3.6.0 Highlights

• Add Automatic Certificate Generation and Renewal
• Implement updates to minimize Dexcom G7 outages that were reported over the last few months, possibly related to iOS 18 changes
• Modify the bolus after meals button to say Save Carbs & Deliver
• Update Omnipod Eros and DASH repositories: some bug fixes, some improved responses
• Fix a few bugs
  • Fixed: Stale value of the total bolus in the Bolus Progress Display in HUD - UI Bug only
  • Fixed: Glucose change graph 'predicted' effects are inconsistent at different times or between orientations
  • Fixed: Dexcom G7 calibration flags were not decoded correctly
  • Fixed: Dexcom G7 rare but significant date offset for glucose data
    • If the backfillFinished message was not detected and a stale backFill message was applied to a new sensor, the date for that glucose reading would be in error
  • Fixed: The Algorithm Experiments screen could show stale selections - UI Bug only
  • Not Fixed: The Basal Rate section of the Therapy Settings screen does not update until you exit the screen and then return (this will be addressed in a future update) - UI Bug only, and only seen on some phone hardware (like SE phones) with iOS 18

3.6.0 Details

Add Automatic Certificate Generation and Renewal

Automatic certificate generation and renewal requires a Variable be added to your organization or your repository. Please see these instructions: Add Variable

Maintenance Updates

These maintenance changes do not affect the functioning of the Loop app but do enable continued build with current iOS, Xcode and macOS versions, as well as continued operation of the GitHub Actions (Browser Build) capability.

• LoopWorkspace PR 234: Modify GitHub action files to enable automatic renewal of certificates when they expire or are revoked
• LoopWorkspace PR 241, Loop PR 2303: Modify the way the Loop app is versioned - it is now updated in the LoopWorkspace repository instead of the Loop repository - this simplifies version releases
• LoopWorkspace PR 243: Update GitHub action files to use fastlane 2.227.1 and Xcode 16.3
• LoopWorkspace PR 248: Enable GitHub build to continue working after the keepalive-workflow repository was disabled by GitHub

Feature Updates

These are changes in response to feature requests (Loop Issues) that were implemented in the noted submodule. The LoopWorkspace respository was subsequently updated to include the feature.

Loop Issue	Submodule Updated	PR in Submodule	Request	Modification

OmniBLE and OmniKit Updates

Updates were made to the Omnipod pump submodules: OmniBLE and OmniKit. Unless otherwise noted, the following functional updates were made to both submodules with the PR numbers included in parentheses:

• Miscellaneous Omnipod code improvements & cleanup (PR 135, 44)
• Unacknowledged command handling fixes and PodCommsSession improvements (PR 136, 45)
• DASH (OmniBLE only): Don't fail on ack comms error if validated response has been received (PR 137)

Loop v3.4.4

Loop v3.4.4 restored the TestFlight expiration date for Browser Build - it was released twice with the same build number. Just make sure your build (for both Browser Build and Mac Build) are later than 12 October 2024.

• The first release on 9 October 2024 inadvertently removed all the improvements from v3.4.3, but did fix the TestFlight expiration date

• The second release on 12 October 2024 restored the improvements from v3.4.3

• Link to release notes for Loop 3.4.4

Loop v3.4.3

Loop v3.4.3 was released on 6 October 2024.

A few days later, it was discovered that the TestFlight expiration date was no longer available for Browser Build (due to a change in 3.4.2). This was quickly remedied with the Loop 3.4.4 release.

This was a minor update to the Loop code with a few bug fixes and some capability extensions.

Please use the main branch

Some people have become complacent about using the dev branch to get the latest updates. This is a good time to switch to the main branch.

New revision will be landing in the dev branch soon. Don't be surprised - stick with main until the changes have been tested.

The Browser Build method was updated to use Fastlane version 2.223.1. This change (208) fixes a build error reported by several folks across the Open Source app community. This was also added to LoopWorkspace dev branch (207).

Loop v3.4.2

Loop v3.4.2 was released on 5 October 2024.

This was a patch that fixed errors with the expiration date for the Mac-Xcode build method for Xcode 16. No other changes were made. Unfortunately, the method used to fix expiration date for Mac Xcode 16 builders removed the expiration date for Browser Builders. The expiration date for Browser Builders was restored with version 3.4.4.

