  • Added support for managing secrets and passwords external to the project.
  • Added success and failure paths to Pipeline Write stages.
  • Added a new Connection for Google BigQuery.
  • Added new Buffered Ingest support to AWS IoT SiteWise Outputs.
  • Added functions to project import and export.
  • REST Client Connector Inputs and Outputs now support GET, POST, PUT, PATCH, DELETE methods.
  • Added an application setting to easily enable advanced debug logging.
  • Enhanced the Pipeline Read Stage to allow for inline read results in the event payload.
  • Added a new Point Browse Input type to the PI Connector to query the PI Archive for points and metadata.
  • Enhanced the metadata returned for PI Point reads of Current Value with Include Metadata enabled.
  • Enhanced SQL Browse to be able to see and browse across table schemas.
  • Added passive mode support to the File Connector in FTP mode.
  • Added a server type option to the File Connector to select Unix (Default) or Windows types in FTP mode.
  • Added a configurable connection timeout to the PI System Connector.
  • Increased the default size of VARCHAR/String columns created for SQL tables from 256 to 2048.
  • Added new setting to CSV Inputs to set the quote and escape characters.
  • Enhanced the UNS Client to automatically select the first MQTT or Sparkplug connection in the list and to remember the previously selected connection.
  • Enhanced the Pipeline UI to provide more space when configuring and troubleshooting Pipelines.
  • Enhanced the S3 Output to allow setting the Content-Type.
  • Changed the unlicensed version to run fully functional for two hours at a time.

Breaking Changes:
  • Changed the behavior of the system level “Allow Environment References” Setting to only import environment variables that start with “PUBLIC_”. Prior to this change, all environment variables were available. This could possibly leak secrets and other information. This change requires customers to change any environment variables they are using to start with “PUBLIC_”.
  • SQL outputs using Update/Upsert with a WHERE that is just the column name must update the WHERE clause to be an expression (ex. mycolumn = ‘’).
Fixes:
  • Fixed an issue where an OPC UA Connection could consume too many threads in certain error conditions.
  • Fixed issues where invalid Sparkplug metrics could cause read failures for the entire Input.
  • Fixed an issue where Webhook Inputs were incorrectly parsing XML arrays into strings.
  • Fixed an issue with the UNS Client where subscribing to an invalid topic caused rapid re-connection attempts.
  • Fixed an issue where browsing an empty OPC UA branch navigated the user to an empty screen with no tags to select. The user now stays on the same page with a message saying no tags were found.
  • Fixed an issue where the Flow Trigger Delay was not shown for Flows that were in Polled mode.
  • Fixed an issue where enabling the “Ignore Self Signed Certificates” for MQTT and Sparkplug Connections disabled the ability to use Client Certificate/Key authentication.
  • Fixed an issue where refreshing the Connection Statistics page caused outputs to be de-selected in the UI.
  • Removed a warning produced for SQL Output updates in cases where no rows were found to update.
  • Fixed an issue where switching from a PI System Input Point Current Value to a Raw Values read could cause read errors.
  • Fixed a UI issue where additional read sources could be added to a Read Stage when a Pipeline was in replay mode.
  • Fixed an alignment issue in the OPC UA Input Methods UI.
  • Fixed a bug where incorrect text was shown over the Tag selector when hovering.
  • Fixed an issue where a plus icon was shown in the SQL table browser.
  • Fixed an issue where Project page step numbers had incorrect formatting.
  • Fixed an issue where console.log messages logged in Pipeline Transform stages were not shown in the UI for troubleshooting.
  • Fixed an issue with the Docker image where the Store and Forward directory did not default to the appData directory, resulting in Store & Forward data being lost on container reboots.
  • When “Include Metadata” is enabled, REST Client reads that return non-200 level responses now return the error code and message in the same format as 200 responses.
  • Fixed an issue where the UNS Client could not connect to secure MQTT connections.
  • Fixed an issue where SQL Inputs that did not run SELECT queries returned bad status.​​
 
