by Giampaolo Rodola' May 4, 2018

May 4, 2018

Hello all, I'm glad to announce the release of pyftpdlib 1.5.4: https://github.com/giampaolo/pyftpdlib About ===== Python FTP server library provides a high-level portable interface to easily write very efficient, scalable and asynchronous FTP servers with Python. What's new ========== **Enhancements** - #463: FTPServer class can now be used as a context manager. **Bug fixes** - #431: Ctrl-C doesn't exit `python -m pyftpdlib` on Windows. - #436: ThreadedFTPServer.max_cons is evaluated threading.activeCount(). If the user uses threads of its own it will consume the number of max_cons. - #447: ThreadedFTPServer and MultiprocessFTPServer do not join() tasks which are no longer consuming resources.

[RELEASE] Python 3.7.0b4, final 3.7 beta, now available for testing
by Ned Deily May 3, 2018

May 3, 2018

Python 3.7.0b4 is the final beta preview of Python 3.7, the next feature release of Python. Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare your projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. Attention macOS users: there is now a new installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant is expected to become the default version when 3.7.0 releases. Check it out! The next preview release will be the release candidate and is planned for 2018-05-21 followed by the official release of 3.7.0, planned for 2018-06-15. You can find Python 3.7.0b4 and more information here: https://www.python.org/downloads/release/python-370b4/ -- Ned Deily nad(a)python.org -- []

ANN: NumExpr 2.6.5
by Robert McLeod May 1, 2018

May 1, 2018

========================== Announcing Numexpr 2.6.5 ========================== Hi everyone, This is primarily an incremental performance improvement release, especially with regards to improving import times of downstream packages (e.g. `pandas`, `tables`, `sympy`). Import times have been reduced from ~300 ms to ~100 ms through removing a `pkg_resources` import and making the `cpuinfo` import lazy. The maximum number of threads is now set at import-time, similar to `numba`, by setting an environment variable 'NUMEXPR_MAX_THREADS'. The runtime number of threads can still be reduced by calling `numexpr.set_num_threads(N)`. DEPRECATION WARNING: The variable `numexpr.is_cpu_amd_intel` has been set to a dummy value of `False`. This variable may be removed in the future. Project documentation is available at: http://numexpr.readthedocs.io/ Changes from 2.6.4 to 2.6.5 --------------------------- - The maximum thread count can now be set at import-time by setting the environment variable 'NUMEXPR_MAX_THREADS'. The default number of max threads was lowered from 4096 (which was deemed excessive) to 64. - A number of imports were removed (pkg_resources) or made lazy (cpuinfo) in order to speed load-times for downstream packages (such as `pandas`, `sympy`, and `tables`). Import time has dropped from about 330 ms to 90 ms. Thanks to Jason Sachs for pointing out the source of the slow-down. - Thanks to Alvaro Lopez Ortega for updates to benchmarks to be compatible with Python 3. - Travis and AppVeyor now fail if the test module fails or errors. - Thanks to Mahdi Ben Jelloul for a patch that removed a bug where constants in `where` calls would raise a ValueError. - Fixed a bug whereby all-constant power operations would lead to infinite recursion. -- Robert McLeod, Ph.D. robbmcleod(a)gmail.com robbmcleod(a)protonmail.com robert.mcleod(a)hitachi-hhtc.ca www.entropyreduction.al

[RELEASE] Python 2.7.15
by Benjamin Peterson May 1, 2018

May 1, 2018

Greetings, I'm pleased to announce the immediate availability of Python 2.7.15, the latest bug fix release in the senescent Python 2.7 series. Source and binary downloads may be found on python.org: https://www.python.org/downloads/release/python-2715/ Bugs should be reported to https://bugs.python.org/ The source tarball contains a complete changelog in the Misc/NEWS file. The only change since the release candidate is a fix for undefined C behavior that newer compilers (including GCC 8) have started to exploit. Users of the macOS binaries should note that all python.org macOS installers now ship with a builtin copy of OpenSSL. Additionally, there is a new additional installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. See the installer README for more information. Happy May, Benjamin 2.7 release manager
