    <p><b>1.0.77.0 - November XX, 2011</b></p>
    <ul>
      <li>Updated to SQLite 3.7.9 <a href="http://www.sqlite.org/src/info/c7c6050ef0">[c7c6050ef0]</a>.</li>
      <li>More enhancements to the build and test automation.</li>
      <li>Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for <a href="http://system.data.sqlite.org/index.html/info/566f1ad1e4">[566f1ad1e4]</a>.</li>
      <li>When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for <a href="http://system.data.sqlite.org/index.html/info/343d392b51">[343d392b51]</a>.</li>
      <li>Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for <a href="http://system.data.sqlite.org/index.html/info/343d392b51">[343d392b51]</a>.</li>
      <li>Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.</li>
      <li>Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for <a href="http://system.data.sqlite.org/index.html/info/737ca4ff74">[737ca4ff74]</a>.</li>
      <li>Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for <a href="http://system.data.sqlite.org/index.html/info/544dba0a2f">[544dba0a2f]</a>.</li>
      <li>Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for <a href="http://system.data.sqlite.org/index.html/info/84718e79fa">[84718e79fa]</a>.</li>
    </ul>
    <p><b>1.0.76.0 - October 4, 2011</b></p>
    <ul>
      <li>Prevent the domain unload event handler in SQLiteLog from being registered multiple times. Fix for <a href="http://system.data.sqlite.org/index.html/info/0d5b1ef362">[0d5b1ef362]</a>.</li>
      <li>Stop allowing non-default application domains to initialize the SQLiteLog class. Fix for <a href="http://system.data.sqlite.org/index.html/info/ac47dd230a">[ac47dd230a]</a>.</li>
    </ul>
    <p><b>1.0.75.0 - October 3, 2011</b></p>
    <ul>

