+## v2.20.0 - 2024-06-05
+### Fixed
+* ([#170](https://gitlab.com/Chill-Projet/chill-bundles/-/issues/170)) Display agents traitants instead of accompanying period referrer in export list social actions.
+* Added translations for choices of durations (> 5 hours)
+### Feature
+* ([#145](https://gitlab.com/Chill-Projet/chill-bundles/-/issues/145)) Allow to open documents in LibreOffice locally (need configuration within security);
+
+  This endpoint should be added to make the endpoint works properly:
+
+  ```yaml
+  security:
+      firewalls:
+          dav:
+               pattern: ^/dav
+               provider: chain_provider
+               stateless: true
+               guard:
+                   authenticators:
+                       - Chill\DocStoreBundle\Security\Guard\JWTOnDavUrlAuthenticator
+
+  ```
