=============================
.. 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`),
-plus syntax highlighting in the REPL,

as well as the usual deprecations and removals,
and improvements in user-friendliness and correctness.
