Yep, 3.0.beta10 is available here. So far, at least one person has compiled it successfully, so at least this release is already better then beta8. :)
Anyways, as stated in the release notes, this is the final beta release for 3.0. I’m planning on one release candidate which will have a working tcpbridge (which has been broken since moving all the editing code to libtcpedit) and then put out 3.0.0 shortly after that depending on any bugs people find.
Anyways, give it a try and let me know how it well works for you!
