newsitem {2007-Apr-09} {Version 3.3.15} {
  An annoying bug introduced in 3.3.14 has been fixed.  There are
  also many enhancements to the test suite.  
}

newsitem {2007-Apr-02} {Version 3.3.14} {
  This version focuses on performance improvements.  If you recompile
  <a href="http://www.sqlite.org/cvstrac/wiki?p=TheAmalgamation">
  the amalgamation</a> using GCC option -O3 (the precompiled binaries
  use -O2) you may see performance
  improvements of 35% or more over version 3.3.13 depending on your
  workload.  This version also
  adds support for <a href="pragma.html#pragma_locking_mode">
  exclusive access mode</a>.
}

newsitem {2007-Feb-13} {Version 3.3.13} {
  This version fixes a subtle bug in the ORDER BY optimizer that can 
  occur when using joins.  There are also a few minor enhancements.
  Upgrading is recommended.
}

newsitem {2007-Jan-27} {Version 3.3.12} {
  The first published build of the previous version used the wrong
  set of source files.  Consequently, many people downloaded a build
  that was labeled as "3.3.11" but was really 3.3.10.  Version 3.3.12
  is released to clear up the ambiguity.  A couple more bugs have
  also been fixed and <a href="pragma.html#pragma_integrity_check">
  PRAGMA integrity_check</a> has been enhanced.
}

newsitem {2007-Jan-22} {Version 3.3.11} {
  Version 3.3.11 fixes for a few more problems in version 3.3.9 that
  version 3.3.10 failed to catch.  Upgrading is recommended.
}

newsitem {2007-Jan-9} {Version 3.3.10} {
  Version 3.3.10 fixes several bugs that were introduced by the previous
  release.  Upgrading is recommended.
}

newsitem {2007-Jan-4} {Version 3.3.9} {
  Version 3.3.9 fixes bugs that can lead to database corruption under
  obscure and difficult to reproduce circumstances.  See
  <a href="http://www.sqlite.org/cvstrac/wiki?p=DatabaseCorruption">
  DatabaseCorruption</a> in the
  <a href="http://www.sqlite.org/cvstrac/wiki">wiki</a> for details.
  This release also adds the new
  <a href="capi3ref.html#sqlite3_prepare_v2">sqlite3_prepare_v2()</a>
  API and includes important bug fixes in the command-line
  shell and enhancements to the query optimizer.  Upgrading is
  recommended.
}

newsitem {2006-Oct-9} {Version 3.3.8} {
  Version 3.3.8 adds support for full-text search using the 
  <a href="http://www.sqlite.org/cvstrac/wiki?p=FtsOne">FTS1
  module.</a>  There are also minor bug fixes.  Upgrade only if
  you want to try out the new full-text search capabilities or if
  you are having problems with 3.3.7.
}

newsitem {2006-Aug-12} {Version 3.3.7} {
  Version 3.3.7 includes support for loadable extensions and virtual
  tables.  But both features are still considered "beta" and their
  APIs are subject to change in a future release.  This release is
  mostly to make available the minor bug fixes that have accumulated
  since 3.3.6.  Upgrading is not necessary.  Do so only if you encounter
  one of the obscure bugs that have been fixed or if you want to try
  out the new features.
}

newsitem {2006-Jun-19} {New Book About SQLite} {
  <a href="http://www.apress.com/book/bookDisplay.html?bID=10130">
  <i>The Definitive Guide to SQLite</i></a>, a new book by
  <a href="http://www.mikesclutter.com">Mike Owens</a>.
  is now available from <a href="http://www.apress.com">Apress</a>.
  The books covers the latest SQLite internals as well as
  the native C interface and bindings for PHP, Python,
  Perl, Ruby, Tcl, and Java.  Recommended.
}


newsitem {2006-Jun-6} {Version 3.3.6} {
  Changes include improved tolerance for windows virus scanners
  and faster :memory: databases.  There are also fixes for several
  obscure bugs.  Upgrade if you are having problems.
}

newsitem {2006-Apr-5} {Version 3.3.5} {
  This release fixes many minor bugs and documentation typos and
  provides some minor new features and performance enhancements.
  Upgrade only if you are having problems or need one of the new features.
}

newsitem {2006-Feb-11} {Version 3.3.4} {
  This release fixes several bugs, including a 
  a blunder that might cause a deadlock on multithreaded systems.
  Anyone using SQLite in a multithreaded environment should probably upgrade.
}

newsitem {2006-Jan-31} {Version 3.3.3 stable} {
  There have been no major problems discovered in version 3.3.2, so
  we hereby declare the new APIs and language features to be stable
  and supported.
}

newsitem {2006-Jan-24} {Version 3.3.2 beta} {
  More bug fixes and performance improvements as we move closer to
  a production-ready version 3.3.x.
}

newsitem {2006-Jan-16} {Version 3.3.1 alpha} {
  Many bugs found in last week's alpha release have now been fixed and
  the library is running much faster again.

