Ray-2.58.0
Highlights Ray Serve LLM: In this release we've completed KV cache and token aware request routing, which was previewed in 2.57.

Point-in-time search , query_time is now documented on both the MCP tool and the Search API : search the index as it stood at an instant, and have relative date filters resolve against that instant rather than now. Two more search parameters , max_results caps how many results come back (1–50), and snippet_max_length caps the snippet per result.

Prompt-driven extraction , the Fetch endpoint accepts a prompt , and returns what an LLM read out of the page for that instruction instead of the whole page. Usage and overrides over MCP , every authenticated tool call now reports its cost under _meta["keenable/usage"] , and an integrator can pin the search mode with _meta["keenable/overrides"] .
