Highlights
- Fully self-contained: the EC2 setup script is embedded in the CloudFormation template as an SSM document. One file, no external downloads at boot. Re-run setup any time with
aws ssm send-command - CodeCommit version control replaces git-remote-s3, with native CodePipeline integration and workspace recovery on instance rebuild
- Agent Toolkit for AWS built in: the AWS MCP Server and curated AWS skills are configured automatically for Kiro IDE and Kiro CLI
- Current tooling: AWS CLI v2 via the official installer, code-server 4.135.0, CodePipeline V2, .NET 10, all versions pinned and exposed as CloudFormation parameters
- Numerous security and reliability fixes, including VPC flow logs delivery, SSM agent permissions, log group lifecycle management, and tightened bucket policies
Breaking changes
GitHubBranchparameter removed (the template no longer downloads its setup script from GitHub)UvenvVersionparameter replaced byUvVersion- Redeploying with a prefix previously used by v1 may require a one-time cleanup of leftover runtime-created log groups
Upgrading from v1
v1 stacks cannot be updated in place to v2 (source control storage changed). Deploy v2 as a new stack and migrate workspace content via git. The v1 template remains available in the v1.0.0 release and requires GitHubBranch=v1 to deploy.
