 # Version 0.25.0 [2020-09-09]
 
+- Remove the deprecated `libp2p-secio` dependency. To continue to use
+  SECIO, add an explicit dependency on `libp2p-secio`. However,
+  transitioning to `libp2p-noise` is strongly recommended.
+
 - Update `libp2p-yamux` to `0.22.0`. *This version starts a multi-release
   upgrade process.* See the `libp2p-yamux` CHANGELOG for details.
