- with a null byte.
+- Issue #26171: Fix possible integer overflow and heap corruption in
+ zipimporter.get_data().

+- Issue #25660: Fix TAB key behaviour in REPL with readline.
-- Issue #24802: Avoid buffer overreads when int(), float(), compile(), exec()
- and eval() are passed bytes-like objects. These objects are not
- necessarily terminated by a null byte, but the functions assumed they were.

+ more than once.
-- Issue #24402: Fix input() to prompt to the redirected stdout when
- sys.stdout.fileno() fails.

- longer formatted twice.
+- Issue #25995: os.walk() no longer uses FDs proportional to the tree depth.
-- Issue #25003: os.urandom() doesn't use getentropy() on Solaris because
- getentropy() is blocking, whereas os.urandom() should not block. getentropy()
- is supported since Solaris 11.3.
+- Issue #26117: The os.scandir() iterator now closes file descriptor not only
+ when the iteration is finished, but when it was failed with error.

- imported at startup) now uses the backslashreplace error handler.
+- Issue #25911: Restored support of bytes paths in os.walk() on Windows.
-- Issue #24891: Fix a race condition at Python startup if the file descriptor
- of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
- sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
- to None if the creation of the object failed, instead of raising an OSError
- exception. Initial patch written by Marco Paolini.

-- Issue #4395: Better testing and documentation of binary operators.
- Patch by Martin Panter.
+- Issue #25945: Fixed a crash when unpickle the functools.partial object with
+ wrong state. Fixed a leak in failed functools.partial constructor.
+ "args" and "keywords" attributes of functools.partial have now always types
+ tuple and dict correspondingly.
-- Issue #24467: Fixed possible buffer over-read in bytearray. The bytearray
- object now always allocates place for trailing null byte and it's buffer now
- is always null-terminated.
+- Issue #26202: copy.deepcopy() now correctly copies range() objects with
+ non-atomic attributes.
-- Issue #24115: Update uses of PyObject_IsTrue(), PyObject_Not(),
- PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains()
- to check for and handle errors correctly.

+ invalid pattern. Patch by Thomas Nyberg.
-- Issue #24257: Fixed system error in the comparison of faked
- types.SimpleNamespace.
+- Issue #19883: Fixed possible integer overflows in zipimport.
-- Issue #22939: Fixed integer overflow in iterator object. Patch by
- Clement Rouault.

+- Issue #24705: Fix sysconfig._parse_makefile not expanding ${} vars
+ appearing before $() vars.
-- Issue #23309: Avoid a deadlock at shutdown if a daemon thread is aborted
- while it is holding a lock to a buffered I/O object, and the main thread
- tries to use the same I/O object (typically stdout or stderr). A fatal
- error is emitted instead.

+ option if it is safe to do so.

+- Issue #22570: Add 'path' attribute to pathlib.Path objects,
+ returning the same as str(), to make it more similar to DirEntry.
+ Library code can now write getattr(p, 'path', p) to get the path as
+ a string from a Path, a DirEntry, or a plain string. This is
+ essentially a small one-off protocol.
-- Issue #23803: Fixed str.partition() and str.rpartition() when a separator
- is wider then partitioned string.
+- Issue #26012: Don't traverse into symlinks for ** pattern in
+ pathlib.Path.[r]glob().

- memory conditions.
+- Issue #25447: Copying the lru_cache() wrapper object now always works,
