The pdf version of the Guide to Advancement 2021 was published on the Advancement Resources web page earlier today.
Also forms 126.96.36.199 and 188.8.131.52 have been updated to match the Guide to Advancement .
There have been many changes to the GTA so it would be well worth your time to carefully review the whole document. In particular, sections 4, 7 (totally rewritten), 8, 9, and 10 have important changes in them.
IMPORTANT NOTE: The online version (HTML) is being updated.
