+
+Special thanks to external contributors on this release:
+@fmauricios, @gianfelipe93, @husio, @needkane, @srmo, @yutianwu
+
+This release is primarily about upgrades to the `privval` system -
+separating the `priv_validator.json` into distinct config and data files, and
+refactoring the socket validator to support reconnections.
+
+**Note:** Please backup your existing `priv_validator.json` before using this
+version.
+
+See [UPGRADING.md](UPGRADING.md) for more details.

+
+## v0.27.0
+
+*December 5th, 2018*
+
+Special thanks to external contributors on this release:
+@danil-lashin, @srmo
+
+Special thanks to @dlguddus for discovering a [major
+issue](https://github.com/tendermint/tendermint/issues/2718#issuecomment-440888677)
+in the proposer selection algorithm.
+
+Friendly reminder, we have a [bug bounty
+program](https://hackerone.com/tendermint).
+
+This release is primarily about fixes to the proposer selection algorithm
+in preparation for the [Cosmos Game of
+Stakes](https://blog.cosmos.network/the-game-of-stakes-is-open-for-registration-83a404746ee6).
+It also makes use of the `ConsensusParams.Validator.PubKeyTypes` to restrict the
+key types that can be used by validators, and removes the `Heartbeat` consensus
+message.
+
+### BREAKING CHANGES:
+
+* CLI/RPC/Config
+  - [rpc] [\#2932](https://github.com/tendermint/tendermint/issues/2932) Rename `accum` to `proposer_priority`
+
+* Go API
+  - [db] [\#2913](https://github.com/tendermint/tendermint/pull/2913)
+    ReverseIterator API change: start < end, and end is exclusive.
+  - [types] [\#2932](https://github.com/tendermint/tendermint/issues/2932) Rename `Validator.Accum` to `Validator.ProposerPriority`
+
+* Blockchain Protocol
+  - [state] [\#2714](https://github.com/tendermint/tendermint/issues/2714) Validators can now only use pubkeys allowed within
+    ConsensusParams.Validator.PubKeyTypes
+
+* P2P Protocol
+  - [consensus] [\#2871](https://github.com/tendermint/tendermint/issues/2871)
+    Remove *ProposalHeartbeat* message as it serves no real purpose (@srmo)
+  - [state] Fixes for proposer selection:
+    - [\#2785](https://github.com/tendermint/tendermint/issues/2785) Accum for new validators is `-1.125*totalVotingPower` instead of 0
+    - [\#2941](https://github.com/tendermint/tendermint/issues/2941) val.Accum is preserved during ValidatorSet.Update to avoid being
+      reset to 0
+
+### IMPROVEMENTS:
+
+- [state] [\#2929](https://github.com/tendermint/tendermint/issues/2929) Minor refactor of updateState logic (@danil-lashin)
+- [node] [\#2959](https://github.com/tendermint/tendermint/issues/2959) Allow node to start even if software's BlockProtocol is
+  different from state's BlockProtocol
+- [pex] [\#2959](https://github.com/tendermint/tendermint/issues/2959) Pex reactor logger uses `module=pex`
+
+### BUG FIXES:
+
+- [p2p] [\#2968](https://github.com/tendermint/tendermint/issues/2968) Panic on transport error rather than continuing to run but not
+  accept new connections
+- [p2p] [\#2969](https://github.com/tendermint/tendermint/issues/2969) Fix mismatch in peer count between `/net_info` and the prometheus
+  metrics
+- [rpc] [\#2408](https://github.com/tendermint/tendermint/issues/2408) `/broadcast_tx_commit`: Fix "interface conversion: interface {} in nil, not EventDataTx" panic (could happen if somebody sent a tx using `/broadcast_tx_commit` while Tendermint was being stopped)
+- [state] [\#2785](https://github.com/tendermint/tendermint/issues/2785) Fix accum for new validators to be `-1.125*totalVotingPower`
+  instead of 0, forcing them to wait before becoming the proposer. Also:
+    - do not batch clip
+    - keep accums averaged near 0
+- [txindex/kv] [\#2925](https://github.com/tendermint/tendermint/issues/2925) Don't return false positives when range searching for a prefix of a tag value
+- [types] [\#2938](https://github.com/tendermint/tendermint/issues/2938) Fix regression in v0.26.4 where we panic on empty
+  genDoc.Validators
+- [types] [\#2941](https://github.com/tendermint/tendermint/issues/2941) Preserve val.Accum during ValidatorSet.Update to avoid it being
+  reset to 0 every time a validator is updated

