=======================
Announcing bcolz 0.11.3
=======================
What's new
==========
Implemented new feature (#255): bcolz.zeros() can create new ctables
too, either empty or filled with zeros. (#256 @FrancescElies
@FrancescAlted).
Also, in previous, non announced versions (0.11.1 and 0.11.2), new
dependencies were added and other fixes are there too.
For a more detailed change log, see:
https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst
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:

Hello everybody,
on behalf of the PyInstaller development team I'm happy to announce
PyInstaller 3.0 after two years of development.
http://www.pyinstaller.org
=== What it is ===
PyInstaller bundles a Python application and all its dependencies into a
single package. The user can run the packaged app without installing a Python
interpreter or any modules.
PyInstaller reads a Python script written by you. It analyzes your code to
discover every other module and library your script needs in order to execute.
Then it collects copies of all those files - including the active Python
interpreter! - and puts them with your script in a single folder, or
optionally in a single executable file.
PyInstaller is tested against Windows, Mac OS X, and Linux. However, it is not
a cross-compiler: to make a Windows app you run PyInstaller in Windows; to
make a Linux app you run it in Linux, etc. PyInstaller has been used
successfully with AIX, Solaris, and FreeBSD, but is not tested against them.
=== Changes ===
Major changes for this release are:
- Python 3 support (3.3 / 3.4 / 3.5).
- Remove support for Python 2.6 and lower.
- Full unicode support in the bootloader (#824, #1224, #1323, #1340, #1396)
- (OSX) Executables built with PyInstaller under OS X can now be digitally
signed.
- (OSX) 32bit precompiled bootloader no longer distributed, only 64bit.
- (Windows) for 32bit bootloader enable flag LARGEADDRESSAWARE that allows
to use 4GB of RAM.
- New hooks: amazon-product-api, appy, certifi, countrycode, cryptography, gi,
httplib2, jsonschema, keyring, lensfunpy, mpl_toolkits.basemap, ncclient,
netCDF4, OpenCV, osgeo, patsy, PsychoPy, pycountry, pycparser, PyExcelerate,
PyGobject, pymssql, PyNaCl, PySiDe.QtCore, PySide.QtGui, rawpy, requests,
scapy, scipy, six, SpeechRecognition, u1db, weasyprint, Xlib.
- Add support for automatically including data files from eggs.
- Add support for directory eggs support.
- Add support for all kind of namespace packages.
- Add support for ``pkgutil.extend_path()``.
- New option ``--key`` to obfuscate the Python bytecode.
The full changelog for this release can be found at:
https://pypi.python.org/pypi/PyInstaller/3.0
=== License ===
PyInstaller is licensed under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2 of the License,
or (at your option) any later version.
Bootloader Exception
In addition to the permissions in the GNU General Public License, the
authors give you unlimited permission to link or embed compiled bootloader
and related files into combinations with other programs, and to distribute
those combinations without any restriction coming from the use of those
files. (The General Public License restrictions do apply in other respects;
for example, they cover modification of the files, and distribution when
not linked into a combine executable.)
=== Feedback ===
We're eager to listen to your feedback on using PyInstaller:

ANNOUNCING
eGenix PyRun - One file Python Runtime
Version 2.1.1
An easy-to-use single file relocatable Python run-time -
available for Linux, Mac OS X and Unix platforms,
with support for Python 2.6, 2.7 and
**now also for Python 3.4**.
This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-PyRun-2.1.1-GA.html
________________________________________________________________________
INTRODUCTION
eGenix PyRun is our open source, one file, no installation version of
Python, making the distribution of a Python interpreter to run based
scripts and applications to Unix based systems as simple as copying a
single file.
eGenix PyRun's executable only needs 11MB for Python 2 and 13MB for
Python 3, but still supports most Python application and scripts - and
it can be compressed to just 3-4MB using upx, if needed.
Compared to a regular Python installation of typically 100MB on disk,
eGenix PyRun is ideal for applications and scripts that need to be
distributed to several target machines, client installations or
customers.
It makes "installing" Python on a Unix based system as simple as
copying a single file.
eGenix has been using eGenix PyRun internally in the mxODBC Connect
Server product since 2008 with great success and decided to make it
available as a stand-alone open-source product.
We provide both the source archive to build your own eGenix PyRun, as
well as pre-compiled binaries for Linux, FreeBSD and Mac OS X, as 32-
and 64-bit versions. The binaries can be downloaded manually, or you
can let our automatic install script install-pyrun take care of the
installation: ./install-pyrun dir and you're done.
Please see the product page for more details:
http://www.egenix.com/products/python/PyRun/

NEWS
This patch level release of eGenix PyRun 2.1 comes with the following
enhancements:
Enhancements / Changes
----------------------
* Upgraded eGenix PyRun to work with and use Python 2.7.10 per
default.
* eGenix PyRun will now adjust sys.base_prefix and
sys.base_exec_prefix in the same way it does for sys.prefix and
sys.exec_prefix. This is needed for Python 3.4 in order to have
distutils find the Python.h include file when compiling C
extensions.
* PyRun for Python 3.4 will now show the correct file name of scripts
in tracebacks when running them directly, instead of just
'<string>'.
* The new internal _sysconfigdata module used by the sysconfig module
is now patched with the eGenix PyRun config data as well, to make
sure that PyRun doesn't ship with two sets of build config
variables.
install-pyrun Quick Install Enhancements
---------------------------------------------
eGenix PyRun includes a shell script called install-pyrun, which
greatly simplifies installation of PyRun. It works much like the
virtualenv shell script used for creating new virtual environments
(except that there's nothing virtual about PyRun environments).
https://downloads.egenix.com/python/install-pyrun
With the script, an eGenix PyRun installation is as simple as running:
./install-pyrun targetdir
This will automatically detect the platform, download and install the
right pyrun version into targetdir.
We have updated this script since the last release:
* Updated install-pyrun to default to eGenix PyRun 2.1.1 and its
feature set.
For a complete list of changes, please see the eGenix PyRun Changelog:

Dear all,
It is my pleasure to announce the next major version of the pysnmp package (4.3.0) on pypi.
This release brings many significant features:
* Pure-Python, automatic, on the fly MIB parsing.
* Rewritten synchronous high-level interface: walking SNMP agent becomes a matter of exhausting Python generator!
* Rewritten Twisted interface: now it is also high-level.
* Shiny new high-level asyncio/trollius interfaces.
Quite a lot of long-pending fixes ultimately went live. Despite many changes, backward compatibility with previous releases is largely preserved.
Finally, proper Sphinx-based documentation (http://pysnmp.sf.net <http://pysnmp.sf.net/>) now accompanies important pieces of the code.
Feedback, bug reports and suggestions are welcome!
