ouch. such a wide ranging  question!  as Phil says, look at the SX
release notes for particular features and capabilities, but basic run-through

SXD - old and buggy
SXF - 'current' mainline though missing new features
SXH - strange development release superceeded by SXI
SXI - new longterm support release with lots of new features (eg IPv6)
