+
+### Added
+ - Add `MultiFieldCellValues` as a `FEValues` object optimized for problems with multiple
+   fields. ([#872])
+ - Embedded elements now return mixed tensors
+   ([https://github.com/Ferrite-FEM/Tensors.jl/pull/236]) instead of static arrays.
+   ([#1286])
+ - `facedof_indices` and `edgedof_indices` are now generated by default. ([#1293])
+ - Widen interfaces to allow more vector types ([#1252])
+ - Assembly of rectangular matrices. ([#1279])
+
+### Fixes
+- The result of grid coloring is now not dependent on iteration order of dictionaries and
+  sets. This may change the coloring obtained from `create_coloring` compared to previous
+  Ferrite versions. ([#1295])
+
+### Performance
+ - Simplify `InterfaceIterator`. ([#1281])
+ - The default `allocate_matrix` call has been optimized using specialized code paths.
+   ([#1302])
+ - Remove redundant views in `InterfaceValues`. ([#1306])
+ - Optimize `apply!` call on constraint handler. ([#1310])
+
+### Documentation
+ - Fix typos in the tutorials. ([#865], [#1268], [#1271], [#1278], [#1298], [#1313])
+ - Replace incorrect `threadid` calls with recommended threading approach in Landau example
+   ([#1294])
+
+### CI
+ - Add typo checker to CI. ([#865])
+ - Add changelog check to CI. ([#1321])
+ - Update actions. ([#1314], [#1315])
