 ### Added
 
+- New index::RelationsMap(Stash|Index) classes implementing an index for
+  looking up parent relation IDs given a member relation ID.
+- Add `get_noexcept()` method to all index maps. For cases where ids are
+  often not in the index using this can speed up a program considerably.
+- New non-const WayNodeList::operator[].
+- Default constructed "invalid" Coordinates.
+- Tile constructor from web mercator coordinates and some helper
+  functions for tile arithmetic.
+- Tag matcher matching keys using a regex.
+- New `envelope()` functions on `NodeRefList`, `Way`, and `Area` returning a
+  `Box` object with the geometric envelope of the object.
+- Add `amenity_list` example.
+
 ### Changed
 
+- Replaced the implementation for the web mercator projection using the usual
+  tan-formula with a polynomial approximation which is much faster and good
+  enough for OSM data which only has ~1cm resolution anyway. See
+  https://github.com/osmcode/mercator-projection for all the details and
+  benchmarks. You can disable this by defining the macro
+  `OSMIUM_USE_SLOW_MERCATOR_PROJECTION` before including any of the Osmium
+  headers.
+- Removed the outdated `Makefile`. Always use CMake directly to build.
+- Refactoring of `osmium::apply()` removing the resursive templates for faster
+  compile times and allowing rvalue handlers.
+- Lots of code and test cleanups and more documentation.
+
 ### Fixed
 
+- Handle endianess on FreeBSD properly.
+- Fixed doxygen config for reproducible builds.
+
