Compatibility issues

TCustomRichView.DeleteLines is renamed to DeleteItems.

If you assign non-default values to extra item properties, saved RVF files will not be opened with applications that use older version of RichView.

OnDrawPageBreak event has additional parameter. If you already use this event, you must change declaration of event handler manually.

All references to TImageList were replaced with TCustomImageList. Especially important: parameter of OnRVFImageListNeeded was changed; if you already use this event, you must change declaration of event handler manually;

FirstIndent is not applied to line starts inside paragraphs ( Shift + Enter ).

DeleteUnusedStyles has a new parameter (deleting list styles).
