+2015-09-30 1.3 release
+
+           o add new option, "log4jdbc.trim.sql.lines" which when set,
+             will trim SQL line by line (for beginning of line, only trimming
+             consistent white space) If this option is selected, the TrimSql
+             option will be ignored.
+
+           o remove JDBC 3 version (not all scripts updated yet.)
+
+           o getArray method improperly labeled as getURL (Issue 61.)
+
+           o bug fix ResultSetSpy.getStatement should return wrapped Statement,
+             not real Statement (Issue 55.)
+
+           o move to GitHub (Google Code shutting down.)
+
+2012-02-17 1.2 Release
+
+           o escape single quotes in PreparedStatement/CallableStatement bind variables (Issue 36.)
+
+           o process SQL consistently when the sql is dumped because an exception occurred.
+
+           o new SQL formatter to more reliably dump sql that can be run for MySql (Issue 34.)
+
+           o don't show debug info in sql timing dump unless debug is enabled on the logger
+             (to make the sql timing dump consistent with the way other the loggers work)
+
+           o add new option, log4jdbc.trim.sql.extrablanklines for removing
+             extra blank lines from sql output.
+
+           o fix issue where extra connection was being created when
+             ResultSet.getStatement was being called (Issue 33.)
+
+           o performance enhancement when logging not enabled (Issue 29.)
+
+2010-06-09 1.2 beta 2 Release
+
+           o add new option, log4jdbc.auto.load.popular.drivers for
+             disabling auto-loading of drivers
+
+           o look first for log4jdbc property settings in optional
+             log4jdbc.properties file in the classpath.
+
+           o Fix non-threadsafe usage of SimpleDateFormat (Issue 18)
+
+           o add new option, log4jdbc.trim.sql to trim the SQL before logging
+             it.
+
+           o add new option, log4jdbc.suppress.generated.keys.exception that
+             will ignore any exception produced by the method,
+             Statement.getGeneratedKeys().  This flag is useful in Coldfusion
+             environments which typically call this method after every update,
+             even if unwarranted, and ignoring the exception, thus clogging up
+             the logs with these exception reports.
+
+           o add support for the newer oracle.jdbc.OracleDriver driver (the
+             older oracle.jdbc.driver.OracleDriver driver is still supported
+             as well) and add corrected date formatting for Oracle.
+
+           o fix possible null pointer issue with setBlob and setClob (Issue 21)
+
+2010-03-20 1.2 beta 1 Release
+
+           o Check for exception that should not, but in some cases could
+             occur when trying to format parameter arguments.
+
+           o Use only one type of date format so that time portion of Date
+             types is not dropped!
+
+           o use to_date function for Oracle (Issue 14)
+
+           o performance improvements
+
+           o fix: respect DumpSqlMaxLineLength option.
+
+           o various other fixes (including Issues 8 and 9)
+
+2009-02-26 1.2 alpha 2 Release
+
+           o (Issue 1) fix bug where batch of logged SQL wasn't cleared
+             properly when using batched SQL.
+
+           o Added log4jdbc.statement.warn system property; defaults to false.
+
+             This is a new option to control the SQL Statement warnings in the
+             log.  When Statement objects are used by the application, the SQL
+             in the log is preceded by "{WARNING: Statement used to run SQL}"
+             This was always on in previous releases.  Now it
+             is off by default, and can be turned on by setting this property.
+
+           o (Issue 2) add getter methods across the board for the real
+             wrapped object.
+
+2008-11-08 1.2 alpha 1 Release
+
+           o added a new logger "jdbc.connection" to dump connection open and
+             close events as well as dumping all open connection numbers.  This
+             is very useful for hunting down connection leak problems.
+
+           o several new options to produce better SQL output:
+
+             log4jdbc.dump.booleanastruefalse - many RDBMS's don't have a
+             native boolean type and store booleans as a 1 or 0.  Setting this
+             option to false will show boolean bind variables as 1 or 0.
+             Setting this to true will show the boolean as true or false.
+             (Note that the default for this setting is false, contrary to the
+             previous way log4jdbc worked.)
+
+             log4jdbc.dump.sql.maxlinelength - can be used to insert line
+             breaks into long running SQL (at white space positions.)
+             previous versions of log4jdbc did this automatically with a value
+             of 90 (the default value is 90.)  This line breaking can be turned
+             off completely by setting this to 0.
+
+             log4jdbc.dump.fulldebugstacktrace - can be used in extreme
+             debugging circumstances when you want to be able to see the full
+             stack trace in the debug output.  Be extra careful when using
+             this as it will obviously produce much much more logging output.
+
+           o dump a null bind variable as NULL instead of <null> for more
+             accurate and reuseable SQL output.
