v1.4.0

[1.4.0] - 2026-05-11

Added

• max_tool_iterations field on CompletionConfig (default 10) — bounds recursive tool-calling in both generate/4 and generate_stream/4; returns {:error, :max_tool_iterations_exceeded} when the limit is reached (the streaming path yields it as a stream element).
• Integration test exercising the OpenAI tool-calling round-trip (assistant tool-call → tool result → final response), backed by a shared fixture set used across all four mojentic ports.

Changed

• SimpleRecursiveAgent completion detection requires a strict whole-string match for DONE/FAIL (case-insensitive, trimmed); responses that merely contain those words as substrings no longer trigger completion.
• AsyncDispatcher documents that agents matching an event are dispatched concurrently via Tasks — intentional and safe under the BEAM's process isolation; SharedWorkingMemory carries a corresponding note about why that safety holds.

Fixed

• AsyncDispatcher.wait_for_empty_queue could observe an empty queue while agent tasks were still processing events that would enqueue follow-up events; that window is now closed.
• Asynchronous event-handler crashes in SimpleRecursiveAgent were swallowed, leaving solve/2 to hang; handler errors now surface via a HandlerErrorEvent.
