When Levenshtein-based suggestions find no match for an AttributeError
on list, str, or dict, check a static table of common method names from
JavaScript, Java, C#, and Ruby.
For example, [].push() now suggests .append(), "".toUpperCase() suggests
.upper(), and {}.keySet() suggests .keys().
The list.add() case suggests using a set instead of suggesting .append(),
since .add() is a set method and the user may have passed a list where
a set was expected (per discussion with Serhiy Storchaka, Terry Reedy,
and Paul Moore).
Design: flat (type, attr) -> suggestion text table, no runtime
introspection. Only exact builtin types are matched to avoid false
positives on subclasses.

* empty lines are always ignored instead of separating groups
* the "user-agent" line after a rule starts a new group
* groups matching the same user agent are now merged
* the rule with the longest match wins instead of the first matching rule
* in case of equal matches, the “Allow” rule wins over “Disallow”
* special characters “$” and “*” are now supported in rules
* prefer full match for user agent

* Add Zd/Zf format support to array, memoryview and struct.
* ctypes: Replace F/D/G complex format with Zf/Zd/Zg.
* Modify array, ctypes and struct modules to support format strings
longer than 1 character (such as "Zd").
* Change array.typecodes type from str to tuple.
* Handle non-source modules more gracefully (and consistently)
* Improve handling of frozen modules (which may or may not have source)
* Avoid reporting misleading info when looking up objects via aliases
* Refactor CLI implementation to improve testability
* Add several more test cases
Closes#149010
Avoid the phrasing ‘starting with ::FFFF/96’, which is confusing since
it seems to mix a prefix and a range. Instead, make it clear what the
actual range is, and refer to the relevant RFC.
Closes#87245.
The _SSLSocket object now remembers if it gets an EOF error. In this
case, read(), sendfile(), write() and do_handshake method calls fail
with SSLEOFError without calling the underlying OpenSSL function.

Adds `python -m profiling.sampling dump <pid>`, which prints a single
traceback-style snapshot of a running process's Python stack via the
existing `_remote_debugging` unwinder. Supports per-thread status,
source line highlighting, optional bytecode opcodes, and async-aware
task reconstruction (`--async-aware`, default `--async-mode=all`).
Support custom headers in `python -m http.server` and `http.server.SimpleHTTPRequestHandler`.

unittest.TestCase methods assertWarns() and assertWarnsRegex() no longer
swallow warnings that do not match the specified category or regex.
Nested context managers are now supported.
