+
+FEATURES:

+
+## 0.10.3 (August 10, 2017)

+  - new flag, `--consensus.create_empty_blocks`; when set to false, blocks are only created when there are txs or when the AppHash changes.
+  - new config option, `consensus.create_empty_blocks_interval`; an empty block is created after this many seconds.
+  - in normal operation, `create_empty_blocks = true` and `create_empty_blocks_interval = 0`, so blocks are being created all the time (as in all previous versions of tendermint). The number of empty blocks can be reduced by increasing `create_empty_blocks_interval` or by setting `create_empty_blocks = false`.
+  - new `TxsAvailable()` method added to Mempool that returns a channel which fires when txs are available.
+  - new heartbeat message added to consensus reactor to notify peers that a node is waiting for txs before entering propose step.

+    - `--node_laddr` is now `--p2p.laddr`
+    - `--pex` is now `--p2p.pex`
+    - `--skip_upnp` is now `--p2p.skip_upnp`
+    - `--rpc_laddr` is now `--rpc.laddr`
+    - `--grpc_laddr` is now `--rpc.grpc_laddr`
+  - 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
+  - Change some [function and method signatures](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) accomodate new config
+
+- Logger
+  - Replace static `log15` logger with a simple interface, and provide a new implementation using `go-kit`.
+See our new [logging library](https://github.com/tendermint/tmlibs/log) and [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](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) to accept a logger
+
+- 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": {
+      "type": "ed25519",
+      "data": "83DDF8775937A4A12A2704269E2729FCFCD491B933C4B0A7FFE37FE41D7760D0"
+    }
+    ```
+  - 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
+
+- 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`
+
+IMPROVEMENTS:
+
+- Merge `tendermint/go-p2p -> tendermint/tendermint/p2p` and `tendermint/go-rpc -> tendermint/tendermint/rpc/lib`
+- Update paths for grand repo merge:
+  - `go-common -> tmlibs/common`
+  - `go-data -> go-wire/data`
+  - All other `go-` libs, except `go-crypto` and `go-wire`, are merged under `tmlibs`
+- No global loggers (loggers are passed into constructors, or preferably set with a SetLogger method)
+- Return HTTP status codes with errors for RPC responses
+- Limit `/blockchain_info` call to return a maximum of 20 blocks
+- Use `.Wrap()` and `.Unwrap()` instead of eg. `PubKeyS` for `go-crypto` types
+- 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
+
+
+## 0.9.2 (April 26, 2017)
+
+BUG FIXES:
+
+- Fix bug in `ResetPrivValidator` where we were using the global config and log (causing external consumers, eg. basecoin, to fail).
+
+## 0.9.1 (April 21, 2017)
+
+FEATURES:
+
+- Transaction indexing - txs are indexed by their hash using a simple key-value store; easily extended to more advanced indexers
+- New `/tx?hash=X` endpoint to query for transactions and their DeliverTx result by hash. Optionally returns a proof of the tx's inclusion in the block
+- `tendermint testnet` command initializes files for a testnet
+
+IMPROVEMENTS:
+
+- CLI now uses Cobra framework
+- TMROOT is now TMHOME (TMROOT will stop working in 0.10.0)
+- `/broadcast_tx_XXX` also returns the Hash (can be used to query for the tx)
+- `/broadcast_tx_commit` also returns the height the block was committed in
+- ABCIResponses struct persisted to disk before calling Commit; makes handshake replay much cleaner
+- WAL uses #ENDHEIGHT instead of #HEIGHT (#HEIGHT will stop working in 0.10.0)
+- Peers included via `--seeds`, under `seeds` in the config, or in `/dial_seeds` are now persistent, and will be reconnected to if the connection breaks
+
+BUG FIXES:
+
+- Fix bug in fast-sync where we stop syncing after a peer is removed, even if they're re-added later
+- Fix handshake replay to handle validator set changes and results of DeliverTx when we crash after app.Commit but before state.Save()
+
+## 0.9.0 (March 6, 2017)
+
+BREAKING CHANGES:
+
+- Update ABCI to v0.4.0, where Query is now `Query(RequestQuery) ResponseQuery`, enabling precise proofs at particular heights:
+
+```
+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;
+}
+```
+
+
+- `BlockMeta` data type unifies its Hash and PartSetHash under a `BlockID`:
+
+```
+type BlockMeta struct {
+	BlockID BlockID `json:"block_id"` // the block hash and partsethash
+	Header  *Header `json:"header"`   // The block's Header
+}
+```
+
+- `ValidatorSet.Proposer` is exposed as a field and persisted with the `State`. Use `GetProposer()` to initialize or update after validator-set changes.
+
+- `tendermint gen_validator` command output is now pure JSON
+
+FEATURES:
+
+- New RPC endpoint `/commit?height=X` returns header and commit for block at height `X`

+
+IMPROVEMENTS:
+
+- `Node` is now a `BaseService`
+- Simplified starting Tendermint in-process from another application
+- Better organized Makefile
+- Scripts for auto-building binaries across platforms

+- Improvements on CircleCI for managing build/test artifacts
+- Handshake replay is doen through the consensus package, possibly using a mockApp
+- Graceful shutdown of RPC listeners
+- Tests for the PEX reactor and DialSeeds
