Blackboard Learn vs Chamilo

Chamilo runs three lines at once. The legacy 1.11 branch takes security and bugfix releases roughly quarterly, 2.0 reached GA in April and has drawn three patch releases since, and a 3.0 line opened on 13 August. The 3.0 beta is where the direction sits: 456 changes spanning 88 plugin fixes, a 44-item security sweep, and a new MCP server with OAuth 2.1 that exposes course authoring and review to outside clients. The feed's own bodies are unreliable here - both 3.0 tags arrived carrying a single line of text, and the 2.0 GA release reached it only as scraped page fragments.

The rewrite has stopped being the story and the agent surface has started. 2.0 spent its cycle absorbing the legacy feature set - LTI, ONLYOFFICE, the plugin catalogue - and reached GA; 3.0's first beta spends most of its weight on that same restoration work but adds something no 2.0 release contains, an MCP server with OAuth 2.1 auto-connect and tools that write rather than only read. Model providers are being wired directly into the AI helper alongside it. Security remains constant across all three branches, with 44 security items in the 3.0 beta alone.

Expect the MCP tool surface to widen in the next 3.0 beta, since the first pass already moved past read-only lookups into course authoring and review. Whether 3.0 becomes the supported line or 2.0 keeps taking patches is the question the tags themselves do not answer.
