5 days ago, the 3.5.9.8 version (A) was released for Windows users:

• You have Windows? Please upgrade to that new version, since it helps the superblock creation
• I call this version (A), because it was officially released!

Today there were more changes committed to the master branch (this is still versioned as 3.5.9.8: let me call this (B) version) which also benefit Linux users.

Before we continue, a note first:

• as always, first make a !backup... you never know what kind of bugs are sleeping in new versions
• a few users are running version (B) already since at least a few hours, and they can: stake blocks, no crashes happened, CPU/RAM seems in normal levels, ...
• this is no call for all users to upgrade now to (B)... but: if you wanna help, you could self-compile (B) and give some feedback. I'm sure someone could also make some compiled versions (also for Windows).

Here some pics of the new features in (B):

"ResearchSubsidy is the amount one would receive for research (excluding interest + fees) if you were to stake at that moment." (further info here)

And some more info in getblock/getblockhash:

Here are some more "appetizers":

• fix spontaneous high CPU usage
• fixes for block staking
• removed newbie boost
• code cleanup
• fix lots of languages/translations
• read more in the changelog

OK, you got curious and wanna use (B) ? 

• Go ahead ;-)
• Feedback appreciated in bugtracker, IRC, slack, telegram (can be accessed via IRC also), ...
