how do release numbers work?

every qm release is identified by a number such as 1.4-3 where this comprises the major release, the minor release and the build number.

major releases correspond to the introduction of significant new functionality. it may be necessary to purchase an upgrade licence to move to a new major release level. major releases will normally be infrequent but our licensing policy includes provision of free upgrades to users who have only recently purchased their previous licence. we will continue to supply bug fixes to previous major releases for a period of at least one year except where the nature of the fault makes this impossible.

minor releases correspond to the introduction of less significant new functionality. existing licences can usually be carried forward from a previous release.

the build number, reset at each minor release, identifies the specific product build. new builds are uploaded to our web site as often as required to fix problems reported by users or to introduce new features that do not warrant a change of release number. because we try to respond to our customer wishes as quickly as possible, it is not uncommon for us to a post new release within days of its predecessor. whilst users do not need to take every release, it is recommended that users should upgrade to the latest build periodically or when a feature of interest appears in the what's new in recent releases? list.
