- GF low can not be set higher than GF high any more as such a setting would produce
  an illogical deco schedule.

- Moved positions of the GF values in the custom view such that 100/100 can be shown
  without numbers graphically overlapping.

- The resettable stop watch shown in the compass custom view now has both of its
  digits for the seconds shown as intended.

- As it will always be unknown how much power will exactly be available from a battery,
  the threshold for a battery low warning has been rised from 10% to 30%. When in dive
  mode, the display brightness will be set to ECO upon reaching this threshold, too, to
  conserve as much battery power as possible. Anyhow, when the battery warning comes on,
  it has to be expected that the OSTC may shut down without further notice at any time
  due to depleted battery. It is therefore strongly advised to not start a dive with a
  battery reading below 50%.

- The color-coding of the ppO2 shown in the custom view has been aligned with the color-
  coding used in the ppO2 warning and attention message.

- Fixed the erratic gas needs of 999 bar when current depth is shallower than the depth
  of the currently indicated stop.

- OSTC TR: in custom view 'measured pressure / SAC / needed pressure': if needed pressure is > 400 bar,
  display will show ">400" in warning color.

- Improved detection of charging-completed.

- Gases whose ppO2 at current depth is between ppO2 max "normal" and ppO2 max deco are now color-coded
  in yellow while not in deco yet (they were colored red before).

- Faster display response when changing deco-related parameters.

- Changed color coding of current GF (supersaturation) value:

  + GF factors enabled:
    - attention (yellow) if current GF value >= GF-high value
    - warning   (red   ) if current GF value >= 100%

  + none-GF mode:
    - attention (yellow) if current GF value >=  90%
    - warning   (red   ) if current GF value >= 100%

  => Resulting overall indications when violating a stop depth (in none-GF mode, 90% is used for GF_high):

  1) When shallower than indicated stop depth but still deeper than ceiling *):   Attention on stop depth        (yellow)

  2) When shallower than indicated stop depth and shallower than ceiling:         Warning   on stop depth        (red)
     As the current GF will be >= GF-high in this situation, additionally:        Attention on current GF factor (yellow)
                                                                                  Attention on depth             (yellow, blinking)

  3) When shallower than indicated stop depth and ceiling, and outside ZHL-model: Warning   on stop depth        (red)
                                                                                  Warning   on current GF factor (red)
                                                                                  Warning   on depth             (red, blinking)

     *) In GF mode, the ceiling depth is calculated at GF-high, in none-GF mode at 100% supersaturation.

- Updated calculation of ascent time:

  + When there is a ceiling but not yet a stop obligation (deco will vanish during ascent):

      ascent time = current depth / ascent speed                                    rounded up to next full minute

  + When in deco with indicated stops:

      ascent time =    (current depth - depth of last stop) / ascent speed          rounded up to next full minute
                    +  1 minute for each meter from depth of last stop to surface
                    +  sum of all stop times

  + when in deco with indicated stop(s) and shallower than the last stop:

      ascent time =    1 minute for each meter from current depth to surface
                    +  time of the pending stop(s)

- De-cluttered and ordered dive mode custom views by topics:

   1  average depth and stopwatch         - all modes
   2  compass                             - all modes
   3  ppO2 sensors                        - CCR & pSCR only
   4  sensor check                        - CCR  mode  only
   5  pSCR data                           - pSCR mode  only
   6  tank pressure and SAC rate          - OSTC TR    only
   7  gas needs for ascent                - deco modes only
   8  gas needs for return                - cave mode  only, not yet available
   9  deco plan                           - deco modes only
  10  ceiling, current GF and tissues     - deco modes only
  11  CNS values                          - deco modes only
  12  ppO2, END/EAD and CNS               - deco modes only
  13  GF factors                          - deco modes only
  14  clock, battery and surface pressure - all modes

                                            deco modes = OC, CCR and pSCR

- Eliminated a use of the GF-high parameter in none-GF mode.

- Improved rounding of first stop depth.

- Improved calculation of NDL time.

- Improved and streamlined calculation of CNS values at end of dive.

- Improved switch-over from being within NDL to being in deco, and vice-versa. A stop time of ".." minutes will be shown
  when there is already a ceiling obligation but deco calculation reveals that it will vanish during the ascent, given
  the ascent speed limit is obeyed.

- Fixed a bug in the calculation of the initial ascent.

- Made overall deco calculations once more a little bit faster.

- Stabilized timebase for blinking of setpoint display.

- Improved handling of the condition when a bailout plan can not be computed due to no breathable bailout gas available.

- Upfixed alternative divemode screen layout handling, fixed message suppression and automatic custom view switching in
  combination with alternative layout.

- Added an option for selecting if the max. depth or the average depth shall be shown in the main divemode screen.

- Improved stability of the timebases used for calculating the average depths.

- Removed erratic NDL outputs in gauge mode.

- Fixed display of resettable dive time when it exceeds 99 minutes, 59 seconds:
  + up to  99 mins, 59 sec display shows minutes:seconds
  + after 100 mins         display shows hours:minutes

- Improved energy saving by shutting down compass and accelerometer circuitry whenever compass is not shown.

- For those that like underwater navigation with compass: when the compass is shown, the temperature display will
  be replaced by a display of the resettable dive timer.

- When configuring a manually set gas while the dive ("gas 6"), it's display will be color-coded according to the
  set O2 ratio, the current depth and the ppO2 max thresholds, the latter automatically switching between normal
  and deco ppO2 max on dive condition. After adjustment of O2 and He ratios, the gas can be finally taken by
  selecting the "gas: xxx" item from the menu.

- The better gas cue is now also given when switching while the dive to the manually set gas ("gas 6"). As long as
  there is a regularly configured gas or diluent that fits for the current depth, a cue will be given towards this
  regular gas/diluent. This cue can be suppressed by setting the cued gas/dil as lost.

- The tissue graphics in dive mode now also displays the number of the leading tissue whenever the current gradient
  factor is > 0% or when in deco. (remaining todo: there is a light flicker in the output)

- Reworked the way the current firmware version and status (beta, release) is displayed, removed the "SP" notation.

- Known limitation: after 18 hours, 12 minutes and 16 seconds of dive time:
  + The average depths will show erroneous values.
  + The resettable dive time will wrap around to 0.
