Although we try to incorporate all changes, there are limits to what we 
can do quickly.  It's not just me personally -- it's also the hassle of 
everybody who tries to track the tz database and generate new releases.  
It'd be nice to have a reliable history of Casey's time zone, but I'm 
not sure it's worth cutting a new release merely because they have bad 
weather and their supply aircraft is overdue.

As I understand it, Wilkins Aerodrome is not year-round and so doesn't 
make our cut.
