GitHub Actions adds workflow lockfiles that pin transitive dependencies
GitHub's October 14 editor's correction confirms Actions workflow lockfiles are available on Free and Team as well as Enterprise Cloud—not enterprise-only as initially reported.

GitHub makes enterprise licence compliance a pull-request merge gate — with an API for coding agents
A new GitHub ruleset can stop unapproved dependency licences at merge time, and agents can check packages before recommending them.
GitHub Apps gain narrow repository-creation permissions and safer installation automation
GitHub Apps no longer need repository-administration permission just to create repositories. New fine-grained installation controls and token-rotation support reduce the privilege required for integration automation.
GitHub makes stacked pull requests a native production workflow
Stacked pull requests are now generally available on GitHub. The shift matters as coding agents make large changes faster than humans can safely review them: teams can keep one coherent change dependency-ordered while reviewing it as smaller PRs.
GitHub adds credential inventory to its selective incident-response kill switches
GitHub’s credential-response story now has both discovery and containment: enterprise owners can export SSH keys, PATs, OAuth and GitHub App tokens with ownership, scope and last-use metadata, then use selective revocation rather than invalidating every credential a user holds.
GitHub Actions can now block who or what starts a workflow — and `pull_request_target` is getting a secure default
GitHub Actions now has enforceable actor and event rules before a workflow starts, plus a coming default block for a trigger that can expose repository secrets to untrusted fork code.
GitHub Actions is moving `ubuntu-latest` to Ubuntu 26.04 — test before October 19
GitHub-hosted Actions jobs that use `ubuntu-latest` are about to change operating-system generation without a YAML edit; teams can test on `ubuntu-26.04` now or pin 24.04 while they migrate.
GitHub AI Scan no longer needs CodeQL default setup
The scanner itself is not the new part. The September 16 change removes the CodeQL-default-setup gate that GitHub’s July rollout originally required, making AI-assisted vulnerability detection easier to add to repositories with different code-scanning configurations.
GitHub has switched off SHA-1 HTTPS support — old Git and API clients can now fail
The deadline is no longer theoretical: browsers, Git HTTPS backends and API clients that still depend on SHA-1-era TLS algorithms can now lose connectivity to GitHub.com.
GitHub Spark is shutting down August 31 — export code now and replace broken `llm()` calls
GitHub Spark stops being available to existing users on August 31, 2026. Deployed apps are meant to keep running, but owners should export code to a repository now; Spark apps using `llm()` need a separate inference provider because the underlying GitHub Models service retired July 30.
GitHub Actions makes cache access a least-privilege workflow permission
The change turns cache poisoning from mostly a workflow-design warning into an enforceable permission boundary. Teams can let untrusted jobs restore caches without writing them, prevent reusable workflows from escalating cache access and isolate jobs that only need to publish cache entries.
GitHub can now make unresolved secret leaks a hard pull-request merge blocker
The useful change is where enforcement happens. Teams can now make unresolved leaked credentials a branch-policy failure, with organization and enterprise rollout plus API configuration for large repository fleets.
GitHub Actions is starting runtime brownouts for outdated self-hosted runners
Teams with pinned, custom-image or auto-update-disabled GitHub Actions runners can now see registration or job execution fail before the September 25 cutoff. The migration is not just a one-time jump to v2.329.0: already-registered runners must also stay within 30 days of the latest runner release.
GitHub restores repository star-history analytics without exposing individual stargazers
Repository growth tools can measure when star counts changed again without rebuilding individual-user histories. The new API deliberately separates aggregate popularity data from stargazer identity, so integrations need to distinguish trend analytics from user-level community data.
GitHub CLI’s Linux package signing key expires September 5
The CLI itself is not being deprecated. The risk is narrower and operational: stale Linux repository keyrings can stop package installs or updates from verifying after the old signing key expires.
GitHub’s OAuth apps get short-lived tokens, multiple callbacks — and a wildcard setting worth auditing
GitHub OAuth apps can now use eight-hour access tokens with rotating refresh tokens, register up to 10 callback URLs, and explicitly control wildcard callback matching. New apps default to expiring tokens, while existing single-callback apps should review a legacy wildcard setting GitHub has now made visible.
GitHub is turning agent confidence into a workflow control for Issues
GitHub Issues now gives agent automations confidence levels, rationales and optional approvals, letting teams automate routine triage while holding uncertain changes for review.
Bitwarden moves app-store clients to a commercial licence while keeping GPL builds on GitHub
Bitwarden is changing which client binaries it distributes through app stores, not retroactively relicensing GPL code. Self-hosters and downstream redistributors should distinguish current compatibility from future feature divergence.
VS Code’s Agent Host can now run Dev Container sessions on remote SSH, Tunnel and WSL projects
The Agent Host’s environment boundary has moved from local Dev Containers to remote development hosts, making persistent coding-agent sessions more portable across real remote projects.
Agent Plugins 1.0 now has a concrete cross-client compatibility layer for Skills and MCP
Agent Plugins 1.0 now has documented support across VS Code, Cursor, GitHub Copilot, ChatGPT/Codex, Kiro and several open-source agents. That makes the format materially more useful for cross-client distribution, but portable components remain limited to Agent Skills and MCP servers while permissions, hooks, commands and host UX stay client-specific.
