Features include: </p> <p><ul> <li>Transactions are atomic, consistent, isolated, and durable (ACID) even after system crashes and power failures. <li>Zero-configuration - no setup or administration needed.</li> <li>Implements most of SQL92. (<a href="omitted.html">Features not supported</a>)</li> <li>A complete database is stored in a single disk file.</li> <li>Database files can be freely shared between machines with different byte orders.</li> <li>Supports databases up to 2 terabytes (2<sup><small>41</small></sup> bytes) in size.</li> <li>Sizes of strings and BLOBs limited only by available memory.</li> <li>Small code footprint: less than 250KiB fully configured or less than 150KiB with optional features omitted.</li> <li><a href="speed.html">Faster</a> than popular client/server database engines for most common operations.</li> <li>Simple, easy to use <a href="capi3.html">API</a>.</li> <li><a href="tclsqlite.html">TCL bindings</a> included. Bindings for many other languages <a href="http://www.sqlite.org/cvstrac/wiki?p=SqliteWrappers"> available separately.</a></li> <li>Well-commented source code with over 95% test coverage.</li> <li>Self-contained: no external dependencies.</li> <li>Sources are in the <a href="copyright.html">public domain</a>. Use for any purpose.</li> </ul> </p> <p> The SQLite distribution comes with a standalone command-line access program (<a href="sqlite.html">sqlite</a>) that can be used to administer an SQLite database and which serves as an example of how to use the SQLite library. </p> </td> <td width="1" bgcolor="#80a796"></td> <td valign="top" width="50%"> <h2>News</h2> <h3>2006-Jun-6 - Version 3.3.6</h3> <p> 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. </p> <hr width="50%"> <h3>2006-Apr-5 - Version 3.3.5</h3> <p> 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. </p> <hr width="50%"> <h3>2006-Feb-11 - Version 3.3.4</h3> <p> 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. </p> <hr width="50%"> <h3>2006-Jan-31 - Version 3.3.3 stable</h3> <p> 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. </p> <hr width="50%"> <h3>2006-Jan-24 - Version 3.3.2 beta</h3> <p> More bug fixes and performance improvements as we move closer to a production-ready version 3.3.x. </p> <hr width="50%"> <h3>2006-Jan-16 - Version 3.3.1 alpha</h3> <p> Many bugs found in last week's alpha release have now been fixed and the library is running much faster again.</p> <p> 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. </p> <hr width="50%"> <h3>2006-Jan-10 - Version 3.3.0 alpha</h3> <p> 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.</p> <p> The file format for version 3.3.0 has changed slightly in order provide a more efficient encoding of binary 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. </p> <hr width="50%"> <h3>2005-Dec-19 - Versions 3.2.8 and 2.8.17</h3> <p> 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. </p> <hr width="50%"> <p align="right"><a href="oldnews.html">Old news...</a></p> </td></tr></table> <table width="100%"> <tr><td bgcolor="#80a796"></td></tr> </table> <small><i>This page last modified on 2006/06/06 12:38:51</i></small> </body></html>
