This means, a customers is forced to spend money for a new release in order to get Bugs fixed.
Customers spend money on he FMI's promises of certain functions and reliability. Fixing bugs to fulfil this promises is part of the deal.
FMI should constantly maintain and bug fix last 2 releases.
Take note that some customers must stay with older FM-Versions due to system requirements. They should not let left behind.
