@@ -30,6 +30,15 @@ for people who forked CometBFT and interact directly with the indexers kvstore.
 - `[kvindexer]` Added support for big integers and big floats in the kvindexer.
   Breaking changes: function `Number` in package `libs/pubsub/query/syntax` changed its return value.
   ([\#797](https://github.com/cometbft/cometbft/pull/797))
+- `[mempool]` Application can now set `ConsensusParams.Block.MaxBytes` to -1
+  to have visibility on all transactions in the
+  mempool at `PrepareProposal` time.
+  This means that the total size of transactions sent via `RequestPrepareProposal`
+  might exceed `RequestPrepareProposal.max_tx_bytes`.
+  If that is the case, the application MUST make sure that the total size of transactions
+  returned in `ResponsePrepareProposal.txs` does not exceed `RequestPrepareProposal.max_tx_bytes`,
+  otherwise CometBFT will panic.
+  ([\#980](https://github.com/cometbft/cometbft/issues/980))
 - `[state]` Move pruneBlocks from node/state to state/execution.

 - `[pubsub/kvindexer]` Numeric query conditions and event values are represented as big floats with default precision of 125.
   Integers are read as "big ints" and represented with as many bits as they need when converting to floats.
   ([\#797](https://github.com/cometbft/cometbft/pull/797))
+- `[node]` Make handshake cancelable ([cometbft/cometbft\#857](https://github.com/cometbft/cometbft/pull/857))
+- `[mempool]` Application can now set `ConsensusParams.Block.MaxBytes` to -1
+  to gain more control on the max size of transactions in a block.
