 screen output if e.g. the TTS switched to NDL but the deco data flag vector was
 not updated yet. Now the compilation of all calculation results can no longer be

MD5: 33b70935590bc0c081b25d759e8dda34
BUGFIX: Improved calculation accuracy of the initial ascent. Remark: this will
  have a slight impact on the resulting deco schedule compared to firmware 10.64.
CHANGE: The menu system around setting up the dive mode & settings has been
  decluttered. All settings are now sorted into the groups dive setup,
  deco setup, SAC (gas needs) setup, ppO2 setup and stops & depths setup.
NEW: There is a new option "Swap on empty" in Dive Setup -> SAC Setup.
  It is only effective if "CalcGas(B/O)" is switched on, too. If both
  options are switched on, the deco calculation will switch to another
  tank (i.e. gas) once the tank of the current gas is calculated to be
  used up.
  This function can be used to automatically calculate a contingency in
  case of running out of a deco gas, as the deco calculation will then
  continue to calculate a deco making use of the spares from the another
  gases carried. Another application is with two or more tanks holding
  the same gas (i.e. independent double configuration, side-mount), as
  the calculations will then take the cumulative amount of gas carried
  into account before raising a gas needs attention or alarm.
NEW: For dives done on firmware >= 10.66 the logbook will have one more page
  showing the tissue pressures and supersaturation levels as of at the
  end of dive (i.e. when surfacing).
NEW: New option to acknowledge the most recent warning in dive mode
  (Left press -> Ackn?)
BUGFIX: Hardened all USB/Bluetooth communication against data losses and timeouts
NEW: A new Firmware Recovery Feature has been added: the currently active firmware
  can be backed-up and restored later on while other firmwares have been loaded
  thereafter. The feature is accessible via Settings -> System Settings ->
  Reset Menu -> Reboot and becomes available with the first firmware load after
  the 10.66 (or later) is already on the unit.
BUGFIX: During loading of a new firmware the clock will not loose time any more
  (on old firmware it became late by about 15 sec on each firmware update).
CHANGE: When run from a 3.6 V battery (either replaceable or built-in), the
  surface mode timeout is now extended to 4 minutes before going to sleep
  mode. If the OSTC is run from 1.5 V disposables, the timeout remains at
  the previous 90 seconds to save on battery runtime.
NEW: Updates OSTC 2 TR computers to RX-Firmware 1.40
