<p><b>1.0.36.1 - October 25, 2006</b></p>
<ul>
<li>Added support for LONGVARCHAR, SMALLDATE and SMALLDATETIME. These were actually added in 1.0.36.0 but were undocumented.</li>
<li>Fixed the embedded helpfile which was accidentally built from old sources. </li>
<li>Fixed an unfortunate re-entry of a bug in the .36 codebase that caused the provider to "forget" about commands on a connection under certain circumstances.</li>
</ul>
<p><b>1.0.36.0 - October 23, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.8, including support for full-text search via the FTS1
extension. </li><li>Fixed a bug retrieving data types when UseUtf16Encoding is true. Side-effect of further merging the common code between the two base classes.</li>
<li>Fixed a bug with System.Transactions whereby a connection closed/disposed within
a transaction scope is rolled back and cannot be committed.</li>
<li>Added more error checking and reporting to transactions to help user's isolate
the source of transaction failures.</li>
<li>Implemented a workaround for a Compact Framework issue regarding strong-named
assemblies containing a PE section with a raw size less than the virtual size. </li>
</ul>
<p><b>1.0.35.1 - September 12, 2006</b></p>
<ul>
<li>Fixed the TYPES keyword to work when UseUTF16Encoding is true.</li>
<li>Fix another bug revealed in 1.0.35.0 regarding infinite loops when the 2nd or subsequent statements of a semi-colon separated command cannot be parsed.</li>
<li>Updated the help documentation. </li>
</ul>
<p><b>1.0.35.0 - September 10, 2006</b></p>
<ul>
<li>Fixed an infinite loop bug in SQLiteCommand caused when multiple semi-colon separated
statements in a single command are executed via datareader and one of the statements
contains a syntax error preventing it from being prepared. </li><li>Added the TYPES preparser keyword to be placed before a SELECT statement to
aid the wrapper in converting expressions in a subsequent select clause into more
robust types. Documentation yet to be integrated, but available on the forums.</li>
<li>Added a new connectionstring parameter "BinaryGUID=true/false" (default is "true").
When true, guid types are stored in the database as binary blobs to save space.
Binary has been the default format since 1.0.32.0 but this parameter eases backward
compatibility.</li>
</ul>
<p><b>1.0.34.0 - September 4, 2006</b></p>
<ul>
<li>Fixed a bug in SQLiteParameterCollection.RemoveAt(namedparam)</li>
<li>Fixed a bug in SQLiteDataReader introduced in 1.0.30 that broke DateTimes using the Ticks option in the connection string.</li>
<li>Fixed a bug in the recent changes to guid behavior wherein using a datareader's
indexer to fetch a guid from a column containing both binary and text guids would
sometimes return a byte array instead of a guid.</li>
<li>Enacted a workaround involving typed datasets in Compact Framework projects in
which it took an excessive amount of time to open a form and generated a lot of
temporary files in the user's Local Settings\Application Data\Microsoft\VisualStudio\8.0\Assembly
References folder.</li>
</ul>
<p><b>1.0.33.0 - August 21, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.7</li>
<li>Fixed a bug in SQLiteConnection that caused it to "forget" about commands bound
to it and occasionally throw an error when a database is closed and opened repeatedly.
</li>
</ul>
<p><b>1.0.32.0 - August 6, 2006</b></p>
<ul>
<li>Added AllowPartiallyTrustedCallers attribute to the assembly</li><li>Added the missing "nchar" type</li>
<li>Added support for binary Guid's. Guids are now stored as binary by default
when using parameterized queries. Text guids are still fully supported.</li>
<li>Fixed a TransactionScope() error that caused the transaction not to be completed.</li>
<li>Enhanced parameter names so that if they are added to the Parameters collection
without their prefix character (@ : or $) they are still properly mapped. </li>
</ul>
<p><b>1.0.31.0 - July 16, 2006</b></p>
<ul>
<li>Re-applied the view parsing bugfix in 1.0.29.0 that was accidentally reverted
out of the 30 build.</li><li>Fixed SQLiteCommand.ExecuteScalar() to return null instead of DbNull.Value
when no rows were returned.</li>
<li>Design-time installer now installs the package-based designer on full Visual Studio
versions. Express editions continue to use the packageless designer.</li>
<li>In Visual Studio (not Express), you can now right-click a SQLite connection in
the Server Explorer and vacuum the database and change the encryption password.</li>
</ul>
<p><b>1.0.30.1 - July 2, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.6</li>
<li>Added support for the |DataDirectory| keyword in the Data Source filename string.
