New fare rules are now in effect:

Basically as described before, with Sale fares replacing Saver and giving a 50% refund, Value giving a 75% refund, and Flex giving a full refund. The refund/cancellation policy for rooms remains the same as it has been, so eVouchers will still be a thing. In looking at fares it seems flex generally costs only 10% more than value. Also, all non-Acela business class and Acela first class fares are flex fares.
