- Default Drill settings now reside in `$DRILL_HOME/bin/drill-config.sh`. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. The file includes descriptions of the options that you can set. ([DRILL-4581](https://issues.apache.org/jira/browse/DRILL-4581))
- Due to issues at high concurrency, the native Linux epoll transport is now disabled by default. ([DRILL-4623](https://issues.apache.org/jira/browse/DRILL-4623))
-If you upgrade to Drill 1.8, you must merge your custom settings with the latest settings in the `drill-override.conf` and `drill-env.sh` file that ships with Drill. As of Drill 1.8, all Drill defaults reside in the Drill scripts. The `drill-env.sh` script contains only your customizations. When you merge your existing `drill-env.sh` file with the 1.8 version of the file, you can remove all of the settings in your file except for those you created yourself. Consult the original `drill-env.sh` file from the prior Drill release to determine which settings you can remove.
