Jump to: navigation, search

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).

A full release version is denoted by the presence of _full within the zip folder filename and "Distro Type: Full Version" within the included README.txt file.

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

Upgrade Steps

Please refer to the Upgrading documentation page

Patch Sets

Patch Sets contain only the files that have changed between the immediate, previous version and the latest version, (ie. a patch set for version 1.1.2 is valid for a 1.1.1 installation and nothing else). 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.

A patch set version is denoted by the presence of _patch within the zip folder filename and "Distro Type: Patch Set" within the included README.txt file.

Installation Steps

Since Patch Sets contain only the files that have changed between the previous release and the Patch Set Version, patch sets are only valid for upgrades and cannot be used for new installations.
