 ### Fixed
 
-* Template lookup in nested use cases (#61)  
+* Template lookup in nested use cases (#61)
   Template lookup used to be done on the whole HTML document so add triggers can be declared anywhere inside or outside a Cocooned container. In nested use cases, this could lead to incorrect template being used to build grand-child items when multiple child items had been built since the last form save. Lookup is now done first inside the closest Cocooned item if any to ensure the correct template will be used.
 
 ## Version 2.1.0 (2024-01-28)
 
 ### Added
 
-* Add support for custom tag name to container helpers (#55, #56)  
-  `cocooned_container` and `cocooned_item` now support an optional tag name as their first argument (as `content_tag` do) when the default `<div/>` is not appropriate.

+  `cocooned_container` and `cocooned_item` now support an optional tag name as their first argument (as `content_tag` do) when the default `<div/>` is not appropriate.
   **Warning:** This change is not supposed to break anything as helpers prototypes stays the same and no other positional argument where really expected before. However, depending on how you used these helpers with previous releases, you may encounter unexpected side effects.
 * Documentation about nested use cases and event initialization (#59)

-* Replacements operated on a newly built item in some nested use cases (#52, #57)  
+* Replacements operated on a newly built item in some nested use cases (#52, #57)
   Replacements are now done recursively in nested templates if any exists. This should fix field naming in newly built items when multiple Cocooned instance are nested and correct naming of sub-items depends on generated names for their parent.
