This is the initial beta release in the 1.3 series of SQLAlchemy, the latest iteration of new features and behavioral improvements. Highlights of 1.3 include:

• Performance improvements to the new "select in" loader strategy, such that a JOIN is no longer used at all to load collections
• JSON support for SQLite
• Support for SQLite's "ON CONFLICT" constraint directive
• Improvements to the new "expanding" bound parameter used for "IN" expressions, such that empty "IN" expressions are now supported
• new schema naming convention features and support for automatic truncation of long names
• a series of architectural and API improvements to the association proxy extension
• architectural and behavioral improvements to the Query.join() method
• Improvements to rendering and reflection of FULLTEXT indexes on MySQL
• Support for pyodbc's "fast executemany" mode for SQL Server
• Architectural improvements and updates to the cx_oracle dialect to keep up with the high velocity of changes being made to this DBAPI upstream

Release 1.3 includes approximately 39 individual improvements and features.
