How to Upgrade from 3.1.2 to 3.2.0

[davetest]

One thing of note is if you are using a custom admin folder youll have to do the renaming.

I've upgraded from 3.1.2 to 3.2.1. I use a custom named admin directory which used to work ok, but I get:
Fatal error: Call to undefined function exec_action() in /home/*******/index.php on line 37
for both front end and back end. I've made the correct entry into gsconfig.php. If I rename admin directory to admin it works ok.

Can somebody test this on their own install for me and confirm if renaming admin directory works with latest stable version.

Thanks
