### Release notes We are excited to introduce the small hosted runner on Linux Arm for GitLab.com available for the Free tier. The now available 2 vCPUs Arm runner is fully integrated with GitLab CI/CD, and will allow you to build and test your application for the ARM architecture. We are determined to provide the industry’s fastest CI/CD build speed and look forward to seeing teams achieve even shorter feedback cycles and ultimately deliver software faster. ### Problem to solve Free users want to cost-effectively build and test natively on the Arm architecture, without requiring them to setup their own self-managed runners. ### Proposal Introduce `small` hosted runner on Linux Arm for GitLab.com with the following specs | Runner Tag | vCPUs | Memory | Storage | |------------|-------|--------|---------| | saas-linux-small-arm64 | 2 | 8 GB | 30 GB | <!--triage-serverless v3 PLEASE DO NOT REMOVE THIS SECTION--> _This page may contain information related to upcoming products, features and functionality.
