May 2025 highlights for replicatedhq/replicated: Delivered a unified SCP endpoint retrieval workflow for Virtual Machines, improving VM operations and developer experience. This work consolidates SSH/SCP endpoint retrieval into a single function, enhancing reliability and reducing duplication. Implemented new SCP endpoint command with robust error handling and added dedicated unit tests. The changes improve operational efficiency for VM management and contribute to higher quality, test-covered code in the repository.

March 2025 monthly summary for replicatedhq/platform-examples highlighting a single feature delivered and no major bugs fixed. Key accomplishments focus on simplifying the Postgres deployment configuration in gitea-chart.yaml by removing the explicit postgresql configuration when internal_postgres_enabled is '1', and relying on the postgres-ha service to handle high availability. This reduces chart complexity and options, simplifying deployments for users.
