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 passed (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).
However, if someone tried a nightly build and reported us a problem which is critical, we add corresponding notes to the builds table. Also after some period of testing (e.g. 1 day) if there were no critical problems reported/found, we've add "Stable" mark for the build.
