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

From a user POV, bugfixes and new projections are not that big a deal,
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
