+operation in all flight computers. Anyone using this option
+must update firmware.</p><p>This release also contains a change in how flight computers
+with accelerometers deal with speeds around and above Mach
+1. In previous versions, the flight computer would completely
+disregard the barometric sensor above 330m/s (around Mach
+1). Now, the data from the barometric sensor is reduced in
+effect without ever going away entirely. This prevents early
+drogue deployment for flights which spend considerable time
+above Mach 1.</p><p>1.8.1 also contains a couple of minor fixes for AltosUI when
+analyzing saved data files.</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_altos"></a>1. AltOS</h2></div></div></div><p>AltOS Bug Fixes</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
