John, helaas ...
You need to see each line as one step. So you have to do 11 individual updates to become current.
When you extract the downloads you will find a
CONTRIB folder which has the instructions for each update in a separate subfolder. The first one will be called
update_0_3_1_to_0_4_0-RC1. Open the
UPDATE.XML you find there and simply follow the steps.
Some of the updates require several files to be edited, some only one or two, but the instructions should be clear.
Make sure you have a good backup just in case you make a mistake.
Personally I would do only 1 or 2 updates at a time, and then first let the gallery run for one or two days, then do the next. This both to not get too frustrated with the work, and to make sure you don't introduce errors along the way that you only find after you have done multiple updates.
Veel plezier,
Marc
