The sixth item I have is:
* The default behavior for Set, AGI, and pbx_realtime has been changed
to implement
  1.6 behavior by default, if there is no [compat] section in
  asterisk.conf.  In
  prior versions, the behavior defaulted to 1.4 behavior, to assist in
  upgrades.
  Specifically, that means that pbx_realtime and res_agi expect you to
  use commas
  to separate arguments in applications, and Set only takes a single
  pair of
  a variable name/value.  The old 1.4 behavior may still be obtained by
  setting
  app_set, pbx_realtime, and res_agi each to 1.4 in the [compat] section
  of
  asterisk.conf.
 
I guess that referrs to the following in the 1.6 upgrade file:
  You now only need to quote strings in configuration files if you
  literally
   want quotation marks within a string.

Thanks much for that clarification.
