I'm woking on a new client version that will include changes from Bitcoin 0.8.6 to 0.9.1 besides some Riecoin specific speed improvements. It's a lot of changes, and Bitcoin has changed so much that cherry-picking or rebasing commits results in lots on conflicts that have to be manually merged, that's why it's taking longer than expected, but the good news is that we'll have a much better client soon.
There will be a Windows installer, and also 32 and 64 bits versions for Windows. This means block verification will be much faster for Windows users with 64 bits CPUs and OSs.
Regarding the miners, keeping miners updated with all the latest optimizations is a lot of work so I'll focus on an xpt to stratum proxy.

Thanks Gatra!
Would the 0.9.1 include the improvements from dga's xptminer? Also, would there be an independent solo miner that incorporates dga's improvements? or does it make sense to have an xpt to stratum & GetBlockTemplate proxy?
