incompatible change in minor version 0.13.0

[gsar]

app fails to load on boot with the new DelayedJobGroupsPlugin is incompatible with Delayed::Job when 'destroy_failed_jobs' is set to 'true' error. we are not setting this value explicitly anywhere in our code, so it appears it is failing on default behavior?

i understand the reason for the change, but this change should have prompted a major version increment IMHO.

Apologies for any headaches this might have caused! In hindsight, I agree this probably should have been a major version release. To help mitigate this, I'll plan on releasing a minor version reverting these changes and move them into a major version release with more clear upgrading instructions (ie having to explicitly set the destroy_failed_jobs option to false).
