-- [rpc] \#6329 Don't cap page size in unsafe mode (@gotjoshua, @cmwaters)
-- [pex] \#6305 v2 pex reactor with backwards compatability. Introduces two new pex messages to
-  accomodate for the new p2p stack. Removes the notion of seeds and crawling. All peer
-  exchange reactors behave the same. (@cmwaters)
-- [crypto] \#6376 Enable sr25519 as a validator key type
-- [mempool] \#6466 Introduction of a prioritized mempool. (@alexanderbez)
-  - `Priority` and `Sender` have been introduced into the `ResponseCheckTx` type, where the `priority` will determine the prioritization of
-  the transaction when a proposer reaps transactions for a block proposal. The `sender` field acts as an index.
-  - Operators may toggle between the legacy mempool reactor, `v0`, and the new prioritized reactor, `v1`, by setting the
-  `mempool.version` configuration, where `v1` is the default configuration.
-  - Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
-  - Transactions are gossiped in FIFO order as they are in `v0`.

-- [blocksync/v2] \#5774 Send status request when new peer joins (@melekes)
-- [store] \#5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
-- [consensus] \#5987 and \#5792 Remove the `time_iota_ms` consensus parameter. Merge `tmproto.ConsensusParams` and `abci.ConsensusParams`. (@marbar3778, @valardragon)
-- [types] \#5994 Reduce the use of protobuf types in core logic. (@marbar3778)
-  - `ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams`, `sm.Version` and `version.Consensus` have become native types. They still utilize protobuf when being sent over the wire or written to disk.
-- [rpc/client/http] \#6163 Do not drop events even if the `out` channel is full (@melekes)
-- [node] \#6059 Validate and complete genesis doc before saving to state store (@silasdavis)

-- [crypto] \#6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778)
-- [types] \#6120 use batch verification for verifying commits signatures.
-  - If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.

+  - `Priority` and `Sender` have been introduced into the `ResponseCheckTx` type, where the `priority` will determine the prioritization of
+  the transaction when a proposer reaps transactions for a block proposal. The `sender` field acts as an index.
+  - Operators may toggle between the legacy mempool reactor, `v0`, and the new prioritized reactor, `v1`, by setting the
+  `mempool.version` configuration, where `v1` is the default configuration.
+  - Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
+  - Transactions are gossiped in FIFO order as they are in `v0`.

+- [blockchain/v2] \#5774 Send status request when new peer joins (@melekes)
+- [consensus] \#5792 Deprecates the `time_iota_ms` consensus parameter, to reduce the bug surface. The parameter is no longer used. (@valardragon)
+- [store] \#5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
+- [consensus] \#5987 Remove `time_iota_ms` from consensus params. Merge `tmproto.ConsensusParams` and `abci.ConsensusParams`. (@marbar3778)
+- [types] \#5994 Reduce the use of protobuf types in core logic. (@marbar3778)
+  - `ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams`, `sm.Version` and `version.Consensus` have become native types. They still utilize protobuf when being sent over the wire or written to disk.

+- [state] \#6067 Batch save state data (@githubsands & @cmwaters)
+- [crypto] \#6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778)
+- [types] \#6120 use batch verification for verifying commits signatures.
+  - If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.
+- [privval/file] \#6185 Return error on `LoadFilePV`, `LoadFilePVEmptyState`. Allows for better programmatic control of Tendermint.
+- [privval] \#6240 Add `context.Context` to privval interface.
+- [rpc] \#6265 set cache control in http-rpc response header (@JayT106)
+- [statesync] \#6378 Retry requests for snapshots and add a minimum discovery time (5s) for new snapshots.
+- [node/state] \#6370 graceful shutdown in the consensus reactor (@JayT106)

 Each PR should have one commit once it lands on `master`; this can be accomplished by using the "squash and merge" button on Github. Be sure to edit your commit message, though!
 
