v0.5
Pre-release
v0.5 brings important changes to training data generation for speed, and critical bugfixes in the way that history was sent to the net and moves were received. We also now have fractional temperature support for variety in match games, so we should see more opening variety.
Upgrading is required - however, thanks to some great work by Andy Olsen (killerducky), the lczero client remains backwards compatible with old network files.
For UCI users, the engine now defaults to "weights.txt" if no weights parameter is supplied. Also, you can use the "--uci" flag to have it delay initializing until isready is sent, which should fix problems loading in GUIs like Fritz. Time management is also improved.
