+          <p>The <c>disk_log</c> module has been slightly changed for
+            the purpose of reducing the risk of memory problems due
+            to corrupt files. The <c>chunk</c> commands have been
+            optimized by increasing the chunk size from 8 kilobytes
+            to 64 kilobytes.</p>

+          <p>When loading a dynamically linked in driver through
+            <c>erl_ddll</c>, the server <c>ddll_server</c> that held
+            the port for the driver handling shared libraries got
+            the group leader of the invoking application. Later, when
+            the application was terminated, it killed all processes in
+            its group, also the <c>ddll_server</c>, so the driver still
+            had some shared libraries loaded. Finally, when

+            shared libraries its driver knew of was statically linked,
+            so the dynamically linked in drivers that was loaded when
+            <c>ddll_server</c> was killed could neither be loaded nor
+            unloaded. This bug has now been fixed by setting the group
+            leader of <c>ddll_server</c> to something harmless and more
+            eternal, and by unloading all remaining dynamically linked
+            in drivers when <c>ddll_server</c> starts. A race condition
