 # Changelog
 
+## v3.2.2
+
+- Improve performance of `--list` and `--summary` by skipping running shell
+  variables for these flags
+  ([#332](https://github.com/go-task/task/issues/332)).
+- Fixed a bug where an environment in a Taskfile was not always overridable
+  by the system environment
+  ([#425](https://github.com/go-task/task/issues/425)).
+- Fixed environment from .env files not being available as variables
+  ([#379](https://github.com/go-task/task/issues/379)).
+- The install script is now working for ARM platforms
+  ([#428](https://github.com/go-task/task/pull/428)).
+
 ## v3.2.1
 
 - Fixed some bugs and regressions regarding dynamic variables and directories