    </ul>
    <p><b>1.0.65.0 - July 26, 2009</b></p>
    <ul>
      <li>Fixed a bug in the encryption module to prevent a double free() when rekeying a database.</li>
      <li>Fixed a bug in the encryption module when ATTACHing an encrypted database.</li>
      <li>Incorporated the WinCE locking fix from ticket
        <a href="http://www.sqlite.org/cvstrac/tktview?tn=3991">#3991</a></li>
      <li>Added &quot;bigint&quot; to the dropdown in the table designer, plus other minor table
        designer bugfixes.</li>
    </ul>
    <p><b>1.0.64.0 - July 9, 2009</b></p>
    <ul>
      <li>Fixed the missing resources problem from the 63 release.</li>
      <li>Added preliminary support for the Visual Studio 2010 beta.</li>
      <li>Fixed a bug in SQLiteCommand that threw a null reference exception when
        setting the Transaction object to null.</li>
      <li>If SQLiteConnection.EnlistTransaction is called multiple times for the same
        transaction scope, just return without throwing an error.</li>
    </ul>
    <p><b>1.0.63.0 - June 29, 2009</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.16</li>
      <li>Check the autocommit mode of the connection to which a transaction is bound
        during the disposal of the transaction.&nbsp; If autocommit is enabled, then the
        database has already rolled back the transaction and we don&#39;t need to do it
        during dispose, and can quietly ignore the step without throwing an error.</li>
      <li>Eliminated the mergebin step altogether.&nbsp; It was developed primarily to
        merge the Compact Framework binaries together, but since we&#39;re not doing that
        anymore, its use is limited.&nbsp; Its non-standard method of merging a binary
        on the desktop framework is redundant as well.&nbsp; The desktop binary now
        hard-links to MSCOREE, but as of Windows XP, this was redundant as well since XP
        and beyond automatically attempt to load MSCOREE on startup when a DLL has a
        .NET header.</li>
      <li>More improvements to the test.exe program for running the tests against Sql
        Server for comparison purposes.</li>
    </ul>
    <p><b>1.0.62.0 - June 20, 2009</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.15</li>
      <li>Fixed the decimal reading bug in the SQLiteDataReader</li>
      <li>Changed Join()&#39;s to Sleep()&#39;s in the statement retry code to prevent message
        pumping</li>
      <li>Fixed a bad pointer conversion when retrieving blobs using GetBytes() in
        64-bit land</li>
      <li>Several changes to the Test program that comes with the provider.&nbsp; Tests
        can now be individually disabled, and the test program can run against several
        provider back-ends</li>
    </ul>
    <p><b>1.0.61.0 - April 28, 2009</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.13.  The new backup features are as yet unimplemented in the provider, but will be forthcoming in a subsequent release</li>
      <li>Fixed the default-value lookups in SQLiteConnectionStringBuilder when accessing properties</li>
      <li>Lock the SQLiteTransaction object during dispose to avoid potential race condition during cleanup</li>
      <li>Fixed SQLiteDataReader.GetDecimal() processing and parsing of decimal values for cases when SQLite returns things like "1.0e-05" instead of "0.0001"</li>
    </ul>
    <p><b>1.0.60.0 - October 3, 2008</b></p>
    <ul>
      <li>Throw a NotSupported exception in the EF Sql Gen code instead of parsing
        illegal SQL during an update/insert/delete where no primary key is defined.</li>
      <li>Fixed the Compact Framework interop library.&nbsp; Since the linker flag
        /subsystem had no version specified, it was causing a problem for many CE-based
        platforms.</li>
      <li>Incorporated SQLite patch for ticket
        <a href="http://www.sqlite.org/cvstrac/tktview?tn=3387">#3387</a> and reverted
        out the vfs override code I added in build 59 to work around this problem.</li>
      <li>Fixed a designer issue when creating a new table from the Server Explorer.&nbsp;
        After initially saving it, if you then continued to edit it and tried to save it
        again, it would generate the change SQL using the old temporary table name
        rather than the new name.</li>
    </ul>
    <p><b>1.0.59.0 - September 22, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.3.&nbsp; Solves
        a couple different EF issues that were either giving inconsistent results or
        crashing the engine.</li>
      <li>Fixed the parsing of literal binaries in the EF SqlGen code.&nbsp; SQLite now
        passes nearly all the testcases in
        <a href="http://sqlite.phxsoftware.com/forums/p/1377/5921.aspx#5921">Microsoft's EF Query Samples</a> application --
        the exception being the <i>datetimeoffset </i>and<i> time</i> constants tests, and tests
        that use the <i>APPLY </i>keyword which are unsupported for now.</li>
      <li>Revamped the Compact Framework mixed-mode assembly.&nbsp; Tired of playing cat
        and mouse with the Compact Framework&#39;s support for mixed-mode assemblies.&nbsp;
        The CF build now requires that you distribute both the System.Data.SQLite
        library and the paired SQLite.Interop.XXX library.&nbsp;&nbsp; The XXX denotes
        the build number of the library.</li>
      <li>Implemented a workaround for Vista&#39;s overzealous caching by turning off
        FILE_FLAG_RANDOM_ACCESS for OS versions above XP.&nbsp; This is implemented
        as a custom (default override) VFS in the interop.c file, so no changes are made
        to the SQLite source code.</li>
      <li>Fixed some registry issues in the designer install.exe, which prevented some
        design-time stuff from working on the Compact Framework when .NET 3.5 was
        installed.</li>
    </ul>
    <p><b>1.0.58.0 - August 30, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.2.&nbsp; If only I&#39;d waited one more day to release
        57!&nbsp; Several LINQ issues have been resolved with this engine release
        relating to deeply-nested subqueries that the EF SqlGen creates.</li>
      <li>Fixed the Rollback SQLiteConnection event to not require a connection be
        opened first.</li>
    </ul>
    <p><b>1.0.57.0 - August 29, 2008</b></p>
    <ul>
      <li>Compiled against 3.6.1 with checkin
        <a href="http://www.sqlite.org/cvstrac/tktview?tn=3300">#3300</a> resolved,
