These include:
- bpo-32726: Provide an additional, more modern macOS installer variant that
supports macOS 10.9+ systems in 64-bit mode only. Upgrade the supplied
third-party libraries to OpenSSL 1.0.2n and SQLite 3.22.0. The 10.9+
installer now supplies its own private copy of Tcl/Tk 8.6.8.
- bpo-24414: Default macOS deployment target is now set by ``configure`` to
the build system's OS version (as is done by Python 3), not ``10.4``;
override with, for example, ``./configure MACOSX_DEPLOYMENT_TARGET=10.4``.
- bpo-19019: All 2.7 macOS installer variants now supply their own version
of ``OpenSSL 1.0.2``; the Apple-supplied SSL libraries and root
certificates are not longer used. The ``Installer Certificate`` command
in ``/Applications/Python 2.7`` may be used to download and install a
default set of root certificates from the third-party ``certifi`` package.
- bpo-11485: python.org macOS Pythons no longer supply a default SDK value
(e.g. ``-isysroot /``) or specific compiler version default (e.g.
``gcc-4.2``) when building extension modules. Use ``CC``, ``SDKROOT``,
and ``DEVELOPER_DIR`` environment variables to override compilers or to
use an SDK. See Apple's ``xcrun`` man page for more info.
- prepare for pending Apple removal of 32-bit support in future macOS release
glibc is deprecating libcrypt in favor of libxcrypt, however python assumes
that crypt.h will always be included. This change makes the header inclusion
explicit when libxcrypt is present on the system.
(cherry picked from commit e768c86ef4)
Modify the code to use ncurses is_pad() instead of checking WINDOW
_flags field. If your platform does not provide the is_pad(), the
existing way that checks the field will be enabled.
Note: This change does not drop support for platforms where do not
have both WINDOW _flags field and is_pad().
(cherry picked from commit 8bc7d63560)
Include sys/sysmacros.h for major(), minor(), and makedev(). GNU C libray
plans to remove the functions from sys/types.h.

Don't rebuild generated files based on file modification time
anymore, the action is now explicit. Replace "make touch"
with "make regen-all".
Changes:
* Remove "make touch", Tools/hg/hgtouch.py and .hgtouch
* Add a new "make regen-all" command to rebuild all generated files
* Add subcommands to only generate specific files:
- regen-ast: Include/Python-ast.h and Python/Python-ast.c
- regen-grammar: Include/graminit.h and Python/graminit.c
- regen-opcode-targets: Python/opcode_targets.h
* Add PYTHON_FOR_REGEN variable
* pgen is now only built by by "make regen-grammar"
* Add $(srcdir)/ prefix to paths to source files to handle correctly
compilation outside the source directory
Based on commit 5c4b0d063a by Ned
Deily, which is based on original patches by Brett Cannon and Steve
Dower.
Remove also the private _Py_svnversion() function and SVNVERSION
variable.
Note: Py_SubversionRevision() and Py_SubversionShortBranch() are
unchanged, they are part of the public API.
Backport enhancements from master, commits:
* 9c4bfa6669e220efdd379b9f8e7db32bb4e25e72: "make tags": remove -t
option of ctags. The option was kept for backward compatibility,
but it was completly removed recently. Patch written by Stéphane
Wirtel.
* cf0ac6a71ae51249a05521f49c1a0fabbb948488: Fix "make tags": set
locale to C to call sort
* 8a543c0bc7347d5b333f334d157bf4a7cd33c14a: `make tags` fixes (GH-717)
The presence of the ``--enable-optimizations`` flag is indicated by the
value of ``$enableval``, but the configure script was checking ``$withval``,
resulting in the ``--enable-optimizations`` flag being effectively ignored.
(cherry picked from commit 8cea5929f5)
Too many build tool chains do not properly support it, including building
and linking an executable fine that simply segfaults when you try to run
it (such as debian jessie 8.5's gcc 4.9). On others where it does appear
to build (ubuntu 16.04's gcc 5.4) there are still test_distutils and test_gdb
failures to deal with.
We're not going to spend time attempting to maintain a complicated white list
of what does and doesn't work in our configure.ac file.
required for PGO linking - to be a configure time error rather than
make time when --with-optimizations is enabled. Also improve our
ability to find the llvm-profdata tool on MacOS and some Linuxes.
The dependendency on the $(PGEN) variable must only be
set when not cross-compiling. When cross-compiling,
$(PGEN) will not be used, so no need to build it.
Patch by Thomas Perl.
enable link time optimizations at build time during a make profile-opt.
Some compilers and toolchains are known to not produce stable code when
using LTO, be sure to test things thoroughly before relying on it.
It can provide a few % speed up over profile-opt alone.
The backport of ensurepip to 2.7.9 allows pip to optionally be installed
or upgraded using the bundled pip provided by the new ensurepip module.
The option can be specified persistently using the configure option:
./configure --with-ensurepip[=upgrade|install|no]
It can also be overridden on either the "install" or "altinstall" targets:
make [alt]install ENSUREPIP=[upgrade|install|no]
For Python 2, the default option is "no" (do not install pip).
python --generate-posix-vars in pybuilddir.txt build target by ensuring
that pybuilddir.txt is always regenerated when configure is run and
that the newly built skeleton python does not inadvertently import
modules from previously installed instances.
when building _tkinter. configure has two new options; if used, both must
be specified:
./configure \
--with-tcltk-includes="-I/opt/local/include" \
--with-tcltk-libs="-L/opt/local/lib -ltcl8.5 -ltk8.5"
In addition, the options can be overridden with make:
make \
TCLTK_INCLUDES="-I/opt/local/include" \
TCLTK_LIBS="-L/opt/local/lib -ltcl8.6 -ltk8.6"
