1.2.2 with kaspad v0.12.15 and Bitmain support

All users should update to this latest release (or pull the latest version of main for self-builds / docker installations) as it updates the kaspad dependency to take advantage of the bug fix released on 2023-12-16.

Changelist

• Adds support for Bitmain Kaspa ASICS.
• Updated kaspad dependency to v0.12.15
• Fixes diff initialization bug which sometimes caused disconnects/shutdowns at start
• Buffered logging

1.2.1 with ASIC invalid share fix

Adds workarounds for invalid (low diff) shares on IceRiver / Bitmain ASICs, so they can continue selling their broken-ass devices without putting in the effort to fix the problem themselves.

Default settings (var_diff: true, shares_per_min: 20) should now be fine for all devices. For current ASICs, you'll need to set the existing parameter 'extranonce_size: 2' as before, as well as a new parameter 'pow2_clamp: true'. See the README and/or config.yaml for further details.

1.2.0 with vardiff

Adds a vardiff option, enabling multiple miners with significantly different hashrates to be connected to the same stratum bridge instance, with the appropriate difficulty automatically decided for each one.

1.1.8 with IceRiver support

DO NOT USE THIS RELEASE ANY MORE FOR ICERIVER ASICS.

IR ASICs are sending large numbers of invalid shares, and this release does not reject them. That means the reported hashrate is false. Also, a workaround for these errors has been added to 1.2.1 which should increase your true hashrate.

IceRiver ASIC support

Adds support for IceRiver ASICs, though special configuration is still required, specifically a 2 byte extranonce, as well as an increased minimum share difficulty. Without these settings, you may experience lower than expected hashrates. Please see the README for details.

Docker updates

Docker recipes now build the bridge from source rather than pulling down pre-built images.
