 ## Unreleased
 
+ - #2622, Consider any PostgreSQL authentication failure as fatal and exit immediately - @michivi
+
+### Added
+
+ - #1414, Add related orders - @steve-chavez
+   + On a many-to-one or one-to-one relationship, you can order a parent by a child column `/projects?select=*,clients(*)&order=clients(name).desc.nullsfirst`
+ - #1233, #1907, #2566, Allow spreading embedded resources - @steve-chavez
+   + On a many-to-one or one-to-one relationship, you can unnest a json object with `/projects?select=*,...clients(client_name:name)`
+   + Allows including the join table columns when resource embedding
+   + Allows disambiguating a recursive m2m embed
+   + Allows disambiguating an embed that has a many-to-many relationship using two foreign keys on a junction
+ - #2340, Allow embedding without selecting any column - @steve-chavez
+ - #2563, Allow `is.null` or `not.is.null` on an embedded resource - @steve-chavez
+   + Offers a more flexible replacement for `!inner`, e.g. `/projects?select=*,clients(*)&clients=not.is.null`
+   + Allows doing an anti join, e.g. `/projects?select=*,clients(*)&clients=is.null`
+   + Allows using or across related tables conditions
+
 ### Fixed
 
  - #2565, Fix bad M2M embedding on RPC - @steve-chavez
