# Changelog
## 0.4.0 (March 6, 2017)
BREAKING CHANGES:
- Query takes RequestQuery and returns ResponseQuery, with more specificity over keys, paths, and proofs:
```
message RequestQuery{
bytes data = 1;
string path = 2;
uint64 height = 3;
bool prove = 4;
}
message ResponseQuery{
CodeType code = 1;
int64 index = 2;
bytes key = 3;
bytes value = 4;
bytes proof = 5;
uint64 height = 6;
string log = 7;
}
```
IMPROVEMENTS:
- Updates to Makefile
- Various cleanup
- BaseApplication can be embedded by new apps to avoid implementing empty methods
- Drop BlockchainAware and make BeginBlock/EndBlock part of the `type Application interface`
## 0.3.0 (January 12, 2017)
BREAKING CHANGES:
- TMSP is now ABCI (Application/Asynchronous/A BlockChain Interface or Atomic BroadCast Interface)
- AppendTx is now DeliverTx (conforms to the literature)
- BeginBlock takes a Header:
```
message RequestBeginBlock{
bytes hash = 1;
Header header = 2;
}
```
- Info returns a ResponseInfo, containing last block height and app hash:o
```
message ResponseInfo {
string data = 1;
string version = 2;
uint64 last_block_height = 3;
bytes last_block_app_hash = 4;
}
```
- EndBlock returns a ResponseEndBlock, containing the changed validators:
```
message ResponseEndBlock{
repeated Validator diffs = 4;
}
```
- Hex strings are 0x-prefixed in the CLI
- Query on the Dummy app now uses hex-strings
FEATURES:
- New app, PersistentDummy, uses Info/BeginBlock to recover from failures and supports validator set changes
- New message types for blockchain data:
```
//----------------------------------------
// Blockchain Types
message Header {
string chain_id = 1;
uint64 height = 2;
uint64 time = 3;
uint64 num_txs = 4;
BlockID last_block_id = 5;
bytes last_commit_hash = 6;
bytes data_hash = 7;
bytes validators_hash = 8;
bytes app_hash = 9;
}
message BlockID {
bytes hash = 1;
PartSetHeader parts = 2;
}
message PartSetHeader {
uint64 total = 1;
bytes hash = 2;
}
message Validator {
bytes pubKey = 1;
uint64 power = 2;
}
```
- Add support for Query to Counter app
IMPROVEMENT:
- Don't exit the tmsp-cli console on bad args
BUG FIXES:
- Fix parsing in the Counter app to handle invalid transactions
## 0.2.1 (September 12, 2016)
IMPROVEMENTS
- Better error handling in console
## 0.2.0 (July 23, 2016)
BREAKING CHANGES:
- Use `oneof` types in protobuf
FEATURES:
- GRPC support
