February 2026 Changelog

Here is everything that shipped in February.

Scoped Memory (Memory v2)

Agents now support three memory scopes: user, session, and agent. Context persists automatically across runs with zero configuration. Vector search queries all three scopes simultaneously.

Read the full announcement: Introducing Memory v2.

Parallel Tool Execution

The runtime now detects independent tool calls within a single step and executes them in parallel. Average speedup on fan-out workflows is 2.8x. No configuration required — the runtime infers independence from the execution graph.

New Trace Timeline UI

The trace viewer has been redesigned. The new timeline view shows steps horizontally with parallel branches visible as stacked lanes. Each step displays model, tokens, cost, and latency inline. Click any step to expand the full prompt and response.

8 New Built-in Tools

• Linear — create and update issues, query projects

• Notion — read and write pages, query databases

• Jira — create tickets, update status, query boards

• HubSpot — create and update contacts, log activities

• Twilio — send SMS, make calls, check delivery status

• SendGrid — send emails, manage templates

• Snowflake — query tables, describe schemas

• BigQuery — run queries, export results

All tools include typed inputs and outputs with auto-generated schemas.

Runtime Improvements

• Retry backoff is now configurable per tool (previously global only)

• Agent runs now support a timeout field at the run level (previously step-level only)

• The interruptOn config now accepts regex patterns for flexible matching

Bug Fixes

• Fixed a race condition in parallel tool execution that could cause duplicate tool calls under high concurrency

• Fixed memory TTL not being respected when using the Redis backend

• Fixed trace export missing the final step when the agent run was interrupted

• Fixed cost attribution double-counting retried model calls

Breaking Changes

None.
