Hi,
We've just released version 3.0.1 of the driver.
Following the semantic versioning scheme[1] that we recently adopted, this release is a patch release and contains mainly bugfixes that affected 3.0.0, and bugfixes merged from the 2.1 branch. Check the complete changelog[2] for details.
As usual, the driver is available from Maven and as a binary tarball; see the "Getting the driver" section[3] in our online documentation.
Please note that it might take quite a while until the new binaries replicate through all our download servers.
