I've posted an updated release candidate 1b for Boomer today, and you can download it from the files area.
The only remaining known P1-P3 issues in this release are a problem that affects users of TX (Trusted Extensions) and lack of BFU support. Obviously we're feeling pretty good about this release, and we're on track for integration in b115.
As usual issues should be reported using the Bugster category development/audio-ng/software. Alternatively, you can send mail to email@example.com.
