Summary
There is a compatibility feature in v1 sync. While building compatibility layer for v2 sync (Lua Control Plane), we found that it is making things too complicated. Thus we decided that when DP version is older than CP version, we can just fallback to v1 sync until DP is upgraded to same level and it can utilize the v2 sync again.
This code here hides the CP capability of
kong.sync.v2when older (than the CP) DP connects to it. The DPs can already fallback in that scenario, so this code is just for the control plane.I don't think this needs a changelog. It is not a fix. It is very tiny too, and the first time we ever need this is when we release 3.11.
