Require Ruby 2.0.0+
The agent no longer supports Ruby versions prior to 2.0, JRuby 1.7 and earlier, and all versions of Rubinius. Customers using affected Rubies can continue to run 3.x agent versions, but new features or bugfixes will not be published for 3.x agents. For more information, check out our community forum.
OkJson vendored library removed
Ruby 1.8 did not include the JSON gem by default, so the agent included a vendored version of OkJson that it would fall back on using in cases where the JSON gem was not available. This has been removed.

yajl-ruby versions prior to 1.2 had the potential to cause a segmentation fault when working large, deeply-nested objects like thread profiles. If you are using yajl-ruby with the
JSONmonkey patches enabled by requiring
yajl/json_gem, you should upgrade to at least version 1.2.