-### Release procedure
+### Release Procedure
 
-#### A note about backport branches
-Tendermint's `master` branch is under active development.
-Releases are specified using tags and are built from long-lived "backport" branches.
-Each release "line" (e.g. 0.34 or 0.33) has its own long-lived backport branch,
-and the backport branches have names like `v0.34.x` or `v0.33.x`
-(literally, `x`; it is not a placeholder in this case).
-
-As non-breaking changes land on `master`, they should also be backported (cherry-picked)
-to these backport branches.
-
-We use Mergify's [backport feature](https://mergify.io/features/backports) to automatically backport
-to the needed branch. There should be a label for any backport branch that you'll be targeting.
-To notify the bot to backport a pull request, mark the pull request with
-the label `S:backport-to-<backport_branch>`.
-Once the original pull request is merged, the bot will try to cherry-pick the pull request
-to the backport branch. If the bot fails to backport, it will open a pull request.
-The author of the original pull request is responsible for solving the conflicts and
-merging the pull request.
-
-#### Creating a backport branch
-If this is the first release candidate for a major release, you get to have the honor of creating
-the backport branch!
-
-Note that, after creating the backport branch, you'll also need to update the tags on `master`
-so that `go mod` is able to order the branches correctly. You should tag `master` with a "dev" tag
-that is "greater than" the backport branches tags. See #6072 for more context.
-
-In the following example, we'll assume that we're making a backport branch for
-the 0.35.x line.
-
-1. Start on `master`
-2. Create the backport branch:
-   `git checkout -b v0.35.x`
-3. Go back to master and tag it as the dev branch for the _next_ major release and push it back up:
-   `git tag -a v0.36.0-dev; git push v0.36.0-dev`
-4. Create a new workflow to run the e2e nightlies for this backport branch.
-   (See https://github.com/tendermint/tendermint/blob/master/.github/workflows/e2e-nightly-34x.yml
-   for an example.)
-
-#### Release candidates
-
-Before creating an official release, especially a major release, we may want to create a
-release candidate (RC) for our friends and partners to test out. We use git tags to
-create RCs, and we build them off of backport branches.
-

+
+#### Minor Release (Point Releases)
 
 Minor releases are done differently from major releases: They are built off of long-lived backport branches, rather than from master.
+Each release "line" (e.g. 0.34 or 0.33) has its own long-lived backport branch, and
+the backport branches have names like `v0.34.x` or `v0.33.x` (literally, `x`; it is not a placeholder in this case).
+
 As non-breaking changes land on `master`, they should also be backported (cherry-picked) to these backport branches.
 
+We use Mergify's [backport feature](https://mergify.io/features/backports) to automatically backport to the needed branch. Depending on which backport branch you need to backport to there will be labels for them. To notify the bot to backport a pull request, mark the pull request with the label `backport-to-<backport_branch>`. Once the original pull request is merged, the bot will try to cherry-pick the pull request to the backport branch. If the bot fails to backport, it will open a pull request. The author of the original pull request is responsible for solving the conflicts and merging the pull request.
+
 Minor releases don't have release candidates by default, although any tricky changes may merit a release candidate.

-1. Checkout the long-lived backport branch: `git checkout v0.35.x`

+#### Release Candidates
+
+Before creating an official release, especially a major release, we may want to create a
+release candidate (RC) for our friends and partners to test out. We use git tags to
+create RCs, and we build them off of RC branches. RC branches typically have names formatted
+like `RCX/vX.X.X` (or, concretely, `RC0/v0.34.0`), while the tags themselves follow
+the "standard" release naming conventions, with `-rcX` at the end (`vX.X.X-rcX`).
+
+(Note that branches and tags _cannot_ have the same names, so it's important that these branches
+have distinct names from the tags/release names.)
+
+1. Start from the RC branch (e.g. `RC0/v0.34.0`).
+2. Create the new tag, specifying a name and a tag "message":
+   `git tag -a v0.34.0-rc0 -m "Release Candidate v0.34.0-rc0`
+3. Push the tag back up to origin:
+   `git push origin v0.34.0-rc4`
+   Now the tag should be available on the repo's releases page.
+4. Create a new release candidate branch for any possible updates to the RC:
+   `git checkout -b RC1/v0.34.0; git push origin RC1/v0.34.0`

