[3.10]
MD5: 3a2e43381ce352f785096810cad19a33
- Hardened all USB/Bluetooth communication against data losses and timeouts
- 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 V3.09 beta 4 (or later) is already on the unit.
- New option to acknowledge the most recent warning in dive mode (Left press -> Ackn?)
- Removed option 'ascent speed', ascent calculation is done with a fixed
  speed of 10 meters/minute now (equals the ascent speed limit by Bühlmann).
- Improved calculation accuracy of the initial ascent. Remark: this will
  have a slight impact on the resulting deco schedule compared to firmware
  3.08.
- The deco calculator now figures in the salinity setting.
- Aligned logbook and last dive summery of avg and max depth regarding
  rounding and incorporation of salinity setting.
- Done some fine-tuning of depth outputs when using imperial units (feet).
- In dive mode, sometimes the temperature was not shown any more after a
  gas change - fixed now.
- 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.
- 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.
- Fixed the urge of the better gas hint to always favor one specific gas
  out of a set of two or more gases that have the same change depth.
- For dives done on firmware >= 3.08 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).
- As long as a gas or diluent is currently selected as breathed, it can
  not be set into the lost state any more.
- When changing the battery or doing a cold start, the current CNS value
  does not get lost any more.
- 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).
- 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.
- Internal improvement: the code for the internal storage system and for
  the communication system (firmware uploading, dive data downloading)
  has been re-factored to secure maintainability for the next years to come.
- Internal improvement: the scheduler for the dive mode calculation plans
  (fTTS, bailout) has been completely rewritten for better maintainability.

[3.08]
MD5: aa73b8aad928d4a827a97978027ab726
BUGFIX: "Sticky" button behaviour on some hardware versions (Only OSTC 2 (2017), TR and OSTC plus)

[3.07]
MD5: 4ee3a98b70f73c1d1aa11d5b91e2f70f
BUGFIX: Add surface part at end of dive to surface interval properly
BUGFIX: Average depth in logbook did not took salinity setting into account
CHANGE: Change color of temperature values in logbook to yellow

[3.06]
MD5: 6f6e2bf49297f359459aac2b2a90115a
BUGFIX: Hardware versions 13-xx-xx and 58-xx-xx could hang up with single-language versions of 3.03 or 3.05

[3.05]
MD5: 2fcfaa793b1bca51cb55f4e068bcd4a3

CHANGE: In the Tech version, max. ppO2 limits can now be adjusted up to 2.0 bar.
  Caution: know what you are doing! Recommended max settings are 1.4 bar for
  work gases and 1.6 bar for deco gases.
CHANGE: CCR mode diluent ppO2 versus setpoint check can be disabled now.
CHANGE: Fine tuning of the better gas cue behavior.
CHANGE: Improved smoothing of compass display.
NEW: Attention and warning thresholds for gas density put into the options
  table (adjustment via external software only, no mapping in OSTC menu
  as of now).
CHANGE: Renamed OC gas type 'normal' to 'work' (gas for the working phase of the
  dive). Along with this, it received a down-arrow symbol to depict it as
  a gas for use at depth, similar to the '=' symbol that was introduced some
  time ago to visually depict deco gases (imagine the horizontal lines as
  deco stops).

  EXAMPLE 1: Single gas dive:
  set gas to use as 'first' and all other gases to 'disabled'.

  EXAMPLE 2: Gas-change, extended no-stop dive:
  set gas to start with to 'first', all other gases to be used later in the dive
  to 'work' and the unused gases to 'disabled'.

  EXAMPLE 3: Deco-dive with one gas for descent & bottom phase, and deco gases:
  set bottom gas to 'first', deco gases to 'deco' and the unused to 'disabled'.

  EXAMPLE 4: Deco-dive with a deco gas used as travel gas on ascent, bottom, and deco gases:
  configure the deco gas twice: once as travel gas and once as deco dive. Set the
  same change depths for both instances and put the travel gas before the deco
  gas in the gas list (i.e: gas 1: travel, gas 2: work (bottom) gas, gases 3-5:
  deco gases). Set the travel gas to 'first', the bottom gas to 'work', and the
  deco gases to 'deco'. Take care to adjust the pressure available on the deco gas
  which is used for travel gas, too, to the amount of gas that is planned to remain
  after having drawn the travel portion from it!

