 The [latest SQL standard](https://www.iso.org/standard/63556.html) is **not
 free** and the licence does not allow all or parts of it to be published. Older
 versions are either out of licence, or they don't mind, here is the

 Progress
 ========
 
-There are some key milestones that I would like to hit (represented as
-versions):
-
-* `0.1.0` - Implement all mandatory features (fairly crudly) and be able to
-  run it against SQLite3. This is very close to complete, you can see the
-  [report here](http://htmlpreview.github.io/?https://github.com/elliotchance/sqltest/blob/master/report.html).
-
-* `0.2.0` - Add docker containers for various version of PostgreSQL and cleanup
-  any tests in the process.
-
-I don't want to plan too far ahead, but I imagine by that point it should be
-fairly easy to start adding more docker containers for other databases and
-produce a big comparison chart.
+Almost all of the mandatory features of the 2016 SQL standard have had tests
+written for it, but there is a lot more work to be done.
