14:38
Space to hold the ".width" of columns in the CLI is now obtained from malloc() and hence is not limited in the number of columns supported. (check-in: 445ed5da user: drh tags: trunk)

00:45
When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index.
