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

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 is a patched version (fixed Browser Build) without changes to the features of Loop 3.4.x
    • Loop 3.5.0 is the current development version

Remove Apps with Shared App Group

The storage of data with Loop 3 is not backward compatible. In other words, if you attempt to build Loop 2.2.x (or FreeAPS) on a phone which has been upgraded to Loop 3, you will not be able to run that app. You can successfully build the app, which will overwrite Loop 3 on the phone, but the app will crash and you will not be able to Loop.

At this point, you can restore your Loop 3 build on your phone and continue using Loop 3 or you delete all apps on your phone with a shared app group. This list includes Loop, FreeAPS, FreeAPS X, iAPS, xDrip4iOS, Glucose-Direct, and the g5 Transmitter Reset app.

If you tried to delete "all" the apps and still have something causing an issue; you can follow the directions to Review Provisioning Profiles and then delete the profiles for all the apps by using the - sign.

You do not need to delete LoopFollow, so if you use LoopFollow - do not delete that provisioning profile.