CHANGE: When ppO2 is above normal threshold, but still inside the deco max threshold, and
  the dive has not yet progressed to doing the deco stops, the ppO2 warning has been
  degraded to an attention, i.e. associated messages appear in yellow now instead of
  red as before.
CHANGE: In the simulator, the +5 minutes function can now be triggered in succession without
  needing to reopen the options menu each time.
BUGFIX: Setting the change depth of the first gas to zero caused some unintended behavior.
  This is captured now. Anyhow, since firmware 3.2 it is required to set proper change
  depths for gases and diluents, including the ones set as 'first'!
CHANGE: The deco calculator now automatically picks the best gas suitable for the set bottom
  depth. If no suitable gas is found (i.e. configured), calculation will be aborted with
  an error message. By this change it is possible to calculate dives that use a travel
  gas (set as 'first') and a bottom gas (set as 'work'), as the deco calculator will now
  pick the proper bottom gas for calculating the bottom segment.
  Note: the deco calculator does not calculate the descent phase but actually spends all
  of the set bottom time at bottom depth. While this puts the deco calculation results
  on the safe side, beware that the needs on the travel gas will not show up in the gas
  needs calculation results.
CHANGE: OSTC TR: The timeouts for attentions and warnings in connection with discontinued
  reception of transmitter data have been relaxed a bit:
  - For up to 2 minutes without updating the last value received will be retained.
  - After 2 minutes without reception of any updates the pressure value will be marked
    as outdated.
  - After 4 minutes without reception of any updates a transmitter will be declared lost.
CHANGE: OSTC TR: pressure logging has been implemented. Logged pressure data can be retrieved
  by downloading the logbook data using external logbook software.
CHANGE: Descent speed in the simulator has been increased from 19 to 24 meters per minute.
  This speed is not configurable, nor the simulator's ascent speed of 9 meters/min!
CHANGE: In dive mode, the battery voltage will be shown when reaching 30%, and a warning will
  be issued when the percentage reaches 25% with 1.5 Volt batteries or 15% with LiIon
  batteries.
CHANGE: Added a hysteresis to the dive start / dive end depth threshold.
BUGFIX: Bugfix in none-helium compile variant.
NEW: Added an option "extended stops" (named "Gas Change/...before 1.Stop" in Deco Setup
  -> Deco Parameters -> more). If set to YES, a gas switch will be planned immediately
  on the change depth of the gas, even if a stop on that depth is not required by deco
  constraints. When set to NO, the gas switch will be planned to be done on the next
  regular deco stop.
  With extended stops enabled and a setting of "Gas Change (time):+0'" the switch will
  be planned with no actual halt at the change depth (i.e. "switch on the fly"). With
  change time set to > 0', a dedicated stop will be placed at the change depth for the
  given number of minutes. This gas change stop may not be needed by deco constraints,
  but it will influence the following deco stop depths and times as it introduces some
  added time at depth.
CHANGE: Complete rework of the alternative dive mode screen layout.
NEW: Included RX firmware update into tech version.
CHANGE: Reworked code for ascent and deco stops calculation. Does produce different results
  compared to the code used in 3.00.3! With this implementation of an GF-controlled
  deco schedule it becomes visible when deco stops disappear due to a high GF slope
  (difference between GF low and GF high) combined with a moderate depth of the first
  deco stop.
BUGFIX: When switching between GF and aGF, the depth of the first stop (determined by GF low)
  will be recalculated now.
NEW: New tissue graphics option (compile option as of now): shows absolute tissue pressures
  (N2 + He added) and saturation per tissue. In the saturation bargraphs, the green line
  marks GF low position, the yellow line GF high and the red one 100%.
BUGFIX: GF low can not be set higher than GF high any more as such a setting would produce
  an illogical deco schedule.
BUGFIX: In case the compass is not calibrated, the heading is now displayed as "---°"
  instead of ".00°".
BUGFIX: In the surface tissue graphics, tissues whose supersaturation exceed 100% are shown
  in red color now.
CHANGE: If any tissue is beyond 100%, no desaturation and no-fly times will be shown anymore.
BUGFIX: After use of the dive simulator and the deco calculator the interim tissue desaturation
  is catched up now.
NEW: Added support for display type 2.
CHANGE: The Deco Engine has been reworked to now run for up to 700 ms each second (configurable,
  800 ms may be feasible also), split into two compute chunks per second. This increases
  reactivity to buttons presses and compass display, while boosting deco calculation turn-
  around times significantly.
CHANGE: The simulator now uses the current ambient pressure as surface pressure instead of a fixed
  1.000 hPa as done before. So in mountain diving, when being at the dive site the simulator
  will show the same NDL times and deco schedules as will be shown in a real dive.
CHANGE: When exiting the surface menu, the return to the normal surface screen has been sped up
  and the display of the power-up logo screen is skipped now also.
CHANGE: When submerged, the unit will now proceed from surface mode display to dive mode display
  without intermediate display of the power-up logos.
NEW: A cue is given when it is time to go up to th next deco stop by highlighting the next stop
  data until ascent is done.
BUGFIX: When being shallower than the indicated stop depth, i.e. because the deco needs to be
  accelerated, the reduced ambient pressure is figured in into the deco calculations such
  that the displayed stop time, TTS and gas needs do immediately reflect the reduced depth.
BUGFIX: When set to imperial units, all depth will be shown in feet now not only in dive mode but
  also throughout the whole surface menus.
BUGFIX: When in a leap year, the 29th of February is now correctly handled when adjusting time and
  date on exactly that day.
BUGFIX: Bugfix: with the option 'always show ppO2' set, in CCR and pSCR mode a "Dil:x.xx" ppO2
  message was sometimes shown twice, once as an info and additionally as an attention or
  warning. This has been fixed now: in case of an active attention or warning the secondary
  info message gets suppressed.
BUGFIX:: the Simulator +5 min function had a punch-through effect on the real world last
  dive time (displayed surface interval).
BUGFIX: Tissue desaturation is now also computed while in surface and menu modes.

[2.99]

MD5: 51307831e6874c540ceaf8708ee73c0f

- 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.
