I'm pleased to announce version 3.7.2, the second bugfix release of branch 3.7 of SQLObject. What's new in SQLObject ======================= Minor features -------------- * Adapt Postgres exception handling to ``psycopg2`` version ``2.8``: in the recent ``psycopg2`` errors are in ``psycopg2.errors`` module. * Removed RdbhostConnection: David Keeney and rdbhost seem to be unavailable since 2017. For a more complete list, please see the news: http://sqlobject.org/News.html What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB). Python 2.7 or 3.4+ is required.
