jQuery is now available, exclusively, under the MIT License. This license is much more open than the previous Creative Commons license used (and much better suited to software development). In a nutshell, for those not familiar with the MIT License, it’s about as free as you can get without actually putting something in the public domain. The only stipulation is that you keep the copyright along with the source code, and everything will be a-ok. Choosing this license was the result of a long discussion on the mailing list, figuring out what was best for everyone, including all the corporations that wanted to use it. If you have any questions as to how this might effect you (note: It probably won’t), just drop a note to the mailing list and we can help to set you straight.
