New features

  • Skills load faster: the skills list fetches lightweight metadata first and loads file contents only when you open a skill.
  • The agent creation menu adds a Templates entry.
  • The remote MCP authorization screen now shows the connecting application’s name, logo, and homepage, terms, and privacy links instead of its raw client ID.
  • Slack integration available in AWS and APAC regions.

Fixes

  • Scheduled (cron) execution is restored for enterprise Fleet agents.
  • Long-running agent runs and agent-builder generations are no longer cut off after 60 seconds.
  • The Gmail read-emails tool now returns results when you search sent mail with an in:sent query.
  • Scrolling is improved for long toolbox, skill, and sub-agent lists in the agent editor, and webhook dialogs now scroll within the viewport.
