Well , since we are in phase of testing , I created this post so that every time that Microsoft will release a new build of the dashboard , it will be added to the list created in this post together the date of issue and the changelog of single build , always assuming that you will understand what has changed , we say that this also serves as a help to decide for future leaks, always and only if , the build has a enough substantial changes . If the update case problem of red ring of death , this can be reported on this post . In this way there will be no more senseless leak.
Yes, the new Dashboards CAN cause the RROD to some people. It happened to 5 people and they've confirmed it in the BETA forums. Microsoft are making them pay to fix it, it's due to an update glitch whilst installing.
The chances of RROD is very slim The team always test these updates before releasing to the public, so that it can be confirmed to be working.
