v2.0.0

Tantabus v2 is estimated to be about 250 Elo stronger than v1 in self play tests at short time controls (8.0s+0.08s).
The gains are mostly from large improvements in search and evaluation, with some performance improvements as well.
Huge thanks to Pali (Black Marlin author) for assistance during the development of Tantabus.

What binary do I run?

The releases follow microarchitecture levels.
x86-64-v3 is recommended for most systems.
However, it may not run on older systems (pre-Haswell/pre-Excavator).
x86-64-v2 will run on almost any system.
x86-64 is a baseline binary that will run on truly ancient systems.

v1.0.2

A quick fix to a serious bug where Tantabus could not checkmate in simple endgames. Otherwise identical to version 1.0.1.
