// STABLE 
When we believe we have a particularly good build, we promote it to the stable channel. 
We intend to do this more or less every quarter, but this may vary. We recommend that you use this channel for all production app releases. 
We may ship hotfixes to the stable channel for high-priority bugs, although our intent is to do this rarely.

// MASTER 
The current tip-of-tree, absolute latest cutting edge build. 
The channel master has the most recent build. 
No tests were run before build so there might be broken functionality when using this channel.
