+## Migration
+
+## Version 7
+
+The `message` parameter to `TypedError` is now
+required. Previously `message` was optional
+for `TypedError`.
+
+## Version 6
+
+The `WrappedError` class now exposes the error that
+is being wrapped as a `cause` field instead of an
+`original` field.
+
+The following properties have been reserver on the
+wrapped error class: `cause`, `fullType`, `causeMessage`
+
+## Version 5
+
+There were no breaking changes...
+
+## Version 4
+
+The `TypedError` function now has mandatory arguments.
+The `type` and `message` arguments for `TypedError`
+are required.
+
+## Version 3
+
+The `TypedError` class now uses `string-template` for
+message formatting.
+
+Previously:
+
+```js
+var FooError = TypedError({
+  type: 'foo.x'
+  message: 'Got an error %s'
+});
+
+FooError('Oops');
+```
+
+Currently:
+
+```js
+var FooError = TypedError({
+  type: 'foo.x',
+  message: 'Got an error {ctx}',
+  ctx: null
+});
+
+FooError({ ctx: 'Oops' });
+```
+
+## Version 2
+
+Original version

+
+## Wrapped Errors
+
+```js
+var net = require('net');
+var WrappedError = require('error/wrapped');
+
+var ServerListenError = WrappedError({
+    message: 'server: {origMessage}',
+    type: 'server.listen-failed',

+
+var server = net.createServer();
