Neutron v4.0.2.666 (satanic edition) - Recommended update

With a little help from the dark lord (seeing as this release correlates with the 666'th commit to master (5c3d6c9)), we hereby present version 4.0.2.666 of Neutron - the satanic edition.

Who should update

• All masternodes, stakers, and wallets

Release Notes

• Before accepting a block during a reorganize, double-check so that newly set pindex->pprev is not NULL. If an index has no reference backwards, there is no previous block where we can fetch the money supply for the calculation
• AddToBlockIndex(...) now errors out whenever a we try to write a duplicate block
• These changes should fix the final triggers that can clear the money supply (we hope). If you still experience related issues, please send your debug.log to one of our developers so we can troubleshoot the problem

About binary distributions

• The published AppImages are for 64bit Linux distributions and should work on most relatively recent Linux versions.
• Binaries for both 32bit and 64bit Windows systems are provided.
