[sympy] Should we drop 2.5 support?

2012-05-24 Thread Joachim Durchholz
I just visited the python.org website and found that 2.5 does not get security fixes anymore. The last release was in May 26th, 2011. What's the policy for which Python versions SymPy should support? Possible reasons to keep 2.5 support: Note that it is possible to run unsafe software if you

One of the main reasons to keep 2.5 support was for the App Engine, but I believe it now supports 2.7. I don't know of any major features from 2.6 that we're missing. I guess you could check the compatibility file to get an idea. I know it's not even close to the way it was with 2.4. I couldn't wai

If this is a vote, I vote for dropping 2.5. The app engine does support 2.7. You can not install 2.5 in the latests debian (from the official repos). If you are stuck on an old platform compiling 2.7 in home is *extremely* easy (you must have gcc). -- You received this message because you are su

Executive summary: From my perspective, I think that - the language and stdlib changes of 2.6 would be Nice To Have (TM) - the security issues are relevant enough to warrant dropping 2.5 - the case for keeping 2.5 is user base. Do we have data that allows us to judge its relevance? Am 25.05.20

People should be warned in good time, to have time to switch. ¿What about announcing that next released version will have 2.5 support, but after that it will be dropped? Kjetil On Thu, May 24, 2012 at 8:06 PM, Joachim Durchholz wrote: > Executive summary: > > From my perspective, I think that >

Yes, I think we would do that. We went to a lot of trouble to release 0.6.7 with Python 2.4 support before we dropped it, and it worked out, so I think it's a good plan for future Python version support drops (which shouldn't be nearly as hard, until we drop Python 2 support). Aaron Meurer On Th

Another reason to keep Python 2.5 (for more time) support : - some mobile OS only have Python 2.5.x, like Maemo 4 (Nokia N8x0), Maemo 5 (Nokia N900) and Symbian (many smartphones); - softwares (SymPy Interactive Shell, Integrate, Derivative and Limit) using SymPy on Maemo 5 OS have 100-150 t
