Trio v0.6.0

Trio v0.6.0 Public Beta Update

This update introduces APNS feedback for Remote Commands — a major enhancement enabling secure and reliable feedback push notifications between LoopFollow and Trio.

It also formally includes all additions to Trio dev between 0.5.1.0 and this release. If you have been running the latest version of dev, v0.5.1.28, you will have had access to all these changes except for the breaking change to remote command capabilities and the automated browser building schedule update.

Additionally, several key bug fixes and refinements improve Live Activity behavior, Watch performance, DanaKit integration, and CGM data stability.

Trio v0.2.7

Trio Hotfix v0.2.7

This maintenance release restores Add Identifiers functionality and updates fastlane tooling.

Important

This release brings back Browser Build abilities

What Was Changed?

• Fastlane:
  Switched to a custom fastlane build based on version 2.228.0 with PR #29596 applied.
  This resolves a recent Apple-side issue that prevented the Add Identifiers action from succeeding.

  • The Gemfile now references a specific SHA from the loopandlearn/wip_2.228.0_pr29596 fork.
  • bundle update fastlane applied; updated Gemfile.lock committed.
  • The fastlane/Fastfile now sets the platform explicitly in configure_bundle_id.

• Build Reliability:
  Add Identifiers step now successfully executes both when identifiers are already present and after a partial deletion, validating the fix across different scenarios.

Thank you to everyone who contributed! @marionbarker @dnzxy

Trio v0.2.6

Trio v0.2.6

This maintenance release improves CI robustness and updates project metadata.

What Was Changed?

• GitHub Actions:
  build_trio.yml now checks for alive-main and alive-dev branches independently and creates only the missing ones. This avoids relying on a single combined flag and ensures cleaner setup.

• CODEOWNERS:
  Removed JS-specific ownership and added @marv-out to global owners.

Thank you to everyone who contributed! @bjornoleh @marionbarker @dnzxy

Trio v0.5.0

Trio v0.5.0 – Public Beta

Soon… is NOW.

This public beta release is the culmination of thousands of hours of work by dozens of contributors since late 2023. Trio has been rebuilt from the ground up for clarity, reliability, and usability—with a new look, powerful new features, and a strong focus on user experience and safety.

This isn’t just another app update. This is the next chapter of open source AID.

What’s New

• Brand New Interface
  A completely redesigned UI across the app and watchOS—clean, modern, and easier to use.

• All-New Onboarding
  Step-by-step setup for new and returning users with smart defaults and safety checks.

• Rewritten Backend & Data Storage
  Entire app logic and data storage rewritten for speed, stability, and future flexibility.

• Remote Commands & iOS Shortcuts
  Trigger actions like carb entry, bolus, overrides or temporary targets remotely [1] or through automation.

• Smarter Settings
  Helpful hints, guidance sheets, and a built-in search function—just like iOS Settings. The all-new Trio Settings.

• New Bolus Calculator
  More accurate, simple dosing with clearer breakdowns and improved safety logic.

• Reworked Statistics
  All in-app statistics and graphs have been overhauled and extended.

• Live Activity Widget
  Real-time loop data with optional chart—configurable and tailored to your preferences.

• Live Data on Watch
  Highly customizable “contact widgets” for glucose, IOB, COB, and more, always visible.

• All-New Integrations
  Nightscout, Tidepool, and Apple Health connections have been rebuilt from scratch—faster and more stable.

• Safety Improvements
  Dynamic ISF guarding (7-day required data), safer edge-case behavior, and improved support for high-insulin-resistance setups.

• Updated Language & Translations
  Clear, friendly, and easy-to-understand. Fully localized with ongoing help from our Crowdin contributors (translators still welcome).

[1] requires Loop Follow v2.4.0

Important Notes for Public Beta Testers

Important

• All users must complete the Onboarding Wizard after upgrading.
• If migrating from a previous 0.2.x build, 24 hr treatment data and therapy settings will be preserved.
• Your pump and CGM connections will be brought over automatically.
• Algorithm settings, dynamic ISF and some integrations (like Nightscout) will reset.

This public beta is intended for experienced users and long-time Trio 0.2.x users, not beginners.
→ Visit TrioDocs for instructions and help on how to update and build.
→ Feedback is welcome via GitHub Issues or the community Discord

Note

A Note on Compatibility
Upgrading to Trio v0.5.0 from 0.2.x is smooth and straightforward. The new Onboarding Wizard will guide you step by step.

Be Aware:

• Once you have upgraded to v0.5.0, going back to 0.2.x is not supported.
• If you choose to downgrade, you will need to set everything up again from scratch.

We have designed this release to be a stable and long-term foundation—so when you are ready, you can upgrade with confidence.

Thanks to all Contributors

A heartfelt thank you to every contributor, tester, translator, and supporter who made this release possible. Your time, care, and belief in open source AID is what powers Trio—not just the app, but the community behind it. This beta is yours.

