+# 3.0.0
+
+* ZfrStripe now uses Guzzle v5 (instead of v3). Usage of ZfrStripe does not change, except that Guzzle 5 is
+substantially faster. This change has introduced a few breaking changes (those are documented in UPGRADING document)

 # 2.8.1
 
 * Add the new `tax_percent` property to subscriptions.

+# From 2.x to 3.x
+
+ZfrStripe 3 upgraded Guzzle from v3 to v5. In this version, iterators have been removed and must be now implemented
+in user-land. ZfrStripe therefore implements a lightweight iterator that replaces previous Guzzle iterator. As a
+consequence, a few things have changed.
+
+The `setPageSize` method has been removed, in favour of explicitly using the standard `limit` parameter from Stripe.
+This makes the client more coherent.
+
+Before:
+
+```php
+$iterator = $stripeClient->getCustomersIterator();
+$iterator->setPageSize(50);
+```
+
+After:
+
+```php
+$iterator = $stripeClient->getCustomersIterator(['limit' => 50]);
+```
+
+The `setLimit` (that was used to limit the **total** number of results) was confusing because it had the same name
+as Stripe `limit` parameter. This method has been removed in favour of a new `setMaxResults` method. For instance,
+to create an iterator that fetch a maximum number of 200 elements, with a limit of 50 elements per API call.
+
+Before:
+
+```php
+$iterator = $stripeClient->getCustomersIterator();
+$iterator->setPageSize(50);
+$iterator->setLimit(200);
+```
+
+After:
+
+```php
+$iterator = $stripeClient->getCustomersIterator(['limit' => 50]);
+$iterator->setMaxResults(200);
