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 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 rewrote Copilot’s 800,000-line agent runtime in Rust with agents doing most of the coding
The useful part is not the 800,000-line headline. GitHub has published unusually detailed receipts for a production-scale agent-assisted migration: roughly $120,000 of token spend, 14.5 weeks of incremental releases, dozens of regressions, extensive compatibility tests and a workload-specific jump from 7.55 to 120 session lifecycles per second.
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 Copilot Auto now lets developers choose whether routing optimizes for cost or intelligence
The material change is that model routing is no longer a single opaque optimization target. Developers can now tell Copilot whether to bias Auto toward lower cost, a middle ground or higher quality while GitHub still chooses a model prompt by prompt.
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 Enterprise Server 3.22 brings Copilot CLI into disconnected and air-gapped environments
The technical-preview feature separates Copilot CLI from GitHub Cloud for core coding, shell and repository workflows, giving regulated and isolated environments a supported agent path while leaving cloud-dependent capabilities such as GitHub-hosted model selection and web search unavailable.
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 Copilot is moving enterprise seats to upfront billing and longer chat retention
From September and October, Copilot Business and Enterprise seat access becomes more tightly coupled to upfront payment. A separate September 28 policy migration enables a unified Copilot experience by default, retains github.com chat data for the life of the account and changes code review’s default effort from Lite to Balanced.
GitHub Copilot turns Slack and Teams conversations into shared coding-agent sessions
GitHub Copilot can now turn Slack or Teams threads into collaborative cloud-agent sessions. Teammates can add context and steer the work in public, while repository permissions, agent budgets and optional extra PR approvals remain the main control boundaries.
RevenueCat's 4,964-app study finds Black Friday offers lift sign-ups — not necessarily customer value
Holiday subscription offers correlate with more payers, but lower revenue per buyer and substantial selection bias complicate the economics. Christmas-only offers show no clear advantage.