+
+- [config] [\#2877](https://github.com/tendermint/tendermint/issues/2877) Add `blocktime_iota` to the config.toml (@ackratos)

+
+### BREAKING CHANGES:
+
+* Go API
+  - [rpc] [\#2791](https://github.com/tendermint/tendermint/issues/2791) Functions that start HTTP servers are now blocking:

+
+### FEATURES:
+

+
+## v0.26.0
+
+*November 2, 2018*
+
+Special thanks to external contributors on this release:
+@bradyjoestar, @connorwstein, @goolAdapter, @HaoyangLiu,
+@james-ray, @overbool, @phymbert, @Slamper, @Uzair1995, @yutianwu.
+
+Special thanks to @Slamper for a series of bug reports in our [bug bounty
+program](https://hackerone.com/tendermint) which are fixed in this release.
+
+This release is primarily about adding Version fields to various data structures,
+optimizing consensus messages for signing and verification in
+restricted environments (like HSMs and the Ethereum Virtual Machine), and
+aligning the consensus code with the [specification](https://arxiv.org/abs/1807.04938).
+It also includes our first take at a generalized merkle proof system, and
+changes the length of hashes used for hashing data structures from 20 to 32
+bytes.
+
+See the [UPGRADING.md](UPGRADING.md#v0.26.0) for details on upgrading to the new
+version.
+
+Please note that we are still making breaking changes to the protocols.
+While the new Version fields should help us to keep the software backwards compatible
+even while upgrading the protocols, we cannot guarantee that new releases will
+be compatible with old chains just yet. We expect there will be another breaking
+release or two before the Cosmos Hub launch, but we will otherwise be paying
+increasing attention to backwards compatibility. Thanks for bearing with us!
+
+### BREAKING CHANGES:
+
+* CLI/RPC/Config
+  * [config] [\#2232](https://github.com/tendermint/tendermint/issues/2232) Timeouts are now strings like "3s" and "100ms", not ints
+  * [config] [\#2505](https://github.com/tendermint/tendermint/issues/2505) Remove Mempool.RecheckEmpty (it was effectively useless anyways)
+  * [config] [\#2490](https://github.com/tendermint/tendermint/issues/2490) `mempool.wal` is disabled by default
+  * [privval] [\#2459](https://github.com/tendermint/tendermint/issues/2459) Split `SocketPVMsg`s implementations into Request and Response, where the Response may contain a error message (returned by the remote signer)
+  * [state] [\#2644](https://github.com/tendermint/tendermint/issues/2644) Add Version field to State, breaking the format of State as
+    encoded on disk.
+  * [rpc] [\#2298](https://github.com/tendermint/tendermint/issues/2298) `/abci_query` takes `prove` argument instead of `trusted` and switches the default
+    behaviour to `prove=false`
+  * [rpc] [\#2654](https://github.com/tendermint/tendermint/issues/2654) Remove all `node_info.other.*_version` fields in `/status` and
+    `/net_info`

 Special thanks to external contributors on this release:
-@bradyjoestar, @connorwstein, @goolAdapter, @HaoyangLiu,
-@james-ray, @overbool, @phymbert, @Slamper, @Uzair1995
 
-This release is primarily about adding Version fields to various data structures,
-optimizing consensus messages for signing and verification in
-restricted environments (like HSMs and the Ethereum Virtual Machine), and
-aligning the consensus code with the [specification](https://arxiv.org/abs/1807.04938).
-It also includes our first take at a generalized merkle proof system.
-
-See the [UPGRADING.md](UPGRADING.md#v0.26.0) for details on upgrading to the new
-version.
-
-Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint).

+## Changelog
 
-All repos should be hooked up to [CircleCI](https://circleci.com/).
+Every fix, improvement, feature, or breaking change should be made in a
+pull-request that includes an update to the `CHANGELOG_PENDING.md` file.
 
