This page documents all changes made to the database or calculation methodology. Calculated results from different database versions may differ.

Note: our database is incrementally built nightly.

Current Database versions

Version 2.0.0, Release Date: 04/13/2016

  • Equivalent to old version "2014.04.18"
  • Use major.minor.patch versioning, inspired by semantic versioning, but for data. Arbitrarily choose "2" as the initial major version.
  • When new data is added (typically nightly), db version remains the same
  • When new kinds of data are added, bump the patch (x.y.Z) version
  • When data organization (schema) changes, bump the minor (x.Y.z) version
  • When calculation methodology changes, bump the major (X.y.z) version
