Eclipse 3.1 by the numbers

´┐ŻNumbers alone confer no advantage.´┐Ż
--Sun Tzu

Back by popular demand, here are some interesting statistics that highlight
the past year of development on Eclipse 3.1. All figures are for the Eclipse 3.1
development period only, from June 29, 2004, until June 28, 2005, and cover
only the Eclipse SDK components (Platform, JDT, and PDE), and their corresponding
newsgroups, mailing lists, and bugzilla products. Figures on the Eclipse source
code refer to the deployed SDK code, excluding all test and example code. The
download figure is a click count of download requests at, including
downloads served by mirrors. Direct access to mirrors, bit torent downloads,
and other download sharing are not included.

Compare with numbers for Eclipse 3.0.
