ChemWriter 3

ChemWriter 3, a major update to Metamolecular's chemical structure drawing and editing software, has been released. This new version, a complete rewrite, retains many of the best features of ChemWriter 2 while adding a few new ones, including:

Some important new features of ChemWriter 3 won't be immediately visible.

ChemWriter 3 was designed to take full advantage of HTML5 and new browser APIs that have begun to appear at a rapid pace. Because of the high cost of doing so while continuing to support dead-end browser technologies, ChemWriter 3 only supports Internet Explorer 9 and higher. Fortunately, ChemWriter 2 continues to remain fully compatible with IE6+.

Another goal was to create a platform that will enable the creation of custom ChemWriter extensions. Over the last few years, many people have requested features that, although clearly valuable, didn't make sense for the majority of ChemWriter's customer base. Because ChemWriter 2 was not written with extensibility as a major design goal there was no practical way to fulfill these requests.

In contrast, ChemWriter 3 was designed to support third-party developer extensions. The coming weeks will bring the first of what hopefully will be many JavaScript modules that extend the functionality of ChemWriter.

Trying out and deploying ChemWriter has never been easier. Gone is the need to separately download an SDK. You can create your first ChemWriter page in a matter of minutes by following the Quickstart.

ChemWriter 3 extends Metamolecular's commitment to enabling the Web browser as a first-class platform for interactive chemistry software. Whether you're an experienced ChemWriter user or a newcomer, I encourage you to head over to chemwriter.com and try it out.
