For Debian/Ubuntu users installing via our repo, please update your APT source (seeHERE).
Currently we only support MongoDB 3.4. We're working on updating support before end of life this fall. We have instructions for Ubuntu users in our HC article HERE (see section 2.2).
The initial database migrationwill take longer than normal.It is expected to see mongo using most, if not all, of the available CPU cycles during this process. Please be patient, this process could easily take 15+ minutes, depending on the amount of historical stats, as well as the system specs. As always, err on the side of caution, and make a backup before upgrading.
*This release follows our usual release structure which means it will initially be available via this blog post only. It will be posted to the download site and official repos in the near future. If you aren't familiar with our release structure, please take a moment to read our post HERE. Thanks!
