 ## [Unreleased]
 
+## v0.2.1
+
+Major update with many new features:
+- Elastic, dielectric, and piezoelectric tensors are now supported.
+- Wave function coefficients are now desymmetrised on the fly, meaning 
+  `wavefunction.h5` files are much smaller.
+- New tool to extract wave function coefficients that removes the `pawpyseed`  and is 
+  much faster. This is a python only implementation and doesn't require compiling any 
+  additional codes.
+- Mesh properties (scattering rates etc, energies, velocities) stored in a separate 
+  mesh.h5 file which is much smaller and faster to read.
+- Revamped unit tests.
