+### Added

+- macos build to releases
+
+### Changed
+
+- exitOnError() removed in favour of a [deferred exit function](https://github.com/onyx-and-iris/q3rcon/blob/cd15e8983726177d6edd985a8bf3d7f4e0d7f346/cmd/q3rcon/main.go#L21), this ensures the closer() cleanup function is always called.
+- the included CLI now uses a [timeouts map](https://github.com/onyx-and-iris/q3rcon/blob/cd15e8983726177d6edd985a8bf3d7f4e0d7f346/cmd/q3rcon/main.go#L109).

+
+# [0.3.0] - 2025-04-05
+
+### Changed
+
+-   `-loglevel` flag is now of type string. It accepts any one of trace, debug, info, warn, error, fatal or panic.
+    -   It defaults to warn.
+
+# [0.2.0] - 2025-02-03
+
+### Added
+
+-   If neither the interactive flag is passed or any command line arguments then a *rcon status* command will be run.

-Log level may be set by passing the `-l` flag with a number from 0 up to 6 where
+The `-loglevel` flag allows you to control the verbosity of the application's logging output. 
+
+Acceptable values for this flag are:
+
+- `trace`
+- `debug`
+- `info`
+- `warn`
+- `error`
+- `fatal`
+- `panic`
+
+For example, to set the log level to `debug`, you can use:

+```
+
+The default log level is `warn` if the flag is not specified.
+
+## Further Notes
+
+This rcon client is fully compatible with the [Q3 Rcon Proxy][q3rcon-proxy] package.
