+## v2.1.1 - 2023-02-17
+
+### Fixed
+
+- [[#109](https://github.com/nf-core/nascent/pull/109)] - Fixed bug where using AWS igenomes or passing a pre-made index fails because of an update to the module expects them to have a metamap. Generation was still working.
+
 ## v2.1.0 - 2023-02-15
 
 ### Added
