 =============================
 
 .. This section singles out the most important changes in Python 3.14.
    Brevity is key.
 
-Python 3.14 will be the latest stable release of the Python
-programming language, with a mix of changes to the language, the
-implementation and the standard library.
-
-The biggest changes to the implementation include template strings (:pep:`750`),
-deferred evaluation of annotations (:pep:`649`),
-and a new type of interpreter that uses tail calls.
-
-The library changes include the addition of a new :mod:`!annotationlib` module
-for introspecting and wrapping annotations (:pep:`749`),
-a new :mod:`!compression.zstd` module for Zstandard support (:pep:`784`),

 as well as the usual deprecations and removals,
 and improvements in user-friendliness and correctness.
 
+This article doesn't attempt to provide a complete specification
+of all new features, but instead gives a convenient overview.
+For full details refer to the documentation,
+such as the :ref:`Library Reference <library-index>`
+and :ref:`Language Reference <reference-index>`.
+To understand the complete implementation and design rationale for a change,
+refer to the PEP for a particular new feature;
+but note that PEPs usually are not kept up-to-date
+once a feature has been fully implemented.
