Pm8.03.15: In the history viewer the placement of time navigation buttons has been optimized.
- Bugfix of opening alarm/event viewer on the Web. If $vb was used then in the alarm group identifier the expression was evaluated as empty.
- Bugfix of memory data overwrite while writing into DBF (DBF alarms) if the written value size exceded the column size in DBF.
- The history data can now be saved also in MySQL database and FireBird database (see the "Storage type" configurator).
- In the Acknowledge method, now it is possible to enter the national language of acknowledging user.
- The localisation of national languages has been improved in Web client.

Pm8.02.14: Fixed bug: (alarm history viewer):
- Fixed bug: while the filter was on and with remote alarms (if Storage type = Remote connection via the Web) the scrollbar did not work correctly.
- Optimalization of search and reading of data from history files.
Pm8.02.13: Fixed bug: If the "Delete inactive acknowledged (green) (valid only for dynamically created items)" configurator was set in the alarm state viewer, then the alarms were not displayed in the alarm history viewer.
Pm8.02.12: Fixed bug: The filtration text is now also transferred when switching between history viewer and status viewer.
Pm8.02.07: Fixed bug: The GetStateData method did not return data if the type was set to "Remote connection via the Web".
Pm8.01.10: If set for the Remote connection via the Web type, then the filtering text did not work if diacritics (i.e. national dependent characters) was used.
- The AckerId property was returning incorrect value.
- If the XML configuration file contained an error, then the alarm viewer was unable to open.
- new configurators: Change inactive acknowledged (green) CEASED to NEW non-initialized alarms in [s] (-1=never) and 2 = Hide only new non-initialized allow to configure the alarm viewers so the alarms in the state inactive acknowledged (green) will be displayed in the alarm state viewer only for a defined period of time - for example for 10 hours, so the following shift operators see what was going on previously.
- events onStateChange and onUserItemAction now contain a new pEvent.Context parameter that allows to identify for example the network user that confirmed some alarm.
Pm8.00.06: Generalization: The "Delete inactive acknowledged (green) (valid only for dynamically created items)" configurator has new option "2 = Hide only new non-initialized".
