Eventlet 0.16.1
by Sergey Shepelev Jan. 14, 2015

Jan. 14, 2015

Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. http://pypi.python.org/pypi/eventlet/0.16.1 This release features Python 2.7.9 SSL compatibility and improved Python3 support (bleeding edge, not finished officially). Thanks to all contributors! Also, we removed lots of deprecated unsupported code, including Twisted hub. This will allow us to focus on what's important and get there sooner. Next targets: Python3 and IPv6. Important note if you already installed v0.16.0: please, take a minute and update your build to 0.16.1. Module eventlet.util was removed from source tree and tarball but still made it into wheel package by my mistake. You may have code that depends (but shouldn't) on this module and will work in some cases. News: * Fix SSL socket wrapping and Python 2.7.9 compatibility; Thanks to Jakub Stasiak * Fix monkey_patch() on Python 3; Thanks to Victor Stinner * Fix "maximum recursion depth exceeded in GreenSocket.__del__"; Thanks to Jakub Stasiak * db_pool: BaseConnectionPool.clear updates .current_size #139; Thanks to Andrey Gubarev * Fix __str__ method on the TimeoutExpired exception class.; Thanks to Tomaz Muraus * hubs: drop Twisted support * Removed deprecated modules: api, most of coros, pool, proc, processes and util * Improved Python 3 compatibility (including patch by raylu); Thanks to Jakub Stasiak * Allow more graceful shutdown of wsgi server; Thanks to Stuart McLaren * wsgi.input: Make send_hundred_continue_headers() a public API; Thanks to Tushar Gohad * tpool: Windows compatibility, fix ResourceWarning.

ANN: Bokeh 0.7.1 released
by Damian Avila Jan. 13, 2015

Jan. 13, 2015

On behalf of the Bokeh team, I am very happy to announce the release of Bokeh version 0.7.1! Bokeh is a Python library for visualizing large and realtime datasets on the web. Its goal is to provide to developers (and domain experts) with capabilities to easily create novel and powerful visualizations that extract insight from local or remote (possibly large) data sets, and to easily publish those visualization to the web for others to explore and interact with. This release was focused on stability, bug fixes, improved documentation and better examples. * Several bokeh.charts bug fixes and enhancements, such as configurable tools * Docs improvements, in particular, documenting json for bokeh.models * Mpl compatility improved, now returning the plot object * A lot of encoding fixes, including fixes in some of our sample data * Faster runs in TravisCI using the new docker-based containerized infrastructure * New and improved examples, such as the Interactive Image Processing with Numba and Bokeh notebook You can also see the CHANGELOG for full details. We would like to mention that we are working hard to provide new language binding for Bokeh. Anyone interested in developing new language bindings is encouraged to contact us to request any help to make this happen quickly and to host your project under the Bokeh organization umbrella. Also, the release of Bokeh 0.8 should happen in early 2015. Some notable features we intend to work on are: * R language binding * Simplifying production and multi-user Bokeh server deployments * CLI interface * Colorbar axis and axis location inspectors * Better support for maps and projections As usual, don't forget to check out the full documentation, interactive gallery, and tutorial at http://bokeh.pydata.org as well as the Bokeh IPython notebook nbviewer index (including all the tutorials) at: http://nbviewer.ipython.org/github/bokeh/bokeh-notebooks/blob/master/index.… To install the latest release, if you are using Anaconda, you can install it with conda: conda install bokeh Alternatively, you can install it with pip: pip install bokeh BokehJS is also available by CDN for use in standalone Javascript applications: http://cdn.pydata.org/bokeh-0.7.1.min.js http://cdn.pydata.org/bokeh-0.7.1.min.css Finally, BokehJS is also installable with the Node Package Manager. Issues, enhancement requests, and pull requests can be made on the Bokeh Github page: https://github.com/bokeh/bokeh Questions can be directed to the Bokeh mailing list: bokeh(a)continuum.io Thank you for your attention!