+
+           o several new options for controlling what types of SQL statements
+             are logged:
+
+             log4jdbc.dump.sql.select   default value is true
+             log4jdbc.dump.sql.insert   default value is true
+             log4jdbc.dump.sql.update   default value is true
+             log4jdbc.dump.sql.delete   default value is true
+             log4jdbc.dump.sql.create   default value is true
+
+             The default values for all of these are true, but they can be
+             selectively turned on and off to filter out unwanted types of sql
+             statements.  For example, setting log4jdbc.dump.sql.delete will
+             cause all DELETE sql commands to not be logged.
+
+           o A new option to add a semi colon to the end of the dumped sql:
+
+             log4jdbc.dump.sql.addsemicolon   default value is false
+
+             Sometimes it's useful to use log4jdbc to produce sql scripts that
+             can later be fed back into a SQL tool to execute against a
+             database and this option can help to produce more re-useable sql
+             output script data from a log file.
+
+           o added Microsoft SQL Server 2005 Driver
+             (com.microsoft.sqlserver.jdbc.SQLServerDriver) to
+             list of "well known" drivers that log4jdbc looks for at startup.
+             (thanks to Rob Richards for pointing this out)
+
+             Note that the SQL Server 2000 Driver with the confusing name
+             of (com.microsoft.jdbc.sqlserver.SQLServerDriver) is also still
+             supported.
+
+           o other miscellaneous improvements.
+
+2008-04-11 1.1 Release
+
+           o upgrade to SLF4J 1.5.  Note that log4jdbc should still work with
+             any older (or newer) version of SLF4J too.
+
+           o slightly better fault tolerance for when loading/probing of
+             popular JDBC drivers fails for any reason.
+
 2007-11-10 1.1 beta 1 Release
 
-           o added HSQLDB (org.hsqldb.jdbcDriver) and H2 (org.h2.Driver)
-             to list of "well known" drivers that log4jdbc looks for at startup.
-             
-           o added log4jdbc.sqltiming.warn.threshold and log4jdbc.sqltiming.error.threshold system property
-             settings to greatly aid in finding slow running sql.  Special thanks to Lilianne E. Blaze for the idea
-             and initial implementation.
+           o added HSQLDB (org.hsqldb.jdbcDriver) and H2 (org.h2.Driver) to

-  Full support for JDBC 3 and JDBC 4!
-</li>
-
-<li>
-  Easy to configure, in most cases all you need to do is change the driver class name
-  and prepend <b>"jdbc:log4"</b> to your existing jdbc url, set up your logging categories and
-  you're ready to go!
-</li>
-
-<li>
-  In the logged output, for prepared statements, the bind arguments are automatically
-  inserted into the SQL output.  This greatly Improves readability and debugging for
-  many cases.
-</li>
-
-<li>
-  SQL timing information can be generated to help identify how long SQL statements take
-  to run, helping to identify statements that are running too slowly and this data can
-  be post processed with an included tool to produce profiling report data for quickly
-  identifying slow SQL in your application..
-</li>
-
-<li>
-  SQL connection number information is generated to help identify connection pooling or

-<li><p> Decide if you need JDBC 3 or JDBC 4 support.  The most straightforward way to decide this is:</p>
-    <ul>
-      <li>If you are using JDK 1.4 or 1.5, you should use the JDBC 3 version of log4jdbc.</li>
-      <li>If you are using JDK 1.6 or 1.7, you should use the JDBC 4 version of log4jdbc (even if the actual underlying JDBC driver you are using is a JDBC 3 or older driver).</li>
-    </ul>
-    <p>
-    Currently there are very few actual JDBC 4 drivers on the market.  (The only major one that I really know about is Apache Derby aka The Java DB distributed with JDK 1.6.)
-    JDBC 4 support was added with the JDK 1.6 release and adds many additional features over and above JDBC 3.
-    However, the log4jdbc JDBC 4 driver can wrap a JDBC 3 or older driver and
-    it's recommended that if you use JDK 1.6 or above, that you use the log4jdbc JDBC 4 driver that is compiled with JDK 1.6.
-    </p>
-    <p>
-    Note that JDBC 2 is not currently supported by log4jdbc (there is an older unreleased version of log4jdbc with JDBC 2 support,
-    but I decided not to release it because JDBC 3 has been out for so long, I don't anticipate much demand for a JDBC 2 version of
-    log4jdbc at this point), although if you are using JDK 1.4 and above, the log4jdbc 3.0 or 4.0 driver
-    should be able to wrap an older JDBC 2 driver as well-- log4jdbc just won't work with Java 1.3 and earlier.
