Bumps pip from 26.0.1 to 26.1.

Changelog

Sourced from pip's changelog.

26.1 (2026-04-26)

Deprecations and Removals

  • Drop support for Python 3.9. ([#13795](https://github.com/pypa/pip/issues/13795) <https://github.com/pypa/pip/issues/13795>_)

Features

  • Add experimental support to read requirements from standardized pylock.toml files (-r pylock.toml). ([#13876](https://github.com/pypa/pip/issues/13876) <https://github.com/pypa/pip/issues/13876>_)
  • Allow --uploaded-prior-to to accept a duration in days (e.g., P3D for 3 days ago). ([#13674](https://github.com/pypa/pip/issues/13674) <https://github.com/pypa/pip/issues/13674>_)

Enhancements

  • Speed up dependency resolution when there are complex conflicts. ([#13859](https://github.com/pypa/pip/issues/13859) <https://github.com/pypa/pip/issues/13859>_)
  • Reduce memory usage when resolving large dependency trees. ([#13843](https://github.com/pypa/pip/issues/13843) <https://github.com/pypa/pip/issues/13843>_)
  • Emit a deprecation warning when pip imports an unexpected module after installation of a distribution has started. ([#13912](https://github.com/pypa/pip/issues/13912) <https://github.com/pypa/pip/issues/13912>_)
  • Allow URL constraints to apply to requirements with extras. ([#12018](https://github.com/pypa/pip/issues/12018) <https://github.com/pypa/pip/issues/12018>_)
  • Allow unpinned requirements to use hashes from constraints. Constraints like {name}=={version} --hash=... feeds into hash verification for a corresponding requirement. ([#9243](https://github.com/pypa/pip/issues/9243) <https://github.com/pypa/pip/issues/9243>_)
  • Improve conflict reports that involve direct URLs. ([#13932](https://github.com/pypa/pip/issues/13932) <https://github.com/pypa/pip/issues/13932>_)
  • Show all errors instead of first error for faulty dependency_groups definitions. ([#13917](https://github.com/pypa/pip/issues/13917) <https://github.com/pypa/pip/issues/13917>_)

Bug Fixes

  • Fix recovery hint for missing RECORD file to use --ignore-installed instead of --force-reinstall. ([#12645](https://github.com/pypa/pip/issues/12645) <https://github.com/pypa/pip/issues/12645>_)
  • Fix misleading error message when a constraint file cannot be opened. ([#13226](https://github.com/pypa/pip/issues/13226) <https://github.com/pypa/pip/issues/13226>_)
  • Show the filename rather than the full URL when downloading files from non-PyPI indexes in non-verbose mode. ([#13494](https://github.com/pypa/pip/issues/13494) <https://github.com/pypa/pip/issues/13494>_)
  • Remove the adjacent __pycache__ directory when a .py file is removed. ([#13725](https://github.com/pypa/pip/issues/13725) <https://github.com/pypa/pip/issues/13725>_)
  • Force UTF-8 encoding for :pep:723 metadata. ([#13861](https://github.com/pypa/pip/issues/13861) <https://github.com/pypa/pip/issues/13861>_)
  • Minor performance improvement when filtering candidates during resolution. ([#13916](https://github.com/pypa/pip/issues/13916) <https://github.com/pypa/pip/issues/13916>_)
  • Fix a hang on Windows when stdout is closed during verbose output. ([#13927](https://github.com/pypa/pip/issues/13927) <https://github.com/pypa/pip/issues/13927>_)
  • Common path prefixes are determined by path segment, not character by character. ([#13847](https://github.com/pypa/pip/issues/13847) <https://github.com/pypa/pip/issues/13847>_)
  • Fix installing .tar.gz source distributions that look like a zip file. ([#13867](https://github.com/pypa/pip/issues/13867) <https://github.com/pypa/pip/issues/13867>_)

LGTM! Clean dependency update with performance improvements and security fixes.

