 [*Bugfixes]
 
 * bugfix: distance for multi-geometries ignored specified distance strategy. Fixed
-* bugfix in difference for polygon/multi_polygon (reported 2011/10/24 on GGL-list)
+* bugfix: difference for polygon/multi_polygon (reported 2011/10/24 on GGL-list)
 * bugfix: raise exception for calculation of distances of multi-geometrie(s) where one of them is empty
 * bugfix: multi DSV did not correctly use settings, fixed
 * bugfix: self-intersections could sometimes be missed (introduced in 1.48), fixed
 * bugfix: convex hull crashed on empty range (e.g. empty multi point), fixed
 * bugfix: area/centroid/side/intersection/distance did not work for "int" type filled with large (but not overflowing) integers. Fixed.
 * bugfix: disjoint/intersect did not work for degenerate linestrings. Fixed.
+* bugfix: covered_by did not compile for a ring. Fixed.

 [*Documentation]

 [*Internal changes]
 
 * updates in specializations/not_implemented for distance/convert/assign/area/with/covered_by
 * move of wkt/dsv to io folder, making domains redundant
 * warnings: strategy concepts assigned to zero to avoid clang warnings (patched by Vishnu)
-* warnings: there were several unused parameters, for which gcc/clang warned. Fixed.
