It can + be extremely hard to mention all the changes we introduced during that + release but we beg you to read at least the upgrade section which describes + the required modifications that you need to do for upgrading your cloud + from 13.0.0 (Mitaka) to 14.0.0 (Newton). + + That said, a few major changes are worth to notice here. This is not an + exhaustive list of things to notice, rather just important things you need + to know : + + - Latest API microversion supported for Newton is v2.38 + - Nova now provides a new placement RESTful API endpoint that is for + the moment optional where Nova compute nodes use it for providing + resources. For the moment, the nova-scheduler is not using it but we + plan to check the placement resources for Ocata. In case you plan to + rolling-upgrade the compute nodes between Newton and Ocata, please + look in the notes below how to use the new placement API. + - Cells V2 now supports booting instances for one cell v2 only. We plan + to add a multi-cell support for Ocata. You can prepare for Ocata now + by creating a cellv2 now using the nova-manage related commands, but + configuring Cells V2 is still fully optional for this cycle. + - Nova is now using Glance v2 API for getting image resources. + - API microversions 2.36 and above now deprecate the REST resources in + Nova used to proxy calls to other service type APIs (eg. /os-volumes). + We'll still supporting those until we raise our minimum API version + to 2.36 which is not planned yet (we're supporting v2.1 as of now) but + you're encouraged to stop using those resources and rather calling the + other services that provide those natively.
