Since version 5.3-005, NetUP stopped the release of UTM5 updates for Centos 5 and Debian Wheezy. That is due to discontinued support of these operating systems by their developers.
We also stopped supporting PostgreSQL due to the features of the UTM5 build on new systems.
NetUP notifies customers about the release of a new version of the billing system. The UTM 5 version 5.3-005-rc1 is a release candidate and is intended for acquaintance with the functional.
We don't recommend using this version of the billing system for commercial operation!
Current UTM5 update contains fix for the bug found during the operation of previous version.
