Here are some quick download statistics for some of the chemblaics components. First Jmol. The new stable Jmol 10.2 was release just over a week ago, and this obviously boosted downloads, breaking the monthly download total of two earlier this year (source): Statistics for the CDK include download numbers for the CDK library itself, but for JChemPaint, the CDK News, and several other packages too. Totals are at about 1/3rd of Jmol.
