+### BUG FIXES
+
+- `[mempool]` Avoid infinite wait in transaction sending routine when
+  using experimental parameters to limiting transaction gossiping to peers
+  ([\#1654](https://github.com/cometbft/cometbft/pull/1654))
+
+### FEATURES
+
+- `[mempool]` Add `nop` mempool ([\#1643](https://github.com/cometbft/cometbft/pull/1643))
+
+  If you want to use it, change mempool's `type` to `nop`:
+
+  ```toml
+  [mempool]
+
+  # The type of mempool for this node to use.
+  #
+  # Possible types:
+  # - "flood" : concurrent linked list mempool with flooding gossip protocol
+  # (default)
+  # - "nop"   : nop-mempool (short for no operation; the ABCI app is responsible
+  # for storing, disseminating and proposing txs). "create_empty_blocks=false"
+  # is not supported.
+  type = "nop"
+  ```
