-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm happy to announce the second alpha release of Python 3.3.0. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features and changes in the 3.3 release series are: * PEP 380, Syntax for Delegating to a Subgenerator ("yield from") * PEP 393, Flexible String Representation (doing away with the distinction between "wide" and "narrow" Unicode builds) * PEP 409, Suppressing Exception Context * PEP 3151, Reworking the OS and IO exception hierarchy * A C implementation of the "decimal" module, with up to 80x speedup for decimal-heavy applications * The new "packaging" module, building upon the "distribute" and "distutils2" projects and deprecating "distutils" * The new "lzma" module with LZMA/XZ support * PEP 3155, Qualified name for classes and functions * PEP 414, explicit Unicode literals to help with porting * The new "faulthandler" module that helps diagnosing crashes * Wrappers for many more POSIX functions in the "os" and "signal" modules, as well as other useful functions such as "sendfile()" * Hash randomization, introduced in earlier bugfix releases, is now switched on by default. For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html (*) To download Python 3.3.0 visit: http://www.python.org/download/releases/3.3.0/ Please consider trying Python 3.3.0 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy!

RedNotebook 1.4
by Jendrik Seipp 01 Apr '12

01 Apr '12

A new RedNotebook version has been released. You can get the tarball, the Windows installer and links to distribution packages at http://rednotebook.sourceforge.net/downloads.html What is RedNotebook? -------------------- RedNotebook is a **graphical journal** and diary helping you keep track of notes and thoughts. It includes a calendar navigation, customizable templates, export functionality and word clouds. You can also format, tag and search your entries. RedNotebook is available in the repositories of most common Linux distributions and a Windows installer is available. It is written in Python and uses GTK+ for its interface. What's new? ----------- * Search: If a search contains a hashtag (e.g. #Work or #Movies), only days with all of those tags will be searched. This means you can e.g. search for "project-xyz" only in the days tagged with "Work" with the query "#Work project-xyz". * Search for combinations of tags (e.g. #magazine #linux) * Search: If the query only contains a single hashtag (e.g. #Movies), a list of all subtags (the names of the movies) is shown. * Search: Automatically scroll to found text in edit mode * Split tag and word clouds * Show tag and word cloud only if there are any tags and words respectively * Remove spaces from multi-word tags during search and in clouds * Auto-complete tags in search * Always include all tags regardless of their frequency in the cloud * Exports: Correctly set the appropriate extension for each export type * Exports: Always add a title for LaTeX exports * Fix: Correctly parse configuration values containing ='s * Fix: Paths returned from file and folder choosers must be converted to unicode * Fix: Correctly redirect error output into the logfile on Windows * Updated translations Cheers, Jendrik

ANN: Spyder v2.1.9
by Pierre Raybaut 01 Apr '12

01 Apr '12

Hi all, On the behalf of Spyder's development team (http://code.google.com/p/spyderlib/people/list), I'm pleased to announce that Spyder v2.1.9 has been released and is available for Windows XP/Vista/7, GNU/Linux and MacOS X: http://code.google.com/p/spyderlib/ This is a pure maintenance release -- a lot of bugs were fixed since v2.1.8: http://code.google.com/p/spyderlib/wiki/ChangeLog Spyder is a free, open-source (MIT license) interactive development environment for the Python language with advanced editing, interactive testing, debugging and introspection features. Originally designed to provide MATLAB-like features (integrated help, interactive console, variable explorer with GUI-based editors for dictionaries, NumPy arrays, ...), it is strongly oriented towards scientific computing and software development. Thanks to the `spyderlib` library, Spyder also provides powerful ready-to-use widgets: embedded Python console (example: http://packages.python.org/guiqwt/_images/sift3.png), NumPy array editor (example: http://packages.python.org/guiqwt/_images/sift2.png), dictionary editor, source code editor, etc. Description of key features with tasty screenshots can be found at: http://code.google.com/p/spyderlib/wiki/Features On Windows platforms, Spyder is also available as a stand-alone executable (don't forget to disable UAC on Vista/7). This all-in-one portable version is still experimental (for example, it does not embed sphinx -- meaning no rich text mode for the object inspector) but it should provide a working version of Spyder for Windows platforms without having to install anything else (except Python 2.x itself, of course). Don't forget to follow Spyder updates/news: * on the project website: http://code.google.com/p/spyderlib/ * and on our official blog: http://spyder-ide.blogspot.com/ Last, but not least, we welcome any contribution that helps making Spyder an efficient scientific development/computing environment. Join us to help creating your favourite environment! (http://code.google.com/p/spyderlib/wiki/NoteForContributors) Enjoy! -Pierre
