- New Features:

- Monitoring of the available space on the disk that holds the SQLite buffer for readings ingested by Fledge has been added. Entries will be written to the error log to predict the expiration of the disk space and also logs when the spaces left available fall below 10% and 5%.
- Failures to send data north via the north service raise an alert, this is now cleared if the flow of data north later resumes.
- Failures to send data north via the north service raise an alert. This is now cleared if the flow of data north later resumes.
- An issue that could cause high CPU utilisation when a north service was unable to send data to the upstream system has been resolved. The user is also made more aware of failed attempts to send data upstream using the alerting feature. An alert will be created and shown in the GUI status bar.
- It is now possible to create allow and block lists for IP addresses that are allowed access or explicitly denied access to the API port of the instance.
- The configuration items within the configuration category now have the ability to limit the user roles that are allowed to update the configuration item.

- fledge-filter-asset now supports to allow regular expressions to be used in the asset name to match when applying the filter.
- fledge-filter-delta has been enhanced to give greater control over the action when one or more datapoints in an asset reading are detected as changing.
- fledge-notify-operation now supports data substitution as with the other control-related notification delivery plugins.
- fledge-north-OMF *action* code in the HTTP header is normally set to *update* for OMF Data messages. This causes old values to be updated if the timestamps match and new data to be properly compressed by the PI Data Archive.
If the AVEVA PI Buffer Subsystem is configured, however, the *update* action code is converted to an internal PI storage mode that causes new data to bypass compression, which can result in unnecessarily storing too many data values. To workaround this issue, the OMF North plugin now allows you to change the OMF Data action code to *create*. This should only be done when the AVEVA PI Buffer Subsystem is configured.
- fledge-south-s2opcua now supports for the OPC UA Data Change Filter has been added. This filter type is defined in the `OPC UA Specification, Part 4, Section 7.22.2 <https://reference.opcfoundation.org/Core/Part4/v105/docs/7.22.2>`_. The Data Change Filter allows OPC UA clients (such as this plugin) to request that the OPC UA server send data value updates only if the server's data values have changed significantly. With careful tuning, you can reduce the data traffic from OPC UA server to the client without significant loss of fidelity. This plugin has been upgraded to use Systerel's `S2OPC Toolkit Version 1.5.0 <https://gitlab.com/systerel/S2OPC/-/releases/S2OPC_Toolkit_1.5.0>`_.
- fledge-north-OMF plugin's *action* code in the HTTP header is typically set to *update* for OMF Data messages. This setting allows old values to be updated when timestamps match and ensures that new data is compressed correctly by the PI Data Archive. However, if the AVEVA PI Buffer Subsystem is configured, the *update* action code is converted to an internal PI storage mode, which causes new data to bypass compression and may lead to excessive storage of too many data values. To address this issue, the OMF North plugin now allows you to change the OMF Data action code to *create*. This option should only be used when the AVEVA PI Buffer Subsystem is configured.
