Releases

This page defines and explains the different types of releases we make and the different distribution options we use and how you can apply and use each of them.

Release Types

Feature - A feature release introduces major new features and functionality. It is denoted by a bump in the MINOR version number - x.X.x. It will also contain bug fixes and other maintenance related updates as detailed below.
Maintenance - A maintenance release addresses bugs and usability issues within the WHMCS product. It is denoted by a bump in the MAINTENANCE version number - x.x.X. It may also contain minor features, and/or additions/improvements to existing features.
Targeted Security Release - A targeted security release contains changes to address one or more security concerns identified within the WHMCS product. It is denoted by a bump in the MAINTENANCE version number - x.x.X. Related maintenance issues either introduced by a previous TSR or providing considerable impact to users may at times be included but no regular or scheduled bug fixes will be provided as part of a TSR release.

Distribution Types

Full Release

A full release distribution contains all the files of a WHMCS product installation. It can be used to perform a new install or update an existing installation (regardless of previous version).

It is denoted by the presence of _full within the zip folder filename.

The latest full release can always be downloaded from our members area at: https://www.whmcs.com/members/clientarea.php

Patch Sets

Patch Sets are often provided containing only the files that have changed between the immediately previous release and the Patch Set Version. We provide these to make updating both quicker and easier for those of our customers who stay current and up-to-date with the latest WHMCS releases. By including only the changed files, patch sets have less files to upload which makes the upgrade process quicker and simpler for you to perform.

These will always include _patch within the zip folder filename to indicate they are a patch rather than full release version.
