Just this week I worked a bit with Python 2.6 to see what the issues are going to be. There are some problems. The Boost libraries, which enhance C++, have to be built for a specific version of Python, and since there aren't yet available these binaries for 2.6, I built them from source. Similarly for numpy. Turns out that something has changed in these components, because there's now a type mismatch between numpy integers and Python integers (this is a simplified description). Moreover, for the new Visual about to be released, there's a problem with a native-mode version for the Mac because the Mac Python 2.6 has an IDLE that won't run!</p> <p>Summary: There are various problems in the Python 2.6 world. But we'll be tracking them and looking for solutions. We would prefer to release the new Visual for Python 2.6, because the new Python builds a bridge between Python 2.5 and the coming Python 3.0, a version of Python that will actually break some existing programs. Python 2.6 offers tools to check on possible incompatibilities.</p> <p>------------------------<br> </p> <p>Also, from James Mueller:<br> </p> <p>2.6 only came out in October, so numpy will probably be less than 6 months behind. It would be earlier, but they have other things to take care of first. Most linux distributions are planning to roll out 2.6 over the next 6 months, so that is the time scale they are looking at. 2.6 might also be the python when OS X 10.6 comes out. 3.0 is a BIG change, which is why they estimate a year to get numoy ported. I expect a lot of projects will take some time to move from the 2.x series to 3.x. There are a lot of non-backward-compatible syntax changes. </p> </div> <br> Joe Heafner wrote: <blockquote cite="mid:e7f...@ma..." type="cite">Would updating Mac Python from 2.5.2 to 2.6.x break the latest Visual? <div><br> </div> <div>Joe</div> <pre wrap=""> <hr size="4" width="90%"> ------------------------------------------------------------------------------ </pre> <pre wrap=""> <hr size="4" width="90%"> _______________________________________________ Visualpython-users mailing list <a class="moz-txt-link-abbreviated" href="mailto:Vis...@li...">Vis...@li...</a> <a class="moz-txt-link-freetext" href="https://lists.sourceforge.net/lists/listinfo/visualpython-users">https://lists.sourceforge.net/lists/listinfo/visualpython-users</a> </pre> </blockquote> </body> </html> |
