As of today, the Bugs section is closed, and bugs should now be reported with the <a href="http://www.sf.net/projects/cdk">CDK project</a>. Category "jchempaint" should be used. The reason is that JChemPaint's source code is now fully integrated into the CDK project.

The third development release (2.1.2) has been released.
Like 2.1.1 it is the product of a week of hacking at it in a JChemPaint Workshop at the CUBIC.

About a year ago (10 May 2004) JChemPaint 2.0 was released, and today, as a product of the fine hacking meeting at the CUBIC, the first release of the development branch is out: 2.1.0. Except many things to be broken, but it gives a good idea where things are going. And make sure to check out the documents written down during meeting last week.

This release does not contain bug fixes, but it sure does make drawing molecules a lot more pleasent.

A JChemPaint hacking workshop will start on April 25th, 2005, at Cologne University Bioinformatics Center (CUBIC). Virtual participant are highly welcome.
The goal is to move JCP to the CDK hierarchy, create a convenient but flexible build system, write some roadmaps and do as much of the roadmap items as possible.
On major topic will be an applet of decent size.
Please show up on IRC (irc.freenode.net #cdk) if you are interested in participating.

The recent JChemPaint releases have been strongly depending on the CDK library, thus it was a logical choice to move those project further together to speed up development. Both the website and the source code is being integrated right now. More on this later.

The biggest change in the 2.0.11 release is the support for radicals. Editing, saving as CML2 and reading from CML2 and MDL files was added.

The new release drops the inline DADML support in favor of the new DadmlBrowser plugin. It offers a more informative GUI listing all information it finds instead just the structure of the first it finds.

A minor bugfix release was build fixing problems with depiction of aromatic rings, and processing of SMILES with dots.

JChemPaint 2.0.7 has just been released. It carries the LGPL license, as JChemPaint does earlier. It used GPL for some time to trigger more patches from users, but this did not happen. Since all functionality was in CDK and thus LGPL already, it's not really a big deal.

While development has started for a better designed JChemPaint (still based on CDK, of course), a new bug fix release is out. JChemPaint is a Java program for drawing 2D chemical structures like those found in most chemistry textbooks. It is based on the Chemistry Development Kit (cdk.sf.net). The GUI is licensed GPL, for the algorithms in CDK are licensed LGPL.

The size of the applet jar of the 2.0.7 viewer only applet is reduced to half: 823 kB, instead of 1.6 MB.
A demo is online at: http://jchempaint.sourceforge.net/applet-2.0.7/

A new JCP release is out, which no longer relayouts after saving SVG, can open files from the command line and has new windows maximized by default.

In addition to this new dotdot release, also new Debian packages have been released.

Bugfix release 2.0.3 contains a few small code cleanups with allows easier use as an applet, and contains a improvement of the SMILES parsing algorihm, fixing three reported bugs.

A preview is put on the website showing what a JChemPaint applet could look like. Go to http://jchempaint.sf.net/applet/

Rendering was improved with anti-aliasing and a dialog for setting rendering options, including setting of the font. Furthermore a few bug fixes.

This release fixed closing of plugins before the program itself was closed, made a number of speed improvements, added the missing Atom popup menu item string, and grayed out the pop menu titles. It is compiled against CDK from CVS, which contains a CDKEditBus update, improved CML2 and SVG output, a partial INChI reader, and a few minor bugfixes.

First stable release of JChemPaint based on CDK. It is not without bugs, but very useful already, and improves the 1.2.1 version in several areas. The GUI has translation in Dutch, French, Polish and German.

One of the last beta phase releases of JChemPaint is out: 1.9.11. This release is mostly a bug fix release, and also includes other minor improvements, like a more efficient Rendering engine and a GUI periodic table for selecting the drawing element. JChemPaint is a Java 2 program for drawing 2D chemical structures like those found in most chemistry textbooks.

Release 1.9.10 is the last beta version to be released. The new JChemPaint is close enough to the 1.2.1 release in functionality to be able to say that the next release will be the next stable JChemPaint release.

We published our second beta release, 1.9.9. This means we are approaching a stable release.

Version 1.9.8 is the first beta release, meaning that new features are harder to drop in at this stage and that focus is on bugfixing.

Today the last alpha release of JChemPaint 2.0 has been released. This means, that from now on
mostly bugfixes are applied and no major new features are added.
