If you are running IntelliJ IDEA 2016.1, go ahead and click Check for Updates to install the patch right from the IDE. Otherwise, you’re welcome to download and install the new version from the website.
As always, we appreciate your feedback here in comments or directly in our issue tracker.
UPDATE: Don’t worry if you notice a confusing message in the Updates dialog saying that you can evaluate the new version for 30 days, or buy a license key or upgrade online. This is a known problem that will go away after you’ve updated.
Develop with pleasure!
