== Highlights

* Switch to Jinja2 template engine for faster and more memory lenient server-side content generation (#12639)
* Modernized the code to support Python 2.7 idioms (earlier versions are no longer supported)
  (#12046, #12148, #12558, #12569)
* Removed lots of backward compatibility APIs from pre-1.0 days; 
  in particular, the database API is now exclusively based on the [[TracDev/ApiChanges/1.3#DatabaseAPIChanges|context managers]] (#9612, #11901)

== Code Name

The [milestone:0.11] release was dubbed "Genshi" and [milestone:0.12] "Babel", 
after the names of the Python packages that became closely associated to these Trac versions.
Therefore, it seems appropriate to name 1.4 "Jinja".
