You need only install the release on top of your existing installation.
No need to uninstall 2.0 or worry about overwriting changes you have made.
At this time, we do not intend to translate the main site, manual or other documentation. Aside from the staggering amount of work involved in any initial translation(s) of that amount of information, we have issues with resources to host multiple versions, Keeping them up to date with weekly beta releases of Rainmeter would be literally impossible, and any translation is bound to introduce errors and make supporting our users here in the forums impossible. We have no intention of "balkanizing" our forums (and thus our "community") by having areas for help for different languages, we must use English here so everyone benefits from questions and the answers. So all help here will be in English, referencing text from the English manual. Translated versions of the manual can only cause confusion and errors.ghost81 wrote:Rainmeter 2.2 will be even more popular with the translations . The translation of the manuel would great for those who don't speak english.
