About SymPy history on Maemo, MeeGo and Sailfish/Mer :

- SymPy 0.6.6 (December 2009) was released on January 2010 for Maemo 5 by Tom Tanner;

- SymPy 0.7.1 (29/06/2011) was released on September 12th 2011 for Maemo 5, with the "SymPy Interactive Shell" package including an icon and isympy so SymPy is more visible to end users. Plotting was available using "Plot()" with PyGlet and mpmath plotting with MatPlotLib;

- SymPy 0.7.1 was released on October 3rd 2011 for Maemo 4, then the "SymPy Interactive Shell" package in 22/02/2012 (after IPython 0.10.2 release on Maemo 4), with no plotting options;

- SymPy 0.7.1 for MeeGo Harmattan was released on 06/11/2011, with mpmath plotting using MatPlotLib;

- SymPy 0.7.2 (16/10/2012) was released on 03/01/2013 for MeeGo Harmattan and on 09/01/2013 for Maemo 4 and Maemo 5. With this version, there are 3 plotting options on Maemo 5 ("Plot()" using PyGlet , new plotting module and mpmath plotting with MatPlotLib) and 2 plotting options on MeeGo Harmattan (new plotting module and mpmath plotting with MatPlotLib);

- SymPy 0.7.3 (13/07/2013) released on 05/08/2013 for Maemo 4, Maemo 5 and MeeGo Harmattan. Due to Python 2.5 limitation, this is the last version for Maemo 4, and maybe also for Maemo 5. This version has 2 plotting options on Maemo 5 ( "Plot()" using PyGlet and mpmath plotting with MatPlotLib) and 2 plotting options on MeeGo Harmattan (new plotting module and mpmath plotting with MatPlotLib).

- SymPy 0.7.5 (22/04/2014) released on 04/05/2014 for Sailfish.

- SymPy 0.7.4.1 (15/12/2013) released on 23/09/2014 for MeeGo Harmattan.

- SymPy 0.7.5 (22/02/2014) released on 24/09/2014 for MeeGo Harmattan.

- SymPy 0.7.6.1 (03/09/2015) released on 07/08/2016 for Sailfish, both for Python 2.7 and Python 3.

I plan to keep SymPy for Maemo / MeeGo / Mer updated.

SymPy is developed by the SymPy team. I am mainly a maintainer of SymPy for Maemo, with just one small source code contribution to SymPy.
