+# Migrating to version 5
+
+In version 5, we now export two different types of schemas, one using `$id` feature in JSON Schema, and one without.
+
+In v4, the library would export the schemas as:
+```js
+module.exports = {
+  '2.0.0': require('./schemas/2.0.0.json'),
+  ...
+};
+```
+
+In v5, you need to access the schemas through `.schemas` instead.
+
+```js
+module.exports = {
+    'schemas': {
+        '2.0.0': require('./schemas/2.0.0.json'),
+        ...
+    },
+    'schemasWithoutId': {
+        '2.0.0': require('./schemas/2.0.0-without-$id.json'),
+        ...
+    }
+};
+```
+
+And if you want the schemas without `$id`, use `schemasWithoutId`.

+# Migrating to version 6
+
+In version 6 and onwards, all pre-release AsyncAPI specification versions will be released as a regular feature request, before the AsyncAPI specification itself is released.
+
+The pre-release version will be released as if it was not a pre-release, for example for AsyncAPI 3.0, it will be released as normal:
+```js
+module.exports = {
+    'schemas': {
+        ...
+        '3.0.0': require('./schemas/3.0.0.json'),
+    },
+    'schemasWithoutId': {
+        ...
+        '3.0.0': require('./schemas/3.0.0-without-$id.json'),
+    }
+};
+```
+
+However, while it's still a pre-release, the underlying schemas CAN contain breaking changes from version to version, up until the AsyncAPI specification is released. This means that one AsyncAPI document using v3 in the pre-release stage might be valid in `6.0.0`, but invalid in the `6.1.0`. This ONLY applies to pre-release schemas, and NOT regular ones that are set in stone.
+
+If you want to make sure you don't use a schema not released yet, you have to whitelist which versions you allow in your tool.
