+2.5.10.2
+--------
+* (The patch `_p` version notation used in 2.5.10_p1 is not widely supported so
+  this release simply uses the dot notation.)
+* Removes Python module (moved to separate repository at
+  https://github.com/jonls/python-qsoptex).
+* Move library source files into `qsopt_ex` so the header files can be accessed
+  in the same way as when installed (`<qsopt_ex/XX.h>`).
+* Explicitly include the typename of template types when using a macro,
+  variable or function that is template generated. This removes the
+  build dependencies on Exuberant Ctags and GNU sed, as well as speeding up
+  the template generation significantly.
+* Remove util.c/util.h from template generation since the majority of symbols
+  are not template type specific.

 2.5.10_p1
 ---------
 * Based on original version v2.5.10 published by Daniel Espinoza et al.
