Well, basically just get a Sage trac account (I think just email sage-trac-account https://groups.google.com/group/sage-trac-account for that), click on the trac ticket and click positive review:-) To actually to the review correctly, see the appropriate sections of the developer's manual http://www.sagemath.org/doc/developer/ (for example I like http://www.sagemath.org/doc/developer/producing_patches.html to apply patches). > > On Wed, Sep 14, 2011 at 3:31 PM, David Joyner <[email protected]> wrote: >> Hi all: >> >> Just a little reminder: there is a trac item in Sage detailing with >> the upgrade of >> Sympy to 0.7.1 (from 0.6.4).