-### API Changes
-
-The p2p layer was reimplemented as part of the 0.35 release cycle and
-all reactors were refactored to accomodate the change. As part of that work these
-implementations moved into the `internal` package and are no longer
-considered part of the public Go API of tendermint. These packages
-are:
-
-- `p2p`
-- `mempool`
-- `consensus`
-- `statesync`
-- `blockchain`
-- `evidence`
-
-Accordingly, the `node` package was changed to reduce access to
-tendermint internals: applications that use tendermint as a library
-will need to change to accommodate these changes. Most notably:
-
-- The `Node` type has become internal, and all constructors return a
-  `service.Service` implementation.
-
-- The `node.DefaultNewNode` and `node.NewNode` constructors are no
-  longer exported and have been replaced with `node.New` and
-  `node.NewDefault` which provide more functional interfaces.
-
-### gRPC Support
-
-Mark gRPC in the RPC layer as deprecated and to be removed in 0.36.
-
-### Peer Management Interface
-
-When running with the new P2P Layer, the methods `UnsafeDialSeeds` and
-`UnsafeDialPeers` RPC methods will always return an error. They are
-deprecated and will be removed in 0.36 when the legacy peer stack is
-removed.
-
-Additionally the format of the Peer list returned in the `NetInfo`
-method changes in this release to accommodate the different way that
-the new stack tracks data about peers. This change affects users of
-both stacks.
-
-### Using the updated p2p library
-
-The P2P library was reimplemented in this release. The new implementation is
-enabled by default in this version of Tendermint. The legacy implementation is still
-included in this version of Tendermint as a backstop to work around unforeseen
-production issues. The new and legacy version are interoperable. If necessary, 
-you can enable the legacy implementation in the server configuration file.
-
-To make use of the legacy P2P implemementation add or update the following field of 
-your server's configuration file under the `[p2p]` section:
-
-```toml
-[p2p]
-...
-use-legacy = true
-...
-```
-
-If you need to do this, please consider filing an issue in the Tendermint repository
-to let us know why. We plan to remove the legacy P2P code in the next (v0.36) release.
-
-#### New p2p queue types
-
-The new p2p implementation enables selection of the queue type to be used for
-passing messages between peers.
-
-The following values may be used when selecting which queue type to use:
-
-* `fifo`: (**default**) An unbuffered and lossless queue that passes messages through
-in the order in which they were received.
-
-* `priority`: A priority queue of messages.
-
-* `wdrr`: A queue implementing the Weighted Deficit Round Robin algorithm. A 
-weighted deficit round robin queue is created per peer. Each queue contains a 
-separate 'flow' for each of the channels of communication that exist between any two
-peers. Tendermint maintains a channel per message type between peers. Each WDRR
-queue maintains a shared buffered with a fixed capacity through which messages on different
-flows are passed.
-For more information on WDRR scheduling, see: https://en.wikipedia.org/wiki/Deficit_round_robin
-
-To select a queue type, add or update the following field under the `[p2p]`
-section of your server's configuration file.
-
-```toml
-[p2p]
-...
-queue-type = wdrr
-...
-```
-
-
-### Support for Custom Reactor and Mempool Implementations
-
-The changes to p2p layer removed existing support for custom
-reactors. Based on our understanding of how this functionality was
-used, the introduction of the prioritized mempool covers nearly all of
-the use cases for custom reactors. If you are currently running custom
-reactors and mempools and are having trouble seeing the migration path
-for your project please feel free to reach out to the Tendermint Core
-development team directly.

+## Counter - Another Example
+
+Now that we've got the hang of it, let's try another application, the
+"counter" app.
+
+Like the kvstore app, its code can be found
+[here](https://github.com/tendermint/tendermint/blob/master/abci/cmd/abci-cli/abci-cli.go)
+and looks like:
+
+```go
+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
+    }
+
+    // Stop upon receiving SIGTERM or CTRL-C.
+    tmos.TrapSignal(logger, func() {
+        // Cleanup
+        srv.Stop()
+    })
+
+    // Run forever.
+    select {}
+}
+```
+
+The counter app doesn't use a Merkle tree, it just counts how many times
+we've sent a transaction, asked for a hash, or committed the state. The
+result of `commit` is just the number of transactions sent.
+
+This application has two modes: `serial=off` and `serial=on`.
+
+When `serial=on`, transactions must be a big-endian encoded incrementing
+integer, starting at 0.
+
+If `serial=off`, there are no restrictions on transactions.
+
+We can toggle the value of `serial` using the `set_option` ABCI message.
+
+When `serial=on`, some transactions are invalid. In a live blockchain,
+transactions collect in memory before they are committed into blocks. To
+avoid wasting resources on invalid transactions, ABCI provides the
+`check_tx` message, which application developers can use to accept or
+reject transactions, before they are stored in memory or gossipped to
+other peers.
+
+In this instance of the counter app, `check_tx` only allows transactions
+whose integer is greater than the last committed one.
+
+Let's kill the console and the kvstore application, and start the
+counter app:
+
+```sh
+abci-cli counter
+```
+
+In another window, start the `abci-cli console`:
+
+```sh
+
+> check_tx 0x00
+-> code: OK
+
+> check_tx 0xff
+-> code: OK
+
+> deliver_tx 0x00
+-> code: OK
+
+> check_tx 0x00
+-> code: BadNonce
+-> log: Invalid nonce. Expected >= 1, got 0
+
+> deliver_tx 0x01
+-> code: OK
+
+> deliver_tx 0x04
+-> code: BadNonce
+-> log: Invalid nonce. Expected 2, got 4
+
+> info
+-> code: OK
+-> data: {"hashes":0,"txs":2}
+-> data.hex: 0x7B22686173686573223A302C22747873223A327D
+```
+
+This is a very simple application, but between `counter` and `kvstore`,
+its easy to see how you can build out arbitrary application states on
+top of the ABCI. [Hyperledger's
+Burrow](https://github.com/hyperledger/burrow) also runs atop ABCI,
+bringing with it Ethereum-like accounts, the Ethereum virtual-machine,
+Monax's permissioning scheme, and native contracts extensions.
+
+But the ultimate flexibility comes from being able to write the
+application easily in any language.
+
+We have implemented the counter in a number of languages [see the
+example directory](https://github.com/tendermint/tendermint/tree/master/abci/example).
+
+To run the Node.js version, fist download & install [the Javascript ABCI server](https://github.com/tendermint/js-abci):
+
+```sh
+git clone https://github.com/tendermint/js-abci.git
+cd js-abci
+npm install abci
+```
+
+Now you can start the app:
+
+```sh
+node example/counter.js
+```
+
+(you'll have to kill the other counter application process). In another
+window, run the console and those previous ABCI commands. You should get
+the same results as for the Go version.