-If they have `.go` files in the root directory, they will be automatically
-tested by circle using `go test -v -race ./...`. If not, they will need a
-`circle.yml`. Ideally, every repo has a `Makefile` that defines `make test` and
-includes its continuous integration status using a badge in the `README.md`.
+Changelog entries should be formatted as follows:
+
+```
+- [module] \#xxx Some description about the change (@contributor)
+```
+
+Here, `module` is the part of the code that changed (typically a
+top-level Go package), `xxx` is the pull-request number, and `contributor`
+is the author/s of the change.
+
+It's also acceptable for `xxx` to refer to the relevent issue number, but pull-request
+numbers are preferred.
+Note this means pull-requests should be opened first so the changelog can then
+be updated with the pull-request's number.
+There is no need to include the full link, as this will be added
+automatically during release. But please include the backslash and pound, eg. `\#2313`.
+
+Changelog entries should be ordered alphabetically according to the
+`module`, and numerically according to the pull-request number.
+
+Changes with multiple classifications should be doubly included (eg. a bug fix
+that is also a breaking change should be recorded under both).
+
+Breaking changes are further subdivided according to the APIs/users they impact.
+Any change that effects multiple APIs/users should be recorded multiply - for
+instance, a change to the `Blockchain Protocol` that removes a field from the
+header should also be recorded under `CLI/RPC/Config` since the field will be
+removed from the header in rpc responses as well.
 
 ## Branching Model and Release
 
-User-facing repos should adhere to the branching model: http://nvie.com/posts/a-successful-git-branching-model/.
-That is, these repos should be well versioned, and any merge to master requires a version bump and tagged release.
-
-Libraries need not follow the model strictly, but would be wise to,
-especially `go-p2p` and `go-rpc`, as their versions are referenced in tendermint core.
+All repos should adhere to the branching model: http://nvie.com/posts/a-successful-git-branching-model/.
+This means that all pull-requests should be made against develop. Any merge to
+master constitutes a tagged release.

 This guide provides steps to be followed when you upgrade your applications to
 a newer version of Tendermint Core.
 
+## v0.28.0
+
+This release breaks the format for the `priv_validator.json` file
+and the protocol used for the external validator process.
+It is compatible with v0.27.0 blockchains (neither the BlockProtocol nor the
+P2PProtocol have changed).
+
+Please read carefully for details about upgrading.
+
+**Note:** Backup your `config/priv_validator.json`
+before proceeding.
+
+### `priv_validator.json`
+
+The `config/priv_validator.json` is now two files:
+`config/priv_validator_key.json` and `data/priv_validator_state.json`.
+The former contains the key material, the later contains the details on the last
+message signed.
+
+When running v0.28.0 for the first time, it will back up any pre-existing
+`priv_validator.json` file and proceed to split it into the two new files.
+Upgrading should happen automatically without problem.
+
+To upgrade manually, use the provided `privValUpgrade.go` script, with exact paths for the old
+`priv_validator.json` and the locations for the two new files. It's recomended
+to use the default paths, of `config/priv_validator_key.json` and
+`data/priv_validator_state.json`, respectively:
+
+```
+go run scripts/privValUpgrade.go <old-path> <new-key-path> <new-state-path>
+```
+
+### External validator signers
+
+The Unix and TCP implementations of the remote signing validator
+have been consolidated into a single implementation.
+Thus in both cases, the external process is expected to dial
+Tendermint. This is different from how Unix sockets used to work, where
+Tendermint dialed the external process.
+
+The `PubKeyMsg` was also split into separate `Request` and `Response` types
+for consistency with other messages.
+
+Note that the TCP sockets don't yet use a persistent key,
+so while they're encrypted, they can't yet be properly authenticated.
+See [#3105](https://github.com/tendermint/tendermint/issues/3105).
+Note the Unix socket has neither encryption nor authentication, but will
+add a shared-secret in [#3099](https://github.com/tendermint/tendermint/issues/3099).
+
+## v0.27.0
+
+This release contains some breaking changes to the block and p2p protocols,
+but does not change any core data structures, so it should be compatible with
+existing blockchains from the v0.26 series that only used Ed25519 validator keys.
+Blockchains using Secp256k1 for validators will not be compatible. This is due
+to the fact that we now enforce which key types validators can use as a
+consensus param. The default is Ed25519, and Secp256k1 must be activated
+explicitly.
+
+It is recommended to upgrade all nodes at once to avoid incompatibilities at the
+peer layer - namely, the heartbeat consensus message has been removed (only
+relevant if `create_empty_blocks=false` or `create_empty_blocks_interval > 0`),
+and the proposer selection algorithm has changed. Since proposer information is
+never included in the blockchain, this change only affects the peer layer.
+
+### Go API Changes
+
+#### libs/db
+
+The ReverseIterator API has changed the meaning of `start` and `end`.
+Before, iteration was from `start` to `end`, where
+`start > end`. Now, iteration is from `end` to `start`, where `start < end`.
+The iterator also excludes `end`. This change allows a simplified and more
+intuitive logic, aligning the semantic meaning of `start` and `end` in the
+`Iterator` and `ReverseIterator`.
+
+### Applications
+
+This release enforces a new consensus parameter, the
+ValidatorParams.PubKeyTypes. Applications must ensure that they only return
+validator updates with the allowed PubKeyTypes. If a validator update includes a
+pubkey type that is not included in the ConsensusParams.Validator.PubKeyTypes,
+block execution will fail and the consensus will halt.
+
+By default, only Ed25519 pubkeys may be used for validators. Enabling
+Secp256k1 requires explicit modification of the ConsensusParams.
+Please update your application accordingly (ie. restrict validators to only be
+able to use Ed25519 keys, or explicitly add additional key types to the genesis
+file).

