This release also creates new public interfaces: <a href="c3ref/randomness.html">sqlite3_randomness()</a> provides access to SQLite's internal pseudo-random number generator, <a href="c3ref/limit.html">sqlite3_limit()</a> allows size limits to be set at run-time on a per-connection basis, and <a href="c3ref/context_db_handle.html">sqlite3_context_db_handle()</a> is a convenience routine that allows an application-defined SQL function implementation to retrieve its <a href="c3ref/sqlite3.html">database connection</a> handle.</p><p> This release of SQLite is considered stable and ready for production use.</p><hr width="50%"><a name="2008_mar_17"></a><h3>2008-Mar-17 - Version 3.5.7</h3><p> Version 3.5.7 fixes several minor and obscure bugs, especially in the autoconf-generated makefile. Upgrading is optional. This release of SQLite is considered stable and ready for production use.</p><hr width="50%"><a name="2008_feb_6"></a><h3>2008-Feb-6 - Version 3.5.6</h3><p> Version 3.5.6 fixes a minor regression in 3.5.5 - a regression that had nothing to do with the massive change ove the virtual machine to a register-based design. No problems have been reported with the new virtual machine. This release of SQLite is considered stable and ready for production use.</p><hr width="50%"><a name="2008_jan_31"></a><h3>2008-Jan-31 - Version 3.5.5</h3><p> Version 3.5.5 changes over 8% of the core source code of SQLite in order to convert the internal virtual machine from a stack-based design into a register-based design. This change will allow future optimizations and will avoid an entire class of stack overflow bugs that have caused problems in the past. Even though this change is large, extensive testing has found zero errors in the new virtual machine and so we believe this to be a very stable release.</p><hr width="50%"><a name="2007_dec_14"></a><h3>2007-Dec-14 - Version 3.5.4</h3><p> Version 3.5.4 fixes an long-standing but obscure bug in UPDATE and DELETE which might cause database corruption. (See <a href="http://www.sqlite.org/cvstrac/tktview?tn=2832">ticket #2832</a>.) Upgrading is recommended for all users.</p><p> This release also brings the processing of ORDER BY statements into compliance with standard SQL. This could, in theory, cause problems for existing applications that depend on the older, buggy behavior. See <a href="http://www.sqlite.org/cvstrac/tktview?tn=2822">ticket #2822</a> for additional information.</p><hr width="50%"><a name="2007_dec_12"></a><h3>2007-Dec-12 - SQLite Consortium Announced</h3><p> The <a href="consortium.html">SQLite Consortium</a> was launched today with <a href="http://www.mozilla.org/">Mozilla</a> and <a href="http://www.symbian.com/">Symbian</a> as charter members. As noted in the <a href="pressrelease-20071212.html">press release</a>, the Consortium's goal is to promote the continuing vitality and independence of SQLite. </p><hr width="50%"><a name="2007_nov_27"></a><h3>2007-Nov-27 - Version 3.5.3</h3><p> This is an incremental release that fixes several minor problems. Upgrading is optional. If Version 3.5.2 or 3.5.1 is working fine for you, then there is no pressing need to change to 3.5.3.</p><p> The prebuilt binaries and the amalgamation found on the <a href="download.html">download</a> page include the FTS3 fulltext search extension module. We are doing this on an experimental basis and are not promising to provide prebuilt binaries with FTS3 in the future.</p><hr width="50%"><a href="oldnews.html">Old news...</a><hr><small><i>This page last modified 2008/04/16 15:05:54 UTC</i></small></div></body></html>⌨️ 快捷键说明
