|Title||Do not fail on errors in *.mk files anymore - except in interactive mode|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
If a syntax error in main.mk or other *.mk files occurs, Check_MK used to abort any operation. This is nasty when for example a new variable that has been introduced in a new version is not known in an older version of Check_MK and thus after a version downgrade the configuration cannot be activated any more.
The behaviour has now changed so that in case of such an error Check_MK will only abort in interactive mode, i.e. if the standard output is a terminal. That means that WATO will always try to activate Changes. You can force the old behaviour by adding the new option --interactive.
