[Elecraft] K3 Beta Firmware Release -- MCU Revision 2.19

[Jon K Hellan]

Mine came with what looks like the latest beta at the time of shipping (2.11, I 
  think). Anyway, it's certainly newer than the latest regular release.

Is it recommended that I keep following the betas, or wait until one of the 
releases more recent than mine is declared "regular"?
