## Notable Changes in IntelliJ Platform 2019.2
`com.intellij.openapi.fileTypes.FileTypeFactory` deprecated
: When registering file type via file extension matching, use extension point `com.intellij.fileType` instead (see [Sample](/tutorials/custom_language_support/language_and_filetype.md#b-register-file-type-20192-or-later)).
Unbundled plugins in IntelliJ IDEA
: Several plugins for no longer actively maintained technology have been moved to a [separate repository](https://github.com/JetBrains/intellij-obsolete-plugins/). If your plugin depends on them, users will need to install them from the [JetBrains plugin repository](https://plugins.jetbrains.com).
