We are pleased to announce a new production release of the Root system. The release is stamped 2.20/06. This new release includes a long list of tiny improvements and a few bug fixes. See the release notes for more details. The following is a summary of the main features of this new version. - TrueType Fonts package introduced on Unix (except AIX). The TTF package provides better quality scalable fonts. For the definitive guide on how to use the TT fonts with ROOT see the web page: http://root.cern.ch/root/TrueType.html. - New class TClassTree. Draw inheritance tree for a list of classes The following options are supported - Direct inheritance (default) - Multiple inheritance - Composition - References - New class TTreeViewer A graphical front-end to TTree::Draw and Scan. See extensive documentation in the class. - Additional functionality in class TTimer. - Possibility to notify any TObject without deriving from TTimer. - Possibility to execute an interpreted command/macro at time-out. - Several new functions in class TRandom (see class for more details and also some benchmarks). - New functions for random number generation in TF1, TF2 and TF3. - Several new functions in TMath. - Zoom with the mouse on axis. - New functionality in TDirectory (see ReadKeys and SaveSelf). - Add a new test program called "stress" in test directory. This program can be compiled with the native compiler or interpreted. The program stress is a collection of test programs executed sequentially and testing most of the facets of the Root system. The execution of stress ranges from a few tens of seconds on fast systems to a few minutes. The execution time is used as a benchmark. We expect to add more test programs to the stress test suite. - Add functionality to save GIF files from displays with more than 8 color planes. - Added transparent pads. - New makefiles. CERN is closing this evening until January 4. Merry Christmas to everybody. Rene Brun & Fons Rademakers
