 ==================================
 
-The Blosc development team is pleased to announce the first release release of
-Python-Blosc2 3.0.0. In this release, we have focused on the making of a
-compute engine that can work with compressed data in a NumPy-like fashion.
+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==3.0.0rc1
+    pip install blosc2==3.0.0rc2

 ## Changes from 3.0.0-rc.1 to 3.0.0
 
-   XXX version-specific blurb XXX
+* Improved docs, tutorials and examples.  Have a look at our new docs at: https://www.blosc.org/python-blosc2.
+
+* `blosc2.save()` is using `contiguous=True` by default now.
+
+* `vlmeta[:]` is syntatic sugar for vlmeta.getall() now.
+
+* Add `NDArray.meta` property as a proxy to `NDArray.shunk.vlmeta`.
+
+* Reductions over single fields in structured NDArrays are now supported.  For example, given an array `sarr` with fields 'a', 'b' and 'c', `sarr["a"]["b >= c"].std()` returns the standard deviation of the values in field 'a' for the rows that fulfills that values in fields in 'b' are larger than values in 'c' (`b >= c` above).
+
+* As per discussion #337, the default of cparams.splitmode is now AUTO_SPLIT. See #338 though.
