 ### Notable changes ###
 
 
+#### New optional strict_mode_vouts added to PushTx endpoints ####
+
+A new optional "strict mode" is added to the /pushtx and /pushtx/schedule endpoints of the API.
+
+This strict mode enforces a few additional checks on a selected subset of the outputs of a transaction before it's pushed on the P2P network or before it's scheduled for a delayed push. 
+
+See this [doc](https://code.samourai.io/dojo/samourai-dojo/-/blob/develop/doc/POST_pushtx.md) for detailed information.
