 # Changelog
 
-## 1.6.0 (TBD)
-
-### New features
-
-- Certificate handlebar for registration fees `registrationFees` [#6817](https://github.com/opencrvs/opencrvs-core/issues/6817)
-- Logged in user details handlebar `loggedInUser` [#6529](https://github.com/opencrvs/opencrvs-core/issues/6529)
-- Supporting document fields can now be made required
-- If there is only one option in the document uploader select, then it stays hidden and only the upload button is showed with the only option being selected by default
-
-- #### ElasticSearch reindexing
-
-  Allows reindexing ElasticSearch via a new search-service endpoint `reindex`. We're replacing the original `ocrvs` index with timestamped ones. This is done automatically when upgrading and migrating, but this is an important architectural change that should be noted. More details in [#7033](https://github.com/opencrvs/opencrvs-core/pull/7033).
-
-- Introduce a new certificate handlebar "preview" which can be used to conditionally render some svg element when previewing the certificate e.g. background image similar to security paper
-
-### Improvements
-
-- Internally we were storing the `family` name field as a required property which was limiting what how you could capture the name of a person in the forms. Now we are storing it as an optional property which would make more flexible.
-
-### Breaking changes
-
-- Remove `DEL /elasticIndex` endpoint due reindexing changes.
-- Gateways searchEvents `operationHistories` only returns `operationType` & `operatedOn` due to the other fields being unused in OpenCRVS
-- Core used to provide review/preview section by default which are now removed and need to be provided from countryconfig. The signature field definitions (e.g. informant signature, bride signature etc.) were hard coded in core which also have now been removed. The signatures can now be added through the review/preview sections defined in countryconfig just like any other field. You can use the following section definition as the default which is without any additional fields. We highly recommend checking out our reference country repository which has the signature fields in it's review/preview sections
