Release: Celery 4.0 (latentcall)
by Ask Solem 07 Nov '16

07 Nov '16

I'm happy to announce that a new major version of Celery has been released! To see the complete list of changes go here: [http://docs.celeryproject.org/en/latest/whatsnew-4.0.html](https://link.nyl… .com/link/c6kbuz4icejw17oc3qqi6syrm/local-d891639d-1557/0?redirect=http%3A%2F% 2Fdocs.celeryproject.org%2Fen%2Flatest%2Fwhatsnew-4.0.html&r=cHl0aG9uLWFubm91b mNlLWxpc3RAcHl0aG9uLm9yZw==) This is a massive release with over two years of changes. Not only does it come with many new features, but it also fixes a massive list of bugs, so in many ways you could call it our "Snow Leopard" release. The next major version of Celery will support Python 3.5 only, were we are planning to take advantage of the new asyncio library. This release would not have been possible without the support of my employer, Robinhood (we're hiring! [http://robinhood.com](https://link.nylas.com/link/c6kbuz4icejw17oc3qqi6syrm /local-d891639d-1557/1?redirect=http%3A%2F%2Frobinhood.com&r=cHl0aG9uLWFubm91b mNlLWxpc3RAcHl0aG9uLm9yZw==)). It's important that you read the "What's new in Celery 4.0" document before you upgrade, and since the list of changes is far too big to put in an email you have to visit the documentation: [http://docs.celeryproject.org/en/latest/whatsnew-4.0.html](https://link.nyl… .com/link/c6kbuz4icejw17oc3qqi6syrm/local-d891639d-1557/2?redirect=http%3A%2F% 2Fdocs.celeryproject.org%2Fen%2Flatest%2Fwhatsnew-4.0.html&r=cHl0aG9uLWFubm91b mNlLWxpc3RAcHl0aG9uLm9yZw==) Thank you for your support, \-- [ Ask Solem - github.com/ask | twitter.com/asksol ]

06 Nov '16

Hello all, I'm glad to announce the release of psutil 5.0.0: https://github.com/giampaolo/psutil This release introduces important speedups making psutil from 2x to 6x faster depending on what platform you're on. A full blog post can be found here: http://grodola.blogspot.com/2016/11/psutil-500-is-around-twice-as-fast.html About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6 to 3.5 (users of Python 2.4 and 2.5 may use 2.1.3 version). PyPy is also known to work. What's new ========== *2016-11-06* **Enhncements** - #799: new Process.oneshot() context manager making Process methods around +2x faster in general and from +2x to +6x faster on Windows. - #943: better error message in case of version conflict on import. **Bug fixes** - #932: [NetBSD] net_connections() and Process.connections() may fail without raising an exception. - #933: [Windows] memory leak in cpu_stats() and WindowsService.description().

SCons 2.5.1 Released
by Bill Deegan 05 Nov '16

05 Nov '16

Available at: https://sourceforge.net/projects/scons/files/latest/download?source=files Changelog: SCons - a software construction tool Change Log RELEASE 2.5.1 - Mon, 03 Nov 2016 13:37:42 -0400 From William Deegan: - Add scons-configure-cache.py to packaging. It was omitted From Alexey Klimkin: - Use memoization to optimize PATH evaluation across all dependencies per node. (PR #345) RELEASE 2.5.0 - Mon, 09 Apr 2016 11:27:42 -0700 From Dirk Baechle: - Removed a lot of compatibility methods and workarounds for Python versions < 2.7, in order to prepare the work towards a combined 2.7/3.x version. (PR #284) Also fixed the default arguments for the print_tree and render_tree methods. (PR #284, too) From William Blevins: - Added support for cross-language dependency scanning; SCons now respects scanner keys for implicit dependencies. - Notes for SCons users with heterogeneous systems. - May find new (previously missed) dependencies. - May cause rebuild after upgrade due to dependency changes. - May find new dependency errors (EG. cycles). - Discovered in some of the SCons QT tests. - Resolved missing cross-language dependencies for SWIG bindings (fixes #2264). - Corrected typo in User Guide for Scanner keyword. (PR #2959) - Install builder interacts with scanner found in SCANNERS differently. - Previous: Install builder recursively scanned implicit dependencies for scanners from SCANNER, but not for built-in (default) scanners. - Current: Install builder will not scan for implicit dependencies via either scanner source. This optimizes some Install builder behavior and brings orthogonality to Install builder scanning behavior. From William Deegan: - Add better messaging when two environments have different actions for the same target (Bug #2024) - Fix issue only with MSVC and Always build where targets marked AlwaysBuild wouldn't make it into CHANGED_SOURCES and thus yield an empty compile command line. (Bug #2622) - Fix posix platform escaping logic to properly handle paths with parens in them "()". (Bug #2225) From Jakub Pola: - Intel Compiler 2016 (Linux/Mac) update for tool directories. From Adarsh Sanjeev: - Fix for issue #2494: Added string support for Chmod function. From Tom Tanner: - change cache to use 2 character subdirectories, rather than one character, so as not to give huge directories for large caches, a situation which causes issues for NFS. For existing caches, you will need to run the scons-configure-cache.py script to update them to the new format. You will get a warning every time you build until you co this. - Fix a bunch of unit tests on windows

ANN: PyWavelets v0.5.0 release
by Gregory Lee 03 Nov '16

03 Nov '16

On behalf of the PyWavelets development team I am pleased to announce the release of PyWavelets 0.5.0. PyWavelets is a Python toolbox implementing both discrete and continuous wavelet transforms (mathematical time-frequency transforms) with a wide range of built-in wavelets. C/Cython are used for the low-level routines, enabling high performance. Key Features of PyWavelets are: * 1D, 2D and nD Forward and Inverse Discrete Wavelet Transform (DWT and IDWT) * 1D, 2D and nD Multilevel DWT and IDWT * 1D and 2D Forward and Inverse Stationary Wavelet Transform * 1D and 2D Wavelet Packet decomposition and reconstruction * 1D Continuous Wavelet Transform * When multiple valid implementations are available, we have chosen to maintain consistency with MATLAB's Wavelet Toolbox. PyWavelets 0.5.0 is the culmination of 1 year of work. In addition to several new features, substantial refactoring of the underlying C and Cython code have been made. Highlights of this release include: - 1D continuous wavelet transforms - new discrete wavelets added (additional Debauchies and Coiflet wavelets) - new 'reflect' extension mode for discrete wavelet transforms - faster performance for multilevel forward stationary wavelet transforms (SWT) - n-dimensional support added to forward SWT - routines to convert multilevel DWT coefficients to and from a single array - axis support for multilevel DWT - substantial refactoring/reorganization of the underlying C and Cython code Full details in the release notes at: http://pywavelets.readthedocs.io/en/latest/release.0.5.0.html This release requires Python 2.6, 2.7 or 3.3-3.5 and Numpy 1.9.1 or greater. Sources can be found on https://pypi.python.org/pypi/PyWavelets and https://github.com/PyWavelets/pywt/releases. As always, new contributors are welcome to join us at https://github.com/PyWavelets/pywt
