hi john, > What is the relationship between 1.3.8 and 1.5.0? 1.3.8 is the base for the next stable release (1.4) 1.5 is the branch which will lead to 1.6. 1.3.8 can be suggested for productive use. 1.5 not. they are already separated branches since several months and will be more and more different. ciao a.l.e
