SQLite Release 3.50.1 On 2025-06-06

Add the sqlite3_setlk_timeout() interface which sets a separate timeout, distinct from the sqlite3_busy_timeout(), for blocking locks on builds that support blocking locks. The SQLITE_DBCONFIG_ENABLE_COMMENTS constraint (added in the previous release) is relaxed slightly so that comments are always allowed when reading the schema out of a pre-existing sqlite_schema table. Comments are only blocked in new SQL. New SQL functions: unistr() unistr_quote() For the %Q and %q conversions in the built-in printf() (which covers the sqlite3_mprintf() API and the format() SQL function and similar) the alternate-form-1 flag ("#") causes control characters to be converted into backslash-escapes suitable for unistr(). CLI enhancements: Avoids direct output of most control characters. The output of the .dump command makes use of the new unistr() SQL function to encode special characters, unless the --escape mode is set to off. Better formatting of complex partial indexes in the output from the ".schema --indent" command. .
