Sam Tuke Nov 9 2020 Share

Welcome to the first-ever Lightmeter Control Center Release Candidate — 1.0.0-RC1. This release provides an opportunity to test the latest changes before the final release of 1.0.0, scheduled for this week.

Changes for testing

  • Introduction of recommendations for problems identified by Local Insights
  • Links to articles in the new Lightmeter Knowledgebase
  • Internationalisation (translation) string handling:
    • New gettext engine adopted
    • Settings page gains newly translatable strings
  • Refactoring of CLI logging, local IP setting storage
  • Postfix parser package migrated to core (no longer an independent package)

The full list of merge requests and commits is on GitLab.

How to test

The best way to test this Release Candidate is to use it as you normally use Control Center, in a non-critical environment. Known issues with this release are documented in the README.


Upgrading to an RC release is the same as for any other Control Center release.

Downgrading is also supported, but because downgrading depends upon features which may not yet be stable, successful downgrading should not be relied upon.

Testing specific features

Features which are user-facing can be easily tested using the Web-UI — see the associated GitLab issues for the expected behaviour and screenshots (sometimes) of how they are intended to look.

Where back-end changes affect a particular component (such as Internationalisation, parsing, etc.), deliberately using functionality which depends on those components provides good opportunities to test for regressions.

Reporting issues

Any found issues should be reported to GitLab, clearly stating the version number of the copy of Control Center that you’re using (e.g. 1.0.0-RC1).
