// Release Notes for the Martin-Quinn Scores 2021 Term Release
// 10/17/2022

With the release of the legacy Supreme Court Database (from 1791-1945)
we have rebuilt all of the data files used to estimate the
Martin-Quinn scores.  Prior to the release of the 2015 Martin-Quinn
scores, we had been using data from the legacy Spaeth database, some
data collected for other purposes for 1937-1941, and adding data for
each subsequent term from the modern Supreme Court Database.  From the
2015 release on, we have rebuilt all of the data files using the
latest version of the modern and legacy versions of the Supreme Court
Database from http://supremecourtdatabase.org.  The resulting data
file used to fit the model is now available on our replication page.

Because various errors were found and corrected between the legacy
Spaeth database and the modern Supreme Court Database, some slight
changes have emerge for some justices between this release and
previous releases.  All justices now receive a score so long as they
participated in at least one case in a term.
