v0.15.1

The workspace image is now published for arm64 as well as amd64, so an ecs-ec2 deployment can run Graviton slots on the official images. The code is identical to 0.15.0.

Improved

• The published workspace image covers arm64. An ecs-ec2 deployment can declare a Graviton slot class and run it on the image from this release; until now an operator had to build that image themselves. The control-plane image has covered both architectures since 0.11.0.

Upgrade notes

To offer Graviton slots, set the pool stack’s SlotAmiIdArm64 to the arm64 ECS-optimized AMI, then add a class with arch=arm64 to Ec2SlotTypes and pass the same AMI as Ec2SlotAmiArm64 — the control plane refuses to start when an arm64 class is declared without it. Adding a class moves nobody: Ec2DefaultSlotClass still decides where a member with no choice of their own lands. A member who does move reinstalls their home’s architecture-dependent tools on the next start, which costs them one slow start.

Coming from 0.14.x, the Python 3.11 → 3.13 note in 0.15.0 applies to this release too.

Agent CLI pins are unchanged from 0.15.0.
