I didn’t found any official particular documentation, what I need to do to update library version in registry?
https://docs.platformio.org/en/latest/librarymanager/config.html#version if the version number is updated the crawler should automatically update your library in the registry. I can’t find it in the docs right now but this might take the crawler a day or so to update, as he isn’t checking for updates constantly I suppose.
Sometimes you just need to know where to look … I only know as I asked Ivan at some point.
Updates to existing libraries are done every 24 hours. In case a more urgent update is required, you can post a request on PlatformIO community.
