chng {2011 February 02 (3.7.5)} {
<li> Added the [sqlite3_vsnprintf()] interface.
<li> Added the [SQLITE_DBSTATUS_LOOKASIDE_HIT],
     [SQLITE_DBSTATUS_LOOKASIDE_MISS_SIZE], and
     [SQLITE_DBSTATUS_LOOKASIDE_MISS_FULL] options for the
     [sqlite3_db_status()] interface.
<li> Added the [SQLITE_OMIT_AUTORESET] compile-time option.
<li> Added the [SQLITE_DEFAULT_FOREIGN_KEYS] compile-time option.
<li> Updates to [sqlite3_stmt_readonly()] so that its result is well-defined
     for all prepared statements and so that it works with [VACUUM].
<li> Added the "-heap" option to the [command-line shell]
<li> Fix [http://www.sqlite.org/src/info/5d863f876e | a bug] involving
     frequent changes in and out of WAL mode and
     VACUUM that could (in theory) cause database corruption.
}

chng {2010 December 08 (3.7.4)} {
<li> Added the [sqlite3_blob_reopen()] interface to allow an existing
     [sqlite3_blob] object to be rebound to a new row.
<li> Use the new [sqlite3_blob_reopen()] interface to improve the performance
     of FTS.
<li> [sqlite3_vfs | VFSes] that do not support shared memory are allowed

  The overhead of invoking [sqlite3_initialize()] automatically in this
  way may be omitted by building SQLite with the SQLITE_OMIT_AUTOINIT
  C-preprocessor macro.  When built using SQLITE_OMIT_AUTOINIT, SQLite
  will not automatically initialize itself and the application is required
  to invoke [sqlite3_initialize()] directly prior to beginning use of the
  SQLite library.
}

COMPILE_OPTION {SQLITE_OMIT_AUTORESET} {
  By default, the [sqlite3_step()] interface will automatically invoke
  [sqlite3_reset()] to reset the [prepared statement] if necessary.  This
  compile-time option changes that behavior so that [sqlite3_step()] will
  return [SQLITE_MISUSE] if it called again after returning anything other
  than [SQLITE_ROW], [SQLITE_BUSY], or [SQLITE_LOCKED] unless there was an
  intervening call to [sqlite3_reset()].

  In SQLite version 3.6.23.1 and earlier, [sqlite3_step()] used to always
  return [SQLITE_MISUSE] if it was invoked again after returning anything
  other than [SQLITE_ROW] without an intervening call to [sqlite3_reset()].
  This caused problems on some poorly written smartphone applications which
  did not correctly handle the [SQLITE_LOCKED] and [SQLITE_BUSY] error 
  returns.  Rather than fix the many defective smartphone applications, 
  the behavior of SQLite was changed in 3.6.23.2 to automatically reset
  the prepared statement.  But that changed caused issues in other 
  improperly implemented applications that were actually looking
  for an [SQLITE_MISUSE] return to terminate their query loops.  (Anytime
  an application gets an SQLITE_MISUSE error code from SQLite, that means the
  application is misusing the SQLite interface and is thus incorrectly
  implemented.)  The SQLITE_OMIT_AUTORESET interface was added to SQLite
  version 3.7.5 in an effort to get all of the (broken)
  applications to work again without having to actually fix the applications.
}

COMPILE_OPTION {SQLITE_OMIT_AUTOVACUUM} {
  If this option is defined, the library cannot create or write to 
  databases that support [auto_vacuum].
  Executing a [PRAGMA auto_vacuum] statement is not an error
  (since unknown PRAGMAs are silently ignored), but does not return a value
  or modify the auto-vacuum flag in the database file. If a database that
