SQLite Release 3.7.3 On 2010 October 08 (3.7.3)

Changes associated with this release include the following:

    * Added the sqlite3_create_function_v2() interface that includes a
      destructor callback.
    * Added support for custom r-tree queries using
      application-supplied callback routines to define the boundary of
      the query region.
    * The default page cache strives more diligently to avoid using
      memory beyond what is allocated to it by SQLITE_CONFIG_PAGECACHE.
      Or if using page cache is allocating from the heap, it strives to
      avoid going over the sqlite3_soft_heap_limit64(), even if
      SQLITE_ENABLE_MEMORY_MANAGEMENT is not set.
    * Added the sqlite3_soft_heap_limit64() interface as a replacement
      for sqlite3_soft_heap_limit().
    * The ANALYZE command now gathers statistics on tables even if they
      have no indices.
    * Tweaks to the query planner to help it do a better job of finding
      the most efficient query plan for each query.
    * Enhanced the internal text-to-numeric conversion routines so that
      they work with UTF8 or UTF16, thereby avoiding some UTF16-to-UTF8
      text conversions.
    * Fix a problem that was causing excess memory usage with large WAL
      transactions in win32 systems.
    * The interface between the VDBE and B-Tree layer is enhanced such
      that the VDBE provides hints to the B-Tree layer letting the
      B-Tree layer know when it is safe to use hashing instead of
      B-Trees for transient tables.
    * Miscellaneous documentation enhancements.
