I shall say what everyone is thinking, yet no one dares to say...
DEM. PATCH. NOTES.
patch notes will be released as usual late afternoon the day before. So Monday some time probably between noon and 4pm CDT. Unless there is an exploit at which point they'll wait until fixed but since this 2.8 you'll get patch notes on Monday..and given their long term history... Wednesday*
* There have not been much need for hot fixes, kudos on that.
