+
+INFO FOR PEOPLE ADDING CHANGES:
+
+Check the DTD (apichanges.dtd) for details on the syntax. You do not
+need to regenerate the HTML, this will be done periodically; just
+change the XML. If you can, validate the XML against the DTD, if not
+do not worry about it. Rough syntax of a change (several parts optional):
+
+<change>
+    <api name="compiler"/>
+    <summary>Some brief description here, can use <b>XHTML</b></summary>
+    <version major="1" minor="99"/>
+    <date day="13" month="6" year="2001"/>
+    <author login="jrhacker"/>
+    <compatibility addition="yes"/>
+    <description>
+        The main description of the change here.
+        Again can use full <b>XHTML</b> as needed.
+    </description>
+    <class package="org.openide.compiler" name="DoWhatIWantCompiler"/>
+    <issue number="14309"/>
+</change>
+
+Also permitted elements: <package>, <branch>. <version> is API spec
+version, recommended for all new changes. <compatibility> should say
+if things were added/modified/deprecated/etc. and give all information
+related to upgrading old code. List affected top-level classes and
+link to issue numbers if applicable. See the DTD for more details.
+
+Changes need not be in any particular order, they are sorted in various
+ways by the stylesheet anyway.
+
+Dates are assumed to mean "on the trunk". If you *also* make the same
+change on a stabilization branch, use the <branch> tag to indicate this
+and explain why the change was made on a branch in the <description>.
+
+Please only change this file on the trunk! Rather: you can change it
+on branches if you want, but these changes will be ignored; only the
+trunk version of this file is important.
+
+Deprecations do not count as incompatible, assuming that code using the
+deprecated calls continues to see their documented behavior. But do
+specify deprecation="yes" in <compatibility>.
+
+This file is not a replacement for Javadoc: it is intended to list changes,
+not describe the complete current behavior, for which ordinary documentation
+is the proper place.

+<h1>Introduction</h1>
+
+<h2>What do the Dates Mean?</h2>
+
+<p>The supplied dates indicate when the API change was made, on the CVS
+trunk. From this you can generally tell whether the change should be
+present in a given build or not; for trunk builds, simply whether it
+was made before or after the change; for builds on a stabilization
+branch, whether the branch was made before or after the given date. In
+some cases corresponding API changes have been made both in the trunk
+and in an in-progress stabilization branch, if they were needed for a
+bug fix; this ought to be marked in this list.</p>
