GitHub has announced significant upgrades to its Actions platform, enhancing performance and flexibility for developers. New features include YAML anchors and expanded caching.

GitHub has unveiled a comprehensive overhaul of its Actions platform, focusing on enhancing performance, workflow flexibility, and reliability, according to a recent announcement by Ben De St Paer-Gotch, Director of Product at GitHub. The improvements are a response to the platform’s massive growth and user demand for faster builds and better security.

Core Architecture Rebuild

In 2025 alone, developers utilized 11.5 billion GitHub Actions minutes, marking a 35% increase from 2024. To accommodate this growth, GitHub has re-architected the core backend services powering its Actions platform. This effort, which began in early 2024, has significantly improved the platform’s scalability and feature delivery, now supporting 71 million jobs daily. This transformation enhances uptime, resilience, and performance while reducing internal throttles.

New Features and Improvements

Among the notable upgrades is the introduction of YAML anchors, a highly requested feature that reduces duplication by allowing developers to define settings once and reference them elsewhere in their workflows. Additionally, GitHub has released non-public workflow templates and increased the depth of reusable workflows, allowing for more modular and scalable CI/CD pipelines.

The platform also now supports larger caches exceeding the previous 10GB limit, addressing a major pain point for projects with extensive dependencies. Furthermore, the number of workflow dispatch inputs has been increased from 10 to 25, providing developers with greater flexibility in building automation workflows.

Future Roadmap and Community Involvement

Looking ahead to 2026, GitHub plans to introduce support for timezones in scheduled jobs and improvements to schedule reliability, alongside other enhancements based on community feedback. The company is actively seeking input from users to shape the future of GitHub Actions, encouraging participation in community discussions to prioritize quality-of-life improvements.

These developments underscore GitHub’s commitment to refining its Actions platform, ensuring it meets the evolving needs of the developer community. For more details, visit the official announcement on the GitHub blog.
