Re : how to upgrade 1.9rc2 -> 1.9current
Don't forget also to run tiki_1.8to1.9.sql for all the database changes that occurs between the 2 versions
(The database can change and has changed until the first release is out)
msql -u user database -p xxxx -f < db/tiki_1.8to1.9.sql
A lot of errors will occur but don't worry
