Updates pyparsing from 3.2.5 to 3.3.1

Changelog

Sourced from pyparsing's changelog.

Version 3.3.1 - December, 2025

  • Added license info to metadata, following PEP-639. Thanks to Gedalia Pasternak and Marc Mueller for submitted issue and PR. Fixes #626.

Version 3.3.0 - December, 2025

=========================================================================================== The version 3.3.0 release will begin emitting DeprecationWarnings for pyparsing methods that have been renamed to PEP8-compliant names (introduced in pyparsing 3.0.0, in August, 2021, with legacy names retained as aliases). In preparation, I added in pyparsing 3.2.2 a utility for finding and replacing the legacy method names with the new names. This utility is located at pyparsing/tools/cvt_pep8_names.py. This script will scan all Python files specified on the command line, and if the -u option is selected, will replace all occurrences of the old method names with the new PEP8-compliant names, updating the files in place.

Here is an example that converts all the files in the pyparsing /examples directory:

  python -m pyparsing.tools.cvt_pyparsing_pep8_names -u examples/*.py

The new names are compatible with pyparsing versions 3.0.0 and later.

  • Deprecated indentedBlock, when converted using the cvt_pyparsing_pep8_names utility, will emit UserWarnings that additional code changes will be required. This is because the new IndentedBlock class no longer requires the calling code to supply an indent stack, while adding support for nested indentation levels and grouping.

  • Deprecated locatedExpr, when converted using the cvt_pyparsing_pep8_names utility, will emit UserWarnings that additional code changes may be required. The new Located class removes the extra grouping level of the parsed values. (If the original locatedExpr parser was defined with a results name, then the extra grouping is retained, so that the results name nesting works properly; in this case, no code changes would be required.)

  • Updated all examples and test cases to use PEP8 names (unless the test case is specifically designed to test behavior of a legacy method). Added railroad diagrams for some examples.

  • Added exception handling when calling formatted_message(), so that str(exception) always returns at least something.

  • All unit tests pass with Python 3.14, including 3.14t. This does not necessarily mean that pyparsing is now thread-safe, just that when run in the free-threaded interpreter, there were no errors. None of the unit tests try to do any parsing with multiple threads - they test the basic functionality of the library, under various versions of packrat and left-recursive parsing.

Updates urllib3 from 2.5.0 to 2.6.2

Release notes

Sourced from urllib3's releases.

2.6.2

🚀 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 after a sharp decline in financial support. 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.

Changes

  • Fixed HTTPResponse.read_chunked() to properly handle leftover data in the decoder's buffer when reading compressed chunked responses. (urllib3/urllib3#3734)

2.6.1

Thank you for your support.

Changes

  • Restore previously removed HTTPResponse.getheaders() and HTTPResponse.getheader() methods. (#3731)

Thank you for your support.

Security

  • Fixed a security issue where streaming API could improperly handle highly compressed HTTP content ("decompression bombs") leading to excessive resource consumption even when a small amount of data was requested. Reading small chunks of compressed data is safer and much more efficient now. (CVE-2025-66471 reported by @​Cycloctane, 8.9 High, GHSA-2xpw-w6gg-jr37)
  • Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the Content-Encoding header, potentially leading to a denial of service (DoS) attack by exhausting system resources during decoding. The number of allowed chained encodings is now limited to 5. (CVE-2025-66418 reported by @​illia-v, 8.9 High, GHSA-gm62-xv2j-4w53)

[!IMPORTANT]

  • If urllib3 is not installed with the optional urllib3[brotli] extra, but your environment contains a Brotli/brotlicffi/brotlipy package anyway, make sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to benefit from the security fixes and avoid warnings. Prefer using urllib3[brotli] to install a compatible Brotli package automatically.
  • If you use custom decompressors, please make sure to update them to respect the changed API of urllib3.response.ContentDecoder.

Features

  • Enabled retrieval, deletion, and membership testing in HTTPHeaderDict using bytes keys. (#3653)
  • Added host and port information to string representations of HTTPConnection. (#3666)
  • Added support for Python 3.14 free-threading builds explicitly. (#3696)

Removals

  • Removed the HTTPResponse.getheaders() method in favor of HTTPResponse.headers. Removed the HTTPResponse.getheader(name, default) method in favor of HTTPResponse.headers.get(name, default). (#3622)
