Subject Re: change ActiveMQ 4.2 to ActiveMQ 5.0
Date Tue, 23 Jan 2007 19:00:53 GMT
Hi Brian,

this isn't exactly true - we have always incremented the major  
version number with wire protocol changes when they are not backward  
compatible - but it's erroneous to assume that there is a casual link  
between the two - its just been coincidental to date.

cheers,

Rob
