Oh okay. Can you please confirm if the support for rolling upgrade (For major version) is in your roadmap? @wey

As for now, between major versions, the RPC and Data structure will be changed, thus down time of the whole system is expected. While this is considered to be mitigated in the future. Another thing is, 3.x will last quite a long time(than previous versions as major features are more stable than it was in 1.x 2.x)

Okay 👍