  Database connections can now be moved between threads as long as the
  connection holds no locks at the time it is moved.  Thus the common
  paradigm of maintaining a pool of database connections and handing
  them off to transient worker threads is now supported.
  Please help test this new feature.
  See <a href="http://www.sqlite.org/cvstrac/wiki?p=MultiThreading">
  the MultiThreading wiki page</a> for additional
  information.
}

newsitem {2006-Jan-10} {Version 3.3.0 alpha} {
  Version 3.3.0 adds support for CHECK constraints, DESC indices,
  separate REAL and INTEGER column affinities, a new OS interface layer
  design, and many other changes.  The code passed a regression
  test but should still be considered alpha.  Please report any
  problems.

  The file format for version 3.3.0 has changed slightly to support
  descending indices and
  a more efficient encoding of boolean values.  SQLite 3.3.0 will read and
  write legacy databases created with any prior version of SQLite 3.  But
  databases created by version 3.3.0 will not be readable or writable
  by earlier versions of the SQLite.  The older file format can be
  specified at compile-time for those rare cases where it is needed.
}

newsitem {2005-Dec-19} {Versions 3.2.8 and 2.8.17} {
  These versions contain one-line changes to 3.2.7 and 2.8.16 to fix a bug
  that has been present since March of 2002 and version 2.4.0.
  That bug might possibly cause database corruption if a large INSERT or
  UPDATE statement within a multi-statement transaction fails due to a
  uniqueness constraint but the containing transaction commits.
}


newsitem {2005-Sep-24} {Version 3.2.7} {
  This version fixes several minor and obscure bugs.
  Upgrade only if you are having problems.
}

newsitem {2005-Sep-16} {Version 3.2.6 - Critical Bug Fix} {
  This version fixes a bug that can result in database
  corruption if a VACUUM of a 1 gibibyte or larger database fails
  (perhaps do to running out of disk space or an unexpected power loss)
  and is later rolled back.
  <p>
  Also in this release:
  The ORDER BY and GROUP BY processing was rewritten to use less memory.
  Support for COUNT(DISTINCT) was added.  The LIKE operator can now be
  used by the optimizer on columns with COLLATE NOCASE.
}

newsitem {2005-Aug-27} {Version 3.2.5} {
  This release fixes a few more lingering bugs in the new code.
  We expect that this release will be stable and ready for production use.
}

newsitem {2005-Aug-24} {Version 3.2.4} {
  This release fixes a bug in the new optimizer that can lead to segfaults
  when parsing very complex WHERE clauses.
}

newsitem {2005-Aug-21} {Version 3.2.3} {
  This release adds the <a href="lang_analyze.html">ANALYZE</a> command,
  the <a href="lang_expr.html">CAST</a> operator, and many
  very substantial improvements to the query optimizer.  See the
  <a href="changes.html#version_3_2_3">change log</a> for additional
  information.
}

newsitem {2005-Aug-2} {2005 Open Source Award for SQLite} {
  SQLite and its primary author D. Richard Hipp have been honored with
  a <a href="http://osdir.com/Article6677.phtml">2005 Open Source
  Award</a> from Google and O'Reilly.<br clear="right">
}


newsitem {2005-Jun-13} {Version 3.2.2} {
  This release includes numerous minor bug fixes, speed improvements,
  and code size reductions.  There is no reason to upgrade unless you
  are having problems or unless you just want to.
}

newsitem {2005-Mar-29} {Version 3.2.1} {
  This release fixes a memory allocation problem in the new
  <a href="lang_altertable.html">ALTER TABLE ADD COLUMN</a>
  command.
}

newsitem {2005-Mar-21} {Version 3.2.0} {
  The primary purpose for version 3.2.0 is to add support for
  <a href="lang_altertable.html">ALTER TABLE ADD COLUMN</a>.
  The new ADD COLUMN capability is made
  possible by AOL developers supporting and embracing great
  open-source software.  Thanks, AOL!
