<li>Enhancements to [PRAGMA integrity_check] and [PRAGMA quick_check] so that
    they can optionally check just a single attached database install of all
    attached databases.
<li>Enhancements to [WAL mode] processing that ensure that at least one
    valid read-mark is available at all times, so that read-only processes
    can always read the database.
<li>Performance enhancements in the sorter used by ORDER BY and CREATE INDEX.
<li>Added the [SQLITE_DISABLE_FTS4_DEFERRED] compile-time option.

<li>[in-memory database | In-memory databases] that are specified using
    [URI filenames] are allowed to use [in-memory shared-cache | shared cache],
    so that the same
    in-memory database can be accessed from multiple database connections.

COMPILE_OPTION {SQLITE_DISABLE_FTS3_UNICODE} {
  If this C-preprocessor macro is defined, the [unicode61] tokenizer
  in [FTS3] is omitted from the build and is unavailable to 
  applications.
}

COMPILE_OPTION {SQLITE_DISABLE_FTS4_DEFERRED} {
  If this C-preprocessor macro disables the "deferred token" optimization
  in [FTS4].  The "deferred token" optimization avoids loading massive
  posting lists for terms that are in most documents of the collection
  and instead simply scans for those tokens in the document source.  [FTS4]
  should get exactly the same answer both with and without this optimization.
