Finally it's good enough to release. Following the strict swfdec-does-not-crash policy, here's a completely fixed up backend to make all your Flash madness possible. swfdec-0.5.0 "Meet Plan Party!" http://swfdec.freedesktop.org/download/swfdec/0.5/swfdec-0.5.0.tar.gz MD5: 53c9dd7f87ec9a73277ceb4d7c033a3c swfdec-mozilla-0.5.0 "Destroy all the old prints in celebration" http://swfdec.freedesktop.org/download/swfdec-mozilla/0.4/swfdec-mozilla-0.5.0.tar.gz MD5: 81f5d05c2677995611eac1742f025e2d As noted above, a lot of work was put into the backend, in particular the Actionscript interpreter, which was completely replaced. The new interpreter is a lot more correct and is close to playing script-heavy Flash files like [1]. It's also way smaller than the old Mozilla-Spidermonkey script engine. For more new features see the changelog and news file. Of course new code means new bugs. Nonetheless, Swfdec should be very stable and not crash your browser. In the unlikely event of it doing this, please immediately file a bug at https://bugs.freedesktop.org.
