Breaking Changes

Pushing Large and Visible Changes

• don't break widely used workflows
• provide option to opt out if new behaviour is enabled by default
• don't complicate things and expect users to read the wiki
• most of the user problems issues go unreported

Extensive Testing Before Pushing to Production

• don't slip in the changes at the last minute
• never assume your workflow to be the workflow
• development environment is not the same as the production/installation
