# Incompatible Changes in IntelliJ Platform and Plugins API

> For the complete documentation index, see [llms.txt](https://plugins.jetbrains.com/docs/intellij/llms.txt).

IntelliJ API may be occasionally changed between releases, leading to existing plugins' incompatibilities with newer IDE builds.

See [Verifying Plugin Compatibility](verifying-plugin-compatibility.html) on how to use Plugin Verifier and IDE inspections to check such problems.
