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.
It is important to distinguish EAP from traditional pre-release software. Please note that the quality of EAP versions may at times be way below even usual beta standards.
IDEA 10.5 is free upgrade for IntelliJ IDEA version 10.
Plugin Development Kit: Since the open-source Community Edition was released, we no longer provide the plugin development kit as a separate download. Please see http://www.jetbrains.org/display/IJOS/Writing+Plug-ins for instructions on setting up a plugin development environment.
JDK 7 support
New nonmodal replace text control with instant preview of replacements (e.g. easier regexps)
Tons of bug fixing
The recommended way to get notifications about new EAP builds is to follow @intellijidea on Twitter. Alternatively, you can subscribe to the build announcements as an RSS feed, or create an account in Confluence and watch this page in order to get e-mail notifications about new builds.
