separate add-ons, such as Turbo Assembler and Turbo Vision 1.0. Turbo C++ 4.0 was released in November 1993 and notable (among other things) for its robust support of templates. In particular, Borland C++ 4 was instrumental in the development of the Standard Template Library, expression templates, and the first advanced applications of template metaprogramming. With the success of the Pascal-evolved product Borland Delphi, Borland ceased work on their Borland C++ suite and concentrated on C++Builder for Windows. C++Builder shared Delphi's front-end application framework but retained the Borland C++ back-end compiler. Active development on Borland C++/Turbo C++ was suspended until 2006 (see below.) Turbo C++ 4.5 was announced on March 20, 1995. New features include multimedia QuickTour, five new games (Turbo Meteors (an Asteroids-like game), Turbo Blocks, Turbo Cribbage, Turbo 21, Turbo Mah Jongg) with corresponding source codes. It includes the ObjectWindows Library (OWL) 2.5, AppExpert, ClassExpert, Object Components Framework. Borland Japan Turbo C++ Version 4.0J supports DOS for PC-9801 and PC/AT (DOS/V). It includes Turbo Debugger 4.0. The IDE uses XMS memory. The project manager supports linking OBJ/LIB libraries, and integration with Turbo Assembler 4.0J. Version 5.0J was announced on 1996-07-23. Based on Borland C++ 5.0J, this version includes an IDE supporting Windows 95 and NT 3.51, and can compile 16-bit software. It includes ObjectWindows Library 5.0, Borland Database Engine, and Visual Database Tools. Borland Turbo C++ Suite This version includes Borland C++Builder 1.0, Turbo C++ 4.5 for Windows 3.1, Turbo C++ 3.0 for DOS. Later release replaces C++Builder 1.0 with Borland C++BuilderX Personal Edition. Turbo C++ 2006 It is a single language version of Borland Developer Studio 2006 for C++ language, originally announced in 2006-08-06, and was released later on 2006-09-05 the same year with Turbo Explorer and Turbo Professional editions. The Explorer edition was free to download and distribute while the Professional edition was a commercial product. In October 2009 Embarcadero Technologies discontinued support of all Turbo C++ 2006 editions. As such, the Explorer edition is no longer available for download and the Professional edition is no longer available for purchase from Embarcadero Technologies. Turbo C++ 2006 was succeeded by C++Builder 2007 before Embarcadero's acquisition of CodeGear and dropping support, and official Turbo C++ 2006 page has later redirected a visitor to C++ Builder 2010.