Pete's announcment:

Loop 3.2 Is released! This contains some very important bug fixes for everyone. If you are running latest dev, you do not need to update, but everyone else running older 3.x versions of Loop should consider upgrading as soon as you can.

https://github.com/LoopKit/Loop/releases/tag/v3.2.0

Bug Fixes (Please update ASAP):

• Omnipod bolus tracking issue fixed: link
• Medtronic temp basal tracking issue fixed: link
• Crashes caused by large updates from Apple Health fixed
• Automatic refresh timers for Omnipod (both Dash and Eros) have been removed, to reduce load on pods and reduce frequency of failed pods.

Updates and new Features:

• Missed Meal Notifications. If you want, Loop will detect situations where it looks like you may have consumed carbs but did not enter them into Loop, and will notify you with an easy option to enter the amount, and the time of eating already estimated for you. Find this option in the Alert Management section of Loop settings.
• Tidepool Service added. This lets you upload your diabetes data from Loop to Tidepool! It is in early stages, so there may be issues. Please report any issues you have with this integration on DIY Loop forums, like Zulip, GitHub, or the Looped group.
• Translations! Loop now has very good coverage for several languages, including German, Spanish, Italian, French, Danish, Polish, Dutch, Norwegian, Russian, Turkish, and Romanian!
  • Warning - a few items got overwritten by Spanish - if you can't figure it out, try Google translate
• A new safeguard restricts automatic dosing to keep your IOB below a limit of 2 times your max bolus. Manual dosing can still be delivered to put your IOB above this amount. link
• Add missing X-Large watch complications. link
• “Deactivate Pod” button on some screens changed to not be so alarming, as it doesn’t actually deactivate the pod, but takes you to a screen where you can, and has an option to cancel: link

Loop v3.0.0

After several years of development and a lot of testing, Loop 3 is here!

Loop v3.0.0 was released on January 14, 2023.

Use Script not Zip

If you follow that link above, there is an Assets section with a zip link

• Do not try to build from the zip link
• For Browser Build, refer to: GitHub Overview
• For Build with Mac refer to:
  • Updating
  • Build the Loop App

Branch Name Change

The branch name associated with the latest Loop release is main.

• All new Git repositories on GitHub will be named main instead of master starting October 1, 2020
• GitHub provides tools to assist in modifying existing repositories to use main

Loop Version Numbering

With the release of Loop 3, there is a new pattern for identifying the releases as distinct from the development work.

Each release uses 3 numbers: Major.Minor.Patch

• Major is reserved for a significant change in the code, such as occurred going from Loop 2.2.9 to Loop 3.0.0
• Minor is used when the development branch is released for general use
• Patch typically indicates a modification for a quick bug-fix or to support external events like an Xcode or iOS version update with no feature changes in Loop

To prevent confusion between versions used for development and versions used for release (main branch), the Minor values are even for released code. The Minor value for the development branch (dev) is incremented as part of the release process and is always odd.

For example:

• Loop 3.0.0 was the first released version of Loop 3
  • Loop 3.1.0 was the development version before Loop 3.2.0 was released
• Loop 3.2.0 was the next released version
  • Loop 3.2.1, 3.2.2 and 3.2.3 are patches to Loop 3.2.0 without changes to the features of Loop 3.2.x
  • Loop 3.3.0 was the development version before Loop 3.4.0 was released
• Loop 3.4.0 was the next released version
  • Loop 3.4.1, Loop 3.4.2, Loop 3.4.3 and Loop 3.4.4 are patched versions without major changes to the features of Loop 3.4
  • Loop 3.5.0 was the development version before Loop 3.6.0 was released
• Loop 3.6.0 is the current released version
  • Loop 3.7.0 is the current development version

Remove Apps with Shared App Group

There are a number of Open Source apps which use the Loop App Group to share data.

One consequence of this is that if you delete one of those apps, there may be saved information on the phone that is not discarded. Normally this is not a problem, but sometimes you really want to wipe out all the stored information.

If you are in a situation where you want to completely wipe all data from your phone for any of these apps which use the Loop App Group, you might need to delete all of them:

• Active Apps: Loop, xDrip4iOS, Glucose-Direct, iAPS
• Old Apps that might be hanging around: FreeAPS, FreeAPS X and the G5 Transmitter Reset app

These apps either have their own App Group or do not use an App Group and do not need to be deleted:

• LoopFollow, LoopCaregiver, Trio
