The library is now in the    public domain.</li>}chng {2001 Jul 23 (1.0.32)} {<li>Pager and btree subsystems removed.  These will be used in a follow-on    SQL server library named "SQLus".</li><li>Add the ability to use quoted strings as table and column names in    expressions.</li>}chng {2001 Apr 14 (1.0.31)} {<li>Pager subsystem added but not yet used.</li><li>More robust handling of out-of-memory errors.</li><li>New tests added to the test suite.</li>}chng {2001 Apr 6 (1.0.30)} {<li>Remove the <b>sqlite_encoding</b> TCL variable that was introduced    in the previous version.</li><li>Add options <b>-encoding</b> and <b>-tcl-uses-utf</b> to the    <b>sqlite</b> TCL command.</li><li>Add tests to make sure that tclsqlite was compiled using Tcl header    files and libraries that match.</li>}chng {2001 Apr 5 (1.0.29)} {<li>The library now assumes data is stored as UTF-8 if the --enable-utf8    option is given to configure.  The default behavior is to assume    iso8859-x, as it has always done.  This only makes a difference for    LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li><li>If the library is not configured for UTF-8 and the Tcl library    is one of the newer ones that uses UTF-8 internally,    then a conversion from UTF-8 to iso8859 and    back again is done inside the TCL interface.</li>}chng {2001 Apr 4 (1.0.28)} {<li>Added limited support for transactions.  At this point, transactions    will do table locking on the GDBM backend.  There is no support (yet)    for rollback or atomic commit.</li><li>Added special column names ROWID, OID, and _ROWID_ that refer to the    unique random integer key associated with every row of every table.</li><li>Additional tests added to the regression suite to cover the new ROWID    feature and the TCL interface bugs mentioned below.</li><li>Changes to the "lemon" parser generator to help it work better when    compiled using MSVC.</li><li>Bug fixes in the TCL interface identified by Oleg Oleinick.</li>}chng {2001 Mar 20 (1.0.27)} {<li>When doing DELETE and UPDATE, the library used to write the record    numbers of records to be deleted or updated into a temporary file.    This is changed so that the record numbers are held in memory.</li><li>The DELETE command without a WHILE clause just removes the database    files from the disk, rather than going through and deleting record    by record.</li>}chng {2001 Mar 20 (1.0.26)} {<li>A serious bug fixed on Windows.  Windows users should upgrade.    No impact to Unix.</li>}chng {2001 Mar 15 (1.0.25)} {<li>Modify the test scripts to identify tests that depend on system    load and processor speed and    to warn the user that a failure of one of those (rare) tests does    not necessarily mean the library is malfunctioning.  No changes to    code.    </li>}chng {2001 Mar 14 (1.0.24)} {<li>Fix a bug which was causing    the UPDATE command to fail on systems where "malloc(0)" returns    NULL.

Fixed.</li>}chng {2001 Feb 11 (1.0.20)} {<li>Merge development changes into the main trunk.  Future work toward    using a BTree file structure will use a separate CVS source tree.  This    CVS tree will continue to support the GDBM version of SQLite only.</li>}chng {2001 Feb 6 (1.0.19)} {<li>Fix a strange (but valid) C declaration that was causing problems    for QNX.  No logical changes.</li>}chng {2001 Jan 4 (1.0.18)} {<li>Print the offending SQL statement when an error occurs.</li><li>Do not require commas between constraints in CREATE TABLE statements.</li><li>Added the "-echo" option to the shell.</li><li>Changes to comments.</li>}chng {2000 Dec 10 (1.0.17)} {<li>Rewrote <b>sqlite_complete()</b> to make it faster.</li><li>Minor tweaks to other code to make it run a little faster.</li><li>Added new tests for <b>sqlite_complete()</b> and for memory leaks.</li>}chng {2000 Dec 4 (1.0.16)} {<li>Documentation updates.

This mistake has now been fixed.</li>}chng {2000 June 16} {<li>Added the concatenate string operator (||)</li>}chng {2000 June 12} {<li>Added the fcnt() function to the SQL interpreter.  The fcnt() function    returns the number of database "Fetch" operations that have occurred.    This function is designed for use in test scripts to verify that    queries are efficient and appropriately optimized.  Fcnt() has no other    useful purpose, as far as I know.</li><li>Added a bunch more tests that take advantage of the new fcnt() function.    The new tests did not uncover any new problems.</li>}chng {2000 June 8} {<li>Added lots of new test cases</li><li>Fix a few bugs discovered while adding test cases</li><li>Begin adding lots of new documentation</li>}chng {2000 June 6} {<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,<b>INTERSECT</b>, and <b>EXCEPT</b></li><li>Added support for using <b>(SELECT ...)</b> within expressions</li><li>Added support for <b>IN</b> and <b>BETWEEN</b> operators</li><li>Added support for <b>GROUP BY</b> and <b>HAVING</b></li><li>NULL values are now reported to the callback as a NULL pointer    rather than an empty string.</li>}chng {2000 June 3} {<li>Added support for default values on columns of a table.</li><li>Improved test coverage.  Fixed a few obscure bugs found by theimproved tests.</li>}chng {2000 June 2} {<li>All database files to be modified by an UPDATE, INSERT or DELETE are now locked before any changes are made to any files.  This makes it safe (I think) to accessthe same database simultaneously from multiple processes.</li><li>The code appears stable so we are now calling it "beta".</li>}chng {2000 June 1} {<li>Better support for file locking so that two or more processes (or threads)can access the same database simultaneously.  More work needed inthis area, though.</li>}chng {2000 May 31} {<li>Added support for aggregate functions (Ex: <b>COUNT(*)</b>, <b>MIN(...)</b>)to the SELECT statement.</li><li>Added support for <B>SELECT DISTINCT ...</B></li>}chng {2000 May 30} {<li>Added the <b>LIKE</b> operator.</li><li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B> but it uses Unix shell globbing wildcards instead of the '%' and '_' wildcards of SQL.</li><li>Added the <B>COPY</b> command patterned after <a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLitecan now read the output of the <b>pg_dump</b> database dump utilityof PostgreSQL.</li><li>Added a <B>VACUUM</B> command that that calls the <b>gdbm_reorganize()</b> function on the underlying databasefiles.</li><li>And many, many bug fixes...</li>}chng {2000 May 29} {<li>Initial Public Release of Alpha code</li>}puts {</DL>}footer {$Id:}
