Cython compiler 0.28 released
by Stefan Behnel 13 Mar '18

13 Mar '18

Hi everyone, I'm pleased to announce the immediate availability of Cython 0.28, after almost half a year of development. https://pypi.python.org/pypi/Cython/0.28 What is Cython? Cython is a widely used and production proven optimising static compiler for both the Python programming language and the extended Cython programming language, and one of the pillars of the high-performance Python ecosystem. It provides direct access to C/C++ libraries and data types as a language feature, and makes writing fast native C extensions for Python as easy as Python itself. The major new features in 0.28 include: * Cdef classes can now multiply inherit from ordinary Python classes, as long as (exactly) one base class is an extension type. * The "const" modifier can be applied to memoryview declarations to allow read-only buffers as input. * C code in the docstring of a "cdef extern" block is copied verbatimly into the generated file. The changelog lists the various other big and small features, optimisations and bug fixes that went into this release: https://github.com/cython/cython/blob/0.28/CHANGES.rst Have fun, Stefan

NumPy 1.14.2 released
by Charles R Harris 12 Mar '18

12 Mar '18

Hi All, I am pleased to announce the release of NumPy 1.14.2. This is a bugfix release for some bugs reported following the 1.14.1 release. The major problems dealt with are as follows. - Residual bugs in the new array printing functionality. - Regression resulting in a relocation problem with shared library. - Improved PyPy compatibility. This release supports Python 2.7 and 3.4 - 3.6. Wheels for the release are available on PyPI. Source tarballs, zipfiles, release notes, and the changelog are available on github <https://github.com/numpy/numpy/releases/tag/v1.14.2>. The Python 3.6 wheels available from PIP are built with Python 3.6.2 and should be compatible with all previous versions of Python 3.6. The source releases were cythonized with Cython 0.26.1, which is known to *not* support the upcoming Python 3.7 release. People who wish to run Python 3.7 should check out the NumPy repo and try building with the, as yet, unreleased master branch of Cython. Contributors ============ A total of 4 people contributed to this release. People with a "+" by their names contributed a patch for the first time. * Allan Haldane * Charles Harris * Eric Wieser * Pauli Virtanen Pull requests merged ==================== A total of 5 pull requests were merged for this release. * `#10674 <https://github.com/numpy/numpy/pull/10674>`__: BUG: Further back-compat fix for subclassed array repr * `#10725 <https://github.com/numpy/numpy/pull/10725>`__: BUG: dragon4 fractional output mode adds too many trailing zeros * `#10726 <https://github.com/numpy/numpy/pull/10726>`__: BUG: Fix f2py generated code to work on PyPy * `#10727 <https://github.com/numpy/numpy/pull/10727>`__: BUG: Fix missing NPY_VISIBILITY_HIDDEN on npy_longdouble_to_PyLong * `#10729 <https://github.com/numpy/numpy/pull/10729>`__: DOC: Create 1.14.2 notes and changelog.

G'day. pygameweb <https://github.com/pygame/pygameweb> is the source code for the pygame website <https://www.pygame.org/> at https://www.pygame.org/ [image: 6954251406_95ebe75f55_m] <https://user-images.githubusercontent.com/9541/37150001-64f351b0-22d0-11e8-…> - #52 <https://github.com/pygame/pygameweb/pull/52> Adding ability to deploy through travisci. And docs. - #46 <https://github.com/pygame/pygameweb/pull/46> Wiki readability. Wiki tools on left out of reading line. - Twitter card for releases. For nicer view when posting to twitter. - Wiki table of contents improvements. - builds docs for pygame, when something lands on pygame github master branch. - project release feeds bugfix. - Only show one recent release for each project. Some projects release a few times in a row. - Wiki, nicer pre code handling. - Wiki code uses inline colors, so copy/paste works with colors too. - use https for login and register buttons, even when on http (see Why can't we turn off HTTPS? <http://renesd.blogspot.de/2018/02/why-cant-we-turn-off-http.html>). - Ask more bad robot web crawlers not to be bad.

EuroPython 2018: Hotel tips and general update
by M.-A. Lemburg 08 Mar '18

08 Mar '18

As you may know, the Edinburgh Fringe Festival is starting one week after EuroPython 2018 in Edinburgh. Since this typically attracts many thousands of people and artists, the hotels are filling up quickly in Edinburgh. If you’re planning to attend EuroPython, please book your hotel early. Many booking sites offer free cancellations, so there’s no risk in making reservations now, even if you decide not to come in the end. Room allocation for EuroPython 2018 ----------------------------------- To help with this, we have partnered with the Edinburgh Convention Bureau to set aside a number of hotel rooms which are reserved for EuroPython attendees. These rooms will be held reserved until a few weeks before the conference and are also available with a free cancellation option. The Edinburgh Convention Bureau has setup the following website for booking rooms from this allocation: * EuroPython 2018 Hotel Booking Website * https://cabsedinburgh.eventsair.com/QuickEventWebsitePortal/europython-2018… (run by the Edinburgh Convention Bureau) Update on EuroPython 2018 ------------------------- Meanwhile, we wanted to give you an update of where we are with the conference organization: We are still working on getting everything setup for launching the website, opening ticket sales and the Call for Proposals (CFP). This year the EuroPython Society (EPS) will be running the ticket sales, rather than a local organization and we are facing some challenges related to VAT taxes, which are taking longer to sort out than expected. This is the main reason for the delay you are seeing, but we’re getting there. Enjoy, -- EuroPython 2018 Team https://ep2018.europython.eu/ https://www.europython-society.org/ PS: Please forward or retweet to help us reach all interested parties: https://twitter.com/europython/status/971716086445027328 Thanks.

cx_Oracle 6.2
by Anthony Tuininga 05 Mar '18

05 Mar '18

What is cx_Oracle? cx_Oracle is a Python extension module that enables access to Oracle Database for Python 3.x and 2.x and conforms to the Python database API 2.0 specifications with a number of enhancements. Where do I get it? https://oracle.github.io/python-cx_Oracle The easiest method to install/upgrade cx_Oracle is via pip as in python -m pip install cx_Oracle --upgrade What's new? This release eliminates the error "DPI-1054: connection cannot be closed when open statements or LOBs exist". It also adds support for creating temporary LOBs and binding LOBs directly to a cursor. You can now also use a connection as a context manager to close the connection at the end of the block by using the new cx_Oracle.__future__ object ( http://cx-oracle.readthedocs.io/en/latest/module.html#cx_Oracle.__future__). This will become the default and only behaviour of using a connection as a context manager unless I hear otherwise! The code was reorganised and simplified in order to streamline further maintenance and a number of bugs were fixed. The full release notes can be read here: http://cx-oracle.readthedocs.io/en/latest/releasenotes.html#version-6-2-mar… Please provide any feedback via GitHub issues ( https://github.com/oracle/python-cx_Oracle/issues).

Minor features: - Code cleanup: fix code style to satisfy flake8 linter. Documentation: - Rename www directory to docs. Tests: - Run pypy tests at AppVeyor. - Use remove-old-files.py from ppu to cleanup pip cache at Travis and AppVeyor. What is CheetahTemplate3 ======================== Cheetah3 is a free and open source template engine. It's a fork of the original CheetahTemplate library. Python 2.7 or 3.3+ is required.
