Use of v3 api

Hi,

The current GitLab on gitlab.com is erroring on some of your examples and scripts, saying the api/v3 is no longer supported and should use api/v4 instead. For example:

% curl -s -H "PRIVATE-TOKEN: **************" "https://gitlab.com/api/v3/projects?per_page=1000" 
{"error":"API V3 is no longer supported. Use API V4 instead."}

Regards, Roger