+
+BUG FIXES:
+
+- Check peer.Send for failure before updating PeerState in consensus
+- Fix panic in `/dial_seeds` with invalid addresses
+- Fix proposer selection logic in ValidatorSet by taking the address into account in the `accumComparable`
+- Fix inconcistencies with `ValidatorSet.Proposer` across restarts by persisting it in the `State`
+
+
+## 0.8.0 (January 13, 2017)
+
+BREAKING CHANGES:
+
+- New data type `BlockID` to represent blocks:
+
+```
+type BlockID struct {
+	Hash        []byte        `json:"hash"`
+	PartsHeader PartSetHeader `json:"parts"`
+}
+```
+
+- `Vote` data type now includes validator address and index:
+
+```
+type Vote struct {
+	ValidatorAddress []byte           `json:"validator_address"`
+	ValidatorIndex   int              `json:"validator_index"`
+	Height           int              `json:"height"`
+	Round            int              `json:"round"`
+	Type             byte             `json:"type"`
+	BlockID          BlockID          `json:"block_id"` // zero if vote is nil.
+	Signature        crypto.Signature `json:"signature"`
+}
+```
+
+- Update TMSP to v0.3.0, where it is now called ABCI and AppendTx is DeliverTx
+- Hex strings in the RPC are now "0x" prefixed
+
+
+FEATURES:
+
+- New message type on the ConsensusReactor, `Maj23Msg`, for peers to alert others they've seen a Maj23,
+in order to track and handle conflicting votes intelligently to prevent Byzantine faults from causing halts:
+
+```
+type VoteSetMaj23Message struct {
+	Height  int
+	Round   int
+	Type    byte
+	BlockID types.BlockID
+}
+```
+
+- Configurable block part set size
+- Validator set changes
+- Optionally skip TimeoutCommit if we have all the votes
+- Handshake between Tendermint and App on startup to sync latest state and ensure consistent recovery from crashes

+
+## PreHistory
+
+Strict versioning only began with the release of v0.7.0, in late summer 2016.
+The project itself began in early summer 2014 and was workable decentralized cryptocurrency software by the end of that year.
+Through the course of 2015, in collaboration with Eris Industries (now Monax Indsutries),
+many additional features were integrated, including an implementation from scratch of the Ethereum Virtual Machine.
+That implementation now forms the heart of [Burrow](https://github.com/hyperledger/burrow).
+In the later half of 2015, the consensus algorithm was upgraded with a more asynchronous design and a more deterministic and robust implementation.
+
+By late 2015, frustration with the difficulty of forking a large monolithic stack to create alternative cryptocurrency designs led to the
+invention of the Application Blockchain Interface (ABCI), then called the Tendermint Socket Protocol (TMSP).
+The Ethereum Virtual Machine and various other transaction features were removed, and Tendermint was whittled down to a core consensus engine
+driving an application running in another process.
+The ABCI interface and implementation were iterated on and improved over the course of 2016,
+until versioned history kicked in with v0.7.0.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+
+Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language -
+and securely replicates it on many machines.
+
+For protocol details, see [the specification](/docs/spec).
+
+## A Note on Production Readiness
+
+While Tendermint is being used in production in private, permissioned
+environments, we are still working actively to harden and audit it in preparation
+for use in public blockchains, such as the [Cosmos Network](https://cosmos.network/).
+We are also still making breaking changes to the protocol and the APIs.
+Thus we tag the releases as *alpha software*.
+
+In any case, if you intend to run Tendermint in production,
+please [contact us](https://riot.im/app/#/room/#tendermint:matrix.org) :)
+

+
+## Versioning
+
+### SemVer
+
+Tendermint uses [SemVer](http://semver.org/) to determine when and how the version changes.
+According to SemVer, anything in the public API can change at any time before version 1.0.0
+
+To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used
+to signal breaking changes across a subset of the total public API. This subset includes all
+interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not
+include the in-process Go APIs.
+
+That said, breaking changes in the following packages will be documented in the
+CHANGELOG even if they don't lead to MINOR version bumps:
+
+- types
+- rpc/client
+- config
+- node
+
+Exported objects in these packages that are not covered by the versioning scheme
+are explicitly marked by `// UNSTABLE` in their go doc comment and may change at any time.
+Functions, types, and values in any other package may also change at any time.
+
+### Upgrades
+
+In an effort to avoid accumulating technical debt prior to 1.0.0,
+we do not guarantee that breaking changes (ie. bumps in the MINOR version)
+will work with existing tendermint blockchains. In these cases you will
+have to start a new blockchain, or write something custom to get the old
+data into the new chain.
+
+However, any bump in the PATCH version should be compatible with existing histories
+(if not please open an [issue](https://github.com/tendermint/tendermint/issues)).
