# What's New in 4.5.0

 The main features of CommandBox 4.5.0 are:

* Ability to install OpenJDK automatically for your servers to use ([read more](https://commandbox.ortusbooks.com/embedded-server/configuring-your-server/custom-java-version#automatic-java-download))
* Environment Variables in the shell ([read more](https://commandbox.ortusbooks.com/usage/environment-variables))
* Support for Forgebox Enterprise (TBA soon)
* JRE Bundled CommandBox installs now use OpenJDK instead of Oracle JDK
* TestBox Code Coverage integration ([read more](https://commandbox.ortusbooks.com/testbox-integration/test-runner#code-coverage))

I already wrote a fairly comprehensive overview of the new features and big fixes here.  Go read it:

Note, there are two backwards incompatible changes.  The first is we turned OFF directory browsing by default on servers.  You can easily get the old behavior back with

```bash
config set server.defaults.web.directoryBrowsing=true
```

The second is that unhandled errors in the shell no longer show the stack trace (you probably wouldn't have noticed if I didn't tell you!)  Get the old behavior back with:

```bash
config set verboseErrors=true
```
