Improvements:

OS Manager Tool Limits: OSManager takes tool_call_limit (default 8, per coordinator run, including delegations) and member_tool_call_limit (default 24, per specialist invocation). Explanations stay scoped to the question and grounded in the Agno docs. Set either limit to None to restore unlimited tool use, as before. See cookbook.
Cartesia Default Model: CartesiaTools now defaults to sonic-3.6. Cartesia sunsets the sonic-2 snapshots, the previous default, on October 20, 2026.

Company Routines: Editing a Product's metadata no longer unlinks its Routines. SchedulerTools and Studio can no longer delete, enable, disable or rewrite Company-managed schedules. OS Manager sends Routine and Product work to Product Manager. Under user isolation, Routines with no owner run again, and refresh archives only the caller's finished work.
Postgres Metrics: calculate_metrics() works past the driver's query parameter limit (32,765 sessions on asyncpg, 65,533 on psycopg). On AsyncPostgresDb, a failed refresh now returns an error instead of a 200 with empty metrics.
v3 Migration on Postgres: The sessions-to-runs migration streams rows through a server-side cursor. Memory is bounded by one batch, so large sessions tables no longer run out of memory.
Sandbox Checkpoints with Virtualenvs: A workspace containing a Python virtualenv no longer fails checkpoint capture on its absolute interpreter links. A checkpoint that fails because of the workspace files now ends the run with a non-retryable error and releases the session, which previously stayed stuck in finalizing.
S3 Checkpoint Cancellation: Cancelling S3CheckpointStore.aopen_archive no longer leaves the downloaded copy in scratch, and the cached-object digest check runs off the event loop.
