What is Early Access Program?
We at JetBrains believe that making tools for developers should greatly involve listening to developers. Our Early Access Program lets development community closely participate in discussions devoted to IntelliJ IDEA and influence development planning, from early stages onwards.
Early Access Program allows you to try pre-release versions of our software to evaluate features that will be added to the next release.
