----------
* We are rolling out a major upgrade of the SQL system where we've upgraded the database drivers and the SQL alchemy
library that underpins it. This fixes several known vulnerabilities in the library and the drivers.

Note that there is a change in behaviour in the Oracle driver which no longer pads up to ``Y`` trailing zeros in
columns of datatype ``NUMBER(X,Y)``, e.g. it will now return ``2.91`` instead of ``2.9100`` in a column of
type ``NUMBER(6,4)``. The ``sql`` source may for this reason produce updated results for existing entities.
