June 2025 development focus concentrated on feature delivery, stability improvements, and release engineering across containers/ramalama and containers/qm. Key release work included bumping versions to v0.9.x and v0.10.0 across release artifacts to streamline customer-facing updates. Major stability fixes addressed llama-stack container builds, generation handling, container lifecycle (stop by name), and robust error handling (OCI without engine). New capabilities were introduced (multi-modal support, ramalama chat command, user-specified image handling, and live llama-stack URL visibility) plus improvements to demo scripts for serving. Testing and build isolation were strengthened with improved test infra, disk-space optimizations for image builds, and a dedicated VM for builds. Security and compatibility improvements were pursued via SELinux policy refinements for qm and llama-stack compatibility fixes.
