set docs [list {
Enhance the INSERT syntax to allow multiple rows to be inserted via the
VALUES clause.
} {
Enhance the CREATE VIRTUAL TABLE command to support the IF NOT EXISTS clause.
} {
Added the sqlite3_stricmp() interface as a counterpart to sqlite3_strnicmp().
} {
Added the sqlite3_db_readonly() interface.
} {
Added the SQLITE_FCNTL_PRAGMA file control, giving VFS implementations the
ability to add new PRAGMA statements or to override built-in PRAGMAs.
} {
Queries of the form: "SELECT max(x), y FROM table" returns the value of y on
the same row that contains the maximum x value.
} {
Added support for the FTS4 languageid option.
} {
Documented support for the FTS4 content option. This feature has actually
been in the code since version 3.7.9 but is only now considered to be
officially supported.
} {
Pending statements no longer block ROLLBACK. Instead, the pending statement
will return SQLITE_ABORT upon next access after the ROLLBACK.
} {
Improvements to the handling of CSV inputs in the command-line shell
} {
Fix a bug introduced in version 3.7.10 that might cause a LEFT JOIN to be
incorrectly converted into an INNER JOIN if the WHERE clause indexable terms
connected by OR.
