How are bug fixes provided?
Between new releases, we periodically make minor bug fix updates available, via the Updates page on this web site. These fix known problems in the current release and are signified by a revision letter (e.g. the first bug fix update after the initial release of version 8.0 would be v8.0a). Bug fix updates are specific to a particular release (e.g. to install a 8.0a update you must own a v8.0 licence). We do not have a fixed bug-fix update schedule. Exact frequency depends largely on the number and severity of bugs which have accumulated. Several bug fix updates are usually uploaded to our web site between new releases. Bug fixing for a particular version number stops when a new release becomes available. Bug fix updates for earlier versions normally remain available on our web site for several years.
