gh-141376: smelly.py: Print only smelly symbols, or all of them with --verbose (GH-141394)
Instead of long and uninteresting output for all checked libraries, only print found issues by default.

Add a new -v/--verbose option to list all symbols (useful for checking that the script finds the symbols).

gh-143513: Remove importlib.abc documentation for removed ABCs (#143605)
In 3.11 ResourceReader, Traversable, & TraversableResources moved from importlib.abc to importlib.resources.abc (commit e712a5b277866a71c195f38c1b5d87d9126dba3e).

In 3.12 old import locations were deprecated (commit 71848c960927af801656026203371c41ad139b5a).

In 3.14 backwards-compat support was removed (commit 0751511d24295c39fdf2f5b2255e3fa3d796ce4d).

gh-144157: Optimize bytes.translate() by deferring change detection (GH-144158)
Optimize bytes.translate() by deferring change detection

Move the equality check out of the hot loop to allow better compiler
optimization. Instead of checking each byte during translation, perform
a single memcmp at the end to determine if the input can be returned
unchanged.

This allows compilers to unroll and pipeline the loops, resulting in ~2x
throughput improvement for medium-to-large inputs (tested on an AMD zen2).
No change observed on small inputs.

It will also be faster for bytes subclasses as those do not need change
detection.

gh-67041: Allow to distinguish between empty and not defined URI components (GH-123305)
Changes in the urllib.parse module:

* Add option missing_as_none in urlparse(), urlsplit() and urldefrag(). If
  it is true, represent not defined components as None instead of an
  empty string.
* Add option keep_empty in urlunparse() and urlunsplit(). If it is
  true, keep empty non-None components in the resulting string.

gh-143993: Document ways to disable remote debugging support (#143994)
Although PEP 768 mentions how to disable the mechanism of
remote debugging, it is not documented in the Python docs.

This change adds a note on how to disable remote debugging support
in a Python interpreter to the remote debugging how-to.

gh-144054: no deferred refcount for untracked (gh-144081)
This reverts gh-144055 and fixes the bug in a different way.  Deferred
reference counting relies on the object being tracked by the GC,
otherwise the object will live until interpreter shutdown.  So, take
care that we do not enable deferred reference counting for objects that
are untracked.  Also, if a tuple has deferred reference counting
enabled, don't untrack it.

gh-144054: shutdown fix for deferred ref counting (GH-144055)
When shutting down, disable deferred refcounting for all GC objects. It
is important to do this also for untracked objects, which before this
change were getting missed.

Small code cleanup:
We can remove the shutdown case disable_deferred_refcounting() call
inside scan_heap_visitor() if we are careful about it.  The key is
that frame_disable_deferred_refcounting() might fail if the object
is untracked.

gh-143774 - Improve IDLE Format Paragraph doc (#143775)
Add a reminder to not rewrap code line to the Menu => Format => Reformat Paragraph entry.
In Editing and Nagivagion, add a new 'Format block' subsection that defines 'paragraph'
to better match what is dependably handled as more or less expected.
In particular, specify equal indents and that the resulting indent equals original indent.
Also mention that selections are expanded to complete lines and how to modify max length.

(Also fix a couple case errors in cross references.)

This change ensures the internal buffered lock is always released
on error, keeping the object in a consistent state after failures.

gh-143935: Email preserve parens when folding comments (#143936)
Fix a bug in the folding of comments when flattening an email message
using a modern email policy. Comments consisting of a very long sequence of
non-foldable characters could trigger a forced line wrap that omitted the
required leading space on the continuation line, causing the remainder of
the comment to be interpreted as a new header field. This enabled header
injection with carefully crafted inputs.
