Trio v1.0.2 
This release ships an updated driver for Libre 3/3+, brings in a large round of pump and sensor driver updates, fixes alarms that warned too early, a basal rate that showed the wrong number, and a handful of other small issues.
Important
Using a FreeStyle Libre 3 or 3+? You must pair your sensor again after updating.
Trio has switched to an updated Libre driver. It cannot carry your old pairing over, so your sensor will stop sending readings until you re-pair it.
You do not need a new sensor. Keep the one you are wearing. Open Settings → CGM → FreeStyle Libre 3 / 3+, tap Pair New Sensor, and scan the sensor with your phone, exactly like you did the very first time.
Do this as soon as you update. Until you do, Trio has no glucose data and cannot loop.
What's Changed At A Glance
- Not-looping alerts warn you sooner – Trio now nudges you at 20, 40, 60, 80 and 100 minutes, and sounds a critical alarm at 120. Before, you got one critical alarm at 20 minutes and nothing else
- New alarm sound defaults for new installs – critical alarms make a sound, the quieter two types stay silent. If you already have Trio, your own alarm settings are untouched
- Updated driver for Libre 3 / 3+ – more reliable pairing, and a nearby Libre sensor can no longer be paired by mistake. Re-pairing is required, see above
- The basal rate on the Home chart is correct again – it no longer shows a temp basal that was already cancelled, and it tells you when delivery is suspended
- Omnipod pairing in a household with several pods – Trio now only counts pods that are actually ready to pair, so you no longer get a "too many pods found" error
- Medtrum patch fixes – no more crash when a patch reports a halted delivery, and Trio stops you priming before the patch is filled
- Eversense fixes – readings no longer stop unexpectedly, the sensor reconnects after you restart Trio, and more useful data is sent to Eversense DMS
- AccuChek and Eversense show warm-up and expiry – you can see on the Home screen when a sensor is warming up and when it runs out
- Calibrations now show as fingersticks – a calibration you enter is saved as a manual reading with the red drop on the chart, not as a sensor reading
- Dexcom sensor states can go to Nightscout – an off-by-default switch posts a note like "CGM: sensorFailed" when a G6 or G7 reading has no usable glucose
FreeStyle Libre 3 / 3+
Trio's Libre support moved to a new driver, RoundWhiteDiscKit, together with the current version of LibreLoop (#1609).
You must pair your sensor again after updating – see the note at the top. Nothing else about Libre changes for you.
What the new driver brings:
- Pairing is more reliable. It uses a proper app credential, which Trio checks before it is used.
- The right sensor gets paired. Trio now matches the sensor from your NFC scan by its Bluetooth address, so another Libre-family sensor nearby – a Lingo, for example – can no longer win the scan.
- More information when something goes wrong. Settings → Debug Info now shows your sensor's security version and region.
Libre 3 / 3+ support is still marked (Beta) in Trio. It has been tested on a U.S. and EU Libre 3 Plus.
Alarms
- Not-looping alerts now escalate (#1552). Trio used to go straight to one critical alarm at 20 minutes. Now you get a gentler nudge at 20, 40, 60, 80 and 100 minutes, and a critical alarm at 120 minutes. All six are handed to iOS up front, so the warnings keep coming even if iOS puts Trio to sleep. Any successful loop clears them.
- New sound defaults, for new installs only. On a fresh install, Critical alarms play a sound and Time-Sensitive and Normal alarms are silent. If you already have Trio installed, your alarm settings are left exactly as you set them.
Pumps
Omnipod
- Pairing in a house with more than one pod user. Trio now counts only pods that are actually candidates for pairing, so the "too many pods found" error is gone.
- Keep-alive stays out of the background. The "When Open" keep-alive timer no longer runs while Trio is in the background, even if your CGM wakes the app up.
- Silence Pod end time. Picking a time that has already passed no longer hangs the screen.
- Known pods reconnect more simply, with one automatic retry if the pod drops the link. Pod pairing and pod end are now recorded as pump events.
Medtrum
- Priming is blocked until the patch is filled, and the priming screen now shows the reservoir level.
- Trio will not connect to the wrong base, and patch states are checked properly rather than guessed at.
Dana
- Temp basal rates are rounded to two decimal places, and the pump keeps a heartbeat during Continuous mode.
Sensors
Eversense
A large driver update (#1593):
- Readings no longer stop unexpectedly, and crashes during state changes are fixed.
- Your transmitter reconnects after you restart Trio, instead of needing to be set up again.
- Uploads no longer stall when Trio is in the background, and E3 alarms are fixed.
- The 365 handshake retries if it fails, and the vibration toggle silences the transmitter properly.
- More is sent to Eversense DMS to help their support team: app information, transmitter battery history and glucose logs.
AccuChek SmartGuide
- Trio warns you if your sensor model is not supported.
- Calibration screens were tidied up.
Both AccuChek and Eversense
- Warm-up and expiry now show on the Home screen (#1592), the same way they do for other sensors.
- Calibrations are stored as fingersticks (#1472). A reading you enter yourself is now saved as a manual glucose entry – the red drop on the chart – rather than being mixed in with sensor readings.
Dexcom
- Sensor states can be sent to Nightscout (#1420). A new switch under Nightscout → Upload, off by default, posts a note such as "CGM: sensorFailed" whenever a G6 or G7 reading arrives without usable glucose. Each state is noted once per occurrence.
In the App
- The basal rate on the Home chart is right again (#1556). It no longer shows a temp basal that has already been cancelled – for example after switching to Basal Testing. It also shows your scheduled rate before the pump has any history, marks a manual temp basal as manual, and says when delivery is suspended.
- Override presets no longer crash the Adjustments screen (#1571). Presets saved by older builds with missing or unusual values were enough to bring the screen down.
- The bolus keyboard stops covering the field you are typing in (#1434), along with some related scrolling problems in the Treatments view.
- Settings hints are no longer cut off in longer translations (#1408), and the two Home grid toggles no longer touch each other at small text sizes (#1575).
- Updated translations across Trio and its drivers, from our Crowdin and Lokalise contributors.
Upgrade Notes
From 1.0.1 or 1.0
If you use a Libre 3 / 3+, pair your sensor again straight after updating – see the note at the top of these release notes. That is the only thing you have to do.
Everything else carries over: no settings change, no migration, no onboarding. If you are a new Trio user, check your alarm sound settings, as the defaults for new installs changed.
From 0.8.4
Read the 1.0 release notes – everything in their upgrade section still applies to you, including checking your alarm settings and your App Diagnostics preference. Your configuration, therapy settings, history and device connections carry over; there is no onboarding wizard and no settings reset.
From 0.2.x
Read the 0.7.0 upgrade notes and the Migration Guide on TrioDocs first, then the 1.0 notes.
From 1.0.1.x (dev)
You are already running this code. No action needed beyond switching to main.
A Note From The Trio Team
Trio has not been reviewed by the FDA or any other regulatory body. Nothing in these notes is medical advice; if a change here affects how you manage your diabetes, talk it through with your care team.
