+*******************
+Version information
+*******************
+
+The ``numpy.version`` submodule includes several constants that expose more
+detailed information about the exact version of the installed ``numpy``
+package:
+
+.. data:: version
+
+    Version string for the installed package - matches ``numpy.__version__``.
+
+.. data:: full_version
+
+    Version string - the same as ``numpy.version.version``.
+
+.. data:: short_version
+
+    Version string without any local build identifiers.
+
+    .. rubric:: Examples
+
+    >>> np.__version__
+    '2.1.0.dev0+git20240319.2ea7ce0'  # may vary
+    >>> np.version.short_version
+    '2.1.0.dev0'
+
+.. data:: git_revision
+
+    String containing the git hash of the commit from which ``numpy`` was built.
+
+.. data:: release
+
+    ``True`` if this version is a ``numpy`` release, ``False`` if a dev version.
