A quick word to you other translaters:
Maybe you already had this idea yourself, but I found out that it's a good option to have a look at the changelog of new (pre)releases. Here you can see which parts are likely to have gone through changes compared to earlier releases and you might not need to trawl through the whole program to find them. This could save a lot of time, because it can help to find strings that appear in English again, although you've translated them before.
