Anyone up to date what is going on with Ethereum?

Looking at Ethermine it looks like the ProgPOW audit should be released in Late August which is now. Also it looks like the ETH devs have finalized the next Ethereum fork (Istanbul) and looking at the EIP posted it doesnt look like there is any type of algo change in there.

Anyone know what is going on with ProgPOW? I remember watching a ETH dev conference and they said they are going to go with ProgPOW unless they encounter difficulties however since then we haven't heard much.
