+  * Tests
+    + gh-140482: Preserve and restore the state of stty echo as part of the
+      test environment.
+    + gh-140082: Update python -m test to set FORCE_COLOR=1 when being run
+      with color enabled so that unittest which is run by it with redirected
+      output will output in color.
+    + gh-136442: Use exitcode 1 instead of 5 if
+      unittest.TestCase.setUpClass() raises an exception
+  * Security
+    + gh-137836: Add support of the “plaintext” element, RAWTEXT elements

+      element “noscript” in html.parser.HTMLParser.
+    + gh-136063: email.message: ensure linear complexity for legacy HTTP
+      parameters parsing. Patch by Bénédikt Tran.
+    + gh-136065: Fix quadratic complexity in os.path.expandvars().
+  * Library
+    + gh-141497: ipaddress: ensure that the methods IPv4Network.hosts() and
+      IPv6Network.hosts() always return an iterator.
+    + gh-140938: The statistics.stdev() and statistics.pstdev() functions now
+      raise a ValueError when the input contains an infinity or a NaN.
+    + gh-124111: Updated Tcl threading configuration in _tkinter to assume

+    + gh-137109: The os.fork and related forking APIs will no longer warn in
+      the common case where Linux or macOS platform APIs return the number of
+      threads in a process and find the answer to be 1 even when a
+      os.register_at_fork() after_in_parent= callback (re)starts a thread.

+      reading files with standalone carriage return (\r) line endings.
+    + gh-141311: Fix assertion failure in io.BytesIO.readinto() and undefined

+      such as compile(), ast.parse(), symtable.symtable(), and
+      importlib.abc.InspectLoader.source_to_code() now allow to specify the
+      module name. It is needed to unambiguous filter syntax warnings by
+      module name.
+    + gh-139640: ast.parse() no longer emits syntax warnings for
+      return/break/continue in finally (see PEP 765) - they are only emitted

+  * C API
+    + gh-116146: Add a new PyImport_CreateModuleFromInitfunc() C-API for
+      creating a module from a spec and initfunc. Patch by Itamar Oren.
+    + gh-141042: Make qNaN in PyFloat_Pack2() and PyFloat_Pack4(), if while

+    + gh-139653: Add PyUnstable_ThreadState_SetStackProtection() and
+      PyUnstable_ThreadState_ResetStackProtection() functions to set the
+      stack protection base address and stack protection size of a Python
+      thread state. Patch by Victor Stinner.
+  * Build
+    + gh-140454: When building the JIT, match the jit_stencils filename
+      expectations in Makefile with the generator script. This avoid needless
+      JIT recompilation during make install.
+    + gh-140768: Warn when the WASI SDK version doesn’t match what's
+      supported.
+    + gh-140513: Generate a clear compilation error when _Py_TAIL_CALL_INTERP
