That's great, Max! I've been using the 6.4 beta for some time now.

Question: Why is there an update to 6.4 beta with 6.4 just released?

There are two Android apps - "XCSoar" (the blue one) and
"XCSoar-testing" (the red one). Both "XCSoar" and "XCSoar-testing"
are now 6.4. Previously, they were 6.3.11 (old stable) and 6.4_beta2.
Soon, "XCSoar-testing" will become 6.5_preview (when 6.5 development
begins), and "XCSoar" will become 6.4.1 (bug fixes).
