Blockchain height 1788000 has just passed, so if you’re mining monero, you have to use the new miner.
Good news: Performance is roughly where I’d want it to be:
Bad new: I did (of course!) introduce a final bug when I built the release last night, so the v0.15.1 version currently on the downloads page will actually crash at that blockchain height. (Apologies – but that happens when you can’t actually test on the ‘real’ blockchain, yet :-/). The fix was literally 10 lines of code … but still – I’m currently baking the new version, and will upload as soon as the make is through.
