[dependabot[bot]]

Bumps cosmossdk.io/core from 0.5.1 to 0.7.0.

Changelog

Sourced from cosmossdk.io/core's changelog.

0.7.0 (October 11, 2017)

BREAKING CHANGES:

• Everything has changed, and it's all about to change again, so don't bother using it yet!

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)
