Jun 1, 2025June 2025 monthly summary for DSD-DBS/capella-collab-manager: Key feature delivered and bug fixed: Migration of Frontend Validation Library from Zod to Valibot to reduce bundle size and prevent session history corruption. This change replaces Zod with Valibot in the frontend validation pipeline, decreasing bundle size and ensuring invalid session history data is reset rather than permanently corrupted. Commit 4505707f1e14403e53a197ff913f968279eeaae6 implemented the refactor, with accompanying validation updates.

Mar 1, 2025March 2025 monthly summary for capella-collab-manager: Consolidated three work streams—Personal Access Tokens, Session Management, and Platform tooling—into deliverable improvements that boost security governance, external integrations, and developer productivity. Key outcomes include a reusable TokenCardComponent with an admin token overview, UX enhancements and URL-driven session cookies for external clients, and a modernized build pipeline (Vite) with updated dependencies and CI fixes, plus diagram data caching to improve client performance. These efforts reduce maintenance costs, shorten release cycles, and strengthen cross-system workflows.
