 ### Added
 
 - Added support for Keeper registry v1.2 in keeper jobs
-- Added disk rotating logs. Chainlink will now always log to disk at debug level. The default output directory for debug logs is Chainlink's root directory (ROOT_DIR) but can be configured by setting LOG_FILE_DIR. This makes it easier for node operators to report useful debugging information to Chainlink's team, since all the debug logs are conveniently located in one directory. Regular logging to STDOUT still works as before and respects the LOG_LEVEL env var. If you want to log in disk at a particular level, you can pipe STDOUT to disk. This automatic debug-logs-to-disk feature is enabled by default, and will remain enabled as long as the `LOG_FILE_MAX_SIZE` ENV var is set to a value greater than zero. The amount of disk space required for this feature to work can be calculated with the following formula: `LOG_FILE_MAX_SIZE` \* (`LOG_FILE_MAX_BACKUPS` + 1). If your disk doesn't have enough disk space, the logging will pause and the application will log Errors until space is available again. New environment variables related to this feature:

If your disk doesn't have enough disk space, the logging will pause and the application will log Errors until space is available again. New environment variables related to this feature:
   - `LOG_FILE_MAX_SIZE` (default: 5120mb) - this env var allows you to override the log file's max size (in megabytes) before file rotation.
   - `LOG_FILE_MAX_AGE` (default: 0) - if `LOG_FILE_MAX_SIZE` is set, this env var allows you to override the log file's max age (in days) before file rotation. Keeping this config with the default value means not to remove old log files.
   - `LOG_FILE_MAX_BACKUPS` (default: 1) - if `LOG_FILE_MAX_SIZE` is set, this env var allows you to override the max amount of old log files to retain. Keeping this config with the default value means to retain 1 old log file at most (though `LOG_FILE_MAX_AGE` may still cause them to get deleted). If this is set to 0, the node will retain all old log files instead.