        which fixes an Entity Framework bug I was seeing.&nbsp; I currently have 3 other
        tickets out on the engine, which are not yet resolved and relate to EF.</li>
      <li>Fixed decimal types to store and fetch using InvariantCulture.&nbsp; If you&#39;re
        using decimal datatypes in your database and were affected by the 56 release,
        please issue an UPDATE &lt;table&gt; SET &lt;column&gt; = REPLACE(&lt;column&gt;, &#39;,&#39;, &#39;.&#39;);&nbsp;
        to fix the decimal separators.&nbsp; Apologies for not testing that more
        thoroughly before releasing 56.</li>
      <li>Too many LINQ fixes to list.&nbsp; Fixed views so they generate,
        fixed the LIMIT clause, implemented additional functionality and removed unnecessary code.</li>
      <li>Fixed foreign key names in the designer so viewing the SQL script on a new
        unsaved table after renaming it in the properties toolwindow will reflect in the
        script properly.</li>
      <li>Fixed the Update and Commit events on SQLiteConnection so they don&#39;t require
        the connection to be opened first.</li>
      <li>Fixed userdef aggregate functions so they play nice with each other when
        appearing multiple times in the same statement.</li>
      <li>Fixed the editing and saving of default values in the table designer.</li>
      <li>Fixed ForeignKeys schema to support multi-column foreign keys.&nbsp; Also
        hacked support for them in the table designer, provided two foreign keys in the
        designer have the same name and reference the same foreign table and different
        columns.&nbsp; Will implement first-class support for this in the next release.</li>
    </ul>
    <p><b>1.0.56.0 - August 11, 2008</b></p>
    <ul>
      <li>Fixed a bug in the table designer when designing new tables, wherein you had to
        save the table first before being able to create indexes and foreign keys.</li>
      <li>Tweaks to decimal type handling.&nbsp; The &#39;decimal&#39; type can&#39;t be represented
        by Int64 or Double (without loss of precision) in SQLite, so we have to fudge it
        by treating it like a string and converting it back and forth in the provider.&nbsp;
        Unfortunately backing it to the db as a string causes sorting problems.&nbsp;
        See <a href="http://sqlite.phxsoftware.com/forums/p/1296/5595.aspx#5595">this
        post</a>
        for details on using a custom collation sequence to overcome the sorting issue arising from this patch.</li>
      <li>Minor tweaks and bugfixes to the test program and the provider.</li>
      <li>More adjustments to make the managed-only version of the provider run and pass
        all tests on Mono.</li>
      <li>LINQ to Entities bits heavily updated and compiled against VS2008 SP1 RTM.&nbsp; SQLite
        LINQ support is still considered beta.</li>
    </ul>
    <p><b>1.0.55.0 - August 6, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.1</li>
      <li>Added support for the user-contributed extension-functions at
        <a href="http://www.sqlite.org/contrib">http://www.sqlite.org/contrib</a>.&nbsp;
        Feel free to override any of them with your own implementation.&nbsp; The new
        functions are: <i>acos, asin, atan, atn2, atan2, acosh, asinh, atanh,
        difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp,
        log, log10, power, sign, sqrt, square, ceil, floor, pi, replicate, charindex,
        leftstr, rightstr, reverse, proper, padl, padr, padc, strfilter,</i> and
        aggregates <i>stdev, variance, mode, median, lower_quartile, upper_quartile.</i></li>
      <li>Moved the last_rows_affected() function to the C extension library.</li>
      <li>Added a new class, SQLiteFunctionEx which extends SQLiteFunction and adds the
        ability for a user-defined function to get the collating sequence during the
        Invoke/Step methods.&nbsp; User-defined functions can use the collating sequence
        as a helper to compare values.</li>
      <li>When registering user-defined collation sequences and functions, the provider
        will now register both a UTF8 and a UTF16 version instead of just UTF8.</li>
      <li>Revamped connection pooling and added static ClearPool() and ClearAllPools()
        functions to SQLiteConnection.&nbsp; Behavior of the pool and its clearing
        mechanics match SqlClient.</li>
      <li>Fixed connections going to the pool so that any unfinalized lingering commands
        from un-collected datareaders are automatically reset and any lurking
        transactions made on the connection are rolled back.</li>
      <li>Transaction isolation levels are now partially supported.&nbsp; Serializable
        is the default, which obtains read/write locks immediately -- this is compatible
        with previous releases of the provider.&nbsp; Unspecified will default to
        whatever the default isolation mode is set to, and ReadCommitted will cause a
        deferred lock to be obtained.&nbsp; No other values are legal.</li>
      <li>Revamped the test.exe program.&nbsp; It&#39;s now an interactive GUI application.&nbsp;
        Easier for me to add tests now.</li>
      <li>Tweaks to the VS designer package and installer.</li>
      <li>More adjustments to the internal SQLite3.Prepare() method to account for both
        kinds of lock errors when retrying.</li>
      <li>Stripped a lot of unnecessary interop() calls and replaced with base sqlite calls.&nbsp;
        Revamped most of UnsafeNativeMethods to make it easier to port the code.</li>
      <li>Rerigged internal callbacks for userdef functions and other native to managed
        callbacks.&nbsp; More portable this way.</li>
      <li>Source can now can be compiled with the SQLITE_STANDARD preprocessor symbol to
        force the wrapper to use the stock sqlite3 library.&nbsp; Some functionality is
        missing, but its minimal.&nbsp; None of the precompiled binaries are compiled
        using this setting, but its useful for testing portability.</li>
      <li>Added &quot;boolean&quot; and a couple other missing datatypes to the &quot;DataTypes&quot; schema
        xml file.&nbsp; Used by the VS designer when displaying tables and querying.</li>
      <li>Added a new connection string option &quot;Read Only&quot;.&nbsp; When set to True, the
        database will be opened in read-only mode.</li>
      <li>Added a new connection string option &quot;Max Pool Size&quot; to set the maximum size
