PUN Classic (also called PUN1) is the original and first major version of PUN.
It is now replaced by PUN2 which is refactored and enhanced.
We highly recommend starting new projects with PUN2 and if possible migrating existing ones from PUN1 to PUN2 by following our "Migration Notes".
PUN Classic will be maintained for the coming months.
We will fix important bugs and support new Unity versions but new features will be added only to PUN2.
