The combo loader also allows us to specify which YUI version to load via a tweak to the url. In this way we can easily test new version of YUI side by side with the current stable version as they come out. This allows Launchpad to keep with future YUI released much faster.
We’ve still got more to do though. YUI just released version 3.7 and we aim to push that into production faster than ever before. Please let us know how these changes work for you.
Launchpad also wants to thank the folks over at YUI for continuing the great work on a tool that Launchpad heavily depends on.
