- Added the ability to delete the datastore.
- Added support for the CSV import and export of historical tags under a historical tag group.
- Added support for 64-bit data types, including QWord and LLong.
- Added buttons to browse the directories for the Datastore Location and Import Location.
- Enhanced the multi-tag edit dialog to allow users to only edit a subset of the tag properties. Leaving a field blank will not apply any changes for that field to the selected tags.
- Added the new "Historian Service Status" field to the Status view to help troubleshoot issues when the Historian service is not running. The field shows started, stopped, disabled, or not installed.
- Simplified the tag dialog to allow dynamic or static tag address creation.
- Fixed a defect where tags would not be renamed if the server channel, device, or tag was renamed. This could occur in cases where the name changed in case only.
- Fixed an issue where closing the configuration when the Tag Browser was being used could result in the configuration crashing.
- Tag groups are now given a default name upon creation.
- Fixed an issue where the Value Display view was not updated with new settings until a new value was recorded for the tag. The view is now updated when the setting changes are made.
- Fixed an issue that occurred when adding String or Boolean tags where the deadband option was not shown as disabled. These data types do not support deadband.
- Fixed a missing help file link from the tag dialog page.
