SQLite Release 3.3.9 On 2007-01-04#

1. Fix bugs in pager.c that could lead to database corruption if two processes both try to recover a hot journal at the same instant
2. Added the sqlite3_prepare_v2() API.

   1. Optimizer does a better job of using indices to satisfy ORDER BY clauses that sort on the integer primary key
   2. Use an index to satisfy an IS NULL operator in the WHERE clause

   4. The optimizer has more freedom to reorder tables in the FROM clause even in there are LEFT joins.
7. Extension loading supported added to WinCE

9. Added the ".bail" command to the command-line shell
