Good question, for the reason you noted below (breaking scripts). If I was to guess I'd say it happened shortly after ARIN assigned their first 32-bit AS number.

Where is the new formatting documented, asn.h ? representation-04.txt contains pertinent words, but I imagine it's not strictly accurate to call that documentation for ARIN's presentation format decisions (although maybe it is, to all intents and purposes, since I seem to think that George's draft mainly seeks to document practice that the RIRs have already agreed on, between themselves).

It just broke a scriptology we use to generate AS lookups for 'offline'
customers (please don't ask :) ).
