 :file:`MANIFEST`, you must specify everything: the default set of files
 described above does not apply in this case.
 
-.. versionadded:: 2.7
+.. versionchanged:: 2.7
+   An existing generated :file:`MANIFEST` will be regenerated without
+   :command:`sdist` comparing its modification time to the one of
+   :file:`MANIFEST.in` or :file:`setup.py`.
+
+.. versionchanged:: 2.7.1
    :file:`MANIFEST` files start with a comment indicating they are generated.
    Files without this comment are not overwritten or removed.
 
+.. versionchanged:: 2.7.3
+   :command:`sdist` will read a :file:`MANIFEST` file if no :file:`MANIFEST.in`
+   exists, like it did before 2.7.
+
 See :ref:`manifest_template` section for a syntax reference.
 
+
 .. _manifest-options:
 
 Manifest-related options
 
 The normal course of operations for the :command:`sdist` command is as follows:
 
-* if the manifest file, :file:`MANIFEST` doesn't exist, read :file:`MANIFEST.in`
-  and create the manifest
+* if the manifest file (:file:`MANIFEST` by default) exists and the first line
+  does not have a comment indicating it is generated from :file:`MANIFEST.in`,
+  then it is used as is, unaltered
+
+* if the manifest file doesn't exist or has been previously automatically
+  generated, read :file:`MANIFEST.in` and create the manifest
 
 * if neither :file:`MANIFEST` nor :file:`MANIFEST.in` exist, create a manifest
   with just the default file set
 
-* if either :file:`MANIFEST.in` or the setup script (:file:`setup.py`) are more
-  recent than :file:`MANIFEST`, recreate :file:`MANIFEST` by reading
-  :file:`MANIFEST.in`
-
 * use the list of files now in :file:`MANIFEST` (either just generated or read
   in) to create the source distribution archive(s)
 
 ``a-z``, ``a-zA-Z``, ``a-f0-9_.``).  The definition of "regular filename
 character" is platform-specific: on Unix it is anything except slash; on Windows
 anything except backslash or colon.
-
-.. versionchanged:: 2.7
-    An existing generated :file:`MANIFEST` will be regenerated without
-    :command:`sdist` comparing its modification time to the one of
-    :file:`MANIFEST.in` or :file:`setup.py`.
