The rendering of man_made=breakwater is filled in multipolygons and not in closed ways.

That is because the defaults have changed: closed ways that are not tagged with area=yes, are no longer being treated by default as an area for man_made=breakwater. Since multipolygons by default are areas, this issue does not affect them.

The setting change is because there was a conflict with linear ways of man_made=breakwater, in the sense of ambiguity: is a closed way always an area? No, it could be a circular way (think dikes), that needs to be treated as line object instead of area.

By no longer treating the closed way as an area by default, you can resolve the ambiguity by explicitly setting area=yes on the man_made=breakwater features. It should then render as area again. So that is your solution: set explicit area=yes for all breakwaters that are true areas.

Correct. All tags that can both be areas and lines are always treated as lines now, unless they have an explicit area tag. This is true even if they are closed, to avoid confusion. I doubt circupar breakwaters exist, but behaviour was made the same for all features, for consistency reasons.

OK .Will document in wiki.

There exist a list of the features that have their default changed so their wiki pages can be updated?
