Key: = Supported = Deprecated = Not Supported

Java Version |  |
--- | --- | ---
Oracle JDK | 1.7 1.6 1.5 | For the OracleJDK, you can download the Java SE Development Kit (JDK) from the Oracle website. For the OpenJDK, download and install instructions for Linux flavours are at http://openjdk.java.net/install/. Once the JDK is installed, you will need to set the `JAVA_HOME` environment variable, pointing to the root directory of the JDK. See Installing Stash on Windows or Installing Stash on Linux and Mac for details. As of Stash 2.4, support for Java 6 is now deprecated. Stash 3.0+ will require Java 7. If you are using Java 6, Stash requires at least 1.6.0_4 (See STASH-3708).
OpenJDK | 1.7 1.6 1.5
Operating Systems |  |
Apple Mac OS X | (evaluation only) | Stash is a pure Java application and should run on any platform, provided all the JDK requirements are satisfied. In production environments Stash should be run from a dedicated user account. Although Stash can be run in virtualised environments, Atlassian is not yet able to provide technical support for performance-related problems in a virtualised environment. If you do chose to run Stash in a virtual machine, please ensure that you choose a VM with good IO throughput.
Linux |
Microsoft Windows | (Not supported for 500+ Enterprise tiers)
Databases |  |
HSQLDB | (bundled; for evaluation only) | Please see connecting Stash to an external database. MySQL 5.6.x: Note that Stash does not support MySQL 5.6.x, because of bugs in its query optimizer (#68424, #69005). See Connecting Stash to MySQL for more information.
Microsoft SQL Server / Microsoft SQL Server Express | 2005 2008 2008 R2 2012
MySQL | 5.1.x 5.5.x 5.6.x

DVCS Clients |  |
Git - server side | 1.7.6+, 1.8.0 - 1.8.4.2 1.8.4.3+ Cygwin | The version of Git installed on machines that interact with Stash must be compatible with the version of Git installed for use by the Stash server. Git 1.7.1 is not supported. 1.8.4.3+ and higher are not supported due to a critical bug in how symbolic refs are handled. Cygwin: Cygwin Git is not supported for use on Windows servers, regardless of version.

### Hardware requirements

See Scaling Stash regarding the hardware requirements for your Stash installation.

Notes:

Deploying multiple Atlassian applications in a single Tomcat container is not supported. We do not test this configuration and upgrading any of the applications (even for point releases) is likely to break it.

Finally, we recommend not deploying any other applications to the same Tomcat container that runs Stash, especially if these other applications have large memory requirements or require additional libraries in Tomcat's `lib` subdirectory.
