Note: some of new Delphi features are already implemented in FPC trunk.
New since Delphi 2007
Advanced Records
http://docwiki.embarcadero.com/RADStudio/en/Structured_Types#Records_.28advanced.29
Advanced records are implemented in FPC 2.6.X without record constructors. Record constructors are implemented in FPC 2.7.1 (trunk).
New since Delphi 2009
Generics Syntax
A good delphi reference is here: http://docwiki.embarcadero.com/RADStudio/en/Generics_Index
Partially implemented in 2.5.1/2.6.x, further improved in 2.7.1 by Sven
Support for ansistrings with a definable codepage
Initial implementation available in trunk (2.7.1). Useful for small time testing, but the whole of the codebase hasn't adapted (2011-10-18)
Anonymous Methods
New since Delphi 2010
Custom Attributes
Enhanced RTTI

AS and IS extended for interfaces

Misc
- (Library) packages
- "automated" keyword, which is like "public", but generates COM specific RTTI. Afaik this kind of COM usage is deprecated though.
