+* The 'configure' options '--{en,dis}able-groff-allocator' introduced
+ in groff 1.23.0 are now deprecated. `--disable-groff-allocator` has
+ been implicit since that release, and we've received no reports of a
+ C++ runtime unable to handle groff's demands on its heap/"free store"
+ allocator. We expect to withdraw these configuration options
+ completely in groff 1.26.
