+Announcing Caterva2 2025.8.7
 =============================
 
 Caterva2 is a high-performance storage and computation system for
 Blosc2 data repositories.
 
-This is a major release that includes native support for HDF5 datasets.
-Also, the tomography viewer has been improved to support navigation
-across different axes, not just the first one.  In addition, we have
-added new `concatenate` and `stack` API methods to mirror new Blosc2
-capabilities.
+This is a major release that includes a big refactoring for getting rid of
+the PubSub code (which, to be frank, was not bringing too much benefit).
+We have added a new `cat2agent` to watch a directory and sync changes to a
+Caterva2 server.
+
+Finally, fixed a few bugs and added some new features, such as the
+`cat2agent` command line client, which allows you to watch a directory and
+sync changes to a Caterva2 server. This is particularly useful for
+automatically uploading new datasets to a Caterva2 server, or for keeping
+a local copy of a remote Caterva2 server.

 ## What is it?
 
-Caterva2 is a distributed system written in Python meant for sharing Blosc2
-datasets among different hosts by using a publish–subscribe messaging pattern
-(see https://en.wikipedia.org/wiki/Publish–subscribe_pattern).  Here,
-publishers categorize datasets into root groups that are announced to the
-broker and propagated to subscribers.
-
-Subscribers can access datasets of publishers on demand on behalf of clients,
-and cache them locally. This could be particularly useful for accessing remote
-datasets and sharing them within a local network, thereby optimizing
-communication and storage resources within work groups.
+Caterva2 is a server written in Python meant for sharing Blosc2 and HDF5
+datasets.  There are several interfaces to Caterva2, including a web GUI,
+a REST API, a Python API, and a command-line client. With Caterva2, you can
+easily share your datasets with your colleagues, or even the public.
 
 Caterva2 is distributed using the AGPL license, see
 https://github.com/ironArray/Caterva2/blob/main/LICENSE.txt
 for details.

 # Release notes
 
+## Changes from 2025.6.26 to 2025.8.7
+
+### Big refactoring
+
+* The PubSub code has been pruned. Even if powerful, PubSub added much
+  complexity to the code, without providing a clear benefit.
+
+* New `cat2agent` to watch a directory and sync changes to a Caterva2 server.
+  This is particularly useful for automatically uploading new datasets to a
+  Caterva2 server, or for keeping a local copy of a remote Caterva2 server.
+
+* With the introduction of the HDF5Proxy class, HDF5Root was obsoleted and
+  has been removed.
+
+### Web frontend
+
+* New stack/concat prompt commands.
+
+### API changes
+
+* No API changes for the client REST or Python APIs, so the big refactoring
+  does not affect them.
+
+### Bug fixes and improvements
+
+* Fix "/api/chunk/{path:path}" for shared/public.
+
+* Several minor fixes so that the behavior of the server is more consistent.
+
 ## Changes from 2025.5.2 to 2025.6.26
 
 ### New support for native HDF5 files
