The Belle II detector at the SuperKEKB accelerator complex is a super-B factory covering a wide range of exciting physics topics. To achieve the project's research goals, a substantial increase of the data sample to 50/ab is needed, and for that, the luminosity has to reach the ambitious goal of 6 10^35/cm^2/s. The progress towards the design luminosity is accompanied by research and development of the accelerator, detector components, operation methods, as well as their upgrades. The paper discusses the status and plans of the project, timescales for upgrades, their motivations, and opportunities, gives an overview of upgrade options, and finishes with an outlook and perspectives.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
