As you already noticed entware-ng (http://pkg.entware.net/binaries/mipsel) doesn't get updated anymore.
The repo on github is archived (read-only) and all the development moved to entware repo.
It now supports MIPSsel with kernel >= 3.4 which means john's fork (+ older merlin installs) and freshtomato are left without an updated repo.
For my own usage I've found some time to update and compile...