        of the connection pool for a given db file connection.</li>
      <li>Added a new connection string option &quot;Default IsolationLevel&quot; to set the
        default isolation level of transactions.&nbsp; Possible values are Serializable and
        ReadCommitted.</li>
      <li>Added a new connection string option &quot;URI&quot; as an optional parameter for
        compatibility with other ports of the provider.</li>
    </ul>
    <p><b>1.0.54.0 - July 25, 2008</b></p>
    <ul>
      <li>Fixed the setup project, which somehow &quot;forgot&quot; to include all the binaries in
        the 53 release.</li>
      <li>Fixed a crash in the table designer when creating a new table and tabbing past
        the &quot;Allow Nulls&quot; cell in the grid while creating a new column.</li>
      <li>Fixed a mostly-benign bug in SQLiteDataReader&#39;s GetEnumerator, which failed to
        pass along a flag to the underyling DbEnumerator it creates.&nbsp; This one&#39;s
        been around since day 1 and nobody&#39;s noticed it in all these years.</li>
      <li>Added a new connection string parameter &quot;Journal Mode&quot; that allows you to set
        the SQLite journal mode to Delete, Persist or Off.</li>
    </ul>
    <p><b>1.0.53.0 - July 24, 2008</b></p>
    <ul>
      <li>Enabled sqlite_load_extension</li>
      <li>Added retry/timeout code to SQLite3.Prepare() when preparing statements for
        execution and a SQLITE_BUSY error occurs.</li>
      <li>Added a new schema to SQLiteConnection.GetSchema() called <i>Triggers</i>.&nbsp;
        Used to retrieve the trigger(s) associated with a database and/or table/view.</li>
      <li>Extensive updates to table/view editing capabilities inside Visual Studio&#39;s
        Server Explorer.&nbsp; The program now parses and lets you edit CHECK constraints and
        triggers on a table, as well as define triggers on views.&nbsp; Experimental
        still, so e-mail me if you have issues.</li>
      <li>Minor bugfix to the ViewColumns schema to return the proper base column name
        for a view that aliases a column.</li>
      <li>Fixed the insert/update/delete DML support in the Linq module.</li>
      <li>Changed the behavior of SQLiteCommand to allow a transaction to be set even if
        the command hasn&#39;t been associated with a connection yet.</li>
    </ul>
    <p><b>1.0.52.0 - July 16, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.6.0</li>
      <li>Added a lot of previously-missing exports to the DEF file for the
        native library.</li>
      <li>Fixed SQLiteDataReader to check for an invalid connection before operating on
        an open cursor.</li>
      <li>Implemented the Cancel() function of SQLiteCommand to cancel an active reader.</li>
      <li>Added beta table and view designers to the Visual Studio Server Explorer.&nbsp; You can now
        edit/create tables and views, manage indexes and foreign keys from Visual Studio.&nbsp;
        This feature is still undergoing testing so use at your own risk!</li>
      <li>Fixed the Server Explorer so VS2005 users can once again right-click tables
        and views and open the table data.</li>
      <li>Added some new interop code to assist in returning more metadata not normally
        available through the SQLite API.&nbsp; Specifically, index column sort modes
        and collating sequences.&nbsp; Also added code to detect (but not parse) CHECK
        constraints, so the table designer can pop up a warning when editing a table
        with these constraints.&nbsp; Since I can&#39;t currently parse them.</li>
      <li>Lots of LINQ SQL generation improvements and fixes.</li>
      <li>Made some progress cleaning up and fixing up the schema definitions and
        manifests for EdmGen.</li>
      <li>Added a built-in SQLiteFunction called last_rows_affected() which can be
        called from SQL to get the number of rows affected by the last update/insert
        operation on the connection.&nbsp; This is roughly equivalent to Sql Server&#39;s
        @@ROWCOUNT variable.</li>
    </ul>
    <p><b>1.0.51.0 - July 1, 2008</b></p>
    <ul>
      <li><b>VS2008 SP1 Beta1 LINQ Support</b></li>
      <li>Added experimental Entity Framework support in a new library,
        System.Data.SQLite.Linq.&nbsp; Some things work, some don&#39;t.&nbsp; I haven&#39;t
        finished rigging everything up yet.&nbsp; The core library remains stable.&nbsp;
        All LINQ-specific code is completely separate from the core.</li>
      <li>&nbsp;Added some columns to several existing schemas to support some of the
        EDM framework stuff.</li>
      <li>Minor tweaks to the factory to better support dynamic loading of the Linq
        extension library for SQLite.</li>
      <li>SQLite&#39;s busy handler was interfering with the provider&#39;s busy handling
        mechanism, so its been disabled.</li>
    </ul>
    <p><b>1.0.50.0 - June 27, 2008</b></p>
    <ul>
      <li>Fixed some lingering dispose issues and race conditions when some objects were finalized.</li>
      <li>Fixed the SQLiteConvert.Split() routine to be a little smarter when splitting
        strings, which solves the quoted data source filename problem.</li>
      <li>Enhanced the mergebin utility to work around the strong name validation bug on
        the Compact Framework.&nbsp; The old workaround kludged the DLL and caused WM6.1
        to fail to load it.&nbsp; This new solution is permanent and no longer kludges
        the DLL.</li>
    </ul>
    <p><b>1.0.49.0 - May 28, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.5.9</li>
      <li>Fixed schema problems when querying the TEMP catalog.</li>
      <li>Changed BLOB datatype schema to return IsLong = False instead of True.&nbsp; This
        was preventing DbCommandBuilder from using GUID's and BLOB's as primary keys.</li>
      <li>Fix rollover issue with SQLite3.Reset() using TickCount.</li>
      <li>Fixed SQLiteDataReader to dispose of its command (if called for) before
        closing the connection (when flagged to do so) instead of the other way around.</li>
      <li>Fixed a DbNull error when retrieving items not backed by a table schema.</li>
      <li>Fixed foreign key constraint parsing bug.</li>
      <li>Added FailIfMissing property to the SQLiteConnectionStringBuilder.</li>
      <li>Converted the source projects to Visual Studio 2008.</li>
    </ul>
    <p><b>1.0.48.0 - December 28, 2007</b></p>

