<a href="https://downloads.haskell.org/~ghc/7.10.1-rc1/" target="_blank">https://downloads.haskell.org/~ghc/7.10.1-rc1/</a><br>
<br>
This includes the source tarball and bindists for 64bit/32bit Linux<br>
and Windows. Binary builds for other platforms will be available<br>
shortly. (CentOS 6.5 binaries are not available at this time like they<br>
were for 7.8.x). These binaries and tarballs have an accompanying<br>
SHA256SUMS file signed by my GPG key id (0x3B58D86F).<br>
<br>
We plan to make the 7.10.1 release sometime in February of 2015. We<br>
expect another RC to occur during January of 2015.<br>
<br>
Please test as much as possible; bugs are much cheaper if we find them<br>
before the release!<span><font color="#888888"><br>
