Overview

Watch this video to see a summary of what’s new in this release:

Key Features

Added

• Added OAuth 2.0 (Client Credentials flow) as an option for authenticating to Arc’s public API endpoints (Admin API, Flow API, Webhook, and so on).
• Added the ability to control HTTP status codes and response headers in the Flow API via the API-Response-StatusCode and API-Response-Header-{HeaderName} message headers.
• Added support for triggering a receive as the first step in a Flow API flow.
• Added the ability to promote incoming HTTP header values as metadata on messages in the Flow API.
• Added a Flow API resource to the Admin API.
• Added the ability to establish Version Control connections via OAuth and SSH directly in the UI.
• Added the ability to restore files from a commit in the version control UI.
• Added the ability to delete local branches in the version control UI.
• Added audit log entries for version control operations.
• Added the ability to control the Max Files Per Hour that flow through the Schedule connector.
• Added a Discard connector to provide a clean terminal point for flows that produce unwanted messages.
• Added the ability to filter by tracked headers in the Transactions tab of each connector.
• The md5hash, sha1hash, and sha2hash formatters now support binary content by accepting a new encoding parameter (utf-8, hex, or base64) for the input data, enabling use cases like hashing image files.
• Added the ability to migrate CData connector instances to their new dedicated connector types. The CData connector is now deprecated.
• New installations of the Arc Cross-Platform Edition now use H2 as the default database.
• Added an archive folder within the Application Directory as the default archive location for new installations. Existing configurations without Archive Location set will continue using each connector’s local “Archive” folder, but this behavior is now deprecated; Archive Location is required going forward and connector-specific archive folders will be removed in a future release.

Changed

• Improved application database performance through partitioning when PostgreSQL is configured as the backend database.
• Improved the performance of the application database by automatically determining the partition interval when SQL Server or PostgreSQL is used.
• Changed the default value for Log Messages to be False in connectors where messages simply pass through (Branch, Copy, Notify, and so on).
• Changed the default value for Log Level to be Error in connectors that simply route messages in the flow (Copy, Validate, Workspace Send, and so on).

Fixed

• Corrected the response code returned by the server when attempting to access a public URL endpoint associated with a connector that does not exist.
• Fixed an issue that occurred in some Script contexts when processing messages with more than 32,768 duplicate header values by gracefully discarding the earliest excess values and logging a warning instead of failing.
• Fixed SSO JIT provisioning so that removing a user from their identity provider group now correctly revokes their application access.

Connectors

Added

• Added new versions of the REST, Email Send, and Email Receive connectors with improved UIs, support for shared connections, and more. Existing connectors of these types can be upgraded automatically by clicking the upgrade button in the connector UI or the connector’s shape in the flow designer.
• Added a configurable Response Event Error Behavior setting to the REST connector that controls how exceptions thrown in the Response event are handled.
• Added Claude and Grok to the list of supported AI providers in the AI connector.
• Added the ability to use SendGrid in the Email Send connector.
• Added a Maximum File Size setting in the FTP and SFTP connectors to avoid downloading files above a size threshold.
• Exposed connection pooling related settings for the SQL Server, PostgreSQL, and MySQL connectors and changed the default behavior to enable connection pooling.
• Added the ability to specify a collection of related XSD files to be used in the XSD connector.
• Updated MFT connectors with caching enabled to automatically prune stale entries from the cache.

Changed

• The AI connector is now generally available and is no longer marked as a beta connector.
• Changed the default behavior of the Email Receive connector to skip processing of messages marked for deletion on the IMAP server.
• Updated the AMQP connector to align with the AMQP protocol specification for content type handling. Users who previously relied on the Binary value type to carry content type on outgoing messages must update their configuration to use the Data value type instead.
• Due to an issue in the underlying SFTP component, users who are upgrading from build 23.1.8542 or earlier that are using the Timestamp Comparison setting to only download new or changed files should enable Use GMT File Time in the Advanced tab of the SFTP connector.

Fixed

• Fixed several issues in the SharePoint connector that prevented subfolders from being automatically created in non-English SharePoint sites.
• Fixed an issue preventing aggregate columns from being properly represented as XML in the lookup action of database connectors.