</li>
<li>Added hook notification support to SQLiteConnection. Specifically, there
are three new events on the SQLiteConnection object which are raised when an update/insert/delete
occurs and when transactions are committed and rolled back.</li><li>Changed SQLiteTransaction to default to BEGIN IMMEDIATE instead of just BEGIN,
which solves a multithreaded race condition. </li>
<li>Changed SQLiteDataReader to better support SQLite's typelessness. The data
reader no longer caches column affinity, but re-evaluates it for each column/row.</li>
<li>Fixed a bug in Prepare() which caused an intermittant fault due to the code accessing
the memory of an unpinned variable. </li>
<li>Fixed a multithreaded lock-retry bug in in SQLiteConnection.Open() and in
SQLiteTransaction, which failed to use a command timeout before giving up.</li>
</ul>
<p><b>1.0.29.0 - May 16, 2006</b></p>
<ul>
<li>Fixed a bug in the Views schema information which caused multi-line view definition statements not to be parsed</li>
<li>Fixed a parsing bug in SQLiteDataReader.GetSchemaTable() to account for numeric(x,y) datatypes with specified precision and scale</li>
<li>Fixed a bug in SQLiteConnection.Open() which tried to automatically enlist in an ambient transaction but had not yet set the state of the database to Opened, thereby causing a transaction fault</li>
<li>Changed SQLiteException to inherit from DbException on the full framework</li>
</ul>
<p><b>1.0.28.0 - April 14, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.5</li>
<li>You can now specify a relative path in the Compact Framework's "Data Source" by
prefixing the file with ".\". i.e. "Data Source=.\\mydb.db3"</li>
<li>Several more changes and enhancements to schemas for better compatibility.</li>
<li>Fixed several bugs with the 64-bit builds of the provider. The x64 binary
is now optimized.</li>
<li>Design-time installer now tries to install the 64-bit builds into the GAC along
with the 32-bit build.</li>
<li>Fixed a bug in the SQLiteDataReader.GetSchemaTable() function when used with tables
containing apostrophes.</li>
<li>Fixed an XSD-related bug whereby the XSD utility was unable to locate the provider
and could not generate typed datasets.</li>
<li>Added NTEXT and STRING datatypes to the list of recognized keywords (used for
schema retrieval).</li>
<li>Due to the XSD bug and other potential problems related to external build utilities,
changes to the installation of the designer have had to be made. The installer
used to write the DbProviderFactories XML into the devenv.exe.config file and its
express cousins, but now has to write instead to the machine.config.</li>
<li>Installer writes to both the 32-bit machine.config and the 64-bit machine.config
if it exists. </li>
</ul>
<p><b>1.0.27.1 - February 28, 2006</b></p>
<ul>
<li>Fixed a bug when doing data binding in Compact Framework projects that prevented
you from assigning a typed dataset to a bindingsource. It turns out, the CF
version of the SQLite provider needs to be flagged as retargetable so it'll work
in the design-time desktop environment. No changes were made to the desktop
build, but the revision was bumped on all libraries anyway in order to keep them
sync'd. </li></ul>
<p><b>1.0.27.0 - February 27, 2006</b></p>
<ul>
<li>Many optimizations and a few more minor adjustments to schemas and schema retrieval
performance.</li>
<li>Lots of design-time attributes added to the code. The DbDataAdapter, DbCommand,
and DbConnection objects now have greatly enhanced design-time capabilities when
added to the toolbox and dropped on a form.</li>
<li>Lots of Server Explorer enhancements.</li>
<li>Binaries are now distributed in a setup program for easier administration and
configuration of the provider.</li>
</ul>
<p><b>1.0.26.2 - February 15, 2006</b></p>
<ul>
<li>Yet another bugfix to index schemas, which was incorrectly marking most indexes
as primary key indexes.</li><li>Fixed GetSchema() to accept a null string array.</li><li>Fixed a misspelled export in the core C library that prevented databases opened
with UTF16Encoding from getting schema information and would likely cause an error
if attempted.</li></ul>
<p><b>1.0.26.1 - February 14, 2006</b></p>
<ul>
<li>Fixed even more minor schema bugs having to do with indexes.</li><li>Added two missing pieces in the SQLite designer which were preventing it from
being used from within VS Express editions. </li><li>Several bugfixes to the design-time installer program, including supporting
64-bit environments.</li></ul>
<p><b>1.0.26.0 - February 11, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.4</li><li>Fixed an encryption bug when changing the password of databases over 1gb in
size. </li><li>Fixed various designer issues related to construction of named parameters. </li><li>Retooled the GetSchema() method of SQLiteDataReader to use the new 3.3.4 API functions,
and made several enhancements and fixes to schemas. </li>
<li>Implemented the SourceColumnNullMapping property of SQLiteParameter to fix
a DbCommandBuilder code generation bug. </li>
<li>Removed the runtime dependency on MSVCR80.DLL. File size is somewhat
larger for the varying desktop versions, but the Compact Framework version remains
the same.</li><li>Created an install program to manage installation and uninstallation of the
SQLite design-time support.</li>
<li>Designer support now works for all Visual Studio editions, including all Express
Editions.</li>
<li>Design-time installer will now remove (if present) the machine.config SQLite entries
in favor of installing the xml code into the devenv.exe.config file (or any of the
variations for express editions). The officially-accepted behavior of using
DbProviderFactories is to add the code to your app.config file, and the machine.config
