    Description

      In order to catch unclean shutdown with MongoDB 4.0 and startup with MongoDB 3.6, which could lead to data loss if 3.6 starts updating data with the wrong logging configuration, bump the WiredTiger log file format. Then starting MongoDB 3.6 will fail because the last log file will be a version that is unsupported by WiredTiger.

      This behavior change will be controlled by a "compatibility" version setting, which implies bumping the WiredTiger version.
