The main feature of this release is native JSON data type support in databases. We have added a new chapter to the documentation, which describes how it works.

Here is the list of changes, improvements and bug fixes:

• Starting with this release Pony drops Python 2.6 support
• Added an experimental @db_session strict parameter
• Merged #179: Added the compatibility with PYPY using psycopg2cffi
• Fixed #182 – LEFT JOIN doesn’t work as expected for inherited entities when foreign key is None
• Fixed some small bugs

To install the updated version use the following command:

pip install --upgrade pony
