the left-hand side as long as the LIKE pattern on the right-hand side does not
begin with a digit or minus sign.
<li>Added the [sqlite3_set_last_insert_rowid()] interface and use that new interface in
the [FTS3], [FTS4], and [FTS5] extensions to ensure that the [sqlite3_last_insert_rowid()]
interface always returns reasonable values.
<li>Enhance [PRAGMA integrity_check] and [PRAGMA quick_check] so that they verify
[CHECK constraints].
<li>Enhance the query plans for joins to detect empty tables early
halt without doing unnecessary work.
<li>Various performance improvements.
<p><b>Bug Fixes:</b>
<li>Ensure that indexed expressions with collating sequences are handled correctly.
Fix for ticket [https://www.sqlite.org/src/info/eb703ba7b50c1a5|eb703ba7b50c1a5].
<li>Fix a bug in the 'start of ...' modifiers for the [date and time functions].

to put comma separators at the thousands marks for integers, if the "," format modifier
is used in between the "%" and the "d" (example: "%,d").
