newsitem {2014-03-08} {Release 3.8.4} {
<p>SQLite [version 3.8.4] is a maintenance release featuring performance
   enhancements and fixes for a number of obscure bugs.
   There are no significant new features in SQLite version 3.8.4.
   However, the number of CPU cycles (measured by valgrind) needed to 
   do many common operations has be reduced by about 12% relative to the
   previous release, and by about 25% relative to [version 3.7.16]
   from approximately one year ago.

<p>Version 3.8.4 of SQLite fixes several corner-case bugs that were
   found since the previous release.  These bugs were unlikely to appear
   in practice, and none represent a security vulnerability. 
   Nevertheless, developers are encouraged to upgrade from all prior releases.
