We've been hard at work over the last 7 months preparing a whole new core for Terminator and it's getting close to being ready, so this is a beta release intended for testing only. Ubuntu packages have been uploaded to our test PPA (https://launchpad.net/~gnome-terminator/+archive/test) and a tarball is available from http://mairukipa.tenshu.net/~cmsj/terminator/. Please provide any feedback about this release to our bug tracker at https://bugs.launchpad.net/terminator/ or our IRC channel, #terminator on irc.freenode.net.
Caveats: * config files from 0.14 and earlier are currently ignored by 0.90 because the config file format has changed. * we now have a very basic ability to save and restore layouts, but this feature is very new and likely to contain many bugs
