Changes in v2.8.18

I noticed one of the changes in the changelog for v2.8.18 was:
“fixed - WDS disconnect/reconnect”.

Can I get some more info on this? I have a WDS link that has been fairly problematic but I always assumed it was due to the WDS client on the other end. What are the characteristics of the original problem that has now been fixed?

It simply disconnects and reconnect quickly. The user may barely notice.
