The current release is v1.0.68, v1.0.277 is a pre-release, so this will probably be in the next release or the one after that. ( https://github.com/mozilla/pdf.js/releases https://github.com/mozilla/pdf.js/releases ) I have recently switched my project from v0.8.1013 (from feb 2014) to v1.0.68 and rendering times have improved enormously. Good to see that there are more improvements coming.
