Good plan; there have been quite a few changes (also in the interface) from 2.5 to 2.6, but 2.7 (being a stable release) will be close to 2.6.2.

This version compiles fine, but there are about a million doctest failures :-(

This is a serious regression:

sage: EllipticCurve('90c3').integral_points(both_signs=False)
[(-15 : 7 : 1), (1 : 39 : 1), (21 : 79 : 1)]

Replying to @jdemeyer:

Peter, could you please add some documentation for the application of Sturm's Theorem in ell.gp? I checked the calculations by hand and it looks correct, but it would be nice to have the calculation as comment in the file.

Done in the above commit.

I'm getting merge failures, will release beta1 soon. Please merge with that release then.

OK, I will do that. Unfortunately, this ticket tends to give a lot of conflicts because it touches so much code (in a way which cannot really be avoided). For beta2, I hope you will give this ticket priority and ask other branches to merge with this.

I've released beta1, if you can resolve the conflicts soon then I'll merge this as the first ticket.

Done. I'm running doctests now to check that nothing got broken.

This branch agrees (up to whitespace) with a merge I did. If it passes doctests, you can set it back to positive review.