-## Install ABCI-CLI
-
-The `abci-cli` is a simple tool for debugging ABCI servers and running some
-example apps. To install it:
-
-```
-mkdir -p $GOPATH/src/github.com/tendermint
-cd $GOPATH/src/github.com/tendermint
-git clone https://github.com/tendermint/tendermint.git
-cd tendermint
-make get_tools
-make get_vendor_deps
-make install_abci
-```
-
-## Implementation
-
-We provide three implementations of the ABCI in Go:
-
-- Golang in-process
-- ABCI-socket
-- GRPC
-
-Note the GRPC version is maintained primarily to simplify onboarding and prototyping and is not receiving the same
-attention to security and performance as the others
-
-### In Process
-
-The simplest implementation just uses function calls within Go.
-This means ABCI applications written in Golang can be compiled with TendermintCore and run as a single binary.
-
-See the [examples](#examples) below for more information.
-
-### Socket (TSP)
-
-ABCI is best implemented as a streaming protocol.
-The socket implementation provides for asynchronous, ordered message passing over unix or tcp.
-Messages are serialized using Protobuf3 and length-prefixed with a [signed Varint](https://developers.google.com/protocol-buffers/docs/encoding?csw=1#signed-integers)
-
-For example, if the Protobuf3 encoded ABCI message is `0xDEADBEEF` (4 bytes), the length-prefixed message is `0x08DEADBEEF`, since `0x08` is the signed varint
-encoding of `4`. If the Protobuf3 encoded ABCI message is 65535 bytes long, the length-prefixed message would be like `0xFEFF07...`.
-
-Note the benefit of using this `varint` encoding over the old version (where integers were encoded as `<len of len><big endian len>` is that
-it is the standard way to encode integers in Protobuf. It is also generally shorter.
-
-### GRPC
-
-GRPC is an rpc framework native to Protocol Buffers with support in many languages.
-Implementing the ABCI using GRPC can allow for faster prototyping, but is expected to be much slower than
-the ordered, asynchronous socket protocol. The implementation has also not received as much testing or review.
-
-Note the length-prefixing used in the socket implementation does not apply for GRPC.
-
-## Usage
-
-The `abci-cli` tool wraps an ABCI client and can be used for probing/testing an ABCI server.
-For instance, `abci-cli test` will run a test sequence against a listening server running the Counter application (see below).
-It can also be used to run some example applications.
-See [the documentation](https://tendermint.com/docs/) for more details.
-
-### Examples
-
-Check out the variety of example applications in the [example directory](example/).
-It also contains the code refered to by the `counter` and `kvstore` apps; these apps come
-built into the `abci-cli` binary.
-
-#### Counter
-
-The `abci-cli counter` application illustrates nonce checking in transactions. It's code looks like:
-
-```golang
-func cmdCounter(cmd *cobra.Command, args []string) error {
-
-	app := counter.NewCounterApplication(flagSerial)
-
-	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
-
-	// Start the listener
-	srv, err := server.NewServer(flagAddrC, flagAbci, app)
-	if err != nil {
-		return err
-	}
-	srv.SetLogger(logger.With("module", "abci-server"))
-	if err := srv.Start(); err != nil {
-		return err
-	}
-
-	// Wait forever
-	cmn.TrapSignal(func() {
-		// Cleanup
-		srv.Stop()
-	})
-	return nil
-}
-```
-
-and can be found in [this file](cmd/abci-cli/abci-cli.go).
-
-#### kvstore
-
-The `abci-cli kvstore` application, which illustrates a simple key-value Merkle tree
-
-```golang
-func cmdKVStore(cmd *cobra.Command, args []string) error {
-	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
-
-	// Create the application - in memory or persisted to disk
-	var app types.Application
-	if flagPersist == "" {
-		app = kvstore.NewKVStoreApplication()
-	} else {
-		app = kvstore.NewPersistentKVStoreApplication(flagPersist)
-		app.(*kvstore.PersistentKVStoreApplication).SetLogger(logger.With("module", "kvstore"))
-	}
-
-	// Start the listener
-	srv, err := server.NewServer(flagAddrD, flagAbci, app)
-	if err != nil {

