## Summary
- Adds top-level `permissions: contents: read` to 5 workflows that only
had job-level permissions: `pr_labeler_file`, `pr_labeler_title`,
`tag-external-contributions`, `v03_api_doc_build`,
`auto-label-by-package`
- SHA-pins all 14 third-party actions to full commit SHAs to prevent
supply chain attacks via tag hijacking
## Why
**Missing top-level permissions:** Without an explicit top-level
`permissions` block, workflows inherit the repository/org default token
permissions, which may be overly broad. Adding `contents: read` as the
default restricts the blast radius if a dependency or action step is
compromised.
**SHA pinning:** Mutable tags (`@v1`, `@master`) can be force-pushed by
the action maintainer or an attacker who compromises their account.
Pinning to a full 40-character SHA ensures the exact reviewed code
always runs. Tag comments are preserved for readability.
### Actions pinned
| Action | File(s) |
|--------|---------|
| `pypa/gh-action-pypi-publish` | `_release.yml` (2 uses) |
| `ncipollo/release-action` | `_release.yml` |
| `Ana06/get-changed-files` | `check_diffs.yml` |
| `astral-sh/setup-uv` | `check_diffs.yml`, `uv_setup/action.yml` |
| `CodSpeedHQ/action` | `check_diffs.yml` |
| `google-github-actions/auth` | `integration_tests.yml` |
| `aws-actions/configure-aws-credentials` | `integration_tests.yml` |
| `amannn/action-semantic-pull-request` | `pr_lint.yml` |
| `bcoe/conventional-release-labels` | `pr_labeler_title.yml` |
| `mikefarah/yq` | `v03_api_doc_build.yml` |
| `EndBug/add-and-commit` | `v03_api_doc_build.yml` |
| `peter-evans/create-pull-request` | `refresh_model_profiles.yml` |
## Test plan
- [x] CI passes — all workflows still resolve their actions correctly
- [x] Verify no functional change: SHA refs point to the same code as
the previous tags

<blockquote>
<h2>v7.0.0</h2>
<h2>v7 What's new</h2>
<h3>Direct Uploads</h3>
<p>Adds support for uploading single files directly (unzipped). Callers
can set the new <code>archive</code> parameter to <code>false</code> to
skip zipping the file during upload. Right now, we only support single
files. The action will fail if the glob passed resolves to multiple
files. The <code>name</code> parameter is also ignored with this
setting. Instead, the name of the artifact will be the name of the
uploaded file.</p>
<h3>ESM</h3>
<p>To support new versions of the <code>@actions/*</code> packages,
we've upgraded the package to ESM.</p>

<blockquote>
<h2>v8.0.0</h2>
<h2>v8 - What's new</h2>
<h3>Direct downloads</h3>
<p>To support direct uploads in <code>actions/upload-artifact</code>,
the action will no longer attempt to unzip all downloaded files.
Instead, the action checks the <code>Content-Type</code> header ahead of
unzipping and skips non-zipped files. Callers wishing to download a
zipped file as-is can also set the new <code>skip-decompress</code>
parameter to <code>false</code>.</p>
<h3>Enforced checks (breaking)</h3>
<p>A previous release introduced digest checks on the download. If a
download hash didn't match the expected hash from the server, the action
would log a warning. Callers can now configure the behavior on mismatch
with the <code>digest-mismatch</code> parameter. To be secure by
default, we are now defaulting the behavior to <code>error</code> which
will fail the workflow run.</p>
<h3>ESM</h3>
<p>To support new versions of the @actions/* packages, we've upgraded
the package to ESM.</p>

- GitHub releases have not been created for partner package releases
since #34784 (Jan 16). PyPI publishes were unaffected.
#34784 added `test-dependents` to the `publish` job's dependency chain.
`test-dependents` only runs for core/langchain releases, so it's skipped
for everything else. `publish` handles this with `if: ${{ !cancelled()
&& !failure() }}`, but `mark-release` (which creates the GitHub release)
doesn't have the same guard — so GitHub Actions skips it whenever
`test-dependents` is skipped.
## Missing GitHub releases
`langchain-xai==1.2.2`, `langchain-standard-tests==1.1.3`,
`langchain-groq==1.1.2`, `langchain-anthropic==1.3.2`,
`langchain-standard-tests==1.1.4`, `langchain-openai==1.1.8`,
`langchain-openai==1.1.9`, `langchain-anthropic==1.3.3`,
`langchain-openrouter==0.0.2`
`deepagents` requires Python >= 3.11. Note: this won't display in the
action title in the UI if requesting 3.10, and it will also still show
`(3.10, 3.13)` since that's what the integration packages are testing
against. `deepagents` matrix title will be accurate.
Add testing for `deepagents` both (1) on scheduled interval and (2)
release of `langchain-core` or `langchain` to ensure compatibility.
Should catch breaking changes early.

To accommodate breaking changes (e.g., removal of deprecated params like
`callback_manager`).
Will revert once we have updated releases of anthropic and openai.
Mostly adding a descriptive frontmatter to workflow files. Also address
some formatting and outdated artifacts
No functional changes outside of
[d5457c3](d5457c39ee),
[90708a0](90708a0d99),
and
[338c82d](338c82d21e)
Reusable workflows are not currently supported by PyPI's Trusted
Publishing
functionality, and are subject to breakage. Users are strongly
encouraged
to avoid using reusable workflows for Trusted Publishing until support
becomes official. Please, do not report bugs if this breaks.

<h2>v5.0.0</h2>
<h3>🚨 Breaking Change</h3>
<p>This release fixes an inconsistency in path behavior for single
artifact downloads by ID. <strong>If you're downloading single artifacts
by ID, the output path may change.</strong></p>
<h4>What Changed</h4>
<p>Previously, <strong>single artifact downloads</strong> behaved
differently depending on how you specified the artifact:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (direct)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/my-artifact/</code> (nested)</li>
</ul>
<p>Now both methods are consistent:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (unchanged)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/</code> (fixed - now direct)</li>
</ul>
<h4>Migration Guide</h4>
<h5>✅ No Action Needed If:</h5>
<ul>
<li>You download artifacts by <strong>name</strong></li>
<li>You download <strong>multiple</strong> artifacts by ID</li>
<li>You already use <code>merge-multiple: true</code> as a
workaround</li>
</ul>
<h5>⚠️ Action Required If:</h5>
<p>You download <strong>single artifacts by ID</strong> and your
workflows expect the nested directory structure.</p>
<p><strong>Before v5 (nested structure):</strong></p>
<pre lang="yaml"><code>- uses: actions/download-artifact@v4
with:
artifact-ids: 12345
path: dist
# Files were in: dist/my-artifact/
</code></pre>
<blockquote>
<p>Where <code>my-artifact</code> is the name of the artifact you
previously uploaded</p>
</blockquote>
<p><strong>To maintain old behavior (if needed):</strong></p>
<pre lang="yaml"><code></tr></table>
</code></pre>
</blockquote>

Stricter JSON schema validation broke a test. Test was fixed in
https://github.com/langchain-ai/langchain/pull/32145. Core release runs
old tests (i.e., last released version of langchain-anthropic) against
new core. So we bypass anthropic for release. Will revert after.
