Added

• New endpoint POST /act for executing reusable actions, inline API requests, or custom code.

Major Updates

• Membrane dashboard was fully re-designed to simplify understanding of your workspace.

  • It is now possible to connect any app (including ones found in the web or just typed-in by you) right from the dashboard.

  • Management of your connected software was refactored and simplified.

  • Added agent onboarding guides for Claude Code, Codex, Cursor, Copilot, and Windsurf

• Agentic Connection UI underwent many improvement based on usage feedback.

• Self-hosted auth no longer depends on Auth0 or any other external services.

Added

• Added workspace instance name display in workspace general setting.

• Added support for tenantKey in client JWT tokens (to replace deprecated id)

• Added flowRunsQueueSizePerConnection to workspace limits configuration

• Code sandbox jobs are now automatically re-routed when runners are over capacity - it will improve latency in some cases.

Changed

• Connector versioning now auto-determines latest version by semantic versioning on publish.

• Custom code now handles large inputs in batches with out-of-memory protection.

• Base64 encoding is now applied to Buffers in custom code JSON output - it should speed up data transfer for large custom code jobs.

Fixed

Added

• CLI telemetry events now include organization group information to provide better usage analytics.

• Connector token types are now differentiated per MCP type with JWT claims containing settings information.

Fixed

• Workspace imports now use UUID-only matching to prevent import conflicts and improve reliability.

  Note: This change may affect workspaces where elements have different UUIDs across environments. Before pushing, pull from the target workspace first so you can revert if elements don't match as expected.

• Archive file paths now use connector UUIDs instead of names to prevent key collisions when multiple connectors have the same name.

Added

• Field usage (number) added to AgentSessionDto to track session usage metrics

• Field archivedAt (string) added to ConnectorDto to indicate when a connector was archived

• Is is not possible to edit isReadOnly field when updating org-workspaces.

Changed

Changed

• Login flow now uses a simplified single-mode authentication architecture for improved reliability - no more --tenant parameter (it's silently ignored).

• Improved membrane status output.

Major Changes

• Custom code execution engine was refactored to V8 isolates. It makes it much faster and less resource-consuming.

  • About 5% of custom code requests use functionality not supported by isolates. They fall back to the previous implementation (sandboxed node.js processes).

  • If you self-hoste, you can disable the new custom code engine by adding CUSTOM_CODE_RUNNER_DISABLE_IVM env variable. This can act as workaround if you hit features not supported by V8 isolate and fallback doesn't work.

Changed

• Changes in connection API:

  • connected field on connections that will replace deprecated disconnected field

  • GET /connections now accepts a connected query parameter for filtering connections by status

  • Connection errors are now more consistent with the rest of elements:

    • requestError contains the latest problem with connectivity that made connection disconnected.

    • errors field has all the errors for connection: requestError and any configuration errors

    • error field still stays but is deprecated.

Fixed

• Fixed crash when using the SDK in browser environments that don't support CommonJS require() in the error handling code path.

Fixed
