**************************************************
CHANGE DETECTED IN SERVER2 WITHOUT APP.YAML UPDATE
**************************************************
Maybe this is ok? Follow this simple guide:

Q: Does this change any data that might get stored?
  * Did you add/remove/update a field to a data source?
  * Did you add/remove/update some data that gets sent to templates?
  * Is this change to support a new feature in the templates?
  * Does this change include changes to templates?
Yes? Bump the middle version and zero out the end version, i.e. 2-5-2 -> 2-6-0.
     THIS WILL CAUSE THE CURRENTLY RUNNING SERVER TO STOP UPDATING.
     PUSH THE NEW VERSION ASAP.
No? Continue.
Q: Is this a non-trivial change to the server?
Yes? Bump the end version.
     Unlike above, the server will *not* stop updating.
No? Are you sure? How much do you bet? This can't be rolled back...

Q: Is this a spelling correction? New test? Better comments?
Yes? Ok fine. Ignore this warning.
No? I guess this presubmit check doesn't work.
