No new data since March 2021. Many script updates for scripts which prepare data for uploading to the LMFDB.

A draft release in March 2021 was never released. Notes from that follow:

Generators have been optimised: Minkowski-reduced with respect to the canonical height and then string-length-reduced with respect to adding torsion.

Many scripts changes for producing data for the LMFDB, for curves in this collection and elsewhere (Stein-Watkins, Bennett-Gherga-Rechnitzer).

New curvedata and classdata files added.

All conductors to 500000

In this release the conductor range is increased to 500000 (from 400000), torsion growth data now extends to fields of degree up to 23, and the data on optimality and the Manin constant has been updated.

All conductors to 400000

This release extends the range of conductors up to 400,000.

2016-02-07

This release extends the data to include all conductors up to 380000.

v.2015-09-07

No difference in data from previous release, but the repository has been reorganised and split to that branch gh-pages can serve the website at http://johncremona.github.io/ecdata/ .

2015-05-19

Added data for conductors 350000-359999

v.2015-02-11

All elliptic curve data for conductors up to 350000.
