Change History
Changes made from version 8.00 to 10.40:
Fixes a crash that can occur when changing the depth of an automatic CCR setpoint switch.
Fixes ascent rate being calculated incorrectly when updating at a rate faster than once per second, such as in Apnea activities.
Fixes how Bottom Time is rounded in the dive log details to match the Garmin Dive app.
IN-DIVE CHANGE: Changed the behavior of dive compass Set to Recip., Set to 90L, and Set to 90R to set the new heading offset from the original heading instead of the current heading.

IN-DIVE CHANGE: Added â??Bail-out to Diluentâ?? option if no open-circuit cases are set up in a CCR dive.
IN-DIVE CHANGE: Fixed an issue where, in a CCR dive, the PO2 was being incorrectly calculated as the maximum of the diluent's PO2 or the current setpoint. This error could occur when diving in a situation where a diluent flush would actually raise the PO2 of the loop.
IN-DIVE CHANGE: In the CCR app, the current PO2 value will now blink yellow if the diluent PO2 is below 0.18.
Added a setting to enable the UP key while in-dive (Dive Setup > UP Key).