 open ABCI connection with the application, which hosts an ABCI server.
 Shown are the request and response types sent on each connection.
 
-## Message Protocol
-
-The message protocol consists of pairs of requests and responses. Some
-messages have no fields, while others may include byte-arrays, strings,
-or integers. See the `message Request` and `message Response`
-definitions in [the protobuf definition
-file](https://github.com/tendermint/tendermint/blob/develop/abci/types/types.proto),
-and the [protobuf
-documentation](https://developers.google.com/protocol-buffers/docs/overview)
-for more details.
-
-For each request, a server should respond with the corresponding
-response, where order of requests is preserved in the order of
-responses.
-
-## Server
-
-To use ABCI in your programming language of choice, there must be a ABCI
-server in that language. Tendermint supports two kinds of implementation
-of the server:
-
-- Asynchronous, raw socket server (Tendermint Socket Protocol, also
-  known as TSP or Teaspoon)
-- GRPC
-
-Both can be tested using the `abci-cli` by setting the `--abci` flag
-appropriately (ie. to `socket` or `grpc`).
-
-See examples, in various stages of maintenance, in
-[Go](https://github.com/tendermint/tendermint/tree/develop/abci/server),
-[JavaScript](https://github.com/tendermint/js-abci),
-[Python](https://github.com/tendermint/tendermint/tree/develop/abci/example/python3/abci),
-[C++](https://github.com/mdyring/cpp-tmsp), and
-[Java](https://github.com/jTendermint/jabci).
-
-### GRPC
-
-If GRPC is available in your language, this is the easiest approach,
-though it will have significant performance overhead.
-
-To get started with GRPC, copy in the [protobuf
-file](https://github.com/tendermint/tendermint/blob/develop/abci/types/types.proto)
-and compile it using the GRPC plugin for your language. For instance,
-for golang, the command is `protoc --go_out=plugins=grpc:. types.proto`.
-See the [grpc documentation for more details](http://www.grpc.io/docs/).
-`protoc` will autogenerate all the necessary code for ABCI client and
-server in your language, including whatever interface your application
-must satisfy to be used by the ABCI server for handling requests.
-
-### TSP
-
-If GRPC is not available in your language, or you require higher
-performance, or otherwise enjoy programming, you may implement your own
-ABCI server using the Tendermint Socket Protocol, known affectionately
-as Teaspoon. The first step is still to auto-generate the relevant data
-types and codec in your language using `protoc`. Messages coming over
-the socket are proto3 encoded, but additionally length-prefixed to
-facilitate use as a streaming protocol. proto3 doesn't have an
-official length-prefix standard, so we use our own. The first byte in
-the prefix represents the length of the Big Endian encoded length. The
-remaining bytes in the prefix are the Big Endian encoded length.
-
-For example, if the proto3 encoded ABCI message is 0xDEADBEEF (4
-bytes), the length-prefixed message is 0x0104DEADBEEF. If the proto3
-encoded ABCI message is 65535 bytes long, the length-prefixed message
-would be like 0x02FFFF....
-
-Note this prefixing does not apply for grpc.
-
-An ABCI server must also be able to support multiple connections, as
-Tendermint uses three connections.
-
-## Client
-
-There are currently two use-cases for an ABCI client. One is a testing
-tool, as in the `abci-cli`, which allows ABCI requests to be sent via
-command line. The other is a consensus engine, such as Tendermint Core,
-which makes requests to the application every time a new transaction is
-received or a block is committed.
-
-It is unlikely that you will need to implement a client. For details of
-our client, see
-[here](https://github.com/tendermint/tendermint/tree/develop/abci/client).

