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

Connections now have key and can be identified in code-friendly way.
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

External apps are now sorted by popularity in the interface
Connections now start in a disconnected state until successfully authenticated. This only affects behavior of the new connected field and doesn't affect the old/deprecated disconnected field.
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

OAuth loopback redirect URIs now support any port number per RFC 8252 standards
Connection refresh button in the console now triggers a backend refresh of the connection
Auth Proxies admin link now appears correctly on self-hosted installations
Unsupported event types now show proper error messages instead of crashing
Flow run errors from individual nodes now properly propagate to the overall flow run
OAuth consent page now properly displays tenant dropdown options
Workspace logo and app icon components now include fallback image handling
Connection refresh attempts no longer cause authentication errors when retrying disconnected connections
Schedule triggers no longer fire multiple times due to duplicate node schedules
Organization invitation acceptance is now idempotent instead of failing silently
Expert tasks route now displays properly under the activity section
External app are now marked as connected immediately after connection creation.
Connection building agent sessions now receive complete context information
Archived connectors are now properly excluded from workspace exports
Rate-limited event pulls are now handled proactively with proper backoff strategies
Queued runs are now properly stopped for misconfigured and disconnected connections

CLI 1.16.2

Thu, 16 Apr 2026 00:00:00 GMT

Fixed

Fixed a crash caused by missing exports in the CLI package.
Fixed login flow to use the correct API URI when authenticating.
Fixed internal dependency version pinning to ensure stable package installations.

CLI 1.16.0

Mon, 13 Apr 2026 00:00:00 GMT

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.

API Contract 1.11

Mon, 13 Apr 2026 00:00:00 GMT

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.

Improved membrane status output.

Platform 2026-04-03

Fri, 03 Apr 2026 00:00:00 GMT

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.
Agentic Connection UI is now used by default instead of "static" connection UI.

Changed

Connection state tracking simplified with clearer connected and error status fields.
Non-agentic connection screens now redirect to the improved agentic flow
Flow descriptions automatically sync between universal and integration-specific versions.

Fixed

Connect buttons now work properly for connectors without named authentication options
OAuth consent page shows helpful messages when revisited after approval
Connection configuration errors clear automatically after successful recovery
Action tabs between universal and integration versions navigate correctly
Console navigation works properly when flow re-runs fail
Actions and elements can no longer be created without required key fields

API Contract 1.10

Fri, 03 Apr 2026 00:00:00 GMT

Added

New endpoint: PATCH /org-workspaces/{id}/user-settings for updating user workspace settings

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.
