Revision as of 13:05, 20 November 2013

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 a specific security concern or 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).

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

Installation Steps

Upgrade Steps

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.

Steps to Apply a Patch Set

IMPORTANT: Before you begin please ensure you are running the version required by the patch. Patch Sets contain only the files that have changed between the previous release and the Patch Set Version. Therefore they can only be applied if you are running the immediately previous release.

The previous release version that these patch sets are designed for is clearly indicated as the first and smaller number in release notices providing the patch set download link.

1. Download the patch set
2. Unzip the patch set files
3. Upload the files to the root directory of your WHMCS installation
4. Visit the admin area of your WHMCS installation to trigger the version number bump and complete the process

No install or upgrade process is required.

Troubleshooting

What to do if you get a Down for Maintenance or Upgrade in Progress message after uploading a patch set

If after uploading the files from a Patch Set you see a "Down for Maintenance" or "Upgrade in progress..." warning message then this indicates that the patch set files you attempted to apply were not compatable with the version of WHMCS you were running. To complete the upgrade you will need to download the latest [Full Release] version and upgrade using the regular upgrade process as described above.
