SQLite version 3.5.5 is now available for download from the SQLite website:
http://www.sqlite.org/ The big change from version 3.5.4 is that the internal virtual machine was reworked to use operands in registers rather than pulling operands from a stack. The virtual machine stack has now been removed. The removal of the VM stack will help prevent future stack overflow bugs and will also facilitate new optimizations in future releases. There should be no user-visible changes to the operation of SQLite in this release, except that the output of EXPLAIN looks different. In order to make this change, about 8.5% of the core SQLite code had to be reworked. We thought this might introduce instability. But we have done two weeks of intensive testing, during which time we have increased the statement test coverage to 99% and during which we have found and fixed lots of minor bugs (mostly things like leaking memory following a malloc failure). But for all of that testing, we have not detected a single bug in the new register-based VM. And for that reason, we believe the new VM, and hence version 3.5.5, is stable and ready for production use. As usual, please report any problems to this mailing list, or directly to me. -- D.