-    Please <a href="#feedback">email me</a> if you really really want a JDBC 2 version of log4jdbc.  If there is enough demand, I may resurrect it.
-    </p>
-    </p>
-    <pre>
-
-    Choose and <a href="http://sourceforge.net/project/showfiles.php?group_id=194500&package_id=229335&release_id=527690">download</a> one of the driver .jar files:
-
-        log4jdbc3-1.1beta1.jar      JDBC 3 support for JDK 1.4 , JDK 1.5
-        log4jdbc4-1.1beta1.jar      JDBC 4 support for JDK 1.6 , JDK 1.7
-
-    Place the log4jdbc jar that you choose into your application's classpath.
-    </pre>
-
-<li><p>Choose which java logging system you will use. </p>
-     In many cases, you already know this, because it is dictated by your existing application.
-     log4jdbc uses the Simple Logging Facade for Java (SLF4J) which is a very simple and very flexible little library that lets you pick among many common java logging systems:</p>
-     <ul>
-     <li>Log4j</li>
-     <li>java.util logging in JDK 1.4</li>
-     <li>logback</li>
-     <li>Jakarta Commons Logging</li>
-     </ul>
-
-     <p> SLF4J is designed to de-couple your application from the java logging system so you can choose any one you want.  This is the same goal of Jakarta Commons Logging.  However many people have
-        had headaches and issues with classloading problems in complex environments using Jakarta Commons Logging.  SLF4J solves these problems with it's much simpler design, and you can even integrate
-        SLF4J to use Jakarta Commons Logging, if you really want to (or are required to) use it.</p>
-     <pre>
-
-     <a href="http://www.slf4j.org/download.html">Download</a> the latest official SLF4J release.
-
-     You will need two jars:
-
-        slf4j-api-1.4.3.jar (or the latest available version) and
-        whichever jar you pick depending on the java logging system you choose
-
-    Place these two .jar files into your application's classpath.
-    </pre>
-
-    Please read the documentation at the <a target="slf4j" href="http://slf4j.org">SLF4J website</a>.  It's really easy to set up!
-
-     </a>
-<li><p>Set your jdbc driver class to <code>net.sf.log4jdbc.DriverSpy</code> in your application's configuration.</p>
-    <p>
-    The underlying driver that is being spied on in many cases will be loaded automatically
-    without any additional configuration.
-    </p>
-  <p>
-    The log4jdbc "spy" driver will try and load the following popular jdbc drivers:

-    If you want to use a different underlying jdbc driver that is not already in the above supported list,

-    can also be a comma separated list of driver class names if you need more than one.
-  </p>
-  <p>
-    (optional) <code>-Dlog4jdbc.drivers=&lt;driver&gt;[,&lt;driver&gt;...]</code>  If your driver is not one of the common preloaded drivers.
-  </p>
-</li>
-<li><p> Prepend <code>jdbc:log4</code> to the normal jdbc url that you are using.</p>
-
-    <p>For example, if your normal jdbc url is</p>
-
-    <p><code>jdbc:derby://localhost:1527//db-derby-10.2.2.0-bin/databases/MyDatabase</code></p>
-    <p>then You would change it to: </p>
-    <p><code><b>jdbc:log4</b>jdbc:derby://localhost:1527//db-derby-10.2.2.0-bin/databases/MyDatabase</code></p>
-    <p>to use <b>log4jdbc.</b></p>
-</li>
-<li> <p> Set up your logging categories.  There are 4 categories that are used by log4jdbc,
-    If all 4 loggers are set to a level less than error (such as the FATAL level), then log4jdbc will not log
-    anything, and in fact the actual (real) connection to the underlying database will be returned by the log4jdbc
-    driver (thus allowing log4jdbc to be installed and available to turn on at runtime at a moment's notice,
-    without imposing any actual performance loss when not being used).  If any of the 4 logs are set to ERROR,INFO or
-    DEBUG, then log4jdbc will be activated, wrapping and logging all activity in the jdbc connections returned by the
-    underlying driver.</p>
-    <pre>
-
-    Each of these logs can be set at either DEBUG, INFO or ERROR
-    DEBUG includes the class name and line number (if available) at which the sql was executed.
-    INFO  includes the sql (or other information as applicable)
-    ERROR will show the stack traces in the log output when sql exceptions occur.
-
-    jdbc.sqlonly   shows only SQL in the log.  SQL executed within a prepared statement is automatically shown with
-                   it's bind arguments replaced with the data bound at that position, for greatly increased readability.
-
-    jdbc.sqltiming shows the SQL, post-execution, including timing statistics on how long the sql took to execute.