Trio v0.2.5

Trio v0.2.5

This Hotfix Release preserves build ability for browser builders after a tooling that was used to keep repositories from going stale was taken down by GitHub for Terms of Service violations.

Background

The gautamkrishnar/keepalive-workflow has been taken down by GitHub. We now know this is a permanent change, as the action violates GitHub's terms of service. This PR makes a minimal change to the current build_trio.yml which renables building with GitHub actions.

What Was Changed?

• Comment out the section that is not available and insert an echo for the log file.
• A permanent fix will need to be implemented later, this is a bandaid to prevent build workflows from failing.

Testing

This was testing by team member @bjornoleh in his Trio fork here.

Thank you to everyone who contributed and for the very quick coordination across iOS OS-AID apps for this hotfix release!
@bjornoleh @marionbarker @dnzxy

Trio v0.2.4

Trio v0.2.4

This release includes critical fixes for pump managers, improvements to G7 sensors (solving some cutouts and connection loss), and updates to browser build tooling for upcoming platform requirements (the infamous "April 24 deadline").

Pump Manager Updates

• OmniPod communication accuracy
  Fixed an edge case where podSuspended was misreported and added tryToValidateComms() to confirm pod state before reporting. Integrates OmniBLE PR141 and OmniKit PR49.
  (#469, via @marionbarker, @itsmojo)

• MinimedKit basal‑rate rounding
  Ensures temporary basal rates are rounded to valid increments before enactment, preventing duplicate entries and invalid‑rate errors.
  (#486, via @MikePlante1)

G7 SensorKit Enhancements

• Smarter session‑end detection
  Adds improved detection for end-of-session states using connectivity and algorithm state decoding.
  • This improves performance in which G7 sensor readings have not been appearing in the main Trio screen for use in looping. There can still be issues, but this reduces the number.
  • The underlying PR (to G7SensorKit) fixes an issue where an AID misinterpreted an active Dexcom G7 sensor as ended, causing it to enter a prolonged scanning state. It improves this "session end detection", reducing false positives. Users confirmed it reduces missed readings and improves stability, though not a complete fix in all cases.
    (#483, via @marionbarker, @ps2)

Browser Build Tooling

• macOS 15 & Xcode 16.2 migration
  Upgrades workflows‘ macOS and Xcode versions in preparation for App Store policy changes.
  (#473, via @bjornoleh)

• Fastlane & Xcode consistency
  Bumps Fastlane to 2.227.1 and Xcode to 16.3 to align with LoopKit’s build setup.
  (#482, via @marionbarker)

• Customization patch support
  Introduces a patches/ directory and templating mechanism for project‑specific modifications during GitHub‑hosted browser builds, simplifying one‑off adjustments.
  (#476, via @marionbarker)

Trio v0.2.3

Trio v0.2.3

This release streamlines certificate management in browser build workflows, rolls in key OmniBLE/OmniKit fixes, and cleans up issue workflows and documentation ahead of upcoming builds.

Browser Build Certificate Automation

• Auto‑renew Distribution Certificates
  • Detects invalid or expired iOS Distribution certificates and provisioning profiles during the browser build process.
  • Automatically creates or renews them as part of the GitHub Actions browser build steps, eliminating the manual annual renewal burden.
    (#453, via @bjornoleh)

OmniBLE & OmniKit Submodule Updates

• Stability & Fault Prevention
  • Merged critical fixes from OmniBLE PRs [#135](LoopKit/OmniBLE#135), [#136](LoopKit/OmniBLE#136), [#137](LoopKit/OmniBLE#137), [#138](LoopKit/OmniBLE#138), [#139](LoopKit/OmniBLE#139), [#140](LoopKit/OmniBLE#140) and OmniKit PRs [#44](LoopKit/OmniKit#44), [#45](LoopKit/OmniKit#45), [#46](LoopKit/OmniKit#46), [#47](LoopKit/OmniKit#47), [#48](LoopKit/OmniKit#48) to prevent communication faults and improve overall pump connectivity.
    (#445, via @itsmojo, @marionbarker)

Workflow & Docs Improvements

• Issue Tracking Enhancement

  • Switched from tag‑based to type‑based classification for GitHub issues, clarifying workflows and automations.
    (#461, via @Sjoerd-Bo3)

• Documentation Fix

  • Corrected a broken link in the README to ensure all resources resolve correctly.
    (#442, via @ebouchut)

Setup Note:

To enable browser build’s automatic certificate renewal, add an Action variable:

1. Go to Settings → Secrets and variables → Actions → Variables
2. Click Create new organization variable (or repository‑level if not using an org)
3. Name it ENABLE_NUKE_CERTS with the value true
   This makes the renewal step visible and editable without using secrets.