Security Patch Updates:
  • Amazon Kinesis Data Firehose
    • CVE-2024-21634: DOS when deserializing data from untrusted source. It is not possible to execute this code in the HighByte Intelligence Hub implementation.
​
Patch (3.4.4 2024.6.12.2):
  • Added support for Sparkplug Inputs to receive data from edge nodes that do not publish birth certificates. This does not work if metrics use aliases in the publish.
  • Added Binary and ASCII modes to the File FTP Connection to support reading/writing binary files without modifying them. 
  • Changed the UI to hide password fields when they are being entered in connections settings.​
  • Improved Snowflake Streaming output performance by avoiding metadata queries that caused warehouse compute costs. 
  • Fixed a bug where the product name was changed from “HighByte” to “Highbyte”. This could result in existing OPC UA Connections failing with a Bad_CertificateUriInvalid error, because the name in the certificate did not match the name used in the connection.
  • Fixed a bug with SQL Outputs where column names were being matched to the output data as case sensitive, resulting in failed writes or missing data.
  • Fixed issues with OPC UA reading empty primitive arrays and null objects in Structured Data types.
  • Fixed an exception thrown and displayed in the logs when writing to an invalid IP or hostname from a Write New stage.
  • Fixed an issue where remote hubs with older versions could connect to a central hub on version 3.4 but configuration requests would timeout.
  • Fixed an issue where SQL Inputs with multiple lines returned the first line and not the first result. For example, if a statement had an insert followed by a select, it would return “good no data”. Now it returns the select result.
  • Fixed an issue where templated Inputs or Instances that had a dynamic reference that required more than one read could cause a deadlock. An example would be a Condition that parses SQL data into template parameters. The deadlock could occur on startup or anytime the runtime is restarted (e.g., settings change, redundancy change over).
  • Fixed an issue where SQL connections would not recover from a disconnect in some cases.
  • Fixed OPC UA Connection threading issue that could result in reads and writes no longer working on the connection. This could occur in some cases where the connection is dropped because of request timeouts or other network issues. 
 
Patch (3.4.5 2024.7.18.2):
  • Fixed a bug with Sparkplug CMD inputs where multiple commands sent in a single message could cause event based Flows to not execute. 
  • Fixed an issue with Microsoft SQL Server, PostgreSQL, Google Big Query inputs where reads would check the SQLite cache for the latest index value when indexing was disabled. 
  • Fixed an issue with Active Directory (AD) authentication where a blank password could grant product access if the ‘LDAP unauthenticated authentication’ isn’t explicitly disabled in AD. Logins are now rejected if the username or password fields are empty.

 

Patch (3.4.6 2024.11.4.2) 
  • Fixed an issue with getting and setting Pipeline state that could cause native system memory leaks.
  • Enhanced the OPC UA Events input to support custom event attributes that exist outside the default namespace using a N:attributeName syntax, where N in the namespace number.
  • Fixed an issue where the REST Client connection could not connect to an endpoint that only supported TLSv1.3.
  • Fixed an issue reading PI Event Frames that had null attribute values.
  • Fixed an issue in the InfluxDB Connection with escaping spaces in measurement names and tags. 

 

