During the last weeks we have prepared a larger update for our Gentoo based VMs. It will include many basic libraries as well as added support for Python 3.5 and 3.6. A detailed list of affected packages and changes can be found as usual in our ChangeLog. Please review the list of updated packages for libraries and tools that may have compiled into your applications. While we have tried to avoid link-level compatibility issues, a small chance remains that applications will not start afterwards due to dynamic linkage problems. Recompiling usually solves this kind a problem.
As the update is a bit bulky, we opted for a staged roll out during the week. Each VM will get an individual scheduled maintenance slot according to the agreed pre-announcement period. Development and staging VMs will already receive updates during this weekend.
Please feel free to contact our support if you need assistance.
