(not a lawyer) It depends. Some jurisdictions give copyright holders more power than you might expect, if you used the software under the new license you might implicitly agree to such a term, and some licenses explicitly give the copyright holder revocation privileges. In a lot of places most open source licenses can't be revoked on a whim unless the person using them violated the terms. It's pretty common for communities to fork an old version when the parent project does something wonky with the license.
