Evergreen depends on the following technologies Perl, C, JavaScript, XML, XPath, XSLT, XMPP, OpenSRF, Apache, mod_perl, and PostgreSQL.
The latest stable release of a supported Linux distribution is recommended for an Evergreen installation. For Ubuntu, please use a 64-bit LTS (long term support) Server release.
Currently the latest release from the Evergreen 3.12 series is recommended for new installations and stable releases are suggested for production systems.
Note: Evergreen servers and staff clients must match. For example, if you are running server version 3.1.0, you should use version 3.1.0 of the staff client. Evergreen 3.2.0+ no longer supports a separate client by default, but building a client remains as an unsupported option.
