     1. At `intellij`, change the version property to the latest version. This is the IntelliJ version used for "runIde". Also adapt the version numbers of all versioned plugins at `intellij`→`plugins`. You can look up each plugin in the IntelliJ marketplace and find the latest compatible version there.
     2. At `tasks`→`patchPluginXml`, change the `sinceBuild` and `untilBuild` property accordingly, the format is explained in a comment there.
     3. Optionally upgrade the versions of the dependencies at `plugins` and `dependencies`, however this is usually not necessary.
