# Changelog
## v0.31.4
*April 12th, 2019*
This release fixes a regression from v0.31.3 which used the peer's `SocketAddr` to add the peer to
the address book. This swallowed the peer's self-reported port which is important in case of reconnect.
It brings back `NetAddress()` to `NodeInfo` and uses it instead of `SocketAddr` for adding peers.
Additionally, it improves response time on the `/validators` or `/status` RPC endpoints.
As a side-effect it makes these RPC endpoint more difficult to DoS and fixes a performance degradation in `ExecCommitBlock` .
Also, it contains an [ADR ](https://github.com/tendermint/tendermint/pull/3539 ) that proposes decoupling the
responsibility for peer behaviour from the `p2p.Switch` (by @brapse ).

### IMPROVEMENTS:
- [p2p] [\#3463 ](https://github.com/tendermint/tendermint/pull/3463 ) Do not log "Can't add peer's address to addrbook" error for a private peer
- [p2p] [\#3547 ](https://github.com/tendermint/tendermint/pull/3547 ) Fix a couple of annoying typos (@mdyring)
### BUG FIXES:
- [docs] [\#3514 ](https://github.com/tendermint/tendermint/issues/3514 ) Fix block.Header.Time description (@melekes)
- [p2p] [\#2716 ](https://github.com/tendermint/tendermint/issues/2716 ) Check if we're already connected to peer right before dialing it (@melekes)
- [p2p] [\#3545 ](https://github.com/tendermint/tendermint/issues/3545 ) Add back `NetAddress()` to `NodeInfo` and use it instead of peer's `SocketAddr()` when adding a peer to the `PEXReactor` (potential fix for [\#3532 ](https://github.com/tendermint/tendermint/issues/3532 ))
- [state] [\#3438 ](https://github.com/tendermint/tendermint/pull/3438 )
Persist validators every 100000 blocks even if no changes to the set
occurred (@guagualvcha). This
1) Prevents possible DoS attack using `/validators` or `/status` RPC
endpoints. Before response time was growing linearly with height if no
changes were made to the validator set.
2) Fixes performance degradation in `ExecCommitBlock` where we call
`LoadValidators` for each `Evidence` in the block.
## v0.31.3
*April 1st, 2019*
@ -8,6 +41,12 @@ This release includes two security sensitive fixes: it ensures generated private
keys are valid, and it prevents certain DNS lookups that would cause the node to
panic if the lookup failed.
### BREAKING CHANGES:
* Go API
- [crypto/secp256k1] [\#3439 ](https://github.com/tendermint/tendermint/issues/3439 )
The `secp256k1.GenPrivKeySecp256k1` function has changed to guarantee that it returns a valid key, which means it
will return a different private key than in previous versions for the same secret.