+transactions, ABCI provides the `CheckTx` message, which application
+developers can use to accept or reject transactions, before they are
+stored in memory or gossipped to other peers.
+
+In this instance of the counter app, with `serial=on`, `CheckTx` only
+allows transactions whose integer is greater than the last committed
+one.
+
+Let's kill the previous instance of `tendermint` and the `kvstore`
+application, and start the counter app. We can enable `serial=on` with a
+flag:
+
+```sh
+abci-cli counter --serial
+```
+
+In another window, reset then start Tendermint:
+
+```sh
+tendermint unsafe_reset_all
+tendermint start
+```
+
+Once again, you can see the blocks streaming by. Let's send some
+transactions. Since we have set `serial=on`, the first transaction must
+be the number `0`:
+
+```sh
+curl localhost:26657/broadcast_tx_commit?tx=0x00
+```
+
+Note the empty (hence successful) response. The next transaction must be
+the number `1`. If instead, we try to send a `5`, we get an error:
+
+```json
+> curl localhost:26657/broadcast_tx_commit?tx=0x05
+{
+  "jsonrpc": "2.0",
+  "id": "",
+  "result": {
+    "check_tx": {},
+    "deliver_tx": {
+      "code": 2,
+      "log": "Invalid nonce. Expected 1, got 5"
+    },
+    "hash": "33B93DFF98749B0D6996A70F64071347060DC19C",
+    "height": 34
+  }
+}
+```
+
+But if we send a `1`, it works again:
+
+```json
+> curl localhost:26657/broadcast_tx_commit?tx=0x01
+{
+  "jsonrpc": "2.0",
+  "id": "",
+  "result": {
+    "check_tx": {},
+    "deliver_tx": {},

+    "height": 60
+  }
+}
+```

 would be equal to the composite key of `jack.account.number`.
 
-By default, Tendermint will index all transactions by their respective hashes
-and height and blocks by their height.
-
-## Configuration
-
-Operators can configure indexing via the `[tx_index]` section. The `indexer`
-field takes a series of supported indexers. If `null` is included, indexing will
-be turned off regardless of other values provided.
+Let's take a look at the `[tx_index]` config section:
 
 ```toml
-[tx-index]
+##### transactions indexer configuration options #####
+[tx_index]
 
-# The backend database list to back the indexer.
-# If list contains null, meaning no indexer service will be used.
-#
-# The application will set which txs to index. In some cases a node operator will be able
-# to decide which txs to index based on configuration set in the application.
+# What indexer to use for transactions
 #
 # Options:
 #   1) "null"
 #   2) "kv" (default) - the simplest possible indexer, backed by key-value storage (defaults to levelDB; see DBBackend).
-#     - When "kv" is chosen "tx.height" and "tx.hash" will always be indexed.
-#   3) "psql" - the indexer services backed by PostgreSQL.
-# indexer = []
+indexer = "kv"
 ```
 
-### Supported Indexers
+By default, Tendermint will index all transactions by their respective hashes
+and height and blocks by their height.
 
-#### KV
-
-The `kv` indexer type is an embedded key-value store supported by the main
-underlying Tendermint database. Using the `kv` indexer type allows you to query
-for block and transaction events directly against Tendermint's RPC. However, the
-query syntax is limited and so this indexer type might be deprecated or removed
-entirely in the future.
-
-#### PostgreSQL
-
-The `psql` indexer type allows an operator to enable block and transaction event
-indexing by proxying it to an external PostgreSQL instance allowing for the events
-to be stored in relational models. Since the events are stored in a RDBMS, operators
-can leverage SQL to perform a series of rich and complex queries that are not
-supported by the `kv` indexer type. Since operators can leverage SQL directly,
-searching is not enabled for the `psql` indexer type via Tendermint's RPC -- any
-such query will fail.
-
-Note, the SQL schema is stored in `state/indexer/sink/psql/schema.sql` and operators
-must explicitly create the relations prior to starting Tendermint and enabling
-the `psql` indexer type.
-
-Example:
-
-```shell
-$ psql ... -f state/indexer/sink/psql/schema.sql
-```
+You can turn off indexing completely by setting `tx_index` to `null`.
