release 3.0.0 of rmr2 is available. Please keep in mind that the package is still called rmr2, despite being version 3. This release is mostly devoted to efficiency, see the
Changelog for details, and prompted by an emphasis on use cases that are more common since the release of plyrmr. Despite having only minor changes to the API, this is a major release that brings major changes to the serialization format, so be sure to do your own testing before deploying to production. Comments and feedback are welcome.