 for that in most cases you'll need to add `instance` field to a logger upon creating, not when u log a particular message:

+# ADR 033: pubsub 2.0
+
+Author: Anton Kaliaev (@melekes)
+
+## Changelog
+
+02-10-2018: Initial draft
+
+## Context
+
+Since the initial version of the pubsub, there's been a number of issues
+raised: #951, #1879, #1880. Some of them are high-level issues questioning the
+core design choices made. Others are minor and mostly about the interface of
+`Subscribe()` / `Publish()` functions.
+
+### Sync vs Async
+
+Now, when publishing a message to subscribers, we can do it in a goroutine:
+
+_using channels for data transmission_
+```go
+for each subscriber {
+    out := subscriber.outc
+    go func() {
+        out <- msg
+    }
+}
+```
+
+_by invoking callback functions_
+```go
+for each subscriber {
+    go subscriber.callbackFn()
+}
+```
+
+This gives us greater performance and allows us to avoid "slow client problem"
+(when other subscribers have to wait for a slow subscriber). A pool of
+goroutines can be used to avoid uncontrolled memory growth.
+
+In certain cases, this is what you want. But in our case, because we need
+strict ordering of events (if event A was published before B, the guaranteed
+delivery order will be A -> B), we can't use goroutines.
+
+There is also a question whenever we should have a non-blocking send:
+
+```go
+for each subscriber {
+    out := subscriber.outc
+    select {
+        case out <- msg:
+        default:
+            log("subscriber %v buffer is full, skipping...")
+    }
+}
+```
+
+This fixes the "slow client problem", but there is no way for a slow client to
+know if it had missed a message. On the other hand, if we're going to stick
+with blocking send, **devs must always ensure subscriber's handling code does not
+block**. As you can see, there is an implicit choice between ordering guarantees
+and using goroutines.
+
+The interim option is to run goroutines pool for a single message, wait for all
+goroutines to finish. This will solve "slow client problem", but we'd still
+have to wait `max(goroutine_X_time)` before we can publish the next message.
+My opinion: not worth doing.
+
+### Channels vs Callbacks
+
+Yet another question is whether we should use channels for message transmission or
+call subscriber-defined callback functions. Callback functions give subscribers
+more flexibility - you can use mutexes in there, channels, spawn goroutines,
+anything you really want. But they also carry local scope, which can result in
+memory leaks and/or memory usage increase.
+
+Go channels are de-facto standard for carrying data between goroutines.
+
+**Question: Is it worth switching to callback functions?**
+
+### Why `Subscribe()` accepts an `out` channel?
+
+Because in our tests, we create buffered channels (cap: 1). Alternatively, we
+can make capacity an argument.
+
+## Decision
+
+Change Subscribe() function to return out channel:
+
+```go
+// outCap can be used to set capacity of out channel (unbuffered by default).
+Subscribe(ctx context.Context, clientID string, query Query, outCap... int) (out <-chan interface{}, err error) {
+```
+
+It's more idiomatic since we're closing it during Unsubscribe/UnsubscribeAll calls.
+
+Also, we should make tags available to subscribers:
+
+```go
+type MsgAndTags struct {
+    Msg interface{}
+    Tags TagMap
+}
+
+// outCap can be used to set capacity of out channel (unbuffered by default).
+Subscribe(ctx context.Context, clientID string, query Query, outCap... int) (out <-chan MsgAndTags, err error) {
+```
+
+## Status
+
+In review
+
+## Consequences
+
+### Positive
+
+- more idiomatic interface
+- subscribers know what tags msg was published with
+
+### Negative
+
+### Neutral

