Subject: Disallow changing the languageCode of existing languages
X-Git-Tag: 6.0.0_Alpha_1~202
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f3951adda52b0d19cc4387f0c7c71defaec6e14d;p=GitHub%2FWoltLab%2FWCF.git

Disallow changing the languageCode of existing languages

Changing the language code for an existing language effectively invalidates
everything that is already stored within that language and thus is not a useful
operation. Changing the country code or locale should be compatible with
existing phrases or contents and thus is still allowed.
