New version: 3.0.0, 22nd April 2013No, not the BFL ASIC code yet. As soon as kanoi and/or I have one, we'll have a release that supports them which should be pretty soon. This is the first release officially supporting Avalon ASICs. Lots of work under the hood, but very little to GPU mining.
Human readable changelog:- Avalon support. Note this still uses the old serial-usb interface but is far more reliable than the earlier firmware release versions. If I get a lot more time to hack on an avalon I will update the code to use direct USB the way we're planning for BFL ASICs.
- Drop all CPU mining code.
- Changed default worksize to 256 for scrypt mining.
- Fixed a rare crash on stratum pool drop outs when built with older libcurls.
- Fixed potential deadlocks.
- Fixes for some flaky hardware that would frequently drop stratum connections.
- Fixed detection of solving a block, and restart work if we know we solved it.
- Lots more readme updates.
- That's all.
