Alright, the new core wallet is almost ready, but don't feel overly rushed as this version requires a mandatory upgrade for pool miners only before block 27500. If you have a lot of pool miners to upgrade you can start pulling down the linux version (1084) now, but I will announce the release soon (when windows is ready).
Oh, you reused the version number 1.0.8.4, there is already now a Ubuntu package named 1.0.8.4 from the commit before
I will build the new one as 1.0.8.4a for Ubuntu, can the next number be 1.0.8.5 to prevent problems? That would be great.
I wasn't aware that the commit c35086028c8a2994ade90f5ff32fc8a0842c50bf wasn't a official release, as it had a version number, too.
