newsitem {2007-Jun-18} {Version 3.4.0} {
This release fixes two separate bugs either of which
can lead to database corruption. Upgrading
is strongly recommended. If you must continue using an older version
of SQLite, please at least read about how to avoid these bugs
at
<a href="http://www.sqlite.org/cvstrac/wiki?p=CorruptionFollowingBusyError">
CorruptionFollowingBusyError</a> and
<a href="http://www.sqlite.org/cvstrac/tktview?tn=2418">ticket #2418</a>
<p>
This release also adds explicit <a href="limits.html">limits</a> on the
sizes and quantities of things SQLite will handle. The new limits might
causes compatibility problems for existing applications that
use excessively large strings, BLOBs, tables, or SQL statements.
The new limits can be increased at compile-time to work around any problems
that arise. Nevertheless, the version number of this release is
3.4.0 instead of 3.3.18 in order to call attention to the possible
incompatibility.
</p>
There are also new features, including
<a href="capi3ref.html#sqlite3_blob_open">incremental BLOB I/O</a> and
<a href="pragma.html#pragma_incremental_vacuum">incremental vacuum</a>.
See the <a href="changes.html#version_3_4_0">change log</a>
for additional information.
}
newsitem {2007-Apr-25} {Version 3.3.17} {
This version fixes a bug in the forwards-compatibility logic of SQLite
that was causing a database to become unreadable when it should have
been read-only. Upgrade from 3.3.16 only if you plan to deploy into
a product that might need to be upgraded in the future. For day to day
use, it probably does not matter.
}
newsitem {2007-Apr-18} {Version 3.3.16} {
Performance improvements added in 3.3.14 but mistakenly turned off
in 3.3.15 have been reinstated. A bug has been fixed that prevented
VACUUM from running if a NULL value was in a UNIQUE column.
}
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.

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!
Version 3.2.0 also fixes an obscure but serious bug that was discovered
just prior to release. If you have a multi-statement transaction and
within that transaction an UPDATE or INSERT statement fails due to a
constraint, then you try to rollback the whole transaction, the rollback
might not work correctly. See
<a href="http://www.sqlite.org/cvstrac/tktview?tn=1171">Ticket #1171</a>
for details. Upgrading is recommended for all users.
}
newsitem {2005-Mar-16} {Version 3.1.6} {
Version 3.1.6 fixes a critical bug that can cause database corruption
when inserting rows into tables with around 125 columns. This bug was
introduced in version 3.0.0. See
<a href="http://www.sqlite.org/cvstrac/tktview?tn=1163">Ticket #1163</a>
for additional information.
}
newsitem {2005-Mar-11} {Versions 3.1.4 and 3.1.5 Released} {
Version 3.1.4 fixes a critical bug that could cause database corruption
if the autovacuum mode of version 3.1.0 is turned on (it is off by
default) and a CREATE UNIQUE INDEX is executed within a transaction but
fails because the indexed columns are not unique. Anyone using the
autovacuum feature and unique indices should upgrade.
Version 3.1.5 adds the ability to disable
the F_FULLFSYNC ioctl() in OS-X by setting "PRAGMA synchronous=on" instead
of the default "PRAGMA synchronous=full". There was an attempt to add
this capability in 3.1.4 but it did not work due to a spelling error.
}
newsitem {2005-Feb-19} {Version 3.1.3 Released} {
Version 3.1.3 cleans up some minor issues discovered in version 3.1.2.
}
newsitem {2005-Feb-15} {Versions 2.8.16 and 3.1.2 Released} {
A critical bug in the VACUUM command that can lead to database
corruption has been fixed in both the 2.x branch and the main
3.x line. This bug has existed in all prior versions of SQLite.
Even though it is unlikely you will ever encounter this bug,
it is suggested that all users upgrade. See
<a href="http://www.sqlite.org/cvstrac/tktview?tn=1116">
ticket #1116</a>. for additional information.
Version 3.1.2 is also the first stable release of the 3.1
series. SQLite 3.1 features added support for correlated
subqueries, autovacuum, autoincrement, ALTER TABLE, and
other enhancements. See the
<a href="http://www.sqlite.org/releasenotes310.html">release notes

The first alpha release of SQLite version 3.0 is available for
public review and comment. Version 3.0 enhances internationalization support
through the use of UTF-16 and user-defined text collating sequences.
BLOBs can now be stored directly, without encoding.
A new file format results in databases that are 25% smaller (depending
on content). The code is also a little faster. In spite of the many
new features, the library footprint is still less than 240KB
(x86, gcc -O1).
<a href="version3.html">Additional information</a>.
Our intent is to freeze the file format and API on 2004-Jul-01.
