* BC Break: due to an oversight, the `COMPOSER_BIN_DIR` env var for binaries added in Composer 2.2.2 had to be renamed to `COMPOSER_RUNTIME_BIN_DIR` (#10512)
* Fixed enum parsing in classmap generation with syntax like `enum foo:string` without space after `:` (#10498)
* Fixed package search not urlencoding the input (#10500)
* Fixed `reinstall` command not firing `pre-install-cmd`/`post-install-cmd` events (#10514)
* Fixed edge case in path repositories where a symlink: true option would be ignored on old Windows and old PHP combos (#10482)
* Fixed test suite compatibility with latest symfony/console releases (#10499)
* Fixed some error reporting edge cases (#10484, #10451, #10493)
### [2.2.5] 2022-01-21
