New in 7.0: Core Language
Built on powerful and elegant principles, the core Mathematica language has emerged over the past 20 years as perhaps the world's richest and deepest programming language. Version 7.0 builds into the core language some convenient additional list manipulation functions, has powerful new capabilities for string and sequence comparison, and introduces fully integrated, zero configuration, multiparadigm parallel computing for multicore and network systems.
