Hello, we have released a new Psycopg package 2.7.6.1. There is no code difference w.r.t. 2.7.6, but we have fixed the OS X build as an upgrade in the Travis infrastructure rendered the binary packages broken for OS X 10.12 (ticket #807).
While investigating what originally seemed a regression in the libpq (ticket #808) we tried upgrading the libpq used in the binary packages to 11.1. That was a red herring, but the updated libpq made it to the package. Please don't break anything else ;) -- Daniele