[RISK ASSESSMENT]
🟢 LOW - Routine pip version bump (26.0.1 → 26.1) with:

  • Performance improvements (faster resolution, reduced memory)
  • Security updates (certifi, packaging, requests, urllib3, tomli)
  • Upload date (2026-04-26) is 12 days old, beyond the 7-day freshness guardrail ✅
  • No agent behavior impact (infrastructure dependency)
  • Python 3.9 drop is not a concern (project uses Python 3.13)

VERDICT:
✅ Worth merging

✅ QA Report: PASS

Dependency update verified successfully. pip 26.1 installs correctly, SDK functionality confirmed working, and all CI checks pass.

Does this PR achieve its stated goal?

Yes. This PR successfully updates the pip dependency from version 26.0.1 to 26.1 in the uv.lock file. The SDK continues to work correctly with the new pip version. All dependency installation operations complete without errors, SDK imports and object instantiation work as expected, and pip's core functionality (version check, list, show, dependency resolution) operates correctly. The update introduces performance improvements and bug fixes from pip 26.1 without introducing any breaking changes for this project.

Phase Result
Environment Setup ✅ Successfully synced 233 packages with pip 26.1
CI Status ✅ All checks passing (build, tests, pre-commit, linting)
Functional Verification ✅ SDK + pip 26.1 compatibility confirmed
Functional Verification

Test 1: Verify pip version update

Step 1 — Check the lockfile change:
Inspected uv.lock to confirm the dependency bump:

$ grep -A 3 'name = "pip"' uv.lock
name = "pip"
version = "26.1"
source = { registry = "https://pypi.org/simple" }

This confirms the lockfile was updated from pip 26.0.1 to 26.1 as intended.

Step 2 — Install dependencies with new pip version:
Ran dependency sync to install pip 26.1:

$ uv sync --frozen
Using CPython 3.13.13
Creating virtual environment at: .venv
Prepared 233 packages in 5.59s
Installed 233 packages in 410ms
 + pip==26.1
 + [232 other packages...]

All packages installed successfully without errors, confirming pip 26.1 works with the project's dependency tree.

Step 3 — Verify pip 26.1 is active:
Confirmed the new version is installed:

$ pip --version
pip 26.1 from /home/runner/.../site-packages/pip (python 3.13)

$ pip show pip | grep Version
Version: 26.1

This shows pip 26.1 is correctly installed and active in the virtual environment.


Test 2: SDK compatibility check

Step 1 — Test SDK imports:
Created and ran a test script to verify core SDK functionality:

from openhands.sdk import LLM, Agent, Conversation, Tool
from openhands.tools.file_editor import FileEditorTool
from openhands.tools.terminal import TerminalTool
from openhands.tools.task_tracker import TaskTrackerTool

Result:

✓ All imports successful

All SDK modules import without errors, confirming no import-time issues with pip 26.1.

Step 2 — Test SDK instantiation:
Verified SDK objects can be created:

llm = LLM(model="anthropic/claude-sonnet-4-5-20250929", api_key="test-key")
agent = Agent(llm=llm, tools=[Tool(name=TerminalTool.name)])

Result:

✓ LLM instantiated
✓ Agent instantiated

SDK core objects instantiate correctly with pip 26.1 in the environment.

Step 3 — Test pip operations:
Verified pip's core functionality:

$ pip list --format=json  # Returns package list successfully
$ pip show pip  # Returns package metadata successfully
$ pip install --dry-run requests  # Dependency resolution works correctly

Result:

✓ pip list command works
✓ pip 26.1 confirmed

All pip operations execute successfully, confirming the new version's functionality.


Test 3: CI validation

Checked PR CI status:

$ gh pr checks 3125
✓ sdk-tests (pass)
✓ tools-tests (pass)
✓ agent-server-tests (pass)
✓ cross-tests (pass)
✓ windows-tests (pass)
✓ pre-commit (pass)
✓ build-binary-and-test (macos, ubuntu) (pass)
✓ All 28 checks passing

All test suites pass with pip 26.1, confirming no regressions across platforms.

Issues Found

None. The dependency update works cleanly with no compatibility issues.
