Installer page translations have not been updated

I had a problem with some pages not being translated automatically in a french locale while compiling the installer framework 3.0.4.

I found this after updating the .ts files with lupdate:

Found 576 source text(s) (267 new and 309 already existing)
Removed 255 obsolete entries
Number heuristic provided 5 translation(s)
Same-text heuristic provided 14 translation(s)

There seems to be a lot of small modifications to the text that have not been re-translated over time.

Could we have up-to-date languages translations? I could do it for french...but not for all other languages that have the same problem. It seems some translations are more updated then others.

Example: QInstaller::TargetDirectoryPage

"Please specify the folder where %1 will be installed."

Became:

"Please specify the directory where %1 will be installed."
