The FCC has issued an order that TP-Link open their devices to being flashed by 
third pary firmware. We just need to wait for this to trickle back down to the 
supply chain. It may be that they have a new firmware that you can update to 
that will then let you install OpenWRT

CC doesn't have the latest, but it does have fq_codel, so it's a huge step up 
from the factory firmware.

Most of the OpenWRT developers left to fork the project and now have the LEDE 
project. Most of the development and testing of new stuff is happening there.

Neither project has made a release since the split, but LEDE is working on 
setting up the infrastructure to do a release.

In the meantime, you can install the nightly builds or compile your own.

Part of the question boils down to what you define as the "product" that you are 
waiting for.

OpenWRT/LEDE are very unlikly to have rapid releases, if they do one a year they 
will be doing much better than they have in the past.

Do you need a device that ships with the fixes in it from the factory?

Do you need a stable release of OpenWRT/LEDE?

Do you need the fixes in the master git repository for OpenWRT/LEDE?

Do you need the latest and greatest fixes?

the last one in incompatible with the earlier ones :-)
