A quick note on old versions

[Kevin Hester]

Hi ya'll,

I've noticed in the analytics a lot of you are still using pretty old versions (and encountering bugs).  I'd highly recommend updating.  The current version in alpha test is 0.5.4.

As always: thanks for helping this project by testing.  This mail list isn't used too much anymore, I mostly post on the forum: https://meshtastic.discourse.group/t/android-app-new-releases/78/18
