1. Fix a bug (ticket #2927) in the register allocation for compound selects - introduced by the new VM code in version 3.5.5.
2. ALTER TABLE uses double-quotes instead of single-quotes for quoting filenames.
3. Use the WHERE clause to reduce the size of a materialized VIEW in an UPDATE or DELETE statement. (Optimization)
4. Do not apply the flattening optimization if the outer query is an aggregate and the inner query contains ORDER BY. (Ticket #2943)
5. Additional OS/2 updates
6. Added an experimental power-of-two, first-fit memory allocator.
7. Remove all instances of sprintf() from the code
8. Accept "Z" as the zulu timezone at the end of date strings
9. Fix a bug in the LIKE optimizer that occurs when the last character before the first wildcard is an upper-case "Z"
10. Added the "bitvec" object for keeping track of which pages have been journalled. Improves speed and reduces memory consumption, especially for large database files.
11. Get the SQLITE_ENABLE_LOCKING_STYLE macro working again on Mac OS X.
12. Store the statement journal in the temporary file directory instead of collocated with the database file.
13. Many improvements and cleanups to the configure script
