The dzDebugVisualizer plugin previously only had packages for Delphi 2005, 2006, 2007, 2009, 10.2, 12, and 13. I have now added packages for the 14 missing versions: Delphi 2010, XE, XE2, XE3, XE4, XE5, XE6, XE7, XE8, 10.0 Seattle, 10.1 Berlin, 10.3 Rio, 10.4 Sydney, and 11 Alexandria.
All versions from Delphi 2010 onwards use the official OTAPI debug visualizer interfaces and share the same source code. The differences are only in the package files and project settings.
The full feature set is available on all new versions, including the TColor visualizer, TNullable visualizer, and the Universal visualizer. For the Universal visualizer configuration, Delphi XE and later use the IDE Options page (Tools > Options), while Delphi 2010 uses a standalone configuration dialog accessible via the Tools menu.
The source code is available on SourceForge.
