SQLite Release 3.50.0 On ?

  1. 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.
  2. 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.
  3. New SQL functions:
    1. unistr()
    2. unistr_quote()
  4. 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().
  5. CLI enhancements:
    1. Avoids direct output of most control characters.
    2. The output of the .dump command makes use of the new unistr() SQL funtion to encode special characters, unless the --escape mode is set to off.
    3. Better formatting of complex partial indexes in the output from the ".schema --indent" command.
  6. Improved support for building on Cygwin and MinGW and similar.
  7. Typo fixes in the documentation and in the source code comments.
  8. Miscellaneous performance improvements.

    Hashes:

  9. SQLITE_SOURCE_ID: pending
  10. SHA3-256 for sqlite3.c: pending