HighByte Intelligence Hub Version 3.3

New Features: 
  • Added a new Snowflake Streaming Connector that uses the Snowpipe Streaming API to create and write to tables in Snowflake.
  • Added a new Snowflake SQL Connector that supports reading data from Snowflake using the JDBC Driver.
  • Improved the speed and memory usage when working with large data sets.
  • Added support for limiting REST Data Server read and write access using user roles and claims.
  • Enhanced the Pipeline user interface (UI) to include additional stage and pipeline status.
  • Enhanced the Pipeline UI to include a new event replay feature to easily troubleshoot workflows.
  • Added support to the Pipeline “On Change” stage for compressing arrays.
  • Added an Array Builder in the UI to aid in building arrays of objects for Instance Attributes.
  • Added the ability to get the name, model, and path in Instance Expressions.
  • Added a new “Create & Update” option for SQL Outputs to support automatically adding new columns to a table when new attributes are written.
  • Added a new “Table Cache Interval” setting to SQL Outputs to detect changes in the table schema on a given interval. This allows the Output to write to new columns that are added to the table manually.
  • Added support for Modbus Outputs.
  • Added Browse support to the AWS IoT SiteWise Connector.
  • Enhanced Flow Templates to expand Targets.
  • Added metrics to Connections for pending Connection writes and dropped rights.
  • Added the ability to clear the Store and Forward cache for Connections via the UI.
  • Improved Connection write queuing when Store and Forward is disabled to reduce the occurrence of dropped write errors and retry writes in FIFO order.
  • Improved rendering performance of the UNS Client.
  • Added the ability to clear retained messages by publishing an empty payload in the UNS Client.
  • Added a warning event log message if the runtime is unable to write to the appData directory.
  • Test Reads now show a warning in the UI to let the user know that the result is truncated.
  • Updated the product favicon.

Breaking Changes:
  • When a parent Instance includes a child Instance, the Model Attribute “Array” switch no longer performs Array Expansion on the child Instance. To perform this expansion, enable the “Expand Arrays” feature on the child Instance directly. The Model Attribute “Array” switch now serves to expose the new Expression Builder to help build out arrays of objects and will transform single values and scalars in the expression result to array types. 
  • The AWS IoT SiteWise Output was changed to cache Assets by unique path versus by unique name. If an Asset exists at the root of the IoT SiteWise hierarchy but an Output has the “Parent Asset” field set, the Asset will be re-created under the Parent Asset. To migrate this, either clear the “Parent Asset” setting for the Output or manually move the Asset in IoT SiteWise to be placed under the Parent.
Fixes:
  • Fixed an issue where an Apache Parquet file could be created with a zero-minute duration.
  • Fixed a bug where MQTT Inputs could produce duplicate events for a single message.
  • Fixed an issue where all PI System writes failed if a single write had an invalid reference.
  • Fixed an issue where the PI System Connector was not retrying write failures when failing to connect to the PI Agent.
  • Fixed a bug with the PI System Connector where Standard Deviation and other Input types would return Average results.
  • Fixed an issue where renaming a Network Group could cause a loss of Network Hubs assigned to the group.
  • Fixed an issue where Int64 and UInt64 values did not always work when used in Flow triggers.
  • Fixed an issue where files were not created as UTF-8 encoded in some JVM versions.
  • Fixed issues where Pipeline Status was not updated correctly or was delayed.
  • Fixed an issue where Dynamic reference errors on Outputs would not produce useful error messages for troubleshooting.
  • Fixed an issue where no error was reported if a user could not be found in Active Directory.
  • Fixed an issue where items in a list page (e.g., List of Instances) would not immediately be removed from the list page after deletion.
  • Fixed an issue where it was possible to open multiple expression editors in full screen mode.
  • Fixed an issue where Sparkplug would output “Unknown” data types, causing issues with Ignition and other Sparkplug clients.
  • Fixed an issue with Sparkplug Output command (CMD) messages throwing an exception.
  • Fixed a bug where the MQTT Broker would disconnect a client leading “/” character or empty path segment “//”.
  • Fixed an issue where the SQLite event log could grow beyond the size limit.
  • Fixed an issue where a Model allowed two attributes with the same name.
  • Fixed an issue there the System statistics object for Flows was not available when the Flow was disabled.
  • Fixed an issue where project import failed when a Connection had an invalid Uniform Resource Identifier (URI).
  • Fixed an issue where an OPC UA Connection reported good status with a subscription with no valid tags.

