I am pleased to announce the release of WHMCS V4.0.1.
This patch release contains file updates only with no database upgrade and addresses all problems reported and fixed to date since the V4 release at the start of the month. It is a collective update containing all the individual patch releases posted in the bug reports forum. A full list of what's contained in the update is below.
Both changed files only and full install releases of V4.0.1 are available for download in the client area in the usual way (My Products & Services > View Details > Downloads). For those running V4.0.0, the upgrade process is simply a case of downloading the changed files and uploading to your install. There will be no downtime or backups necessary.
