New in Google AJAX API
03 September 2008It is now possible to load any API at any state of page loading: Dynamic Loading. Before that it was only possible to put <script> in the page <head> before a full load (w/o using hacks, of course). Dynamic Loading allows to postpone the loaders loading even.
Also, they added (UPD 2011-01-10: and deleted) the possibility to guess users geo location. Approximated but on the other hand quick and free.
