Updates python-dotenv from 1.0.1 to 1.2.2

Release notes

Sourced from python-dotenv's releases.

v1.2.2

Added

• Support for Python 3.14, including the free-threaded (3.14t) build. (#)

Changed

• The dotenv run command now forwards flags directly to the specified command by @​bbc2 in theskumar/python-dotenv#607
• Improved documentation clarity regarding override behavior and the reference page.
• Updated PyPy support to version 3.11.
• Documentation for FIFO file support.
• Support for Python 3.9.

Fixed

• Improved set_key and unset_key behavior when interacting with symlinks by @​bbc2 in #790c5
• Corrected the license specifier and added missing Python 3.14 classifiers in package metadata by @​JYOuyang in theskumar/python-dotenv#590

Breaking Changes

• dotenv.set_key and dotenv.unset_key used to follow symlinks in some situations. This is no longer the case. For that behavior to be restored in all cases, follow_symlinks=True should be used.

• In the CLI, set and unset used to follow symlinks in some situations. This is no longer the case.

• dotenv.set_key, dotenv.unset_key and the CLI commands set and unset used to reset the file mode of the modified .env file to 0o600 in some situations. This is no longer the case: The original mode of the file is now preserved. Is the file needed to be created or wasn't a regular file, mode 0o600 is used.

Misc

• skip 000 permission tests for root user by @​burnout-projects in theskumar/python-dotenv#561
• Bump actions/checkout from 5 to 6 in the github-actions group by @​dependabot[bot] in theskumar/python-dotenv#593
• Add Windows testing to CI by @​bbc2 in theskumar/python-dotenv#604
• Improve workflow efficiency with best practices by @​theskumar in theskumar/python-dotenv#609
• Remove the use of sh in tests by @​bbc2 in theskumar/python-dotenv#612

New Contributors

• @​JYOuyang made their first contribution in theskumar/python-dotenv#590
• @​burnout-projects made their first contribution in theskumar/python-dotenv#561
• @​cpackham-atlnz made their first contribution in theskumar/python-dotenv#597

Updates urllib3 from 1.26.16 to 2.7.0

Release notes

Sourced from urllib3's releases.

2.7.0

🚀 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 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.

Security

Addressed high-severity security issues. Impact was limited to specific use cases detailed in the accompanying advisories; overall user exposure was estimated to be marginal.

• Decompression-bomb safeguards of the streaming API were bypassed:

  1. When HTTPResponse.drain_conn() was called after the response had been read and decompressed partially. (Reported by @​Cycloctane)
  2. During the second HTTPResponse.read(amt=N) or HTTPResponse.stream(amt=N) call when the response was decompressed using the official Brotli library. (Reported by @​kimkou2024)

  See GHSA-mf9v-mfxr-j63j for details.

• HTTP pools created using ProxyManager.connection_from_url did not strip sensitive headers specified in Retry.remove_headers_on_redirect when redirecting to a different host. (GHSA-qccp-gfcp-xxvc reported by @​christos-spearbit)

Deprecations and Removals

• Used FutureWarning instead of DeprecationWarning for better visibility of existing deprecation notices. Rescheduled the removal of deprecated features to version 3.0. (urllib3/urllib3#3763)
• Removed support for end-of-life Python 3.9. (urllib3/urllib3#3720)
• Removed support for end-of-life PyPy3.10. (urllib3/urllib3#4979)
• Bumped the minimum supported pyOpenSSL version to 19.0.0. (urllib3/urllib3#3777)

Bugfixes

• Fixed a bug where HTTPResponse.read(amt=None) was ignoring decompressed data buffered from previous partial reads. (urllib3/urllib3#3636)
• Fixed a bug where HTTPResponse.read() could cache only part of the response after a partial read when cache_content=True. (urllib3/urllib3#4967)
• Fixed HTTPResponse.stream() and HTTPResponse.read_chunked() to handle amt=0. (urllib3/urllib3#3793)
• Updated _TYPE_BODY type alias to include missing Iterable[str], matching the documented and runtime behavior of chunked request bodies. (urllib3/urllib3#3798)
• Fixed LocationParseError when paths resembling schemeless URIs were passed to HTTPConnectionPool.urlopen(). (urllib3/urllib3#3352)
• Fixed BaseHTTPResponse.readinto() type annotation to accept memoryview in addition to bytearray, matching the io.RawIOBase.readinto contract and enabling use with io.BufferedReader without type errors. (urllib3/urllib3#3764)

Changes

• Fixed a security issue where decompression-bomb safeguards of the streaming API were bypassed when HTTP redirects were followed. (CVE-2026-21441 reported by @​D47A, 8.9 High, GHSA-38jv-5279-wg99)
• Started treating Retry-After times greater than 6 hours as 6 hours by default. (urllib3/urllib3#3743)
• Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten. (urllib3/urllib3#3752)
