Bug Fixes
Security Group Handling for V2 Network Stacks
This release resolves a critical issue where security groups associated with RAM-shared subnets were unintentionally deleted during the networking v1-to-v2 stack upgrade (enabled via useV2Stacks: true). The root cause was a shared createSecurityGroups function used by both the NetworkVpcStack and NetworkAssociationsStack, which performed a resourceExists() lookup to determine resource ownership during the v1→v2 migration. However, because NetworkAssociationsStack templates are never downloaded by GetCloudFormationTemplatesModule, the lookup incorrectly returned false, causing the v1 stack to remove the security group under the assumption that v2 owned it — while the v2 stack never recreated it, resulting in deletion. The fix introduces a dedicated createSecurityGroupsForSharedVpcs method for the NetworkAssociationsStack that bypasses the template lookup entirely, ensuring security groups for RAM-shared subnets are always created unconditionally.
GovCloud Account Vending Template Output Bucket
We've resolved an issue where the build script for the GovCloud Account Vending Service Catalog product did not correctly set the template output bucket. The TEMPLATE_OUTPUT_BUCKET variable is now properly defaulted when not present in the environment, ensuring that the GovCloud account vending product templates are published to the correct S3 location during the build process.
