Here we published so called "Nightly Builds" of ReSharper.
What are Nightly Builds?
Nightly builds are builds which are built and published automatically every night without any additional testing from JetBrains' side. Only our internal automated tests are run (if they fail the nightly build is not published). Be careful: there is absolutely NO GUARANTEE that a nightly build will even run! Although you can try it at your own risk and post our feedback (as for EAP builds - into the newsgroup/forum and JIRA).
