@itemize @bullet
+@item
+Release 7.5.12 is a complete reorganization of the source tree to use
+modern configuration techniques based on autoconf. The purpose of this
+reorganization is to simplify maintenance, porting, and the generation
+of binary packages (e.g. Debian @samp{.deb} packages). The C code has
+been extensively modified to support this, and a lot of general cleanup
+has been done. There should be no user-visible changes due to the
+reorganization, aside from the usual crop of bug fixes.