    <ul>
    <li>Fixed a bug when using CommandBehavior.KeyInfo whereby integer primary key columns may be duplicated in the results. </li>
      <li>Enhanced the CommandBuilder so that update/delete statements are optimized when the affected table contains unique constraints and
      a primary key is present.</li>
      <li>Fixed a bug in the DataReader when used in conjunction with CommandBehavior.CloseConnection.</li></ul>
    <p><b>1.0.37.0 - November 19, 2006</b></p>
    <ul>
    <li>Added support for CommandBehavior.KeyInfo.&nbsp;
      When specified in a query, additional column(s) will be returned describing the
      key(s) defined for the table(s) selected in the query.&nbsp; This is optimized when
      INTEGER PRIMARY KEY is set for the given tables, but does additional work for other
      kinds of primary keys.</li>
      <li>Removed the default values from SQLiteDataReader.GetTableSchema(), to better follow

        implemented, but unfortunately inserting and updating data in a DataTable or
        DataSet is now much slower.&nbsp; This is the proper design however, so the
        changes are here to stay.

        Lots of schema changes to support Visual Studio's Data Designer architecture.<li>Added
          Designer support for the provider.&nbsp; It's not 100%, but you can design

          Modified SQLite3.Reset() and Step() functions to transparently handle timeouts

          <STRONG>For everything except the Compact Framework, System.Data.SQLite.DLL is

        assembly is now a multi-module assembly, containing both the native SQLite3
        codebase and the C# classes built on top of it.&nbsp; The Compact Framework
        version (when completed) will not be able to support this feature, so backwards
        compatibility with the Compact Framework has been preserved for the future.

