 We are trying to work out what is the most recent version we can update to while making it so all devs can still develop using the version on their OS/distro.
 
+Developer testing with various GCC compiler and hardware versions demonstrates code stability, and helps suss out intermittent issues such as timing issues or uninitialized memory.  But, if the nightly build system uses a different GCC version from most developers, a developer-testing phase may be needed for future firmware release candidates before the worldwide release announcement.