-
-    jdbc.audit     Logs ALL jdbc calls except for ResultSets.  This is a very voluminous output, and is not normally
-                   needed unless tracking down a specific jdbc problem.
-
-    jdbc.resultset Even more voluminous, because all calls to ResultSet objects are logged.
-    </pre>
-
-    <p>Additionally, there is one logger named <b>log4jdbc.debug</b> which is for use with internal debugging of log4jdbc.
-    At this time it just prints out information on which underlying drivers were found and not found when the
-    log4jdbc spy driver loads.</p>
-
-    <p>In a typical usage scenario, you might turn on only the jdbc.sqlonly logging at INFO level,
-    just to view the sql coming out of your program.</p>
-
-    <p>Then if you wanted to view how long each sql statement is taking to execute, you might use jdbc.sqltiming.</p>
-
-    <p>jdbc.audit and jdbc.resultset are used for more in depth diagnosis of what is going on under the hood with jdbc
-    as potentially almost every single call to jdbc could be logged (logs can grow very large, very quickly with this!)</p>
-
-    <p>SLF4J is a logging facade that can be used with many popular java logging systems.  The setup for the logging
-      categories will vary depending on which underlying logger you use.  Sample configuration files for log4j are
-      provided here:  <a href="log4j.xml">log4j.xml</a> and <a href="log4j.properties">log4j.properties</a>.</p>
-</li>
-<li><p>Adjust debugging options.  When logging at the DEBUG level, the class file and line number (if available) for the
-    class that invoked jdbc is logged after each log statement.  This is enormously useful for finding where in the
-    code the SQL is generated.  Be careful when using this on a production system because there is a small, but
-    potentially significant penalty performance for generating this data on each logging statement.</p>
-
-    <p>In many cases, this call stack data is not very useful because the calling class into log4jdbc is a connection pool,
-    object-persistance layer or other layer between log4jdbc and your application code-- but the class file and
-    line number information you really are interested in seeing is where in your application the SQL was generated from.</p>
-
-    <p>Set the <code>log4jdbc.debug.stack.prefix</code> System property for log4jdc to help get around this problem:</p>
-
-    <p>
-    (optional) <code>-Dlog4jdbc.debug.stack.prefix=&lt;package.prefix&gt;</code>  a String that is the partial (or full) package
-       prefix for the package name of your application.  The call stack will be searched down to the first occurence
-       of a class that has the matching prefix.  If this is not set, the actual class that called into log4jdbc is used
-       in the debug output (in many cases this will be a connection pool class)</p>
-     <p>
-     For example, setting a system property such as this:  <code>-Dlog4jdbc.debug.stack.prefix=com.mycompany.myapp</code>
-     Would cause the call stack to be searched for the first call that came from code in the com.mycompany.myapp package or below,
-     thus if all of your sql generating code was in code located in the com.mycompany.myapp package or any subpackages,
-     this would be printed in the debug information, rather than the package name for a connection pool, object relational system, etc.

-<ul class="left">
-<li>A simple tool is included which you can use to post-process sql timing logs produced by log4jdbc.
-  It produces produce simple profiling reports with statistics and a dump of the sql statements that ran the slowest within the log.
-  To invoke the tool, use the profsql.sh (for unix/linux) and profsql.cmd (for windows) scripts located in the scripts
-  folder.  These scripts take as one argument, the filename of a sql timing log (generated from the
-  <code>jdbc.sqltiming</code> log category.  They produce a profiling report to stdout.
-  The tool is currently experimental and I expect it to evolve quite a bit over the next few releases.
-  Nevertheless, it has already been very useful to me for tracking down SQL performance problems.
-</li>
-<li>
-  Starting with the 1.1 beta 1 release, you can set timing thresholds to more easily find slow running SQL.  These are set via system properties:
-  <p>
-    <code>-Dlog4jdbc.sqltiming.warn.threshold=&lt;number of milliseconds&gt;</code> causes SQL that takes &lt;number of milliseconds&gt; or more time to execute to be logged at the <b>warning</b> level in the sqltiming log.
-  </p>
-  <p>
-    <code>-Dlog4jdbc.sqltiming.error.threshold=&lt;number of milliseconds&gt;</code> causes SQL that takes &lt;number of milliseconds&gt; or more time to execute to be logged at the <b>error</b> level in the sqltiming log.
-  </p>
-  <p>
-    Note that the sqltiming log must be enabled at the warn or error log levels for these features to work.  Also the logged output for both of these settings will log with debug information that is normally only shown
-    when the sqltiming log is enabled at the debug level.  This can help you to more quickly find slower running SQL without adding overhead or logging for normal running
-    SQL that executes below the threshold level (if the logging level is set appropriately.)
