 # FOSSA CLI Changelog
 
+## 3.15.4
+- Scala fix: Prefer `MiniDependencyTreePlugin` over explicit `DependencyTreePlugin` ([#1627](https://github.com/fossas/fossa-cli/pull/1627)).
+
 ## 3.15.3
 - Remove `fossa snippets` subcommand and documentation ([#1623](https://github.com/fossas/fossa-cli/pull/1623)).
   The `fossa snippets` subcommand has been replaced by `fossa analyze --snippet-scan` ([documentation](./docs/features/snippet-scanning.md)). If you are still using `fossa snippets`, you can temporarily keep using it by using versions of the CLI previous to this release. We will eventually be sunsetting the services that back `fossa snippets`, but will keep them running to mid-February at the very earliest. Once those services stop running then `fossa snippets` will no longer work at all, even when using older versions of the CLI. Please reach out to support@fossa.com if you have any questions.
