and a redirect file pointing outside its environments.
  • tox removes the redirect while it recreates the target and writes it back once the run ends.
  • Set :ref:venv_redirect to false to opt out.
  • The feature is provisional while :PEP:832 is a draft: a minor or patch release may change it in backward incompatible ways to follow the PEP. (:issue:4013)
