+<h2>New features</h2>
+
+<p>
+ AspectJ 1.9.9 supports <a href="https://openjdk.java.net/projects/jdk/18/">Java 18</a> and its final and preview
+ features, such as:
+</p>
+<ul>
+ <li>Pattern matching for <tt>switch</tt> (preview 2)</li>
+</ul>
+
+<h2>Improvements</h2>
+
+<h2>Code examples</h2>
+
+<p>
+ You can find some sample code in the AspectJ test suite under the respective AspectJ version in which the features
+ were first supported (possibly as JVM preview features):
+</p>
+<ul>
+ <li>
+ <a href="https://github.com/eclipse/org.aspectj/tree/master/tests/features198/java17">
+ Pattern matching for switch, preview 1

+ <a href="https://github.com/eclipse/org.aspectj/tree/master/tests/features199/java18">
+ Pattern matching for switch, preview 2
+ </a>
+ </li>
+</ul>
+
+<h2>Other changes and bug fixes</h2>
+
+<ul>
+ <li>
+ Fix a bug which led to <tt>NullPointerException</tt>s if too many JAR archives were on the classpath. Too many here
+ means the value system property <tt>org.aspectj.weaver.openarchives</tt> (1,000 by default). The AspectJ compiler is
+ meant to close archives upon cache exhaustion and then re-open them if it needs them again later. Re-opening was
+ broken, now the compiler works reliably even for cache sizes as small as 20. See issue
+ <a href="https://github.com/eclipse/org.aspectj/issues/125">#125</a>.

+<h2>AspectJ usage hints</h2>
+
+<h3>AspectJ compiler build system requirements</h3>
+
+<p>
+ Since 1.9.7, the AspectJ compiler <tt>ajc</tt> (contained in the <tt>aspectjtools</tt> library) no longer works on
+ JDKs 8 to 10. The minimum compile-time requirement is now JDK 11 due to upstream changes in the Eclipse Java Compiler
+ (subset of JDT Core), which AspectJ is a fork of. You can still compile to legacy target versions as low as Java 1.3
+ when compiling plain Java code or using plain Java ITD constructs which do not require the AspectJ runtime
+ <tt>aspectjrt</tt>, but the compiler itself needs JDK 11+. Just like in previous AspectJ versions, both the runtime
+ <tt>aspectjrt</tt> and the load-time weaver <tt>aspectjweaver</tt> still only require JRE 8+.
+</p>
+
+<h3>Use LTW on Java 16+</h3>
+
+<p>
+ Please note that if you want to use load-time weaving on Java 16+, the weaving agent collides with
+ <a href="https://openjdk.java.net/jeps/396">JEP 396 (Strongly Encapsulate JDK Internals by Default)</a> and related
+ subsequent JEPs. Therefore, you need to set the JVM parameter <tt>--add-opens java.base/java.lang=ALL-UNNAMED</tt> in
+ order to enable aspect weaving. This is due to the fact that the weaver uses internal APIs for which we have not found
+ an adequate replacement yet when defining classes in different classloaders.
+</p>
+
+<h3>Compile with Java preview features</h3>
+
+<p>
+ For features marked as preview on a given JDK, you need to compile with <tt>ajc --enable-preview</tt> and run with
+ <tt>java --enable-preview</tt> on that JDK.
+</p>
+<p>
+ Please note that you cannot run code compiled with preview features on any other JDK than the one used for
+ compilation. For example, records compiled with preview on JDK 15 cannot be used on JDK 16 without recompilation. This
+ is a JVM limitation unrelated to AspectJ. Also, e.g. sealed classes are preview-1 on JDK 15 and preview-2 on JDK 16.
+ You still need to recompile, no matter what.
