+# 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
+
+
