+=======================
+Tested Runtimes for Zed
+=======================
+
+At the start of the Zed development cycle, the current :ref:`LTS or stable
+distribution <pti-linux-distros>` versions are:
+
+* Ubuntu 20.04
+* CentOS Stream 9
+* Debian 11
+
+Python Runtimes for Zed
+=======================
+
+It is the :doc:`policy <../../resolutions/20181024-python-update-process>` that
+each OpenStack release cycle will target the latest available version of
+Python; default Python runtimes on the distributions listed above; and versions
+used in integration tests at the start of the cycle, at least until the point
+when all projects have migrated to a later version.
+
+Based on the criteria above, all Python-based projects must target and test
+against, at a minimum:
+
+* Python 3.8 (available as default in Ubuntu 20.04)
+* Python 3.9 (available as default in Debian 11 and CentOS Stream 9)
+
+More details on Python requirements can be found in :ref:`pti-python`.
+
+Node.js Runtime for Zed
+=======================
+
+Based on the available versions of Node.js supported in our :ref:`LTS or stable
+distributions <pti-linux-distros>` all JavaScript testing should target:
+
+* Node.js 16
+
+More details on Javascript requirements can be found in :ref:`pti-javascript`.
+
+Golang Runtime for Zed
+======================
+
+At this time, there are still frequent releases of Go with a wide variety of
+distribution packaged versions. Given the current state of Go support and the
+number of projects within OpenStack using Go, no formal version declaration is
+being made at this time.
+
+More details on Go requirements can be found in :ref:`pti-golang`.