+# ADR 034: PrivValidator file structure
+
+## Changelog
+
+03-11-2018: Initial Draft
+
+## Context
+
+For now, the PrivValidator file `priv_validator.json` contains mutable and immutable parts. 
+Even in an insecure mode which does not encrypt private key on disk, it is reasonable to separate 
+the mutable part and immutable part.
+
+References:
+[#1181](https://github.com/tendermint/tendermint/issues/1181)
+[#2657](https://github.com/tendermint/tendermint/issues/2657)
+[#2313](https://github.com/tendermint/tendermint/issues/2313)
+
+## Proposed Solution
+
+We can split mutable and immutable parts with two structs:
+```go
+// FilePVKey stores the immutable part of PrivValidator
+type FilePVKey struct {
+	Address types.Address  `json:"address"`
+	PubKey  crypto.PubKey  `json:"pub_key"`
+	PrivKey crypto.PrivKey `json:"priv_key"`
+
+	filePath string
+}
+
+// FilePVState stores the mutable part of PrivValidator
+type FilePVLastSignState struct {
+	Height    int64        `json:"height"`
+	Round     int          `json:"round"`
+	Step      int8         `json:"step"`
+	Signature []byte       `json:"signature,omitempty"`
+	SignBytes cmn.HexBytes `json:"signbytes,omitempty"`
+
+	filePath string
+	mtx      sync.Mutex
+}
+```
+
+Then we can combine `FilePVKey` with `FilePVLastSignState` and will get the original `FilePV`.
+
+```go
+type FilePV struct {
+	Key           FilePVKey
+	LastSignState FilePVLastSignState
+}
+```
+
+As discussed, `FilePV` should be located in `config`, and `FilePVLastSignState` should be stored in `data`. The 
+store path of each file should be specified in `config.yml`.
+
+What we need to do next is changing the methods of `FilePV`.
+
+## Status
+
+Draft.

+# ADR 035: Documentation
+
+Author: @zramsay (Zach Ramsay)
+
+## Changelog
+
+###  November 2nd 2018
+
+- initial write-up
+
+## Context
+
+The Tendermint documentation has undergone several changes until settling on the current model. Originally, the documentation was hosted on the website and had to be updated asynchronously from the code. Along with the other repositories requiring documentation, the whole stack moved to using Read The Docs to automatically generate, publish, and host the documentation. This, however, was insufficient; the RTD site had advertisement, it wasn't easily accessible to devs, didn't collect metrics, was another set of external links, etc.
+
+## Decision
+
+For two reasons, the decision was made to use VuePress:
+
+1) ability to get metrics (implemented on both Tendermint and SDK)
+2) host the documentation on the website as a `/docs` endpoint.
+
+This is done while maintaining synchrony between the docs and code, i.e., the website is built whenever the docs are updated.
+
+## Status
+
+The two points above have been implemented; the `config.js` has a Google Analytics identifier and the documentation workflow has been up and running largely without problems for several months. Details about the documentation build & workflow can be found [here](../DOCS_README.md)
+
+## Consequences
+
+Because of the organizational seperation between Tendermint & Cosmos, there is a challenge of "what goes where" for certain aspects of documentation.
+
+### Positive
+
+This architecture is largely positive relative to prior docs arrangements.
+
+### Negative
+
+A significant portion of the docs automation / build process is in private repos with limited access/visibility to devs. However, these tasks are handled by the SRE team.
+
+### Neutral

 ## Context
 
+> This section contains all the context one needs to understand the current state, and why there is a problem. It should be as succinct as possible and introduce the high level idea behind the solution. 
 ## Decision
 
+> This section explains all of the details of the proposed solution, including implementation details.
+It should also describe affects / corollary items that may need to be changed as a part of this.
+If the proposed change will be large, please also indicate a way to do the change to maximize ease of review.
+(e.g. the optimal split of things to do between separate PR's)
+
 ## Status
 
+> A decision may be "proposed" if it hasn't been agreed upon yet, or "accepted" once it is agreed upon. If a later ADR changes or reverses a decision, it may be marked as "deprecated" or "superseded" with a reference to its replacement.
