* New features and cleanups
- *
- *
+ * Implement PyModule_New,
+ * Fix for multiple inheritance in app-level for C-API defined classes
+ * Revert a change that removed tp_getattr (Part of the 5.7.1 bugfix release)
+ * Document more differences with CPython here_
+ * Add native PyPy support to profile frames in vmprof
+ * Fix an issue with Exception order on failed import
+ * Fix for a corner case of __future__ imports
* Bug Fixes
- *
- *
+ * Correctly handle dict.pop where the popping key is not the same type as the
+ dict's and pop is called with a default (Part of the 5.7.1 bugfix release)
+ * Improve our file's universal newline .readline implementation for
+ ``\n``, ``\r`` confusion
* Performance improvements:
- *
- *
+ * Tweaks made to improve performance by reducing the number of guards
+ inserted in jitted code, based on feedback from users
+ * Add garbage collector memory pressure to some c-level allocations
* RPython improvements
- *
- *
+ * Improve the default shadowstack garbage collector, fixing a crash with
+ multithreaded code and other issues
+ * Make sure lstrip consumes the entire string
+ * Support posix_fallocate and posix_fadvise, expose them on PyPy3.5
+ * Test and fix for int_and() propagating wrong bounds
+ * Improve the generated machine code by tracking the (constant) value of
+ r11 across intructions. This lets us avoid reloading r11 with another
+ (apparently slowish) "movabs" instruction, replacing it with either
+ nothing or a cheaper variant.
+ * Performance tweaks in the x86 JIT-generated machine code: rarely taken
+ blocks are moved off-line. Also, the temporary register used to contain
+ large constants is reused across instructions. This helps CPUs branch
+ predictor

Highlights of the PyPy3.5 release (since 5.7 beta released March 2017)
======================================================================
* New features
- *
- *
+ * Implement main part of PEP 489 (multi-phase extension module
initialization)
+ * Add docstrings to various modules and functions
* Bug Fixes
- *
- *
+ * Fix inconsistencies in the xml.etree.ElementTree.Element class, which on
+ CPython is hidden by the C version from '_elementree'.
+ * OSError(None,None) is different from OSError()
+ * Get closer to supporting 32 bit windows, translation now succeeds and most
+ lib-python/3/test runs
* Performance improvements:
- *
+ * Use "<python> -m test" to run the CPython test suite, as documented by
CPython,
+ instead of our outdated regrverbose.py script
+ * Change _cffi_src/openssl/callbacks.py to stop relying on the CPython C API.
* The following features of Python 3.5 are not implemented yet in PyPy:
* PEP 442: Safe object finalization
- * PEP 489: Multi-phase extension module initialization
