The annotations which are used to mark unstable APIs are shown in the list below.
By default, the inspection ignores usages of unstable APIs if their declarations are located in sources of the same project. In such cases it'll be possible to update the usages when you change APIs. However, it may be inconvenient if the project is big, so one can switch off the Ignore API declared in this project option to report the usages of unstable APIs declared in both the project sources and libraries.
