[In-dive Change] (Mk2i Only) Added a Divers menu to the main menu during dive activities. This page allows you to view other divers’ tank pressures and depths.
[In-dive Change] In the compass menu, "Reset Heading" has been renamed to "Change Heading".
[In-dive Change] Improved Apnea activities to always show depth to a tenth of a meter, even below 100m.
[In-dive Change] Improved Multi-Gas to always show the PO2 field, even if the current gas is air.
(Mk2i Only) Added support for Descent T2 transmitters.
(Mk2i Only) Added support for public tank names, with supported Descent T2 software (2.05 or later). The name you assign to a transmitter is now visible to other divers when they pair, to make it easier to pair to the correct devices. When connected to another diver's transmitter, you can instead set a personal nickname for that transmitter. This isn't currently available for Descent T1, so they will continue to show the Device ID (numbers), as will Descent T2 devices with older software.
Added support for discarding Apnea activities. Apnea and Apnea Hunt no longer care about Pool Mode.
Added support for device backup and restore. Device backups happen automatically unless disabled, and upload to Connect for storage. You can apply a backup when setting up a new device or after resetting an existing Mk2 or Mk2S. If you purchase a Descent Mk3, you can migrate many of your settings forward from Mk2. For best results, make sure both devices are fully updated first.
Improved the ordering of the surface menu in Apnea activities.
(Mk2i Only) Improved how transmitter units are stored. Rather than PSI/Bar being set per-transmitter, there is now one setting for all transmitters.
(Mk2i Only) Improved transmitter software update prompts to occur at a more appropriate time.
(Mk2i Only) Fixed an issue where the main dive page would show a full tank if a transmitter was in a NO COMMs state.
Fixed an issue that could cause an incorrect warning about outdated watch or transmitter software when entering a dive precheck page.
Fixed the Obstacle Course Racing app being unavailable to add.
Fixed being unable to create courses on-device.
Fixed headphone names being blank in the sensor list.
Fixed an issue with the Spotify app always pushing the library page instead of the music control.
Brought Descent Mk2 up to date with Fenix 6 version 26.82 (from 25.10).
Fixed issue related to updating T2 software
- Fix issue when changing to Russian language

[IN-DIVE CHANGE] Fixed the CCR app showing a popup when the diluent’s PO2 was over the PO2 critical limit, when not bailed out.
[IN-DIVE CHANGE] While on the surface at the end of the dive, NDL will be replaced with the time until the dive saves (unless there is an alarm active or a deco/safety stop is required).
[IN-DIVE CHANGE] The safety stop broken alarm will no longer fire again if it already fired in the last 10 seconds.
[IN-DIVE CHANGE] The main dive screen will now continue to display the (paused) safety stop timer if above a missed safety stop, instead of displaying NDL time.

[IN-DIVE CHANGE] [Mk2i only] Added a second page to the Subwave network screen, showing approximate depths of other divers in the network.
[IN-DIVE CHANGE] Completely reworked the Apnea and Apnea Hunt apps: The in-dive screen and up to 5 surface screens are now customizable. The data screens have been reset for these two apps.
Pulled in changes from fenix 6X/s Pro through version 20.50. Major new features include the Adventure Race app, Sleep Score by Firstbeat, and updates to Garmin Pay.
Added the ability to view hang time, ascent, and descent statistics for Apnea dives in the dive log.
Added the ability to change the last decompression stop depth. You can now choose between 10/15/20 feet or 3/4.5/6 meters. This does not impact safety stops. This feature is also available in the Plan Dive app.
Added a “Pop-up” setting for dive depth and time alerts. Dive alerts with this setting off will tone/vibe and blink the depth or time field, but won’t show the normal popup. New alerts for Apnea/Apnea Hunt will default this setting to Off. Existing alerts, and new alerts for the other dive apps, will default this setting On.
Added a prompt to save if an Apnea/Apnea Hunt session hasn’t been saved 30 minutes after the last dive.
Added a simple stopwatch to the Apnea/Apnea Hunt surface loop.

Dive logs can now be deleted like other activities. Deleting a dive may cause dive numbers to get out of sync until the next sync with Connect.
Improved the No-fly time calculation to follow DAN’s most recent guidance: Single-day no-deco dive is 12 hours. Repetitive or multi-day no-deco dive is 18 hours. Decompression dive is 24 hours. Only dives deeper than 15 feet and longer than 3 minutes trigger no-fly restrictions. Missed decompression or gauge mode: 48 hours, as before. You can change back to the previous flat 24-hour timer by using the
Dive Setup > No Fly setting.
Improved Apnea/Apnea Hunt to always use every-second recording, regardless of the Data Recording setting.
Improved how Apnea activities calculate Time Out.

Back out a page to save the setting. Go back to Device Settings > General and toggle Physio TrueUp back on. Back out and sync your device. This will download your physio metrics from Connect and re-set your VO2 Max.

Brought in the changes made through version 15.20 of fenix 6S Pro. This adds the Ultra Run app, as well as several bug fixes.
Added another check for the depth sensor's health. Very bad temperatures will be considered a depth sensor failure and the "Do Not Dive" popup will appear (Temperatures don't factor in to generated dive profiles, but are an indicator that the pressure may also be bad.).
Improved how widget names are truncated on the reordering page, especially when using a language other than English.
Improved Bluetooth headphone connection stability.
Adjusted ANT connection parameters to improve sensor acquisition times.
Fixed an issue that could prevent doing a reset with the button combo on powerup.
Fixed a potential crash when using a paired inReach.
