 ### Added
 
-- added separate async process that fetches new voting_anchors, validates their metadata using metadata-validation service, and then stores it in Redis database [Issue 1234](https://github.com/IntersectMBO/govtool/issues/1234)
 - added `bio` `dRepName` `email` `references` `metadataValid` and `metadataStatus` fields to `drep/list`
 - added `metadatavalidationmaxconcurrentrequests` field to the backend config
 - added `metadata/validate` endpoint [Issue 876](https://github.com/IntersectMBO/govtool/issues/876)

 ### Changed
 
-- `redis` config fields changed [Issue 1234](https://github.com/IntersectMBO/govtool/issues/1234)
 - `proposal.about` changed to `proposal.abstract`
 - `drep/info` now returns 4 different tx hashes instead of one latest tx hash [Issue 688](https://github.com/IntersectMBO/govtool/issues/688)
 - `proposal/list` allows user to search by tx hash [Issue 603](https://github.com/IntersectMBO/govtool/issues/603)