IMAPClient 0.12
by Menno Smits Jan. 12, 2015

Jan. 12, 2015

IMAPClient is an easy-to-use, Pythonic and complete IMAP client library. Version 0.12 has just been released with the following highlights: * Unicode handling has been fixed. Some bad decisions were made during the Python 3 port (v0.10) and this release fixes that. Bytes are now returned in most places (instead of unicode strings). * MODSEQ parts in SEARCH responses are now handled correctly. A crash has been fixed when MODSEQ queries (part of the CONDSTORE extension) are made with the search method. The returned MODSEQ value is now available via the "modseq" attribute on the returned list of ids. * Extra __init__ keyword args are passed through. This allows access to SSL options that the underlying imaplib library might support (Python version dependent). * Python 3.4 is now officially supported. * More control over OAUTH2 parameters. * The deprecated get_folder_delimiter() method has been removed. Many thanks go to Inbox for sponsoring the significant unicode changes in this release. More about them at http://inboxapp.com/. More details about this release can be found at: * https://bitbucket.org/mjs0/imapclient/src/tip/NEWS.rst * http://imapclient.readthedocs.org/en/0.12/ * http://imapclient.freshfoo.com/ * https://pypi.python.org/pypi/IMAPClient/0.12

[ANN] bcolz v0.8.0
by Valentin Haenel Jan. 9, 2015

Jan. 9, 2015

====================== Announcing bcolz 0.8.0 ====================== What's new ========== This version adds a public API in the form of a Cython definitions file (``carray_ext.pxd``) for the ``carray`` class! This means, other libraries can use the Cython definitions to build more complex programs using the objects provided by bcolz. In fact, this feature was specifically requested and there already exists a nascent application called *bquery* (https://github.com/visualfabriq/bquery) which provides an efficient out-of-core groupby implementation for the ``ctable`` object Because this is a fairly sweeping change, the minor version number was incremented and no additional major features or bugfixes were added to this release. We kindly ask any users of bcolz to try this version carefully and report back any issues, bugs, or even slow-downs you experience. I.e. please, please be careful when deploying this version into production. Many, many kudos to Francesc Elies and Carst Vaartjes of Visualfabriq for their hard work, continued effort to push this feature and their work on bquery which makes use of it! What it is ========== *bcolz* provides columnar and compressed data containers that can live either on-disk or in-memory. Column storage allows for efficiently querying tables with a large number of columns. It also allows for cheap addition and removal of column. In addition, bcolz objects are compressed by default for reducing memory/disk I/O needs. The compression process is carried out internally by Blosc, an extremely fast meta-compressor that is optimized for binary data. Lastly, high-performance iterators (like ``iter()``, ``where()``) for querying the objects are provided. bcolz can use numexpr internally so as to accelerate many vector and query operations (although it can use pure NumPy for doing so too). numexpr optimizes the memory usage and use several cores for doing the computations, so it is blazing fast. Moreover, since the carray/ctable containers can be disk-based, and it is possible to use them for seamlessly performing out-of-memory computations. bcolz has minimal dependencies (NumPy), comes with an exhaustive test suite and fully supports both 32-bit and 64-bit platforms. Also, it is typically tested on both UNIX and Windows operating systems. Together, bcolz and the Blosc compressor, are finally fulfilling the promise of accelerating memory I/O, at least for some real scenarios: http://nbviewer.ipython.org/github/Blosc/movielens-bench/blob/master/queryi… Other users of bcolz are Visualfabriq (http://www.visualfabriq.com/) the Blaze project (http://blaze.pydata.org/) and Quantopian (https://www.quantopian.com/) which you can read more about by pointing your browser at the links below. * Visualfabriq: * *bquery*, A query and aggregation framework for Bcolz: * https://github.com/visualfabriq/bquery * Blaze: * Notebooks showing Blaze + Pandas + BColz interaction: * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-csv.ipynb * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-bcolz.ip… * Quantopian: * Using compressed data containers for faster backtesting at scale: * https://quantopian.github.io/talks/NeedForSpeed/slides.html Installing ========== bcolz is in the PyPI repository, so installing it is easy:: $ pip install -U bcolz Resources ========= Visit the main bcolz site repository at: http://github.com/Blosc/bcolz Manual: http://bcolz.blosc.org Home of Blosc compressor: http://blosc.org User's mail list: bcolz(a)googlegroups.com http://groups.google.com/group/bcolz License is the new BSD: https://github.com/Blosc/bcolz/blob/master/LICENSES/BCOLZ.txt Release notes can be found in the Git repository: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst ---- **Enjoy data!**
