This release includes continued improvements to the library, fixes for a
number of lexers and support for three new languages:
https://github.com/rouge-ruby/rouge/releases

When `ReactiveCachingWorker` hits an SSL or other exception that occurs
quickly and reliably, automatically rescheduling a new worker could lead
to excessive number of jobs being scheduled. This happens because not
only does the failed job get rescheduled in a minute, but each Sidekiq
retry will also add even more rescheduled jobs.

In busy instances, this can become an issue because large numbers of
`ReactiveCachingWorker` running can cause high rates of `ExclusiveLease`
reads to occur and possibly saturate the Redis server with queries.

We now disable this automatic retry and rely on Sidekiq to perform its 3
retries with a backoff period.
