= Release Notes for Version 1.6.8 include::release-head.adoc[] :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.
