Re: Upgrade question
Yeah I've been thinking about that and plan to add a version table to a future release and possibly try to implement automatic upgrades soon after that.
Since you know you have 2. something, then take a look in the 2-0 to 2-1 upgrade script and see if your db already has the columns that are beinng added in that script. If not then run that script.
There are no upgrade scripts to run after that since no schema changes since 2.1, just use the latest stored procedure script and it will upgrade your stored procedures (only applies to MS SQL and PostgreSQL since the others have no stored procs)
If you are working with the source you may also see the script upgrade...tonext.sql, don't run that one as it is work in progress for a future release.
Hope it helps,
