Good morning!

• We received the Ripple payout code and are in the process of evaluating it now. The code requires the mbstring extension to be installed, so we have to recompile PHP again with both pthreads and mbstring (because pthreads is not in the official binaries.) Once we've verified the code, we'll then move on to the database work, with a goal of having Ripple available a week from now.
• We're aware of a problem with two-factor authentication QR keys being reported as invalid for some customers. Fortunately, we finally figured out why we can't reproduce it - the error only occurs on Apple products. We need to order an iPhone for testing, which will probably take a week for the purse.io bidder to accept and for the phone to arrive. Once it arrives, Constance will try to reproduce the problem with the iPhone and resolve the two-factor QR codes issue. We are not aware of any other brands of phone having this problem; if you own a non-Apple product and have QR code issues, please let us know so we don't waste time ordering this phone.
• We resolved the SHA-256 connectivity issues. The problem was when Bitcoin Cash would come up as the most profitable coin. The CashAddr format is new and therefore not compatible with our system, and it caused exceptions. We disabled Bitcoin Cash mining for now and will re-enable it after we figure out how to handle CashAddr addresses.
• Some customers are reporting that equihash miners are disconnecting. The problems are caused by the mining software, which assumes that pools will mine ZCash, a coin that has relatively short block times. It seems that some type of software is configured to time out after 12 minutes when a new block hasn't been found. This is incorrect behavior; there are many times we mine coins that are not being mined by anyone else, and therefore there won't be a block until we find it. Look into the software's configuration settings and change them so that the software does not assume that no blocks equals wasted work and time out after 12 minutes to resolve this problem.
