Copilot code review adds enterprise governance controls
GitHub added organization runner controls and Copilot content exclusion for Copilot code review. GitHub also removed the character limit on repository custom instructions for Copilot code review.
- Security teams can exclude sensitive repos or paths from AI analysis to reduce exposure of regulated code and secrets during automated reviews.
- Platform owners can choose where code review jobs run via organization runner controls, which supports performance tuning and keeping workloads on approved infrastructure (including EU-hosted runners).
- Engineering enablement teams can encode longer, organization-specific secure coding and compliance guidance in repository custom instructions to standardize reviews across teams.

Copilot C++ modernization agent exits preview in VS 2026
Microsoft shipped GitHub Copilot modernization for C++ as generally available in Visual Studio 2026 version 18.7. The @Modernize agent assesses a solution, plans an upgrade, and executes and validates migrations for MSBuild and CMake projects.
- Application owners can reduce risk when moving legacy C++ solutions to newer MSVC Build Tools by using an agent-driven plan-and-validate workflow instead of ad-hoc manual upgrades.
- Delivery leaders can cut engineering time spent on toolchain migrations and focus effort on regressions and business-critical tests, which is often the cost driver in large C++ estates.
- Standardizing on Visual Studio 2026 for modernization can simplify developer workstation baselines and aligns the upgrade workflow with existing enterprise IDE governance.
