Okay, I think I understand now. If you haven't switched to the new system, you won't be able to pull in the new changes because they're not being posted in the old repository any more. Mark and Fu stopped mirroring the changes in both places after the last code push.

When you were told you could keep working "the old way," that referred specifically to the patch submission process, not the update process. You are still able to submit patches through Bugzilla instead of having to create a Github pull request. But if you want to work against the very latest code, you will need to download it from the git repository.

I'm sorry if this is upsetting for you! I know it's a lot to take in and there hasn't been a lot of communication because the kinks in the process are still being worked out.
