1 = Release Notes for Version 1.8.1

5 Version 1.8.1 includes an important bug fix for Apogee Lockout
6 operation in all flight computers. Anyone using this option
9 This release also contains a change in how flight computers
10 with accelerometers deal with speeds around and above Mach
11 1. In previous versions, the flight computer would completely
12 disregard the barometric sensor above 330m/s (around Mach
13 1). Now, the data from the barometric sensor is reduced in
14 effect without ever going away entirely. This prevents early
15 drogue deployment for flights which spend considerable time
18 1.8.1 also contains a couple of minor fixes for AltosUI when
19 analyzing saved data files.
25 * Handle time value wrapping in Apogee Lockout
26 correctly. Without this, apogee lockout would sometimes
27 prevent any drogue charge from firing.
29 * Change Kalman filter on flight computers with accelerometer
30 to continue using the barometric sensor even at high speeds
31 to avoid unintentional drogue deployment during
34 == AltosUI and TeleGPS Applications
38 * Add new 'Huge' font size to make text even bigger on high
43 * Prevent some crashes when reading older saved flight data
44 for graphing or KML export.
46 * Load frequency preference at startup. The loading code was
47 broken, so you'd see only the default frequencies.
