Configuration Changes

In this release, the schema version has changed from 10 to 12.

• Parameter dns.querylog_interval, which in schema versions 11 and earlier used to be an integer number of days, is now a string with a human-readable duration:

  # BEFORE:
  'dns':
    # …
    'querylog_interval': 90
  
  # AFTER:
  'dns':
    # …
    'querylog_interval': '2160h'
  

  To rollback this change, convert the parameter back into days and change the schema_version back to 11.

• Parameter rlimit_nofile, which in schema versions 10 and earlier used to be on the top level, is now moved to the new os object:

  # BEFORE:
  'rlimit_nofile': 42
  
  # AFTER:
  'os':
    'group': ''
    'rlimit_nofile': 42
    'user': ''
  

  To rollback this change, move the parameter on the top level and change the schema_version back to 10.