          Fixed a bug in SQLiteCommand.ExecuteScalar() that caused it to stop executing
          commands once it obtained the first column of the first row-returning

        Fixed a bug in the SQLite3.cs Prepare() function that created a statement even
        when the SQLite engine returned a NULL pointer. Typically this occurs when
        multiple statements are processed and there are trailing comments at the end of
        the statement.
        <LI>
          Fixed a bug in SQLiteStatement.cs that retrieved parameter names for a
          parameterized query.&nbsp; SQLite's parameters are 1-based, and the function
          was starting at 0.&nbsp; This was fine when all parameters were unnamed, but
          for named parameters it caused the parameters to be out of whack.

        Speed-ups to SQLiteDataReader.&nbsp; It was interop'ing unnecessarily every

        Changed/Added some code to SQLiteConvert's internal DbType, Type and
        TypeAffinity functions.

        Fixed the SQLiteDataReader to obey the flags set in the optional
        CommandBehavior flag from SQLiteCommand.ExecuteReader().

        Changed the default page size to 1024 to reflect the defaults of SQLite.&nbsp;
        Ignores the "Page Size" connection string option for memory databases, as tests
        revealed that changing it resulted in memory corruption errors.
        <LI>
          Performance enhancements to the SQLiteCommand and SQLiteStatement classes which

        Fixed the SQLite3 C# class step/reset functions to accomodate schema changes
        that invalidate a prepared statement.&nbsp; Statements are recompiled
        transparently.
        <LI>
        Moved all native DLL declarations to an UnsafeNativeMethods class.
        <LI>
        Split several classes into their own modules for readability.
        <LI>
        Renamed many internal variables, reviewed access to variables marked as
        internal and altered their protection levels accordingly.
        <LI>
        Due to the presence of the altered sqlite3 codebase and so many added interop
        functions, I decided to rename the sqlite3 C project and the DLL to
        SQLite.Interop.DLL.&nbsp; This is the same core sqlite3 codebase but designed
        specifically for this ADO.NET provider.&nbsp; This eliminates any possibility
        of someone dropping another build of sqlite3.dll into the system and rendering
        the provider inoperable.&nbsp; In the future if the folks at sqlite.org finally
        introduce a method of retrieving column usage for an arbitrary prepared
        statement, I'll retool this library to be a lightweight function call wrapper
        around the core binary distribution.
        <LI>
        Added [SuppressUnmanagedCodeSecurity] attribute to the UnsafeNativeMethods
        class which brings VS2005 November CTP execution speeds inline with the
        December CTP.
        <LI>
          Added a <B>bin</B>
        directory to the project root where pre-compiled binaries can be found.
        <LI>
          Added a <B>doc</B>
        directory where preliminary documentation on the class library can be found.

        Removed the SQLiteContext class and revamped the way UserFunctions work to
        simplify the imlementation.
        <LI>
        Fixed a counting bug in the TestCases class, specifically in the function tests
        where I wasn't resetting the counter and it was consequently reporting
        intrinsic and raw select calls as being much much faster than they actually
        were.&nbsp; The numbers are now much closer to what I expected for performance,
        with .NET user-functions still being the slowest, but only by a small margin.
        <LI>
        Small performance tweaks to SQLiteDataReader.
        <LI>
        Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the
        SQLiteConnection
        <LI>
          Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after
          opening a connection.

        Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted
        in an enormous performance boost in the InsertMany test.&nbsp;&nbsp; 10,000 row
        insert that executed in 1500ms now executes in 500ms.
        <LI>
        Fixed several errors in the SQLite3_UTF16 class.&nbsp; ToString() was working
        incorrectly and the Open() method failed to register user defined functions and
        collations.
        <LI>
        Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement
        was being properly cleaned up.
        <LI>
        Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly
        reset the previously-executed command in the sequence.
        <LI>
          Added an InsertManyWithIdentityFetch test, which appends a select clause to
          populate the ID of the last inserted row into the InsertCommand, demonstrating
          ADO.NET's ability to auto-fetch identity columns on insert.

      <UL>
        <LI>
        Tweaks to the xxx_interop functions that return char *'s, so they also return
        the length.&nbsp; Saves an interop call to get the UTF-8 string length during
        conversion to a .NET string.
        <LI>
        Reworked the whole interop.c thing into interop.h and reduced the code required
        to merge the main sqlite3 codebase.
        <LI>
          Added support for user-defined collations.
