SQLite Release 3.5.7 On 2008 Mar 17 (3.5.7)

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