MacVector Inc have released a free version of MacVector.
If you used a temporary trial license, then when the 21 days were up, MacVector would simply refuse to start unless you entered a new valid license code. With the release of MacVector 12.7 we have changed that behavior. Now, when the trial license (or any annual license) expires, MacVector will give you the option of continuing to work, but with reduced functionality. All of the functions in the Analyze menu become disabled, but you can still open, edit, save and print MacVector documents, or save MacVector files in other formats.
ichemlabs have announced the release of ChemDoodle Web Components 5.
ChemDoodle Web Components 5 is a massive update. The most notable addition is a Full Sketcher, for drawing multiple molecules, shapes and figures, in addition to the Single Molecule Sketcher already provided. iChemLabs Cloud services and the ChemDoodle JSON format have been updated and drastically improved. The entire codebase has been reoptimized and cleaned, doubling the performance in desktop browsers and more than quadrupling the performance in mobile browsers. All Canvases now handle managing multiple molecules and shapes. Many new additions have been added and dozens of bug fixes have been implemented. We will be unrolling our new proprietary options over the next month, but of course, everything is available for free today under the GPL license!
There is a tutorial for using ChemDoodle web components here.
