+<div>
+<p>These notes describe the difference between Apache Derby release 10.8.1.2 and the preceding release 10.7.1.1.</p>

+<h3 class="boxed">Overview</h3>
+<div>
+<p>The most up to date information about Derby releases can be found on the <a href="http://db.apache.org/derby/derby_downloads.html">Derby download page</a>.</p>
+<p>Apache Derby is a pure Java relational database engine using standard SQL and JDBC as its APIs. More information about Derby can be found on the <a href="http://db.apache.org/derby/">Apache web site</a>. Derby functionality includes:</p>
+<ul>
+<li>Embedded engine with JDBC drivers</li>
+<li>Network Server</li>
+<li>Network client JDBC drivers</li>
+<li>Command line tools: ij (SQL scripting), dblook (schema dump) and sysinfo (system info)</li>
+</ul>
+<p>Java and JDBC versions supported:</p>
+<ul>
+<li>Java SE 1.4 and higher with JDBC 2.1, 3.0, 4.0 and 4.1</li>
+<li>Java ME CDC/Foundation Profile 1.1 with JSR-169 JDBC Optional Package for CDC/Foundation Profile.</li>
+</ul>
+<br>
+<br>
+</div>
+<a name="N100EA"></a><a name="New+Features"></a>
+<h3 class="boxed">New Features</h3>
+<div>
+<p>This is a feature release. The following new features were added:</p>
+<ul>
+<li>
+<strong>JDBC 4.1</strong> - Derby's JDBC drivers support the new Java 7 methods on the <em>java.sql</em> and <em>javax.sql</em> interfaces. This support works with the pre-GA OpenJDK 7 build 131 available at http://download.java.net/jdk7/ on March 3, 2011. Derby's implementation of these interfaces may change in a future release in the highly unlikely event that the actual GA version of these interfaces changes.</li>
+<li>
+<strong>Automatic calculation of index statistics</strong> - Derby automatically refreshes statistics to help it pick better query plans.</li>
+<li>
+<strong>Improved interrupt handling</strong> - Interrupting connection threads no longer crashes the Derby engine.</li>
+<li>
+<strong>MAX optimization</strong> - On indexed tables, MAX queries run faster in more cases.</li>
+<li>
+<strong>XML operator portability</strong> - The xmlparse and xmlserialize operators work out-of-the-box on more platforms.</li>
+</ul>
+</div>

+<h4>Summary of Change</h4>

+-->
+<h4>Symptoms Seen by Applications Affected by Change</h4>
+<p>In Derby 10.7.1.1, UPDATE triggers which use the REFERENCING clause can be confused about which columns to pass to their triggered actions. This can silently corrupt data manipulated by the triggered actions.</p>

+<h4>Incompatibilities with Previous Release</h4>
+<p>Derby 10.7.1.1 is the only release whose triggers corrupt data this way. Upgrading to a later 10.7 release or to 10.8 will recompile these triggers correctly. Applications should check for data corruption if they used 10.7.1.1 to create UPDATE triggers with the REFERENCING clause.</p>

+<h4>Application Changes Required</h4>
+<p>If the application expects the parameter to be set to "1" or "0" instead of "true" or "false", it must be recoded to explicitly set the parameter to an integer value.</p>
+<p>For example, if an application uses setBoolean() to set a character type parameter, it could be changed from</p>

+<p>After a severe error (system crash or session error), the Derby error log will snapshot stack traces for all threads. On IBM JVMs these errors will produce a javacore file too.</p>
+<p>To obtain thread dumps and diagnostics for less severe errors, adjust the <em>derby.stream.error.extendedDiagSeverityLevel</em> property as described in the <a href="http://db.apache.org/derby/docs/10.7/devguide/cdevsetprop16827.html">Setting system-wide properties</a> section of the Derby Developer's Guide. Please consult the Derby documentation for explanations of error severities and the other possible settings of <em>extendedDiagSeverityLevel</em>.</p>
+<p>For example, to obtain this extra information while diagnosing deadlocks, set <tt>derby.stream.error.extendedDiagSeverityLevel=30000</tt>. Then deadlocks will dump thread stacks into the Derby error log.</p>

