Type
Description

New

QuestDB Connector v1.00 QuestDB is a high-performance, open-source time-series database built for storing and querying large volumes of timestamped data - such as IoT telemetry, industrial sensor readings, and operational metrics. The QuestDB Connector enables XMPro App Designer to query data from a QuestDB instance using standard SQL SELECT statements, surfacing results directly in your applications and dashboards.

New

XMPro Entra ID Sync Connector v1.40 XMPro Entra ID Sync Listener v2.00 Perform on-demand or scheduled sync operations on XMPro users, business roles, and product access based on Microsoft Entra ID (formerly Azure Active Directory) group membership.

Enhancement

Join Transformation v4.01 Support cross joins for intentional Cartesian products, enabling a guardrail to enforce at least one join condition on all other join types.

Enhancement

SAP Action Agent v7.00 Support API Key authentication when using App Credentials for OData services that require it.

Changed the Secret ID to encrypted. Fixes for URL field validation and entity dropdown visibility when using connection variables, session clearing, and improved error reporting with HTTP status details and SOAP fault parsing.

Breaking change - reconfigure the Secret ID only if you used the App Credentials authentication.

Fix

Azure SQL Context Provider v6.11 SQL Server Context Provider v6.11 Fix single-line comments (--) in SQL queries being commented out at runtime, due to the agent replacing newlines with spaces.

Fix SQL queries failing when moved between Windows and Linux Stream Hosts, due to inconsistent newline handling across operating systems.

Fix

JSON Serializer Transformation v2.11

Fix Combine output returning one row per input event instead of a single combined row when Add Existing is disabled. Fix Input Columns being incorrectly required when Specify Json Path is enabled, causing a validation error even when a valid JSON path definition was provided. Input Columns is now required only when Specify Json Path is disabled; Payload Definition is required when it is enabled.

Fix

Meta Action Agent v2.01

Fix exported agents failing to start on Stream Host v4.6+ by including the Streaming DLL in the export template. Note: Upgrade from v2.00 to v2.01+ if using the capability to export instances as new Agents.

Fix

OpenAI Assistant v2.00

Fix FileLoadException: Could not load file or assembly 'ManagedCuda.dll' on GPU-less Stream Hosts, by validating for GPU availability using CUDA detection on data stream publish. Fix Stream Host container crash with no error message by validating Python paths on data stream publish.

Fix

OSIsoft PI Listener v5.02 & Context Provider v5.02

Fixed Microsoft.Data.SqlClient is not supported on this platform error when selecting an attribute alias on Linux Stream Hosts.

Fix

Run Recommendation v4.01 Renamed Status output attributes FirstRuleName, FirstRuleTitle, and FirstRuleDescription (previously RecommendationName, RecommendationTitle, and RecommendationDescription) to accurately reflect that they return data from the first evaluated rule, not from the Recommendation. Breaking Change: Update input payloads of downstream Agents using the Status output added in v4.00.

Fix

Snowflake Context Provider v2.03 Fix silent data fetch errors in the async poll (ELS) by surfacing them in the Stream Host logs.

Fix data sometimes not appearing in Live View, caused by polls sharing a single database connection that could be stale or closed mid-read by a concurrent poll, by scoping a fresh connection to each poll.

Fix