​Patch (3.3.1 2024.5.15.1220):
  • Fixed an issue where templated Inputs or Instances that had a dynamic reference that required more than one read could cause a deadlock. An example would be a Condition that parses SQL data into template parameters. The deadlock could occur on startup or anytime the runtime is restarted (e.g., settings change, redundancy change over).

  • Reduced error messages logged by Flows and Instances when there are reference errors.
  • Fixed an issue on OPC UA connectivity loss where UA subscriptions were not re-created properly, resulting in read errors.
  • Improved performance of Store and Forward for all Connections.
  • Added the Browse Variable Nodes option to OPC UA outputs. This was added for OPC UA Inputs and may also be needed in some cases for Outputs when writing complex data.
  • Fixed a Sparkplug Output issue where bad quality data was published as an Unknown data type, causing Ignition to fail to parse the metric and show the tag as bad quality.
  • Changed the Sparkplug Output to not publish the default “HighByte IntelligenceHub” group if it’s not being used.
  • Fixed a bug in the SiteWise Output where, on certain Linux operating systems, the Output would leak threads and result in an out of memory error.

  • Enhanced the tagging view to allow users to more easily see what is tagged.
  • Enhanced the UI for the REST Client headers to enter each header in a table format.
  • Renamed the license file from intelligencehub-license.json to intelligencehub.license.
  • Added an error log message to Connection Outputs if a write is dropped, because a previous write is in progress and store and forward is disabled.
  • Updated Custom Conditions to not cache the lastValue if lastValue is not used in the expression.
  • Improved the 404 error page shown in the UI to include information on the object that cannot be found.

  • Added the ability for payload attributes to retain their original data types when passed through a JavaScript expression.
  • Added the ability to auto-generate an admin password on initial startup when using the HIGHBYTE_AUTOGENERATE_ADMIN_PASSWORD environment variable.
Fixes:
  • Fixed an issue where indexing was not working for PI Connection Raw Point read types.
  • Fixed a bug where Webhook Connections created in version 2.5 would not work in 3.0 or 3.1 unless they were re-saved in the UI.
  • Fixed a bug in Data Pipelines where a Write New Target stage would fail to write if the connection had store and forward enabled.
  • Fixed a bug in PI System Outputs where including a _name attribute in the payload caused points to be prefixed with the _name value.
  • Fixed a bug in Remote Hub connections where the connection failed if the remote hub hostname did not meet the internal naming conventions (e.g., only numbers).
  • Fixed issues when trying to start an Event based flow with a non-event based source did not result in a Flow status error.
  • Fixed a bug in the File Connector where writing to an invalid directory did not cause the Flow to go into error.
  • Fixed a bug in PI Outputs where milliseconds were removed from ISO-8601 timestamps.
  • Fixed a bug in PI Inputs where Indexing would fail to increment for large queries.
  • Fixed a bug where Parquet File test reads with Indexing enabled would always read from the start of the file and not from the current index location.

  • Fixed a bug where indexing PI Point reads could return duplicate payloads.
 
Breaking Changes:
  • Changed the AWS IoT SiteWise Output to no longer build out Asset names using “parent.child” hierarchy. IoT SiteWise no longer requires asset names to be globally unique. This change requires users to re-create Assets or use a Pipeline to re-create the previous naming hierarchy.
  • Changed Sparkplug Inputs to not include the Device name in the payload if the Device name is explicitly set in the Input. The “Include Metadata” option can be used to access the Device name.

Patch (3.1.1 2023.6.1.735):
  • Reverted change that improved efficiency of Instance array expansion. This change broke Instance expressions that used let or const to define JavaScript variables. This build allows let and const to be used as they were in prior versions. The efficiency improvement will be revisited in a future release.
  • Fixed a bug where flows were not restarted automatically when some flow dependencies of the flow were updated.​

Patch (3.1.2 2023.6.22.786):
  • Changed the Element Graph Import to not link child Instances that are referenced in dataProperties. This removes duplicate child Instance references in some cases.
