The Mathematica 7 Release

Mathematica 7 was released today (okay, late last night). It has been under active development for 18 months. While not as gigantic in scope as Mathematica 6, it’s still a very solid, feature-filled upgrade.

The headlining features for version 7 are:

A list of all major new features is available here. In addition to the highly publicized features, here is an incomplete list of other improvements I worked on for this release:

  • QuickLook plugin provides previews for notebook documents on Mac OS X 10.5
  • text & cell selections use system highlight color rather than XOR drawing
  • better sub-pixel accuracy of screen drawing & vector graphics export
  • BezierCurve support for EPS & PDF Export, and PDF Import
  • PDF export can attach arbitrary files (including the source notebook) to the exported PDF file
  • PDF import can read file attachments
  • PDF import of encrypted files works with default (empty) or user-supplied password
  • decreased EPS & PDF export file sizes in some cases
  • decreased notebook file sizes in some cases
  • ControllerState supports MIDI devices (e.g. keyboards, mixers, etc.) on Mac OS X

Additionally, the minimum Mac OS X version increased from 10.3 to 10.4.
