What's new in this version:

- Added official Greek translation.
- Updated the official Catalan, Czech, Danish, Finnish, French (Standard), German, Hebrew, Hungarian, Italian, Japanese, Norwegian (Bokmal), Polish, Portuguese (Brazil), Portuguese (Portugal), Russian, Serbian (Cyrillic), Serbian (Latin), Slovenian, Spanish, and Ukrainian translations for the changes introduced by the previous version.
- Demoted the official Basque and Slovak translations to unofficial because of a lack of updates by the maintainers. 
- Fix: The Preparing to Install wizard page's detection of files that need to be updated but are in use or queued (by some other installation) to be replaced or deleted on the next restart did not work for [Files] and [InstallDelete] entries with a Components or Tasks parameter.
- Minor tweaks.