+<h4>Symptoms Seen by Applications Affected by Change</h4>
+<p>In release 10.1, orderly engine shutdown unregistered the embedded JDBC driver, allowing the JVM to garbage-collect the Derby classes. Later releases (10.2 through 10.7) did not unregister the driver. 10.8 revives the 10.1 behavior. In 10.8, orderly engine shutdown unregisters the embedded JDBC driver.</p>
+<p>After the embedded driver has been unregistered, it must be re-registered in order to obtain a new Connection to Derby. Re-registration occurs when the application invokes the following statement:</p>
+<tt>Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();</tt> 
+<p>It is also possible for an application to request orderly shutdown without unregistering the embedded driver. After such a shutdown it is not necessary to re-register the embedded driver. To request this kind of shutdown, the application needs to add <tt>deregister=false</tt> to the end of the shutdown URL. For more information on this feature, please see the section on the <em>deregister</em> attribute in the Derby Reference Manual.</p>

+-->
+<h4>Symptoms Seen by Applications Affected by Change</h4>
+<p>After upgrading to Derby 10.8, applications may fail if they use the XMLPARSE, XMLSERIALIZE, XMLQUERY, and XMLEXISTS operators. Using those operators may raise the following error message:</p>
+<pre>ERROR XML00: Failed to locate 'XPath 3.0' API or implementation classes.  XML operations are not permitted unless these classes are in your classpath.
+</pre>
+<p>This happens if the classpath doesn't include the <a class="external" href="http://www.w3.org/TR/DOM-Level-3-XPath/">DOM Level 3 XPath</a> interfaces or an implementation of those interfaces.</p>
+<h4>Incompatibilities with Previous Release</h4>
+<p>On Java 5 and earlier JVMs, the XMLPARSE, XMLSERIALIZE, XMLQUERY, and XMLEXISTS operators may fail as described above.</p>
+<!-- 
+  DESCRIBE WHY THE CHANGE WAS MADE.
+
+  For instance:
+
+  The previous behavior violated the JDBC standard. The new behavior
+  is correct.
+-->
+<h4>Rationale for Change</h4>
+<p>Previous releases of Derby required a recent version of Apache Xalan-Java in order to support the XML operators. Since not all platforms include Apache Xalan-Java, and some platforms contain a modified version with a different interface, these operators didn't work out of the box on many platforms.</p>
+<p>In this release, the XML operators access the platform's XML libraries via the <em>javax.xml</em> and <em>org.w3c.dom</em> interfaces instead of accessing the Xalan implementation classes directly. This change makes the XML operators work out of the box on most Java SE 6 or later platforms, but may break the functionality on older platforms that don't contain all the required interfaces.</p>

+  For instance:

+-->
+<h4>Application Changes Required</h4>
+<p>In environments affected by this change, the XML operators can be fixed by upgrading the JVM (IBM's versions 1.5.0 and 1.6.0 and Oracle's version 1.6.0 are known to work) or by installing a recent version of Apache Xalan-Java.</p>
+<p>Installation of Xalan-Java may require the Endorsed Standards Override Mechanism. This is described in the "XML data types and operators" section of the Derby Developer's Guide.</p>

+<p>It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.</p>
+<p>The PGP signatures can be verified using <a class="external" href="http://www.pgpi.org/">PGP</a> or <a class="external" href="http://www.gnupg.org/">GPG</a>. First download the Apache Derby <a class="external" href="http://www.apache.org/dist/db/derby/KEYS">KEYS</a> as well as the <span class="codefrag">asc</span> signature file for the particular distribution. It is important that you get these files from the ultimate trusted source - the main ASF distribution site, rather than from a mirror. Then verify the signatures using ...</p>
+<pre>% pgpk -a KEYS
+% pgpv db-derby-X.Y.tar.gz.asc
+
+<em>or</em>
+
+% pgp -ka KEYS
+% pgp db-derby-X.Y.tar.gz.asc
+
+<em>or</em>
+
+% gpg --import KEYS
+% gpg --verify db-derby-X.Y.tar.gz.asc
+
+</pre>
+<p>To verify the MD5 signature on the files, you need to use a program called <span class="codefrag">md5</span> or <span class="codefrag">md5sum</span>, which is included in many unix distributions. It is also available as part of <a class="external" href="http://www.gnu.org/software/textutils/textutils.html">GNU Textutils</a>. Windows users can get binary md5 programs from <a class="external" href="http://www.fourmilab.ch/md5/">here</a>, <a class="external" href="http://www.pc-tools.net/win32/freeware/console/">here</a>, or <a class="external" href="http://www.slavasoft.com/fsum/">here</a>.</p>
+<p>We strongly recommend that you verify your downloads with both PGP and MD5.</p>
