[1.6.5] with RTE 3.20 FIX: Update 1.6.4 could cause problems when the "Big Font" default view was preset to "Decoplan". The menu entry "Big Font" in SYS2 could freeze the OSTC4 in surface mode
[1.6.4] with RTE 3.20 CHG: Deactivation of the 'fallback' option when the CCR mode is set to 'Fixed' - this makes it a little clearer that the option has no influence in this mode. NEW: CCR overview in surface mode. Makes it easy to quickly check that all settings (mode, setpoints, diluent, scrubber timer) are correct when preparing to dive (also makes the OC gas list available in surface mode for the same reason). CHG: Revised automatic setpoint change. The proposed approach is essentially the approach used by most controllers of eCCR ('upshift' on descent, 'downshift' on ascent), so that the OSTC4 when used as a backup computer for eCCR will make the changes at the same time as the eCCR itself. CHG: Enhancements with the compass. Delete bearing and reset to land based bearing, Add support for a configurable compass declination in a range of -99 to 99 degrees. NEW: Added UART multiplexer support for DiveO2: The existing autodetect function now includes a UART multiplexer. The datastructures and protocol handling has been adapted to support several DiveO2 sensors connected to the UART. NEW: Define explicit setpoints for low / high / deco. Add an option to delay the switch to SPlow until all decompression has been cleared. NEW: Adds a simple countdown timer, available as a custom view in surface and dive mode. This can be used to time safety stops, or to prebreathe a CCR (or to boil your breakfast eggs if you are so inclined). The duration of the timer is configurable from 1 second to 9:59 minutes in the System menu. The timer is started by switching to the custom view, and remaining on it until a 10 second delay has elapsed. Once the timer has started the custom view can be changed and the timer will continue running in the background. After the timer has run out 'Finished' will be shown for 10 seconds in the timer custom view, and then automatic switching of custom views (if configured) resumes. In surface mode the dive computer will not go to sleep while the timer is running, and a mini timer will be shown when the timer custom view is not showing. Fix: Fix a bug that disables arbitrary menu lines in dive mode if lines are disabled / inactive in surface mode. Fix: Bugfix CustomView selection during dive mode: The CustomView selection during dive mode was limited to two pages, while meanwhile three are needed to show all options. The problem did not showup in surface mode selection. Rootcause was a static definition instead of the dynamic one used in surface mode. In addition with every page shift a new page was created which might cause display errors after some times. To solve this the pages are now updated instead of rebuilding the pages.
[1.6.2] with RTE 3.10 CHG: Allow dates >2022 to be set in the menu NEW: Support for DiveO2 Solid-State-Oxygen sensor NEW: Sensor autodetect allows combination of one solid-state sensor and up to two analog sensors FIX: Bugfix compass bearing: In previous version an invalid value was set in case the bearing was set without compass calibration. Rootcause was that the bearing -1 is received in case the compase is not calibrated. This has been fixed by setting bearing to 0 (360) in that case. NEW: Extension scrubber time: In previous version only one scrubber timer was available. After movement of scrubber timer menu menu space became available allowing to upgrade the functionality to support two scrubbers. To make it easier to identify combination ID to used scrubber the date of the last usage of the scrubber timer has been added. NEW: Added new info page for extended sensor data: The new source file may be used to create a information page individual for every smart sensor type. The DiveO2 sensor is the first supported sensor NEW: Show saturation in large font view: In case the DecoTTS custom view is active then the saturation will be displayed if the diver is close to the surface (TTS < 1 minute). FIX: invalid setpoint (0.0) was used after switch from CCR to extra (OC) gas NEW: Add mini compass with marker declination indication selectable in dive mode NEW: Enable start dive in Big font display: The diver had to manually switch to the big font view in dive mode. By selecting the big font view as default view in the custom menu the BF view will now be shown from the start of the dive. In order to have a qucker access to the settings menu, the settings menu has been added to the quick menu selection. The settings menu will then also be left to the BF view. NEW: Added button lock after wakeup in surface mode: During setup of diveequipment the OSTC4 is sometimes operated unintended (e.g. while equipping the jaket). To avoid this it is now possible to activate a button lock in the button lock sensitivity menu. The OSTC4 will then wakeup as usual but if the diver wants to oerate the menus he has to press the buttons in a certain order. The button to be pressed is indicated by a blue bar. The button lock is deactivated in dive mode. NEW: Quit simualted dives after the dive time set in the SIM tab. NEW: After a firmware update, use the factory settings for button sensitivity if these exist, the default settings otherwise. The factory settings for the buttons can be updated in the System menu / Reset menu / Maintenance / 'Store button factory defaults'.
[1.6.0] with RTE 2.09 FIX: automatic switch to o2 sensor custom view: In surface mode the custom view will automatically switch to the o2 sensor view in case the OSTC4 is set to sensor mode. This was also done in case the o2 sensor view was deactivated. This lead to a automatic switch to e.g. compass what was not intended. In the new version the automatic switching is deactivated in case the custom view is deactivated CHG: Ignore automatic setpoint changes during ascend: In the previous version setpoint changes which have been configured for descending were considered for deco calculation in case one or more additional diluents have been activated. This procedure does not fit to the common way to keep setpoint high till end of the dive in order to get rid of the deco time. In the new implementation the OSTC 4 assumes that the current setpoint is used till the end of the dive. FIX: Bugfix low ppO2 warning in bailout mode: the code has different sources for divesettings (real and simulated). The ppo2 calculation code used the pointer to the real structure. As result in simulation mode an error occured caused by the ppo2 calculation which was not aware that a bailout happened (because the real structure was references instead of the simulator ones). The problem has been fixed by using the "stateUsed" pointer which is refering to the structure currenty in use. FIX: Battery charge complete event: In previous version it could happen that the battery charge state was set to 100% even the battery was not completly charged. Rootcause was that the external charger IC signals sometimes completion because e.g. the connection between charger unit and OSTC is disconnected within a short time slot. This may happen while the user is trying to get the OSTC in a good charging position. To avoid this the state machine now checks the voltage everytime for valid charging complete range before a charging complete is signaled.
[1.5.9] with RTE 2.07 NEW: Added Charging view: In case the charger is connected to the OSTC a new menu will be shown in the customer view section. The new view shows a charging current indicator, the current charge percentage and an estimation how long the completion of the charging cycle will take (hour window). NEW: PSCR Mode NEW: Scrubber Timer tracks use of CCR scrubber CHANGE: Allow setpoint starting at 0.4 ppO2: Some rebreathers (e.g. Sentinel) start with a ppO2 of 0.4 Bar => modified range check to allow this value (was 0.5 before) NEW: Introduced new menu tab "OP" for additional CCR options, e.g. The Scrubber timer and PSCR parameters
[1.5.6] with RTE 2.06 NEW: O2 calibration for analog sensors FIX: At the begin of the dive and while switching between T7 <=> T3 view a primary view could be shown which was deactivated by the selection dialogue. In case the primary view is now deactivated, the next activated view will be shown instead FIX: Compass accuracy for some hardware versions CHG: Handle analog O2 sensor voltages outside reasonable parameters as invalid CHG: In surface mode the custom view will now reset to the o2 sensor display if sensors are connected and no button has been pressed for 20 seconds
[1.5.5] with RTE 2.05 NEW: SYS3 menu where all custom views can be configured in detail (center, corner and big font) FIX: Disable compass properly when not in use (end-2019 hardware only) NEW: Added new option to gas configuration: "Off" (These are then not shown in the custom gas list) FIX: Startup behaviour in cases where incorrectly stored dives are in the internal logbook
[1.5.4] with RTE 2.04 FIX: support for some old harwdare versions was broken in 1.5.3 (Only serial number <100 were affected) CHG: layout in internal logbook cleaned CHG: Only switch between "no fly" and "desaturation" in case there is desaturation time left FIX: Balance value of button responsitivness were not considered during firmware startup CHG: internal improvements in sleep mode FIX: use dummy profile if necessary (If there are corrupted dives in the logbook)
[1.5.3] with RTE 2.03 CHG: Always show battery voltage in surface mode CHG: battery status is now preserved for future updates NEW: Support for much faster updates (With OSTC companion 3.2 and later) FIX: (very) short screen lag removed during sample storage in dive mode
[1.5.2] with RTE 2.02 Beta Version! FIX: display of time of minimum voltage FIX: Display of Sensor values. At divestart sensor values were shown even sensors were deactivated (fix SP) FIX: Bugfix invalid voltage / temperature after coldstart FIX: Instant dive start at several meters out of sleep mode (Jumping into the water) may resulted in lagged/freeze depth reading CHG: Speed increase of Bluetooth communications CHG: Look and Feel for Gauge/Apnea mode with flipped screen improved FIX: Deco warning after Gauge mode FIX: Download issues of corrupted dives FIX: Proper logbook write (Very spurious error, mainly in CCR mode)

