Bitcoin Classic 1.2.3

March 22, 2017. Following a string of issues with code that Classic borrowed elsewhere, we finally took responsibility for the adopted code and fixed a lot of issues in that code which directly affect stability and reliability of a node.

Additionally, this feature makes the existing flag -use-thinblocks a proper flag which allows the operator to fully turn it off, making the code of this feature unable to be executed by misbehaving networking nodes.

On top of that, this feature makes the existing flag -use-thinblocks a proper flag which actually turns off codepaths to this feature should the operator turn it off.

We recommend Bitcoin Classic version1.2.3 for everyone, especially if you already were running a version with thinblocks (xthin).
