[RELEASE] Python 2.7.9
by Benjamin Peterson Dec. 10, 2014

Dec. 10, 2014

It is my pleasure to announce the release of Python 2.7.9, a new bugfix release in the Python 2.7 series. Despite technically being a maintenance release, Python 2.7.9 includes several majors changes from 2.7.8: - The "ensurepip" module has been backported to Python 2.7 - Python 3's ssl module has been backported to Python 2.7. - HTTPS certificates are now verified by default using the system's certificate store. - SSLv3 has been disabled by default due to the POODLE attack. Downloads are at https://www.python.org/downloads/release/python-279/ Please report bugs to https://bugs.python.org/ I would like to thank the people who made the above security and usability improvements listed above possible. Among others, Alex Gaynor, David Reid, Nick Coghlan, and Donald Stufft wrote many PEPs and a lot of code to bring those features to 2.7.9. Thank you. Enjoy, Benjamin 2.7 release manager on behalf on python-dev and all of Python's contributors

Eliot 0.6: Logging for Complex & Distributed Systems
by Itamar Turner-Trauring Dec. 10, 2014

Dec. 10, 2014

Eliot is a logging system designed not only for simple applications but for complex applications as well, including distributed systems. Eliot supports simple structured messages but can also record a causal chain of actions happening within and across process boundaries: a logical trace of the system's operation. Structured, action-oriented logging is a great help when debugging problems. For example, here are the combined logs of a request originating from a client process being sent to a server. Notice how easy it is to figure out the cause of the problem, even though it's opaque to the client: process='client' task_uuid='40be6df2' task_level=[1] action_type='main' action_status='started' process='client' task_uuid='40be6df2' task_level=[2, 1] action_type='http_request' action_status='started' x=5 y=0 process='server' task_uuid='40be6df2' task_level=[2, 2, 1] action_type='eliot:remote_task' action_status='started' process='server' task_uuid='40be6df2' task_level=[2, 2, 2, 1] action_type='divide' action_status='started' x=5 y=0 process='server' task_uuid='40be6df2' task_level=[2, 2, 2, 2] action_type='divide' action_status='failed' exception='exceptions.ZeroDivisionError' reason='integer division or modulo by zero' process='server' task_uuid='40be6df2' task_level=[2, 2, 3] action_type='eliot:remote_task' action_status='failed' exception='exceptions.ZeroDivisionError' reason='integer division or modulo by zero' process='client' task_uuid='40be6df2' task_level=[2, 3] action_type='http_request' action_status='failed' exception='requests.exception.HTTPError' reason='500 Server Error: INTERNAL SERVER ERROR' process='client' task_uuid='40be6df2' task_level=[3] action_type='main' action_status='failed' exception='requests.exception.HTTPError' reason='500 Server Error: INTERNAL SERVER ERROR' What's New in 0.6.0 Incompatible output format change! In previous versions the ordering of messages and actions was ambiguous and could not be deduced from out-of-order logs, and even where it was possible sorting correctly was difficult. To fix this the action_counter field was removed and now all messages can be uniquely located within a specific task by the values in an *improved task_level field* <http://eliot.readthedocs.org/en/0.6.0/fields.html#task-fields>. Features: - Eliot tasks can now *span multiple processes and threads* <http://eliot.readthedocs.org/en/0.6.0/threads.html#cross-process-tasks>, allowing for easy tracing of actions in distributed applications. - *eliot.add_global_fields* <http://eliot.readthedocs.org/en/0.6.0/output.html#add-global-fields> allows adding fields with specific values to all Eliot messages logged by your program. This can be used to e.g. distinguish between log messages from different processes by including relevant identifying information. Bug fixes: - On Python 3 files that accept unicode (e.g. sys.stdout) should now work. Downloads are available on PyPI <https://pypi.python.org/pypi/eliot>. Documentation can be found on Read The Docs <https://eliot.readthedocs.org/> . Bugs and feature requests should be filed at the project Github page <https://github.com/ClusterHQ/eliot>. You can ask for help on IRC at the #eliot channel on irc.freenode.net.

IronPython 2.7.5 Released
by Jeff Hardy Dec. 9, 2014

Dec. 9, 2014

On behalf of the IronPython team, I'm very happy to announce the release of IronPython 2.7.5[1]. Like all IronPython 2.7-series releases, .NET 4 is required to install it. Installing this release will replace any existing IronPython 2.7-series installation. Assemblies for embedding are provided for .NET 3.5, .NET 4, .NET 4.5, and Silverlight 5. IronPython 2.7.5 is primarily a collection of bug fixes[2] which smooths off many of the remaining rough edges. The complete list of changes[3] is also available. A major new feature is the inclusion of `ensurepip`, which will install the `pip` package manager: ``` ; -X:Frames is required when using pip ipy.exe -X:Frames -m ensurepip ; Run from an Administrator console if using IronPython installer ipy.exe -X:Frames -m pip install html5lib ``` **Note:** The assembly version of IronPython has changed to 2.7.5.0. All previous 2.7 versions had the same version (2.7.0.40) which caused issues when different versions were installed. Publisher policy files are used to so that applications don't have to be recompiled, but recompiling is strongly recommended. A huge thanks goes out to Pawel Jasinski, who contributed most of the changes in this release. Thanks is also due to Simon Opelt, Alex Earl, Jeffrey Bester, yngipy hernan, Alexander Köplinger,Vincent Ducros, and fdanny. For Visual Studio integration, check out Python Tools for Visual Studio[4] which has support for IronPython as well as CPython, and many other fantastic features. IronPython 2.7.5 is also available for embedding via NuGet. The main package is IronPython, and the standard library is in IronPython.StdLib. - Jeff [1] http://ironpython.codeplex.com/releases/view/169382 [2] http://bit.ly/ipy275fixed [3] https://github.com/IronLanguages/main/compare/ipy-2.7.4...ipy-2.7.5 [4] http://pytools.codeplex.com/

ANN: Bokeh 0.7 released
by Damian Avila Dec. 8, 2014

Dec. 8, 2014

On behalf of the Bokeh team, I am very happy to announce the release of Bokeh version 0.7! 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 includes many major new features: * IPython widgets and animations without a Bokeh server * Touch UI working for tools on mobile devices * Vastly improved linked data table * More new (and improving) bokeh.charts (high level charting interface) * Color mappers on the python side * Improved toolbar * Many new tools: lasso, poly, and point selection, crosshair inspector Check our blog post: http://continuum.io/blog/bokeh-0.7, to watch some of these tools in action! And you can also see the CHANGELOG for full details. We would like to mention that the Github Organization for Bokeh is growing! This organization was already home to bokeh-scala and bokeh.jl, and now the Bokeh project itself has a new home there as well, located at https://github.com/bokeh/bokeh. Anyone interested in developing new language bindings for Bokeh is encouraged to contact us about hosting your project under this organization. Also, the release of Bokeh 0.8 should happen in early 2015. Some notable features we intend to work on are: * Simplifying production and multi-user Bokeh server deployments * 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-0.7.0.min.js http://cdn.pydata.org/bokeh-0.7.0.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! Damián
