I forgot to mention the other non-NTP config change I noticed in 24T2. 
My IOS object-groups were changed.  When I first created object-groups 
in IOS there wasn't an option to define just a single host.  It was 
added in a later T release.  To get around this I defined a range of a 
single IP (ie, 1.2.3.4 to 1.2.3.4).  I never went back and changed them 
after the 'host' option was added.  When I upgraded to 24T2 it changed 
all those range lines to host lines.  Not a bad change but another 
unexpected one.
