+## GrimoireLab 0.21.0 - (2024-02-19)
+
+**New components:**
+
+* sortinghat 0.20.0
+* perceval-mozilla 0.4.0
+* grimoire-elk 0.109.8
+* sirmordred 0.10.8
+
+The following list describes the changes by component:
+
+### sortinghat
+
+**New features:**
+
+ * Organization aliases (#857)\
+   Organizations can be known by different names. To avoid duplicates,
+   organizations can have aliases. Searching for an organization using
+   one of its aliases returns the organization. When an organization is
+   merged into another, its name becomes an alias of the target
+   organization. If a name exists as an alias, no organization can be
+   created with that name and viceversa. An organization's aliases can be
+   added and deleted both on the organizations table and the single
+   organization view.
+
+### perceval-mozilla
+
+**New features:**
+
+ * Retry Kitsune when rate limited\
+   Kitsune now includes the `--sleep-for-rate` option to manage `429 Too
+   Many Requests` errors. You can configure retries and sleep duration
+   using the `--max-retries` and `--sleep-time` options respectively.
