Fixes:

• Fixed an issue where SQL Connector writes could fail or insert data in incorrect columns when inserting arrays of data with different data shapes.
• Fixed test Input and Instance reads to not update Connections cached state.
• Fixed an issue where reading OPC UA nodes with opaque node IDs could cause a memory leak.
• Fixed an issue where OPC UA Strings with multi-byte UTF-8 characters were not encoded properly.
• Fixed an issue where OPC UA Numeric Node IDs with IDs larger than max Int32 caused read errors.
• Fixed an issue with OPC UA GUID and Opaque Node IDs not appearing correctly in the UI.
• Fixed an issue where the OPC UA Namespace Index could not be parameterized.
• Fixed an issue with incorrect or missing error messages when using invalid template parameter ranges.
• Fixed an issue with templated inputs failing when template names contain invalid characters.
• Fixed an issue where Instances would fail to convert values of type File to type String.
• Fixed an issue with the reference panel when expanding disabled Aggregate Conditions.
• Fixed an issue where Conditions failed to synchronize between hubs.
• Fixed an issue where project synchronization between hubs did not include Connection passwords.
• Fixed an issue where Azure IoT Hub, Event Hubs, and Blob Storage connection strings were not encrypted.
• Improved the execution speed of Custom Conditions.
• Changed the Aggregate Condition results to return the latest value for non-numeric fields.
• Fixed a bug in the initial release of version 2.5 that caused 501 errors (not implemented) in the browser when remotely configuring a hub in Central Configuration mode and clicking the Network tab.

 
Breaking Changes:

• Custom Condition expressions now require all root JavaScript variables to be declared with var and not let or const. Variables defined with let or const will produce “already defined” errors when reading the condition. Custom Condition expressions are now built once and executed on each read, providing a significant performance increase. Variables declared with let or const at global scope can only be assigned once.

Patches (Build 2022.10.17.311):

• Fixed an issue where the Azure IoT Edge Connector would disconnect and not reconnect unless the connection was saved again.
• Fixed an issue where the Azure IoT Edge Connector would not work when the host machine running Azure IoT Edge was Linux/Unix.
• Fixed an issue where Sparkplug Connector did not output bad quality data when the source quality went bad.
• Fixed an issue where outputting String Arrays with the Sparkplug Connector resulted in repeated re-births.
• Fixed various issues when reading from a SQL table and sending to Parquet output where data types could be lost if the SQL table contained NULL values.
• Added File data type support to Store and Forward.
• Enhanced the REST Client Connector to output the response body to the log on errors to make troubleshooting easier.
• Enhanced the REST Client Connector to better find and extract file payloads when the input is in Binary mode.
• Fixed an issue where attributes starting with an underscore failed to write to PI points.
