The PowerShell Team have made a number of interesting announcements recently:
Feedback is moving from Connect to User Voice
This is where you give your feedback and report bugs
For programmers the PowerShell reference assemblies are now available through Nuget.org
Meaning you can use Install-Package to get them. Assemblies for PowerShell versions 3.0, 4.0 and 5.0 are available
The tests the PowerShell Team uses to test new PowerShell builds are available on GitHub
