Delphi 2010 is a specific version of Delphi.

Delphi 2010 was released in August 2009, and is available as a standalone product or as part of RAD Studio 2010.

Delphi 2010 codename is Weaver.

Some of the major features of the Delphi 2010 release include:

  • The introduction of a new, rich RTTI (reflection) API that far exceeds the level of detail available in previous Delphi editions.
  • Full Windows 7 support at the compiler and standard library level.
  • Built-in VCL-level support for touch, multitouch and gesture input, even on earlier Windows versions without OS-level touch support.

Delphi 2010 was preceded by Delphi 2009 and succeeded by Delphi XE.
