We're planning to release the new version towards the end of March, there're still improvements we'd like to make.
There will be opportunities to try early releases of SQL Search, for example we're keen to check the upgrade experience is smooth. If you'd like to try these early builds then please send me a PM with your e-mail address.
The build for Lemosj was to fix the specific problem he was experiencing, but there were no new features in that build. And I'd prefer it was not widely distributed because it may prove incompatible with future releases.
