+:doctype: article
+
+ Version 1.6.8 fixes a TeleMega and TeleMetrum v2.0 bug where
+ the device could stop logging data and transmitting
+ telemetry in flight. All TeleMega v1.0, v2.0 and TeleMetrum
+ v2.0 users should update their flight firmware.
+
+ == AltOS
+
+ AltOS fixes:
+
+ * Fix STM32L DMA driver to work around STM32L SoC DMA priority
+ issue t lock-up in the logging or radio code, either of
+ which could stop data logging and telemetry.
+
+ * Avoid having TeleBT battery status values smash telemetry
+ packet data by holding a lock during both operations.
+
+ * Don't start reporting 'flight 0' when the log fills in
+ flight.
+
+ AltOS changes:
+
+ * Flash LEDS on all products briefly during power up so that
+ they can be tested during production.
+
+ == AltosUI, TeleGPS and AltosDroid Applications
+
+ AltosUI fixes:
+
+ * Re-enable go/no-go entries after they've been disabled due
+ to lack of data. If telemetry information is delayed when
+ the Ui starts up, sometimes important fields would get
+ disabled to never re-appear.
+
+ * Deal with ground station failure better during Configure
+ Ground Station operation by cleaning up pending operations.
