Release Notes

Fixed

  • An MCP tool whose schema escapes a character needlessly no longer fails
    the turn.
    JSON Schema's regexes are the Unicode-mode dialect, where an
    escape like \_ is an error; exa's agent_run declares
    ^agent\_run\_, and DeepSeek, which checks every pattern when the
    schema names its $schema, refused every request that carried the tool.
    iota now drops such backslashes when it lists a server's tools — the
    pattern matches the same strings — and leaves the rest of the schema,
    $schema included, as the server wrote it (X-57).
  • A job's page no longer holds up the prompt while its log grows. The
    /jobs page read the job's log on every refresh from the loop that draws
    the screen; it now reads it off that loop, once a refresh, never more than
    a fixed number of bytes, and for as long as the page is open — output from
    a command the job left running in the background still shows (X-50).
  • The host no longer shows iota idle while a job's end is still to be
    taken.
    The host's state followed the count of running jobs, so when one
    job ended as another started the count did not move: herdr, cmux or the
    terminal's progress could show iota idle before it had taken the ended
    job's notice, and a job that never started could keep it busy. Each end now
    reaches the host as its own event, in the order the jobs changed (X-50).
