The JCP 3.0.1 release is available. This is a bugfix release for 3.0. Download at http://sourceforge.net/projects/cdk/files/ or have a look at the changelog at http://cdk.svn.sourceforge.net/viewvc/cdk/jchempaint/branches/3_0/changelog.txt?revision=15294 .
We have finished the JCP 3.0 release. This is a totally reworked design, offering a really user friendly interface. We have also done thorough testing and are confident this is a better and more stable release than ever. The applet is also signed so that it can do IO etc. and is smaller and faster than ever. Please find downloads at https://sourceforge.net/projects/cdk/files/ and a test page for the applet at http://www.ebi.ac.uk/steinbeck-srv/jchempaint-nightly/EditorApplet.html
As reported on cdk-user:
as I write, CDK 1.2.3, also know as the 'Don't use this Renderer'
release is finally being uploaded to SourceForge... it fixes a few
things (see below), but most importantly, it removes a few Renderer
classes which should have been removed before the 1.2.0 release.
As you might know, the 2D renderer is undergoing a major rewrite which
is used in JChemPaint 3.0 (based on the JChemPaint 2.5 development
series) and Bioclipse 2.0.0. The code of this renderer is available at
 and will be rewritten as clean patches to the CDK 1.2.x branch
during this summer. Before that, it is a bit of a hassle to get things
going, but as the JChemPaint 2.5.x and Bioclipse 2.0 betas show, not
impossible.... read more
Read it in the cdk-user ML archives:
Last week the a release candidate for CDK 1.2 was released:
A bug fix release 1.0.4 and a second developers release 1.1.0 have recently been released. Get them from SourceForge.net.
Today a branch for the planned CDK 1.2 release later this year has been made in SVN.
Second bug fix release for the CDK 1.0 branch. The SMARTS module was too unstable, while fixes required Java5 syntax. It was removed. Furthermore, several bug fixes have been applied.
CDK 1.0.1 was just release, consisting of mostly some bug fixes, but also Java 1.4.2 compile problem fixes and work on the SMARTS parser.
A milestone indeed.
