+* Improvements in the Drill JDBC driver including inclusion of
+[Javadocs]({{site.baseurl}}/api/1.2/jdbc/) and better application dependency compatibility
+* Enhancements to Avro file formats
+ * [Support for complex data types](https://issues.apache.org/jira/browse/DRILL-3565), such as UNION and MAP
+ * [Optimized Avro file processing](https://issues.apache.org/jira/browse/DRILL-3720) (block-wise)
+* Partition pruning improvements
+* A number of new [SQL window functions]({{site.baseurl}}/docs/sql-window-functions)
+ * NTILE
+ * LAG and LEAD
+ * FIRST_VALUE and LAST_VALUE
+* [HTTPS support]({{site.baseurl}}/docs/configuring-web-console-and-rest-api-security/) for Web Console operations

+## Important Unresolved Issues
+
+* The Drill error message about JSON syntax that appears when Drill cannot find the JDBC driver during configuration of the JDBC storage plugin is misleading. To configure the JDBC plugin, you must put the JDBC driver in the `<drill_installation_directory>/jars/3rdparty` directory. [DRILL-3985](https://issues.apache.org/jira/browse/DRILL-3958)
+* The MySQL TEXT type is not supported. The popular classicmodels database uses the TEXT type, and therefore cannot be used as is until this issue is resolved. [DRILL-3956](https://issues.apache.org/jira/browse/DRILL-3956)

+Today, we're happy to announce the availability of Drill 1.12.0. You can download it [here](https://drill.apache.org/download/).
+
+The release provides the following bug fixes and improvements:
+
+## Kafka and OpenTSDB Storage Plugins (DRILL-4779, DRILL-5337)
+You can configure Kafka and OpenTSDB as Drill data sources.
+
+- For Kafka storage plugin information, see the [README](https://github.com/apache/drill/blob/master/contrib/storage-kafka/README.md) file.
+- For OpenTSDB storage plugin information, see the [README](https://github.com/apache/drill/blob/master/contrib/storage-opentsdb/README.md) file. Configure the OpenTSDB storage plugin in the Storage tab of the Drill Web Console, as shown:
+
+ {
+ "storage": {
+ openTSDB: {
+ type: "openTSDB",
+ connection: "http://localhost:10000",
+ enabled: false
+ }
+ }
+ }
+
+## Queue-Based Memory Assignment for Buffering Operators (Throttling) (DRILL-5716)
+Throttling limits the number of concurrent queries that run to prevent queries from failing with out-of-memory errors. When you enable throttling, you configure the number of concurrent queries that can run and the resource requirements for each query. Drill calculates the amount of memory to assign per query per node. See [Throttling]({{site.baseurl}}/docs/throttling/) for more information.
+
+
+
+## Networking Functions
+Drill supports the following networking functions to facilitate network analysis using Drill:
+
+- `inet_aton(<ip>)`: Converts an IPv4 address into an integer
+- `inet_ntoa( <int>)`: Converts an integer IP into dotted decimal notation
+- `in_network( <ip>,<cidr> )`: Returns true if the IP address is in the given CIDR block
+- `address_count( <cidr> )`: Returns the number of IPs in a given CIDR block
+- `broadcast_address( <cidr> )`: Returns the broadcast address for a given CIDR block
+- `netmask(<cidr> )`: Returns the netmask for a given CIDR block
+- `low_address(<cidr>)`: Returns the first address in a given CIDR block
+- `high_address(<cidr>)`: Returns the last address in a given CIDR block
+- `url_encode( <url> )`: Returns a URL encoded string
+- `url_decode( <url> )`: Decodes ``a URL encoded string
+- `is_valid_IP(<ip>)`: Returns true if the IP is a valid IP address
+- `is_private_ip(<ip>)`: Returns true if the IP is a private IPv4 address
+- `is_valid_IPv4(<ip>)`: Returns true if the IP is a valid IPv4 address
+- `is_valid_IPv6(<ip>)`: Returns true if the IP is a valid IPv6 address
+
+## SSL Support
+Drill supports SSL to encrypt data passed between the Drill client and Drillbit. SSL also provides one-way authentication through which the Drill client verifies the identity of the Drillbit. The SASL feature in Drill provides authentication and an option to encrypt data, however the encryption feature is not available when using Plain authentication. If you need to use Plain authentication (certain BI tools only use Plain authentication), you can enable SSL to encrypt data. You can have both SASL and SSL enabled when using Plain authentication only. For any other scenario, using SSL and SASL encryption together is strongly discouraged. The Drill server requires an SSL certificate. The certificate can be self-signed or signed by a CA (Certificate Authority). SSL is not supported for communication between Drillbits.
+
+## Network Encryption Support
+Drill 1.10 provided authentication support through Plain and Kerberos authentication mechanisms to authenticate the Drill client to Drillbit and Drillbit to Drillbit communication channels. Drill 1.11 extends that support to include encryption. Drill uses the Kerberos mechanism over the SASL framework to encrypt the communication channels.
+
+
+## Access to Paths Outside the Current Workspace (DRILL-5964)
+A new parameter, allowAccessOutsideWorkspace, in the dfs storage plugin configuration prevents users from accessing paths outside the root of a workspace. The default value for the parameter is false. Set the parameter to true to allow users access outside of a workspace. If existing storage plugin configurations do not specify the parameter, users cannot access paths outside the configured workspaces.
+
+
+You can find a complete list of JIRAs resolved in the 1.12.0 release [here](https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12341087&styleName=Html&projectId=12313820&Create=Create&atl_token=A5KQ-2QAV-T4JA-FDED%7Cd194b12b906cd370f36d15e8af60a94592b89038%7Clin).

-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.
-

-Today, we're happy to announce the availability of Drill 1.4.0, providing the following bug fixes and improvements.

-## Important Unresolved Issues
-
-* The Drill error message about JSON syntax that appears when Drill cannot find the JDBC driver during configuration of the JDBC storage plugin is misleading. To configure the JDBC plugin, you must put the JDBC driver in the `<drill_installation_directory>/jars/3rdparty` directory. [DRILL-3985](https://issues.apache.org/jira/browse/DRILL-3958)
-* The MySQL TEXT type is not supported. The popular classicmodels database uses the TEXT type, and therefore cannot be used as is until this issue is resolved. [DRILL-3956](https://issues.apache.org/jira/browse/DRILL-3956)

+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:

+---
+
+**Release date:** December 14, 2015
+
+Today, we're happy to announce the availability of Drill 1.4.0, providing the following bug fixes and improvements.
+
+Drill 1.4 fixes an error that occurred when querying a Hive table using the HBaseStorageHandler ([DRILL-3739](https://issues.apache.org/jira/browse/DRILL-3739)). To successfully query a Hive table using the HBaseStorageHandler, you need to configure the Hive storage plugin as described in the [Hive storage plugin documentation]({{site.baseurl}}/docs/hive-storage-plugin/#connect-drill-to-the-hive-remote-metastore).
