AppErgo v0.9.7 updates the architecture of the site and its tools to support 10 languages: English, French, German, Spanish, Italian, Portuguese, Russian, Japanese, Korean and Chinese.
Tools can now have their own interface in each of these languages. A few technical and translation fixes will still be introduced gradually.
AppErgo v0.9.6 replaces the old French / English bilingual menu with a new multilingual selector covering the 10 languages available on the site: French, English, German, Spanish, Italian, Portuguese, Russian, Japanese, Chinese and Korean. This makes it easier to switch from one language version to another and discover the different versions of AppErgo.
AppErgo now has its main X handle: @AppErgo. This account is now the project’s official account for news, new tools, and major announcements in English.
The @AppErgoFR account remains dedicated to French-language posts, while the former @AppErgoHQ account will continue to be used for other languages.
Follow AppErgo via two RSS feeds: all website updates, or only Projects & Forge activity.
