Fixed
COMM-719 Bug

IecSymbolPublishing: There is no typedefinition set for variables

Fixed
COMM-709 Bug

DataSource: The reading of data is not performed using a different mapping.

Fixed [[GENERAL]]
The datasource within the project showing this problem is broken and it's not likely that many projects are suffering from a similar problem.
Therefore, such broken projects will not be fixed automatically. Instead the bugfix prevents that new such projects will be created. For datasources suffering from this problem, the easiest fix is to recreate the datasource.
COMM-707 Bug

New SymbolConfiguration: Exception while accessing a variable of packed structure (with pack_mode:1 attribute)

Fixed
COMM-702 Bug

Comm, UA Server, IEC Symbol Set Editor: Exception when modifying Access Rights of Symbol Types

Fixed [[GENERAL]]
Only the InvalidOperationException has been fixed

[[KNOWN_LIMITATIONS]]
The 2nd problem cannot be fixed.
The editor uses a standard Windows control, whose behaviour considering the right mouse click cannot be changed (The Windows Explorer is also based on this control and has the same effect)
COMM-699 Bug

Symbol Set: Type from library is incorrectly displayed as not available

Fixed
COMM-697 Bug

SymbolConfig: Variables get lost (unselected), after editing data type

Won't Fix [[GENERAL]]
The symbol configuration object will be deprecated and only severe issues will be fixed. For the usage of symbol sets and OPC UA the new editors of the Communication Manager object should be used.
COMM-695 Bug

Datasources: Error on Update Variables with Enums and Arrays

Fixed
COMM-676 Bug

OPC UA Symbols are not available when using boot project

COMM-673 Bug

Fixed
COMM-633 Bug

OPC UA Symbol Set: No uniform change of values for DUT

Fixed
COMM-625 Bug

SymbolConfiguration: Exception while accessing a variable of packed structure (with pack_mode:1 attribute)

Fixed [[GENERAL]]
A new error message is reported if a unaligned value is published in the symbolconfiguration on a device that does not support unaligned access to memory. The message has the pattern "Unaligned member <> of type <> cannot be published".
This error prevents the download of the potentially broken code, that might lead unpredicatable crashes of the controller.
Setting a application define "symbol_config_no_check_alignment" disables this check.
