+=================================

+The Blosc development team is pleased to announce the third release release of
+Python-Blosc2 3.0.0. Here, we are making easier to produce conda packages, as
+well as fixing some bugs and improving the documentation.
 
-The Blosc development team is pleased to announce the second release release of
-Python-Blosc2 3.0.0. Here, we are streamlining the API and adding more flexibility
-to the compute engine (e.g. support for reductions in fields of struct arrays).
 You can think of Python-Blosc2 3.0 as a replacement of numexpr, but better :-)
 
 As always, we would like to get feedback from the community before the final
 release. We are providing binary wheels that you can easily install from PyPI
 with:
 
-    pip install blosc2==3.0.0rc2
+    pip install blosc2==3.0.0rc3

-XXX version-specific blurb XXX
+* Now you can get and set the whole values of VLMeta instances with the `vlmeta[:]` syntax.
+  The get part is syntactic sugar for `vlmeta.getall()` actually.
+
+* `blosc2.copy()` now honors `cparams=` parameter.
+
+* Now, compiling the package with `USE_SYSTEM_BLOSC2` envar set to `1` will use the
+  system-wide Blosc2 library.  This is useful for creating packages that do not want
+  to bundle the Blosc2 library (e.g. conda).
+
+* Several changes in the build process to enable conda-forge packaging.
+
+* Now, `blosc2.pack_tensor()` can pack empty tensors/arrays.  Fixes #290.
