Dependency Update Review

Package: virtualenv 20.26.6 → 20.36.1
Semver risk: Minor (20.26 → 20.36 within same major version)
Dependency type: Dev dependency (via pre-commit, in requirements-dev.txt only)
CI status: Passing (linting + Python unit tests)

Changelog Analysis

Sources consulted:

Breaking changes: None found. All releases remain in the 20.x series with backward-compatible changes.

Security fixes:

  • v20.36.1: Fix TOCTOU vulnerabilities in app_data and lock directory creation that could be exploited via symlink attacks (#3013)
  • v20.36.0: Updated filelock dependency to 3.20.1 to fix CVE-2025-68146 (#3002)

Notable changes across 10 minor releases (20.27.0 → 20.36.1):

  • Added Tcl/Tkinter support (v20.33.0)
  • Added PyPy 3.11 support (v20.34.0)
  • Declared Python 3.14 support (v20.35.0)
  • Added PEP 440 version specifier support for --python flag (v20.36.0)
  • Added discovery of uv-managed Python installations (v20.32.0)
  • Multiple bug fixes for cache invalidation, file descriptor leaks, Windows compatibility, and Nushell activation scripts
  • Embedded pip upgraded from 24.2 to 25.3; setuptools upgraded

Deprecations: None found.

Compatibility Assessment

  • Project uses affected APIs: No — virtualenv is used indirectly via pre-commit as a dev tool. The project does not call virtualenv APIs directly.
  • Peer dependency requirements satisfied: Yes — the only new transitive dependency note is typing-extensions which is already present in the project.
  • Code changes required: No — only requirements-dev.txt version pin change.
  • Prior attempts: No maintainer comments or prior reverts found for this upgrade.

Recommendation

APPROVE — This is a minor version bump of a dev-only dependency with no breaking changes, two security fixes, and all CI checks passing.
