publishes now time out and surface errors correctly.** Integration › Edge Gateway ## Integration and Connectors ### Improved - **AWS Firehose connector: New connector with PutRecord and PutRecordBatch nodes, enabling near-real-time streaming of Fuuz data into S3, Redshift, and other Firehose targets.** Integration › Integration Platform - **Integration Connector documentation + schema viewer: A new Connectors tab in the API Documentation shows each connector's input/output schemas in an interactive tree/table view, with a "Copy to Integrate Node" button that generates a ready-to-use flow node.** Integration › Integration Platform ### Fixed - **Fixed Fuuz connector socket timeouts: Applied proper keepalive/timeout settings to the Fuuz connector and enterprise sync to address intermittent socket-timeout errors.** Integration › Integration Platform - **Fixed connection validation on update: Updating a connection no longer fails validation because of encrypted credentials being re-merged into the request.** Integration › Integration Platform ## Orchestration and Data Flows ### Improved - **Script binding docs in the Script Editor: A new collapsible documentation panel (Alt+5) surfaces available bindings directly in the Script Editor, filtered to the bindings usable in your current context.** Orchestration › Scripts - **Bindings added to the API Documentation: The API Docs now include a searchable, filterable reference for all binding-map functions and web-app snippets, with copy-to-clipboard examples and an option to open any example straight into the Script Editor.** Orchestration › Scripts - **Input Payload & Context autocomplete in script editors: The Transformation Explorer and script editors now provide type hints and autocomplete for your Input Payload and Input Context values.** Orchestration › Scripts - **Improved JSONata IntelliSense: Hovering a built-in JSONata function shows its signature, and autocomplete for variables, lambdas, and functions is more accurate.** Orchestration › Scripts ### Fixed - **Fixed "open in Transformation Explorer" links: Links from the dev console now correctly carry event data into the Transformation Explorer again.** Orchestration › Scripts ## Security and Administration ### New - **New account security - permanent lockouts: Administrators can now permanently lock a user out (supporting CFR Part 11 requirements) and choose to lock out users permanently after repeated failed authentication; lockouts clear when the password is changed by the user or an admin.** Data › Security & Administration ### Improved - **GraphQL batching-attack protection: Hardened the authentication service against attempts to bypass rate limiting by batching operations in a single request.** Data › Security & Administration - **Tenant & Role switching in the navigation drawer: Added Tenant Switcher, Role Switcher, and Environment switching to the drawer menu, along with organization information.** (Note: organization grouping may take up to 24 hours to reflect changes until the cache refreshes.)Data › Security & Administration - **Authentication metrics: The nightly metrics sync now captures successful authentication events (last 7 days), visible on the Enterprise Users screen.** Data › Security & Administration - **Persistent submenu icons: Navigation drawer menu groups now show a persistent chevron indicator instead of only on hover.** Data › Security & Administration ### Fixed - **Fixed sign-out error: Signing out from the avatar menu no longer produces an "Authorization Header Not Provided" error and correctly logs the event.** Data › Security & Administration ## Data Models and API ### Improved - **Email address validation: Email fields across the platform are now validated in the GraphQL API, and a new Email Input screen element provides built-in email validation on forms.** Data › GraphQL API - **Create data models from JSON: The Schema Designer can now create a data model with fields populated from pasted JSON data or a JSON schema, in addition to file import.** Data › Schema Designer - **Streamlined model creation: Removed the extra save dialog that appeared when first creating a data model; you can now edit and save freely before deployment.** Data › Schema Designer - **Data export queueing: Exports now queue and run with a bounded concurrency limit, so large numbers of simultaneous exports no longer overload the service and fail.** Data › Data Management ### Fixed - **Fixed deleting heavily-referenced records: Records such as Data Flows with very large reference/log counts can now be deleted without timing out.** Data › GraphQL API ## App Building and Packages ### Fixed - **Fixed application component references: The Application Component References page no longer errors when a referenced Data Flow, Data Model, or Screen no longer exists.** User Interface › Application Designer ## Screens and User Experience ### Improved - **Tenant switch state reset: Switching tenants now properly resets UI state (no more stale components from the previous tenant), and the App Designer preserves your open tabs across page refreshes.** User Interface › Framework - **JSON Schema Predicate Builder: A new schema-driven predicate builder with clearer feedback for invalid predicates, now used by the Data Mapping Filter node.** User Interface › Components - **Screen Designer Structure tab drag-and-drop: You can now drag and drop screen elements in the Structure tab, with tooltips flagging invalid placements.** (The separate Layers and Scripts tabs have been consolidated.)User Interface › Screen Designer - **Screen import/export metadata: Exported screens now embed the screen name, version, and module in their JSON for more reliable re-import.** User Interface › Screen Designer - **Custom export file names for tables: Tables now have an "Export Name" property to control the exported file name (defaults to the screen title).** User Interface › Screen Designer - **"Usable as Widget" default: The Screen Designer save dialog now defaults this checkbox to off instead of requiring a manual choice.** User Interface › Screen Designer ### Fixed - **Fixed select input advanced search: A Select input's additional filter is now correctly applied to the options shown in the Advanced Search popover table.** User Interface › Components - **Fixed table column color toggle: Turning off a column's background color no longer causes that column's text and data to disappear.** User Interface › Screen Designer ## Platform and Infrastructure ### Improved - **Increased MongoDB oplog size: Enlarged the MongoDB oplog across environments to provide a more generous recovery window for replica set members, reducing the risk of full node resync after extended downtime.** DevOps - **Security dependency updates: Bumped @aws-sdk packages to resolve a fast-xml-parser vulnerability (CVE-2026-25896).** DevOps - **System email theme: All system emails (welcome, password reset, MFA code, account locked/reactivated, export complete, and notifications) now use a consistent, Fuuz-styled template.** The System Email flow node can send styled or unstyled emails via a "Wrap in system layout" toggle.Integration › Notifications & Emails ### Fixed - **Fixed adding notification channel recipients: Adding a recipient to a notification channel no longer crashes the page.** Integration › Notifications & Emails
