Happy holidays from the #WeAreNotWaiting Rogue Cowboys!

To end the year with a bang, here’s a new release of Nightscout! This release ended up being a bit bigger than expected, with a total of 12186 lines of code changes from 26 participants. In addition to the list including many first time contributors, we have three absolute heroes for this release, with Jeremy Cunningham volunteering to upgrade the D3 library we use for the graph rendering to the latest version, Petr Ondrusek’s new V3 API and Caleb Hornbeck’s rewrite of the Alexa and Google Home support.

If you’re wondering if you should update to the latest release, read up! The graph rendering and other parts of the code were optimised significantly, so Nightscout web page now loads in under 1 second on fast browsers on fast a fast connection. This also makes the site a lot more usable on old devices - we tested the site on an iPad mini 1 running iOS 9 and it’s actually now usable (even if slow) and scrolling back the history is now butter smooth on newer devices. If you like speed, go update.

The release changes the version number scheme - instead of this being release 0.13.0, the release is now numbered 13.0.0. This change was done so we can comply with the usual way version numbers are used (so 13.0.1 would be a bug fix release after this and 13.1.0 would mean we’ve added new features).

As before, we recommend Heroku for hosting Nightscout. Users on Azure should migrate their site over to Heroku - this is a quite simple process and you won’t lose any data. Instructions how to do this are here: https://bfaloona.github.io/loopdocs/nightscout/azure_migration/

Developers: new V3 API

The new APIv3 generally provides secured and HTTP REST compliant interface for Nightscout's data exchange. It treats collections in a generic way, provides improved deduplication mechanism and brings possibility to incrementally track data changes (including its own lightweight Socket.IO channel for it).

The V3 API should be considered to be in beta during the release 13 series and we’ll be extremely happy for any feedback on the new API.

To get started, the API documentation is at https://github.com/nightscout/cgm-remote-monitor/blob/dev/lib/api3/doc/
