 A fast, compressed and persistent binary data store library for C.
 
 ## What is new?
 
 The Blosc development team is happy to announce a new release of C-Blosc2.
-In this release, we are including new API functions and fixes for a series
-of bugs related with appends and insertions of chunks in super-chunks.
-Also important, now linking against an external zlib-ng compiled with native
-API is supported.
+In order to allow to compile with both C-Blosc and C-Blosc2 libraries,
+a new API has been created for the overlapping symbols and function names.
+Also, we have fixed the conversion between super-chunks and frames.
 
 C-Blosc2 should be backward compatible with C-Blosc, so you can start using
 it right away and increasingly start to use its new functionality, like the

 * [API change] In order to allow to compile with both C-Blosc and C-Blosc2 libraries, a new API has been created for the symbols and function names that had collisions.  Here are the changed symbols and functions:
 
   * Blosc2 symbols that take different values than in Blosc1:
+    - BLOSC_VERSION_MAJOR -> BLOSC2_VERSION_MAJOR
+    - BLOSC_VERSION_MINOR -> BLOSC2_VERSION_MINOR

-  To compile with the previous API (corresponding to C-Blosc2 pre-2.3.0), it is enough to define the `BLOSC1_COMPAT` symbol in your C-Blosc2 app.
+  It is recommended to migrate to the new API as soon as possible.  In the meanwhile, you can still compile with the previous API (corresponding to C-Blosc2 pre-2.3.0), by defining the `BLOSC1_COMPAT` symbol in your C-Blosc2 app (before including the 'blosc2.h' header).
+
+* Fixed some issues in converting from super-chunks to frames and back.  Now it is possible to do a rountrip without (known) problems.
