I upgraded a Rails application from 3.2.16 to 3.2.22.2 in a deploy yesterday afternoon (about 13 hours ago), but New Relic still says
Our latest report on this application shows the following outdated frameworks which may be susceptible to security attacks:
rails (3.2.16)
See rails for up to date information on specific vulnerabilities. Was this notification useful or not?
Does it take a while for New Relic to get informed about what version of Rails is being used?
Is your application running on more than one server? If so, were the other servers updated as well? The message will persist if any server is running the older version.
