+  * Fixed interoperability issue with laminas/laminas-zendframework-bridge and Composer 2.2 (#10401)
+  * Fixed binary proxies for shell scripts to work correctly when they are symlinked (jakzal/phpqa#336)

+
 ### [2.2.2] 2021-12-29
 
   * Added [`COMPOSER_BIN_DIR` env var and `_composer_bin_dir` global](https://getcomposer.org/doc/articles/vendor-binaries.md#finding-the-composer-bin-dir-from-a-binary) containing the path to the bin-dir for binaries. Packages relying on finding the bin dir with `$BASH_SOURCES[0]` will need to update their binaries (#10402)
