-* blosc2.evaluate: a drop-in replacement of numexpr.evaluate().  This

+We also added new ``blosc2.matmul()`` function for computing matrix
+multiplication on NDArray instances.
 
-  - More functionality than numexpr (e.g. reductions).
-  - Follow casting rules of NumPy more closely.
-  - Use both NumPy arrays and Blosc2 NDArrays in the same expression.

-* blosc2.jit: a decorator to compile a function with a NumPy expression
-  using the compute engine of Blosc2.  Useful to speed up the evaluation
-  of pure NumPy expressions at runtime.

 - Integrates with Numba and Cython via UDFs (User Defined Functions).
 - Adheres to modern NumPy casting rules way better than numexpr.
 - Computes expressions only when needed. They can also be stored for later use.

+## Changes from 3.1.1 to 3.2.0
 
 * Structured arrays can be larger than 255 bytes now.  This was a limitation
   in the previous versions, but now it is gone (the new limit is ~512 MB,
   which I hope will be enough for some time).
 
+* New `blosc2.matmul()` function for computing matrix multiplication on NDArray
+  instances.  This allows for efficient computations on compressed data that
+  can be in-memory, on-disk and in the network.  See
+  [here](https://www.blosc.org/python-blosc2/reference/autofiles/operations_with_arrays/blosc2.matmul.html)
+  for more information.
+
+* Support for building WASM32 wheels.  This is a new feature that allows to
+  build wheels for WebAssembly 32-bit platforms.  This is useful for running
+  Python code in the browser.
+
+* Tested support for NumPy<2 (at least 1.26 series).  Now, the library should
+  work with NumPy 1.26 and up.
+
+* C-Blosc2 updated to 2.17.0.
+
+* httpx has replaced by requests library for the remote proxy.  This has been
+  done to avoid the need of the `httpx` library, which is not supported by
+  Pyodide.
