+Some of you might have come across the python-weka-wrapper3 library, which makes Weka available from Python:
+
+  `https://github.com/fracpete/python-weka-wrapper3 <https://github.com/fracpete/python-weka-wrapper3>`__
+
+When the project started out, it relied on the javabridge library in order to communicate with Java Virtual Machine
+running the Weka process. Unfortunately, that project hasn't been maintained properly for a while now and it made
+installation difficult or even impossible for M1/M2 Mac (ARM) users.
+
+Over the last few weeks, I migrated the code base to using the `JPype library <https://github.com/jpype-project/jpype>`__
+and updated the documentation accordingly.
+
+Since the code-based appeared stable (tests and examples worked), I made a new release on Friday last week: **0.3.0**
+
+There are several good news: **first**, the installation is much easier; **second**, ARM Mac users can use it
+now as well; **third**, there were pretty much no interface changes necessary, as all changes happened behind
+the scenes (only low-level access to Java objects changed).
+
+So, if you had problems in the past, you might want to give it a go again.
