Enhancement: All runners now have 150GB of disk space. This is a 50% increase from the previous 100GB.
Enhancement: Updated the Ubuntu x86-64 runners to be in sync with GitHub Actions runners release 20240225.1.1. The key changes are:
- [All OSes] Ruby versions <= 2.7.x will be removed on February, 26
- [All OSes] Go 1.19.x will be removed and 1.21.x set as default on February, 26
Fix: Introduced and fixed a bug where the local dockerhub mirror was erroring out in a few cases.

Fix: A race condition caused a small fraction of runners to terminate before the job was complete. This is not fixed.
Change: Billing for jobs is now done on a per-minute basis.

Enhancement: The product architecture has been updated to flatten and simplify the serving stack. This results in a huge improvement to the runner start time.

Enhancement: New runner types are available.
