-title: "Apache Drill 1.8.0 Release Notes"
-parent: "Release Notes"
----
-
-**Release date:** August 30, 2016
-
-Today, we're happy to announce the availability of Drill 1.8.0. You can download it [here](https://drill.apache.org/download/).
-
-## New Features
-This release of Drill provides the following new features:
-
-- Metadata cache pruning
-- IF EXISTS parameter with the DROP TABLE and DROP VIEW commands
-- DESCRIBE SCHEMA command
-- Multi-byte delimiter support
-- New parameters for filter selectivity estimates
-
-## Configuration and Launch Script Changes
-This release of Drill also includes the following changes to the configuration and launch scripts:
-
-- The `$DRILL_HOME/conf/drill-env.sh` file has been simplified. Default Drill settings have moved out of this file and now reside in `$DRILL_HOME/bin/drill-config.sh`. The `drill-env.sh` file now ships with descriptions of the options that you can set. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. ([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))
-
-Changes to the Drill launch scripts provide a new option that simplifies the Drill upgrade for Drill 1.8 and later. The new scripts support a “site directory” that holds site-specific files separate from the Drill product directory. The site directory is a simple extension of the config directory in previous Drill releases. You can add a “jars” subdirectory to the config directory for your custom jars instead of storing them in $DRILL_HOME. You can even add native libraries in the new “lib” directory and Drill automatically loads them.
-
-Example:
-
- /my/conf/dir
- |- drill-override.conf
- |- drill-env.sh
- |- jars
- |- myudf.jar
- |- lib
- |- mysecurity.so
-
-To use the site directory:
-
- drillbit.sh —site /my/conf/dir start
-
-Note that `--config` still works as well.
-
-You can set an environment variable for the directory:
-
- export DRILL_CONF_DIR=/my/conf/dir
- drillbit.sh start
-
-The site directory works with `drillbit.sh` and the various Drill client scripts.
-
-To upgrade Drill using the new site directory, just delete the old Drill product directory and expand the Drill archive to create a new one. There is no need to back up and merge files each time you upgrade because the site files are not affected by an upgrade. Using the site directory, you can have different site directories for different Drill sessions: one for development, another for test, and so on. You can use the site directory to run multiple Drill clusters from as single Drill installation by creating a site directory for each Drill cluster and then configuring Drill.

+title: "Apache Drill 1.8.0 Release Notes"
+parent: "Release Notes"
+---
+
+**Release date:** August 30, 2016
+
+Today, we're happy to announce the availability of Drill 1.8.0. You can download it [here](https://drill.apache.org/download/).
+
+## New Features
+This release of Drill provides the following new features:
+
+- Metadata cache pruning
+- IF EXISTS parameter with the DROP TABLE and DROP VIEW commands
+- DESCRIBE SCHEMA command
+- Multi-byte delimiter support
+- New parameters for filter selectivity estimates
+
+## Configuration and Launch Script Changes
+This release of Drill also includes the following changes to the configuration and launch scripts:
+
+- The `$DRILL_HOME/conf/drill-env.sh` file has been simplified. Default Drill settings have moved out of this file and now reside in `$DRILL_HOME/bin/drill-config.sh`. The `drill-env.sh` file now ships with descriptions of the options that you can set. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. ([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))
+
+Changes to the Drill launch scripts provide a new option that simplifies the Drill upgrade for Drill 1.8 and later. The new scripts support a “site directory” that holds site-specific files separate from the Drill product directory. The site directory is a simple extension of the config directory in previous Drill releases. You can add a “jars” subdirectory to the config directory for your custom jars instead of storing them in $DRILL_HOME. You can even add native libraries in the new “lib” directory and Drill automatically loads them.
+
+Example:
+
+ /my/conf/dir
+ |- drill-override.conf
+ |- drill-env.sh
+ |- jars
+ |- myudf.jar
+ |- lib
+ |- mysecurity.so
+
+To use the site directory:
+
+ drillbit.sh —site /my/conf/dir start
+
+Note that `--config` still works as well.
+
+You can set an environment variable for the directory:
+
+ export DRILL_CONF_DIR=/my/conf/dir
+ drillbit.sh start
+
+The site directory works with `drillbit.sh` and the various Drill client scripts.
+
+To upgrade Drill using the new site directory, just delete the old Drill product directory and expand the Drill archive to create a new one. There is no need to back up and merge files each time you upgrade because the site files are not affected by an upgrade. Using the site directory, you can have different site directories for different Drill sessions: one for development, another for test, and so on. You can use the site directory to run multiple Drill clusters from as single Drill installation by creating a site directory for each Drill cluster and then configuring Drill.
+
+The following sections list additional bug fixes and improvements:
