- Renamed TRSXXXChart.UpdateAxisInfo method override to
TRSCustomChart.DoUpdateAxisInfo method
- Added TPathOption and TPathOptions type
- Added DefaultPathOptions constant
- Added ctPathChart to TRSChartType
Known Bugs:
- TRSDBPathChart is untested

Note: This release dramatically changed support classes in order to
better support XE4 Mobile compiler features: Automatic Reference Counting,
TList deprecation, and suggested deprecation of Pointer type. It makes
heavy use of generics instead of older TList-type and TGHashTable classes
which used pointers. A lot of effort has gone into making the new classes
support the same methods and properties of the old classes. However,
there may be changes needed to be made to your code. Of special note:
- InterfaceCollections unit has been replaced with RSInterfaceCollections unit
- Contnrs.pas, GLists.pas, and GHashTable.pas have been replaced with
System.Generics.Collections.pas or RSGenerics.Collections.pas
The old units are still available but are not used.
-------------------------------------------------------------------

- Dropped RAD Studio 2009 Support
- Refactored classes to use generics versions of lists and hash tables instead
of classes from Contnrs.pas, GLists.pas, InterfaceCollections.pas,
Structures.pas, and GHashTable.pas
- Refactored Packages (dpk) to use $IFDEFs with $LIBVERSION
to create multiple compiled versions for each version of Delphi
from the same package file
- Renamed RSCharts.dpk to RSCharting.dpk
- Added [Weak] Attribute to owner objects references for
Automatic Reference Counting (ARC) compiler
- Replaced Free calls with DisposeOf for NEXTGEN compiler
- Removed Free calls for NEXTGEN compiler
- Renamed TRSLegendListBox.DoApplyStyleLookup to DoApplyItemStyleLookup

compiler
