Jun 1, 2025June 2025 – Delivered targeted reliability and traceability improvements in the awslabs/landing-zone-accelerator-on-aws repository. Implemented selective skip for bulk updates of CloudWatch Logs subscription filters to prevent configuration drift across accounts, regions, and organizational units. Enhanced gateway association metadata in the network VPC stack to capture VPC name, route table name, and association type for improved debugging and traceability. Fixed critical metadata lookup for route entries in V1 stacks to ensure correct handling of standard and prefix-list routes. Guarded against undefined destinationsConfig.s3 when accessing overrideS3LogPath in VPC flow logs to eliminate runtime errors. Documentation updates accompany the changes for clearer guidance. These efforts reduce drift, improve operational reliability, and strengthen debugging capabilities across networking and logging components.

Jan 1, 2025January 2025: Focused improvements on data integrity for mapping uploads in the awslabs/landing-zone-accelerator-on-aws repo. Delivered a configuration-driven validation that ensures mappings only include LZA-enabled accounts and regions, aligning with the accounts config and reducing invalid/unsupported mappings. This strengthens the reliability of the Landing Zone Accelerator onboarding flow and safeguards downstream provisioning.

Dec 1, 2024Month: 2024-12 — Security hardening and reliability improvements in the awslabs/landing-zone-accelerator-on-aws repository. Key activity this month was a targeted bug fix for the CloudWatch Logs CMK integration: corrected the conditional check by renaming the variable from isLambdaCMKEnabled to isCloudWatchLogsGroupCMKEnabled in the KMS key resource logic to ensure CMK is enabled for CloudWatch Logs as intended. No new features were shipped this month; the work strengthens encryption coverage, reduces misconfiguration risk, and enhances operational resilience for CloudWatch Logs data.
