The runtime self tests are completely new to this release, so the following is more accurate I think:

 o New (optional) runtime self tests added to proj

It's too late, but adding NEWS on trunk would be great.

since they don't in theroy change anything that was already right.

Changing UTM to etmerc is a more significant change.  (Not objecting in
the least; it's just quite notable.)   So I think we have:


4.9.3 Release Notes
-------------------

 o UTM now uses etmerc, following NGA recommendations.  Tests adjusted
   for tiny changes in values.

 o new projections: Times, Natural Earth II, Compact Miller, Patterson
   Cylindrical, and inverse for Hammer and Eckert-Greifendorff.

 o runtime self tests are now opt-in instead of opt-out

 o math constants moved to projects.h

 o bugfixes
