From the release notes:
- New implementation of the gas needs calculation.
ATTENTION: The previous code tended to over-estimate the gas needs for a particular dive. This new implementation delivers lower, but thus tighter figures. If the previous calculation results fitted with your practical gas consumptions, then your SAC (usage rates) were probably set lower on the OSTC than they actually are. In this case it is strongly advised to set the usage rates to a higher value until matching between calculated forecasts and actual use has been established again.
- The TTS does not include any extra minutes for a slowed final ascent from last stop to surface any more. Still it is recommended to do this final ascent at a much slower rate than the standard 10 meters per minute. One meter per minute would be good. Remember: tissue saturation peaks in the moment of reaching the surface.
- The behavior and the naming of the "extended stops" option has been slightly modified since the first implementation with firmware version 3.03.3.
- On a deco dive, once the last stop has cleared and the NDL time comes on again, a "slow" reminder will be shown to remind on doing the final ascent >>slow<<.
- On firmwares enabled for helium, the current gas density will be shown in one of the custom views now. The gas density is computed by current mix and depth.
When in CCR or pSCR mode, it also figures in the current ppO2 / setpoint value. The unit is grams per volume of one liter at current pressure.
- All "stops" that are scheduled for gas changing only, but not require a real stopping, are now displayed with a duration reading ".." (double dots). Like in writing ... means "and so on", the double-dots shall symbol that you can go on with your ascent.
- While charging, charging progress is shown on the screen now.
- 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).
Set up gases as follows:
Single gas dive:
set gas to use as 'first' and all other gases to 'disabled'.
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'.
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'.
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!
- 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.
- In the simulator, the +5 minutes function can now be triggered in succession without needing to reopen the options menu each time.
- The French and Italian language package has been upgraded.
- 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'!
- 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.
- 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.
- OSTC TR: pressure logging has been implemented. Logged pressure data can be retrieved by downloading the logbook data using external logbook software.
- 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!
- 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.
