+New ``make regen-all`` build target
+-----------------------------------
+
+To simplify cross-compilation, and to ensure that CPython can reliably be
+compiled without requiring an existing version of Python to already be
+available, the autotools-based build system no longer attempts to implicitly
+recompile generated files based on file modification times.
+
+Instead, a new ``make regen-all`` command has been added to force regeneration
+of these files when desired (e.g. after an initial version of Python has
+already been built based on the pregenerated versions).
+
+More selective regeneration targets are also defined - see
+:source:`Makefile.pre.in` for details.

+Removal of ``make touch`` build target
+--------------------------------------
+
+The ``make touch`` build target previously used to request implicit regeneration
+of generated files by updating their modification times has been removed.
+
+It has been replaced by the new ``make regen-all`` target.
