Can someone test this page: http://flex.apache.org/installer.html and let me know if you are seeing 4.10 or 4.9.1 in the installer badge? Please clear your cache and try as well to see if there is a difference.
For me, it has switched back to 4.9.1 and the badge is loading installer config 2.0. Did someone push a new badge build? Or is our website messed up? Thanks, Om
