= Release Notes for Version 1.6.3 :toc!: :doctype: article Version 1.6.3 contains bug fixes for our host software on desktops, laptops an android devices along with BlueTooth support for Windows. == AltOS There aren't any significant bug fixes or new features in the flight firmware in version 1.6.3. == AltosUI and TeleGPS Applications AltosUI and TeleGPS New Features: * Add BlueTooth support for Windows operating system. This supports connections to TeleBT over BlueTooth rather than just USB. AltosUI and TeleGPS Fixes: * Change Java detection and install on Windows. Detection is now done by looking for the 'javaw.exe' program, and installation by opening a browser on the java.com web site. * Delay polling while the Fire Igniters is visible to allow for TeleMega to report back complete status over the radio. * Disallow changing RF calibration numbers in the configuration UI. There's no good reason to change this from the field, and recovering is really hard if you haven't written down the right number. * Fix USB device discovery on Mac OS X El Capitan. This makes the connected Altus Metrum USB devices appear again. == AltosDroid * Don't set target location if GPS hasn't locked yet. * Fix saving target states so they can be reloaded when the application restarts. When the application is shut down and restarted, all previous target state information will be restored (including GPS position if available). * Fix crash on some Android devices for offline maps when changing the map scale or location. == Documentation * Document TeleMega and EasyMega additional pyro channel continuity audio alert pattern.
