0.6.2 (July 27, 2017)

IMPROVEMENTS:

• auto-test all tutorials to detect breaking changes
• move deployment scripts from /scripts to /publish for clarity

BUG FIXES:

• basecoin init ensures the address in genesis.json is valid
• fix bug that certain addresses couldn't receive ibc packets

0.6.1 (June 28, 2017)

Make lots of small cli fixes that arose when people were using the tools for the testnet.

IMPROVEMENTS:

• basecoin
  • basecoin start supports all flags that tendermint node does, such as --rpc.laddr, --p2p.seeds, and --p2p.skip_upnp
  • fully supports --log_level and --trace for logger configuration
  • merkleeyes no longers spams the logs... unless you want it
    • Example: basecoin start --log_level="merkleeyes:info,state:info,*:error"
    • Example: basecoin start --log_level="merkleeyes:debug,state:info,*:error"
• basecli
  • basecli init is more intelligent and only complains if there really was a connected chain, not just random files
  • support localhost:46657 or http://localhost:46657 format for nodes, not just tcp://localhost:46657
  • Add --genesis to init to specify chain-id and validator hash
    • Example: basecli init --node=localhost:46657 --genesis=$HOME/.basecoin/genesis.json
  • basecli rpc has a number of methods to easily accept tendermint rpc, and verifies what it can

BUG FIXES:

• basecli
  • basecli query account accepts hex account address with or without 0x prefix
  • gives error message when running commands on an unitialized chain, rather than some unintelligable panic

0.6.0 (June 22, 2017)

Make the basecli command the only way to use client-side, to enforce best security practices. Lots of enhancements to get it up to production quality.

BREAKING CHANGES:

• ./cmd/commands -> ./cmd/basecoin/commands
• basecli
  • basecli proof state get -> basecli query key
  • basecli proof tx get -> basecli query tx
  • basecli proof state get --app=account -> basecli query account
  • use --chain-id not --chainid for consistency
  • update to use --trace not --debug for stack traces on errors
  • complete overhaul on how tx and query subcommands are added. (see counter or trackomatron for examples)
  • no longer supports counter app (see new countercli)
• basecoin
  • basecoin init takes an argument, an address to allocate funds to in the genesis
  • removed key2.json
  • removed all client side functionality from it (use basecli now for proofs)
    • no tx subcommand
    • no query subcommand
    • no account (query) subcommand
    • a few other random ones...
  • enhanced relay subcommand
    • relay start did what relay used to do
    • relay init registers both chains on one another (to set it up so relay start just works)
• docs
  • removed example-plugin, put counter inside docs/guide
• app
  • Implements ABCI handshake by proxying merkleeyes.Info()

IMPROVEMENTS:

• basecoin init support --chain-id
• intergrates tendermint 0.10.0 (not the rc-2, but the real thing)
• commands return error code (1) on failure for easier script testing
• add reset_all to basecli, and never delete keys on init
• new shutil based unit tests, with better coverage of the cli actions
• just make fresh when things are getting stale ;)

BUG FIXES:

• app: no longer panics on missing app_options in genesis (thanks, anton)
• docs: updated all docs... again
• ibc: fix panic on getting BlockID from commit without 100% precommits (still a TODO)

0.5.2 (June 2, 2017)

BUG FIXES:

• fix parsing of the log level from Tendermint config (#97)

0.5.1 (May 30, 2017)

BUG FIXES:

• fix ibc demo app to use proper tendermint flags, 0.10.0-rc2 compatibility
• Make sure all cli uses new json.Marshal not wire.JSONBytes

0.5.0 (May 27, 2017)

BREAKING CHANGES:

• only those related to the tendermint 0.9 -> 0.10 upgrade

IMPROVEMENTS:

• basecoin cli
  • integrates tendermint 0.10.0 and unifies cli (init, unsafe_reset_all, ...)
  • integrate viper, all command line flags can also be defined in environmental variables or config.toml
• genesis file
  • you can define accounts with either address or pub_key
  • sorts coins for you, so no silent errors if not in alphabetical order
• light-client integration
  • no longer must you trust the node you connect to, prove everything!
  • new basecli command
  • integrated key management, stored encrypted locally
  • tracks validator set changes and proves everything from one initial validator seed
  • basecli proof state gets complete proofs for any abci state
  • basecli proof tx gets complete proof where a tx was stored in the chain
  • basecli proxy exposes tendermint rpc, but only passes through results after doing complete verification

BUG FIXES:

• no more silently ignored error with invalid coin names (eg. "17.22foo coin" used to parse as "17 foo", not warning/error)

0.4.1 (April 26, 2017)

BUG FIXES:

• Fix bug in basecoin unsafe_reset_X where the priv_validator.json was not being reset

0.4.0 (April 21, 2017)

BREAKING CHANGES:

• CLI now uses Cobra, which forced changes to some of the flag names and orderings

IMPROVEMENTS:

• basecoin init doesn't generate error if already initialized
• Much more testing

0.3.1 (March 23, 2017)

IMPROVEMENTS:

• CLI returns exit code 1 and logs error before exiting

0.3.0 (March 23, 2017)

BREAKING CHANGES:

• Remove --data flag and use BCHOME to set the home directory (defaults to ~/.basecoin)
• Remove --in-proc flag and start Tendermint in-process by default (expect Tendermint files in $BCHOME/tendermint). To start just the ABCI app/server, use basecoin start --without-tendermint.
• Consolidate genesis files so the Basecoin genesis is an object under app_options in Tendermint genesis. For instance:

{
  "app_hash": "",
  "chain_id": "foo_bar_chain",
  "genesis_time": "0001-01-01T00:00:00.000Z",
  "validators": [
    {
      "amount": 10,
      "name": "",
      "pub_key": [
	1,
	"7B90EA87E7DC0C7145C8C48C08992BE271C7234134343E8A8E8008E617DE7B30"
      ]
    }
  ],
  "app_options": {
    "accounts": [{
      "pub_key": {
        "type": "ed25519",
        "data": "6880db93598e283a67c4d88fc67a8858aa2de70f713fe94a5109e29c137100c2"
      },
      "coins": [
        {
          "denom": "blank",
          "amount": 12345
        },
        {
          "denom": "ETH",
          "amount": 654321
        }
      ]
    }],
    "plugin_options": ["plugin1/key1", "value1", "plugin1/key2", "value2"]
  }
}

Note the array of key-value pairs is now under app_options.plugin_options while the app_options themselves are well formed. We also changed chainID to chain_id and consolidated to have just one of them.

FEATURES:

• Introduce basecoin init and basecoin unsafe_reset_all

BREAKING CHANGES:

• Update to ABCI v0.4.0 and Tendermint v0.9.0

IMPROVEMENTS:

• Use new Tendermint /commit endpoint for crafting IBC transactions
