It seems in “Service Release Candidate”, there has 8 SR3 version. In “Service Release”, the latest version is SR2. Is there any difference? Could I use “Candidate” version for general working?
That said it is soon going to be promoted to Service Release - if all goes well probably upcoming Tuesday - it should be quite ok to start using this version.
Typically Service Release Candidates won’t receive anymore big changes, we try to stick to stabilization for these, not adding new stuff (in most cases).
If you don’t want to use Service Release Candidates yet you can use CPU rendering until Rhino 8.3 is released as Service Release.
