== Highlights

* Jinja2 is the template engine, providing performance
  improvements over Genshi. Genshi is still supported
  until Trac 1.5.1 for rendering plugin templates.
* Custom navigation items can be added to the
  main and meta navigation (#11317).
* TracAdmin `convert_db` command for
  converting to a new database backend while
  preserving all environment data
  (#12299).
* Restyled wiki that allows toggling between
  narrow and full width (#12640).

== 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".
