<ts:value>1</ts:value>
</ts:setting>
</ts:section>

Fixed
VIS-3288 Improvement

VISU : Trend : Option to free trend handles after leaving the trend view

Fixed [[GENERAL]]
The issue as originally described could no longer be reproduced.
Nevertheless the trend element in the visualization does keep file handles open by default to deliver the best possible performance when switching to according visualizations.
For PLCs that have problems with this behaviour due to a limited number of files that can be open in parallel,
the behaviour can be changed by adding to the device description
In:
<ExtendedSettings>
<ts:TargetSettings>
<ts:section name="trendrecording">

This new setting:
<ts:setting name="remove_notvisible_handle" type="integer" access="visible">
<ts:value>1</ts:value>
</ts:setting>

Using this targetsetting, the trend element in the visualization will close their file handles when the visualization containing the trend element is left. This modified behaviour allows to use more trend elements on such restricted devices than before. The file handles required for recording the trend data will be kept open independently of this targetsetting value.
VIS-3285 Bug

Table use a struct with ENUM with option template has compile error

Fixed
VIS-3284 Improvement

WebVisu: Browser does not display max nbr of vis clients with active user management

Fixed [[GENERAL]]
After a successful login using the login page, there is a check if the maximum number of clients has been reached.
In this case a according message is shown.
VIS-3201 Bug

Visu Editor, Snap lines, move element out of group, element jumps by one pixel

Fixed [[KNOWN_LIMITATIONS]]

Fixed
VIS-2963 Improvement

Alarm Manager: Do not delete text in text list for existing IDs if message text is empty

Won't Fix [[GENERAL]]
As this suggested improvement does not solve the original customer problem, the issue will not be be fixed. Another improvement will resolve the situation in a more user-friendly way: VIS-3421
VIS-2961 Improvement

Add new target setting for maximum_number_of_visualization_clients

Fixed [[GENERAL]]
There is a new targetsetting to limit the number of maximum visualization clients. Any value lower than the client limit will be accepted. There will be a compile error if a bigger one is configured.
Setting: visualization\\targetsupport\\maximum_number_of_visualization_clients_limit
VIS-2919 Improvement

Visu: The elementname should be available in the iec application

Fixed [[GENERAL]]
The name of the element can be set in the property 'Element name' and must not begin with 'GenElemInst_'.
The 'GetElementName' method for obtaining the element name is in the 'VisuElems.IElementNameProvider' interface, which is derived from the 'VisuElems.IVisualElement' interface.
The interface 'VisuElems.IVisualElement' is e.g. passed into the variable 'IVE' during an 'Input' activity on the element or by instantiating an FB that implements the 'VisuElems.IValueChangedListener' interface.

[[COMPATIBILITY_INFORMATION]]
If non default element names are used in existing visualizations, the amount of required memory of the visualization might increase a bit as each non default element name has to be downloaded and stored by the according visualization in order to provide it at need.
Of course this applies only if Web-, Target- or Remote Targetvisu are used.
VIS-2852 Bug
