Let's talk about GitHub Actions

GitHub Actions has grown massively since its release in 2018; in 2025 alone, developers used 11.5 billion GitHub Actions minutes in public and open source projects, up 35% year over year from 2024. At the same time, this has not been without its growing pains, and you’ve made clear to us what improvements matter most: faster builds, improved security, better caching, more workflow flexibility, and rock-solid reliability. … ... This was not without its share of pain; it slowed the pace of feature work and delayed progress on long-standing community requests. ... ### Larger caches for bigger projects and dependency-heavy builds Repositories can now exceed the previous 10GB cache limit, removing a long-standing pain point for teams with large dependencies or multi-language monorepos. For teams with larger codebases or complex build pipelines, the old 10GB GitHub Actions cache limit often meant build dependencies were evicted before they could speed up your next workflow run, leading to repeated downloads and slower builds. This release was only possible due to our architecture rework and fulfills a request from the community, particularly among some of our largest users. … ### More performance and platform improvements shipped in 2025 We also made progress on the strong foundation laid earlier this year, including arm64-hosted runners for public repositories, macOS 15 and Windows 2025 images (now generally available), Actions Performance Metrics (also generally available), and Custom Image support in public preview. These releases are designed to improve day-to-day workflow quality and remove long-standing friction.
