User Settings: Language pack error message is wrong
This error message in the module User Settings isn't really helping:
"The selected language is not available before the language pack is installed.
You can use the Extension Manager to easily download and install new language packs."
Since no language pack in TER is for 4.0x it's useless and misleading.
So give a link to http://126.96.36.199/typo3/t3l10n/typo3conf/l10n/status.html and specify that csh_yourlanguage from TER are deprecated.
I had time to forget about the new localization between 4.0 and 4.0.3...
