- Any configuration option now within a substract must come under that heading in the `config.toml`, for instance:
```
[p2p]
laddr="tcp://1.2.3.4:46656"
[consensus]
timeout_propose=1000
```
- Use viper and `DefaultConfig() / `TestConfig()` functions to handle defaults, and remove `config/tendermint` and `config/tendermint_test`
- Change some function and method signatures to accomodate new config: https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b for comprehensive list.
- Replace static `log15` logger with a simple interface, and provide a new implementation using `go-kit`.
tSee our [blog post](https://tendermint.com/blog/abstracting-the-logger-interface-in-go) for more details
- Levels `warn` and `notice` are removed (you may need to change them in your `config.toml`!)
- Change some function and method signatures to accept a logger: https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b for comprehensive list.
- JSON serialization:
- Replace `[TypeByte, Xxx]` with `{"type": "some-type", "data": Xxx}` in RPC and all `.json` files by using `go-wire/data`. For instance, a public key is now:
```
"pub_key": {

}
```
- New config
- Isolate viper to `cmd/tendermint/commands`
- New Config structs in `config/`: `BaseConfig`, `P2PConfig`, `MempoolConfig`, `ConsensusConfig`
- Remove config/tendermint and config/tendermint_test. Defaults are handled by viper and `DefaultConfig() / `TestConfig()` functions
- Tests do not read config from file
- New logger (`github.com/tendermint/tmlibs/log`)
- Reduced to three levels: `error`, `info`, and `debug`
- NOTE: The default in previous versions was `notice`, which is no longer valid. Please change it in the `config.toml`
- Per-module log levels
- The new default is `state:info,*:error`, which means the `state` package logs at `info` level, and everything else logs at `error` level
- No global loggers (loggers are passed into constructors, or preferably set with a `SetLogger` method)
- RPC serialization cleanup:
- Lowercase json names for ValidatorSet fields
- No longer uses go-wire, so no more `[TypeByte, XXX]` madness
- Responses have no type information
- Remove type information about RPC responses, so `[TypeByte, {"jsonrpc": "2.0", ... }]` is now just `{"jsonrpc": "2.0", ... }`
- Change `[]byte` to `data.Bytes` in all serialized types (for hex encoding)
- Lowercase the JSON tags in `ValidatorSet` fields
- Introduce EventDataInner for serializing events
- Remove all use of go-wire (and `[TypeByte, XXX]`) in the `genesis.json` and `priv_validator.json`
- [consensus/abci] Send InitChain message in handshake if `appBlockHeight == 0`
- [types] `[]byte -> data.Bytes`
- [types] Do not include the `Accum` field when computing the hash of a validator. This makes the ValidatorSetHash unique for a given validator set, rather than changing with every block (as the Accum changes)
- A number of functions and methods ahd their signatures modified to accomodate new config and logger. See https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b for comprehensive list. Note many also had `[]byte` arguments changed to `data.Bytes`, but this is not actually breaking.
- Other:
- Send InitChain message in handshake if `appBlockHeight == 0`
- Do not include the `Accum` field when computing the validator hash. This makes the ValidatorSetHash unique for a given validator set, rather than changing with every block (as the Accum changes)
- Unsafe RPC calls are not enabled by default. This includes `/dial_seeds`, and all calls prefixed with `unsafe`. Use the `--rpc.unsafe` flag to enable.
FEATURES:
- Per-module log levels. For instance, the new default is 'state:info,*:error', which means the `state` package logs at `info` level, and everything else logs at `error` level
- Log if a node is validator or not in every consensus round
- Use ldflags to set git hash as part of the version
- Ignore `address` and `pub_key` fields in `priv_validator.json` and overwrite them with the values derrived from the `priv_key`

- `go-data -> go-wire/data`

- RPC JSON responses use pretty printing (via `json.MarshalIndent`)
- Color code different instances of the consensus for tests
- Isolate viper to `cmd/tendermint/commands` and do not read config from file for tests
