Still no means of identifying if a change of version of TZ data results 
in a change to a local time? At the end of the day which ever software 
is being used, if I provide a UTC normalised time then it also needs to 
identify the rule set used to create it. If different software uses 
different ways of storing the rules it is somewhat irrelevant as long as 
they all produce the same local time so any improvements to the rules 
should include version information. Something that has been missing for 
too long now.
