<li>Allow [table-valued functions] to appear on the right-hand side of an [IN operator].
<li>Created the [dbhash.exe] command-line utility.
<li>Added two new C-language interfaces: [sqlite3_expanded_sql()] and
    [sqlite3_trace_v2()].  These new interfaces subsume the functions of
    [sqlite3_trace()] and [sqlite3_profile()] which are now deprecated.
<li>Added the [json_quote()] SQL function to [the json1 extension].
<li>Disable the [sqlite3_set_authorizer|authorizer callback] while reparsing the schema.


<p><b>Bug Fixes:</b>
<li>Fix the [ALTER TABLE] command so that it does not corrupt [descending indexes]
    when adding a column to a [legacy_file_format|legacy file format] database.  Ticket
    [https://www.sqlite.org/src/info/f68bf68513a1c15f|f68bf68513a1c15f]
<li>Fix a NULL-pointer dereference/crash that could occurs when a transitive WHERE
    clause references a non-existent collating sequence.  Ticket
    [https://www.sqlite.org/src/info/e8d439c77685eca6|e8d439c77685eca6].

  <p>If this option is defined, then it must also be 
  defined when using the 'lemon' tool to generate a parse.c
  file. Because of this, this option may only be used when the library is built
  from source, not from the [amalgamation] or from the collection of
  pre-packaged C files provided for non-Unix like platforms on the website.
  </p>
}

















COMPILE_OPTION {SQLITE_ENABLE_UNLOCK_NOTIFY} {
  This option enables the [sqlite3_unlock_notify()] interface and
  its associated functionality.  See the documentation titled
  [Using the SQLite Unlock Notification Feature] for additional
  information.

COMPILE_OPTION {SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION} {
  When the SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option is
  activated, SQLite will suppress "unknown function" errors when running
  an [EXPLAIN] or [EXPLAIN QUERY PLAN].  Instead of throwing an error,
  SQLite will insert a substitute no-op function named "unknown()".
  The substitution of "unknown()" in place of unrecognized functions
  only occurs on [EXPLAIN] and [EXPLAIN QUERY PLAN], not on ordinary
  statements.
  <p>
  When used in the [command-line shell], the
  SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION feature allows SQL text that contains
  application-defined functions to be pasted into the shell for 
  analysis and debugging without having to create and load an
  extension that implements the application-defined functions.
}

COMPILE_OPTION {SQLITE_ENABLE_UNLOCK_NOTIFY} {
  This option enables the [sqlite3_unlock_notify()] interface and
  its associated functionality.  See the documentation titled
  [Using the SQLite Unlock Notification Feature] for additional
  information.
