Emoncms v9.9.0+ release notes

The emoncms v9.9.0+ release is an intermediate release merging the active master branch of emoncms into stable in particular for access to the new python based service runner for the RPi3 B+ image build.

New developments such as the new inputs and feeds interface are still in beta and are available via an opt-in switch on the user account page. Work is ongoing on these features and therefore bugs are still expected. The new interfaces can be disabled via the same opt-in toggle switch. There will be a separate full release of the new inputs and feeds interface after further work is completed.

  • Unsupported red process list notices in input view: This is caused by browser caching of old javascript and can be fixed by clearing browser cache. Emoncms should with update 9.9.1 do this automatically but its not universally supported across browsers.

  • Negative value in stacked bar chart, clear browser cache as above.
