# Changelog
## 0.20.0
*June 6th, 2018*
This is the first in a series of breaking releases coming to Tendermint after
soliciting developer feedback and conducting security audits.
This release does not break any blockchain data structures or
protocols other than the ABCI messages between Tendermint and the application.
Applications that upgrade for ABCI v0.11.0 should be able to continue running Tendermint
v0.20.0 on blockchains created with v0.19.X
BREAKING CHANGES
- [abci] Upgrade to
[v0.11.0](https://github.com/tendermint/abci/blob/master/CHANGELOG.md#0110)
- [abci] Change Query path for filtering peers by node ID from
`p2p/filter/pubkey/<id>` to `p2p/filter/id/<id>`
## 0.19.9
*June 5th, 2018*

In what follows, we provide the type names and prefix bytes directly.
Notice that when encoding byte-arrays, the length of the byte-array is appended
to the PrefixBytes. Thus the encoding of a byte array becomes `<PrefixBytes>

familiar with amino encoding.
You can simply use below table and concatenate Prefix || Length (of raw bytes) || raw bytes

### Addresses
Addresses for each public key types are computed as follows:
#### Ed25519
RIPEMD160 hash of the Amino encoded public key:
```
address = RIPEMD160(AMINO(pubkey))
```
NOTE: this will soon change to the truncated 20-bytes of the SHA256 of the raw
public key
#### Secp256k1
RIPEMD160 hash of the SHA256 hash of the OpenSSL compressed public key:
```
address = RIPEMD160(SHA256(pubkey))
```
This is the same as Bitcoin.

The `pub_key` is the Amino encoded public key for the validator. For details on
Amino encoded public keys, see the [section of the encoding spec](https://github.com/tendermint/tendermint/blob/master/docs/spec/blockchain/encoding.md#public-key-cryptography).
The `pub_key` currently supports two types:
- `type = "ed25519" and `data = <raw 32-byte public key>`
- `type = "secp256k1" and `data = <33-byte OpenSSL compressed public key>`
If the address is provided, it must match the address of the pubkey, as
specified [here](/docs/spec/blockchain/encoding.md#Addresses)
(Note: In the v0.19 series, the `pub_key` is the [Amino encoded public
key](/docs/spec/blockchain/encoding.md#public-key-cryptography).
For Ed25519 pubkeys, the Amino prefix is always "1624DE6220". For example, the 32-byte Ed25519 pubkey

## InitChain Validator Updates
ResponseInitChain has the option to return a list of validators.
If the list is not empty, Tendermint will adopt it for the validator set.
This way the application can determine the initial validator set for the
blockchain.
Note that if addressses are included in the returned validators, they must match
the address of the public key.
ResponseInitChain also includes ConsensusParams, but these are presently
