How to handle config changes on core update?
Schema updates in different versions of core and contrib which cause changes to the config will cause an issue where your config becomes outdated.

On your local environment, run:

drush updb
drush cex


Then you can commit and push your configuration, and on your target (i.e. production, or stage, etc) environment, run:

drush updb
drush cim


Failure to do so will cause hard-to-diagnose issues in some case. More info and examples at:


Update hooks which modify configuration can lead to unstable sites; figure out how to deal with this.
