+
+Compatibility notes:
+
+Access to class constructors (i.e. `({}).constructor`) is now prohibited to prevent
+Remote Code Execution. This means that following construct will no work anymore:
+
+```
+class SomeClass {
+}
+
+SomeClass.staticProperty = 'static'
+
+var template = Handlebars.compile('{{constructor.staticProperty}}');
+document.getElementById('output').innerHTML = template(new SomeClass());
+// expected: 'static', but now this is empty.
+```
+
+This kind of access is not the intended use of Handlebars and leads to the vulnerability described in #1495. We will **not** increase the major version, because such use is not intended or documented, and because of the potential impact of the issue (we fear that most people won't use a new major version and the issue may not be resolved on many systems).
