  This release also adds explicit <a href="limits.html">limits</a> on the

  This release fixes two separate bugs either of which 
  can lead to database corruption.  Upgrading
  is strongly recommended.  If you must continue using an older version
  of SQLite, please at least read about how to avoid these bugs
  at
  <a href="http://www.sqlite.org/cvstrac/wiki?p=CorruptionFollowingBusyError">

  CorruptionFollowingBusyError</a> and

  <p>
  This release also adds explicit <a href="limits.html">limits</a> on the
  sizes and quantities of things SQLite will handle.  The new limits might
  causes compatibility problems for existing applications that
  use excessively large strings, BLOBs, tables, or SQL statements. 
  The new limits can be increased at compile-time to work around any problems
  that arise.  Nevertheless, the version number of this release is
  3.4.0 instead of 3.3.18 in order to call attention to the possible
  incompatibility.

Note that the transaction processing in SQLite requires two bits
of heap memory for every page in the database file.  For databases
of a few megabytes in size, this amounts to only a few hundred
bytes of heap memory.  But for gigabyte-sized database the amount
of heap memory required is getting into the kilobyte range and
for terabyte-sized databases, megabytes of heap memory must be
allocated and zeroed at each transaction.  SQLite will
support very large databases in theory, but the current implementation
is optimized for the common SQLite use cases of embedded devices
and persistent stores for desktop applications.  In other words,
SQLite is designed for use with databases sized in kilobytes or
