The data model section of the language reference was written well
before the zero-argument form of super() was added.

To avoid giving the impression that they're doing something
unusual, this updates the description of `__new__` and `__init__`
to use the zero-argument form.

Patch by Cheryl Sabella.

`re.compile(..., re.DEBUG)` now displays the compiled bytecode in
human readable form.

This increased the performance of matching some patterns up to 25 times.

rather than `format(str(self), '')`.

* add a comment about why we need to increase trash_delete_nesting
* move increase and decrese outside of the loop

Using a response file will eliminate the headache associated with batch argument/quote processing.

For example I unsucessfully compiled python with visualcpptools when specifying VSInstallDir in the batch file (cannot find vcruntime.h)

```batch
build.bat -p x64 -e -M --no-tkinter  "/p:VCInstallDir=%VCInstallDir%"
```

but it build successfully when specifying it in a response file

msbuild.rsp:
```
/p:VCInstallDir=%VCInstallDir%
```

Indented parts of the Handler class documentation for improved presentation, analogous to a recent similar change for the Logger class.

when there are no more `await` or `yield (from)` before return in coroutine,
cancel was ignored.

example:

    async def coro():
        asyncio.Task.current_task().cancel()
        return 42
    ...
    res = await coro()  # should raise CancelledError

* Add Misc/NEWS and Misc/ACKS entries

Now allowed several subsequential inline modifiers at the start of the
pattern (e.g. '(?i)(?s)...').  In verbose mode whitespaces and comments
now are allowed before and between inline modifiers (e.g.
'(?x) (?i) (?s)...').

Rewrite sigwaitinfo() and sigtimedwait() unit tests for EINTR using
pthread_sigmask() to fix a race condition between the child and the
parent process.

Remove the pipe which was used as a weak workaround against the race
condition.

sigtimedwait() is now tested with a child process sending a signal
instead of testing the timeout feature which is more unstable
(especially regarding to clock resolution depending on the platform).

Custom msbuild properties passed as command line need to be passed too when calling `Build` when doing PGO build.

of regular expressions.

a submodule to a name are now supported.

compiled out-of-tree (builddir != srcdir). (see also bpo-15366)

If the child process exited with a non-zero code, don't strip the
last line of stdout anymore.

Add also a sanity check in accumulate_result().

When decoding a 4-byte GB18030 sequence, the first and third byte cannot exceed 0xFE.

Thanks to Jelle Zijlstra for the patch.

* bpo-29243: Fix Makefile with respect to --enable-optimizations

When using the Profile Guided Optimization (./configure --enable-optimizations)
Python is built not only during `make` but rebuilt again during `make test`,
`make install` and others. This patch fixes the issue.

Note that this fix produces no change at all in the Makefile if configure is
run witout --enable-optimizations.
