# >current release 0.9.7.4 ### Release information[ΒΆ](https://github.com/opencats/gitbook/blob/main/broken-reference/README.md) The current OpenCATS release is 0.9.7.4 and the most recent release will always be available at #### Dependencies The main dependencies for this software are PHP and MariaDB. PHP 7.2 and MariaDB 10.6 are the most recent versions supported. **Higher levels may work, but are untested** **Note:** MySQL is now unsupported due to some divergence between MariaDB and MySQL. MariaDB is a drop-in replacement for MySQL. Additional utilities (antiword, html2text, unrtf, etc) are necessary for full-text indexing of uploaded resume's. These are not required for installing OpenCATS, and can be added in later. #### Which package to install? If you want a simple install, then please check you've downloaded and installed the \*-full package on the releases page and not the source code or have cloned the master repository. If you've done either of the last two, you'll need to download and run composer [https://getcomposer.org/)](https://getcomposer.org/) to pick up the dependencies which are already bundled in the -\*full package.\ **To avoid pulling in development packages, run composer install with the --no-dev option** ``` composer install --no-dev ``` ### and finally - a gentle warning This documentation is coming along nicely, albeit slowly.
