+<p>Version 1.9.9</p>
+</div>
+<div class="paragraph">
+<p>This release contains a critical bug fix for a problem
+introduced in version 1.9.8 for TeleMega and EasyMega
+boards. This problem occurs when using the stored
+configuration from 1.9.7 or earlier.</p>
+</div>
+<div class="paragraph">
+<p>If you are running 1.9.8 or are upgrading from 1.9.8 on any
+version of TeleMega or EasyMega, you must reconfigure all pyro
+channels, recalibrate accelerometers, reset the APRS interval,
+adjust the beep tone and reset the pyro time.</p>

+<ul>
+<li>
+<p>Fix EasyMega and TeleMega upgrade process from 1.9.7 or
+earlier. 1.9.8 introduced larger delay values, which
+required modifying the configuration in-place, and the 1.9.8
+version had a flaw which broke the pyro channel config and
+all of the config values beyond that in memory, including
+APRS interval, IMU accel calibation, beep tone and pyro
+time.</p>
+</li>
+<li>
+<p>Fix TeleMega v5.0 mag sensor driver. This driver was quite
+broken due to developing it in the presence of the magnetic
+beeper on the board. Because of that beeper, the values this
+sensor records are not accurate. Fortunately, they are not
+used for controlling the flight.</p>

+meant that the TeleMega v5.0 log files would cause an error
+when attempting to load them. Logs saved with AltosUI
+1.9.8 were not affected, only the presentation of the data
+was broken.</p>
