<Update label="June 15-19, 2026" rss={{ title: "2026-06-15 - Fleet product update" }}>
  ## New features

  * [Fleet tools](/langsmith/fleet/tools) now include Salesforce OAuth provider setup for self-hosted users, so you can configure the provider end to end.
  * Agent sharing is redesigned around two choices, who can use and who can edit an agent, plus a Publish as template option that lets others fork their own editable copy.
  * Fleet agents now post a notification to the originating thread, such as Slack, when they pause at a human-in-the-loop interrupt, with a link back to the agent chat.
  * You can now complete Fleet integration OAuth through your own callback URL, so headless setups can finish authentication without the LangSmith UI.
  * Agent cards now show the agent owner.
  * New first-party [templates](/langsmith/fleet/templates), Brand Copywriter and Applicant Screening, are available in the gallery.

  ## Fixes

  * Switching threads in the agent chat now clears the previous thread immediately and shows a loading state instead of stale messages.
  * The [skills](/langsmith/fleet/skills) list now degrades gracefully when one skill fails to load, so the remaining skills still appear.
</Update>

<Update label="June 8-12, 2026" rss={{ title: "2026-06-08 - Fleet product update" }}>
  ## New features

  * [Templates](/langsmith/fleet/templates) now show “by Fleet” with the Fleet logo, so curated templates match Fleet branding.

  ## Fixes

  * The Fleet list-threads endpoint now returns `items` instead of `threads`, so the response shape matches the rest of the API.
  * Fleet thread requests now return a clearer error when a large response would have triggered a 5xx, so long lists fail gracefully.
</Update>

<Update label="June 1-5, 2026" rss={{ title: "2026-06-01 - LangSmith Fleet update" }}>
  ## New features

  * [Skills](/langsmith/fleet/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](/langsmith/fleet/templates) entry.
  * The [remote MCP](/langsmith/fleet/remote-mcp-servers) authorization screen now shows the connecting application's name, logo, and homepage, terms, and privacy links instead of its raw client ID.
  * [Slack integration](/langsmith/fleet/slack-app) available in AWS and APAC regions.

  ## Fixes

  * [Scheduled (cron) execution](/langsmith/fleet/schedules) 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](/langsmith/fleet/tools) 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.
