+Hyperspy 1.6.4 (2021-07-08)
+===========================
+
+Bug Fixes
+---------
+
+- Fix parsing EELS aperture label with unexpected value, for example 'Imaging' instead of '5 mm' (`#2772 <https://github.com/hyperspy/hyperspy/issues/2772>`_)
+- Lazy datasets can now be saved out as blockfiles (blo) (`#2774 <https://github.com/hyperspy/hyperspy/issues/2774>`_)
+- ComplexSignals can now be rebinned without error (`#2789 <https://github.com/hyperspy/hyperspy/issues/2789>`_)
+- Method `estimate_parameters` in `Polynomial` component now supports order
+  greater than 10 (`#2790 <https://github.com/hyperspy/hyperspy/issues/2790>`_)
+- Update minimal requirement of dependency importlib_metadata from
+  >= 1.6.0 to >= 3.6 (`#2793 <https://github.com/hyperspy/hyperspy/issues/2793>`_)
+
+
+Enhancements
+------------
+
+- When saving a dataset with a dtype other than
+  `uint8 <https://numpy.org/doc/stable/user/basics.types.html>`_ to a blockfile
+  (blo) it is now possible to provide the argument ``intensity_scaling`` to map
+  the intensity values to the reduced range (`#2774 <https://github.com/hyperspy/hyperspy/issues/2774>`_)
+
+
+Maintenance
+-----------
+
+- Fix image comparison failure with numpy 1.21.0 (`#2774 <https://github.com/hyperspy/hyperspy/issues/2774>`_)
+
+
