 ## [Unreleased]
 
 ## Features
-
+* [\#8965](https://github.com/cosmos/cosmos-sdk/pull/8965) cosmos reflection now provides more information on the application such as: deliverable msgs, sdk.Config info etc.
 * [\#8559](https://github.com/cosmos/cosmos-sdk/pull/8559) Added Protobuf compatible secp256r1 ECDSA signatures.
 * [\#8786](https://github.com/cosmos/cosmos-sdk/pull/8786) Enabled secp256r1 in x/auth.
 * (rosetta) [\#8729](https://github.com/cosmos/cosmos-sdk/pull/8729) Data API fully supports balance tracking. Construction API can now construct any message supported by the application.
 * [\#8754](https://github.com/cosmos/cosmos-sdk/pull/8875) Added support for reverse iteration to pagination.
 
 ### Client Breaking Changes
-
+* [\#8965](https://github.com/cosmos/cosmos-sdk/pull/8965) Cosmos reflection import path has changed from `github.com/cosmos/cosmos-sdk/client/grpc/reflection` to `github.com/cosmos/cosmos-sdk/server/grpc/appreflection`
 * [\#8363](https://github.com/cosmos/cosmos-sdk/pull/8363) Addresses no longer have a fixed 20-byte length. From the SDK modules' point of view, any 1-255 bytes-long byte array is a valid address.
 * [\#8346](https://github.com/cosmos/cosmos-sdk/pull/8346) All CLI `tx` commands generate ServiceMsgs by default. Graceful Amino support has been added to ServiceMsgs to support signing legacy Msgs.
 * (crypto/ed25519) [\#8690] Adopt zip1215 ed2559 verification rules.
