I have a question regarding security updates in LTS editions, in concrete Ubuntu 16.04 LTS.
What is the policy for offering security updates? Recently there was released version 52.9.0 fixing some security issues, but not on Ubuntu 16.04.
Thunderbird is in the main repository, so it should get security updates for 5 years. Is this different for Thunderbird, or does it just take a little bit longer?