[3.19] MD5: 9e79db5fa4f2f72086ce83abd3ee279f BUGFIX: Increase resolution of tissue pressure calculations to track very low pressure differences between ambient and tissue pressures CHANGE: OSTC with mechanical (magnetic) buttons need both buttons beeing pressed to wake up CHANGE: Support for new OSTC+ hardware with O2 sensor inputs CHANGE: Adjust max. brightness settings CHANGE: reset planning parameters to default values - only when entering the menu, thus keeping the settings between multiple calculator runs FIX: the output of the calculation results was divided into several steps, which could be interrupted in cooperative multitasking. So glitches could occur in the 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 interrupted.
[3.18] MD5: c1720d0eb4b59c411e4dc2fe1862403b BUGFIX: Properly update desaturation time and tissue data after battery change (OSTC with user-replaceable batteries only) NEW: Option to suppress non-critical warnings in dive mode CHANGE: Do not present gas6 option in alternative layout (Switch to normal layout in order to configure the gas 6 during the dive) CHANGE: Do not show RX portions of tank setup menu when there is no RX hardware CHANGE: Low-level code improvements for performance

[3.12] MD5: 610b57b2998cfe300a97eab8cd776d18 BUGFIX: Deco paramters (Saturation/Desaturation) were shown false in the logbook and surface screen (Non-GF deco mode only) BUGFIX/CHANGE: Saturation/Desaturation parameters are moved into thier own Sub-menu (Non-GF deco mode only) BUGFIX: Screen startup behaviour (OLED Limited Edition only)

[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)

[3.06] 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.

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.

[10.66] 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
