What is Early Access Program (EAP)?
We at JetBrains believe that making tools for developers should greatly involve listening to developers. Our Early Access Programs let development community closely participate in discussions about product and influence development planning, from early stages onwards.
Why should you try 2017.1 EAP builds?
Early Access Program lets you evaluate brand-new features as well as many important bug fixes for already existing functionality that will be added to the next release. You can install PyCharm 2017.1 EAP along with the stable PyCharm 2016.3 installation and get regular updates for both.
Please note that features marked pro only are supported only in PyCharm Professional Edition.
