We're monitoring crash reports closely and will be addressing them as quickly as we can. To that end, we've published the first update (1.1.1, build 41) for our Beta users; it will be available for download shortly.

Release notes (if any specific notes are applicable) are in the update itself, although expect "Stability fixes" to pretty much cover it.  For beta, we're not looking for confirmation that a specific crash is fixed - in most cases we can't give you steps to reproduce the individual crash.  This is just a sanity check before public release.
