+Increased minimum versions for dependencies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Some minimum supported versions of dependencies were updated (:issue:`29723`).
+If installed, we now require:
+
++-----------------+-----------------+----------+
+| Package         | Minimum Version | Required |
++=================+=================+==========+
+| numpy           | 1.13.3          |    X     |

++-----------------+-----------------+----------+
+
+For `optional libraries <https://dev.pandas.io/docs/install.html#dependencies>`_ the general recommendation is to use the latest version.
+The following table lists the lowest version per library that is currently being tested throughout the development of pandas.
+Optional libraries below the lowest tested version may still work, but are not considered supported.
