+Announcing Python-Blosc2 3.7.0
 ==============================
 
 In this release:
 
-✅ Blosc2 now suppports fancy indexing (and orthogonal indexing)
-✅ Added fast path for 1D fancy indexing
-✅ More complex slicing is now supported for lazy expressions
-✅ Blosc2 indexing more consistent with NumPy
-✅ Comprehensive ``squeeze`` function which squeezes only specified dimensions
-✅ Correctly point to most recent C-blosc2 version 2.19.1
-
-We have blogged about the new fancy indexing support:
-https://www.blosc.org/posts/blosc2-fancy-indexing/
+✅ Overhaul of documentation (API reference and Tutorials)
+✅ Improvements to lazy expression indexing and in particular much more efficient
+memory usage when applying non-unit steps
+✅ Extended functionality of ``expand_dims`` to match that of NumPy
+✅ 3(!) new data storage classes (``EmbedStore``, ``DictStore`` and ``TreeStore``)
+which allow for the efficient storage of heterogeneous array data
+
+See [here](https://github.com/Blosc/python-blosc2/pull/451#issuecomment-3178828765)
+for plots for the new data storage classes. And
+[here](https://github.com/Blosc/python-blosc2/pull/446#issuecomment-3167060686) for the improved performance
+of lazy expression slicing.
 
 You can think of Python-Blosc2 3.x as an extension of NumPy/numexpr that:

+## Changes from 3.6.1 to 3.7.0
+
+* Overhaul of documentation (API reference and Tutorials)
+
+* Improvements to lazy expression indexing and in particular much more efficient memory usage when applying non-unit steps (PR #446).
+
+* Extended functionality of ``expand_dims`` to match that of NumPy (note that this breaks the previous API) (PR #453).
+
+* The biggest change is in the form of three new data storage classes (``EmbedStore``, ``DictStore`` and ``TreeStore``) which allow for the efficient storage of heterogeneous array data (PR #451). ``EmbedStore`` is essentially an ``SChunk`` wrapper which can be stored on-disk or in-memory; ``DictStore`` allows for mixed storage across memory, disk or indeed remote; and ``TreeStore`` is a hieracrhically-formatted version of ``DictStore`` which mimics the HDF5 file format. Write, access and storage performance are all very competitive with other packages - see [plots here](https://github.com/Blosc/python-blosc2/pull/451#issuecomment-3178828765).

 ## Changes from 3.6.0 to 3.6.1
 
 * C-Blosc2 internal library updated to latest 2.19.1.
