Core and Builtins
-----------------
-- Issue #14775: Fix a potential quadratic dict build-up due to the garbage
- collector repeatedly trying to untrack dicts.
-
-- Issue #14494: Fix __future__.py and its documentation to note that
- absolute imports are the default behavior in 3.0 instead of 2.7.
- Patch by Sven Marnach.
-
-- Issue #14761: Fix potential leak on an error case in the import machinery.
+- Issue #11022: open() and io.TextIOWrapper are now calling
+ locale.getpreferredencoding(False) instead of locale.getpreferredencoding()
+ in text mode if the encoding is not specified. Don't change temporary the
+ locale encoding using locale.setlocale(), use the current locale encoding
+ instead of the user preferred encoding.
-- Issue #14699: Fix calling the classmethod descriptor directly.
-
-- Issue #14433: Prevent msvcrt crash in interactive prompt when stdin
- is closed.
-
-- Issue #11603 (again): Setting __repr__ to __str__ now raises a RuntimeError
- when repr() or str() is called on such an object.
+- Issue #14673: Add Eric Snow's sys.implementation implementation.
-- Issue #14658: Fix binding a special method to a builtin implementation of a
- special method with a different name.
+Library

-- Issue #14630: Fix a memory access bug for instances of a subclass of int
- with value 0.
++- Issue #15036: Allow removing or changing multiple items in
++ single-file mailboxes (mbox, MMDF, Babyl) flushing the mailbox
++ between the changes.
+
-- Issue #14612: Fix jumping around with blocks by setting f_lineno.
+- Issue #14059: Implement multiprocessing.Barrier.
-- Issue #14607: Fix keyword-only arguments which started with ``__``.
+- Issue #15061: The inappropriately named hmac.secure_compare has been
+ renamed to hmac.compare_digest, restricted to operating on bytes inputs
+ only and had its documentation updated to more accurately reflect both its
+ intent and its limitations
-- Issue #13889: Check and (if necessary) set FPU control word before calling
- any of the dtoa.c string <-> float conversion functions, on MSVC builds of
- Python. This fixes issues when embedding Python in a Delphi app.
+- Issue #13841: Make child processes exit using sys.exit() on Windows.
-- Issue #14474: Save and restore exception state in thread.start_new_thread()
- while writing error message if the thread leaves a unhandled exception.
+- Issue #14936: curses_panel was converted to PEP 3121 and PEP 384 API.
+ Patch by Robin Schreiber.
-- Issue #13019: Fix potential reference leaks in bytearray.extend(). Patch
- by Suman Saha.
+- Issue #1667546: On platforms supporting tm_zone and tm_gmtoff fields
+ in struct tm, time.struct_time objects returned by time.gmtime(),
+ time.localtime() and time.strptime() functions now have tm_zone and
+ tm_gmtoff attributes. Original patch by Paul Boddie.
-- Issue #14378: Fix compiling ast.ImportFrom nodes with a "__future__" string as
- the module name that was not interned.
+- Rename adjusted attribute to adjustable in time.get_clock_info() result.
-- Issue #14331: Use significantly less stack space when importing modules by
- allocating path buffers on the heap instead of the stack.
+- Issue #3518: Remove references to non-existent BaseManager.from_address()
+ method.
-- Issue #14334: Prevent in a segfault in type.__getattribute__ when it was not
- passed strings.
+- Issue #13857: Added textwrap.indent() function (initial patch by Ezra
+ Berch)
-- Issue #1469629: Allow cycles through an object's __dict__ slot to be
- collected. (For example if ``x.__dict__ is x``).
+- Issue #2736: Added datetime.timestamp() method.
-- Issue #14172: Fix reference leak when marshalling a buffer-like object
- (other than a bytes object).
+- Issue #13854: Make multiprocessing properly handle non-integer
+ non-string argument to SystemExit.
-- Issue #13521: dict.setdefault() now does only one lookup for the given key,
- making it "atomic" for many purposes. Patch by Filip Gruszczyński.
+- Issue #12157: Make pool.map() empty iterables correctly. Initial
+ patch by mouad.
-- Issue #14471: Fix a possible buffer overrun in the winreg module.

+- Issue #14711: os.stat_float_times() has been deprecated.
-- Issue #15036: Allow removing or changing multiple items in
- single-file mailboxes (mbox, MMDF, Babyl) flushing the mailbox
- between the changes.
+- LZMAFile now accepts the modes "rb"/"wb"/"ab" as synonyms of "r"/"w"/"a".
-- Issue #10133: Make multiprocessing deallocate buffer if socket read
- fails. Patch by Hallvard B Furuseth.
+- The bz2 and lzma modules now each contain an open() function, allowing
+ compressed files to readily be opened in text mode as well as binary mode.
-- Issue #13854: Make multiprocessing properly handle non-integer
- non-string argument to SystemExit.
+- BZ2File.__init__() and LZMAFile.__init__() now accept a file object as their
+ first argument, rather than requiring a separate "fileobj" argument.
-- Issue #12157: Make pool.map() empty iterables correctly. Initial
- patch by mouad.
+- gzip.open() now accepts file objects as well as filenames.
- Issue #14992: os.makedirs(path, exist_ok=True) would raise an OSError
when the path existed and had the S_ISGID mode bit set when it was
