v1.2.1 - 2023-06-14

State Machine Breaking

Release version with State Machine Breaking from v1.2.0 Please upgrade according to the team's notice

Bug Fixes

Apply Barberry patch & Bump SDK to v0.46.13

v1.2.0 - 2023-04-03

Upgrades

  • Bumped cosmos-sdk version to v0.46.10
  • Bumped tendermint version to v0.34.26
  • Bumped go version to v1.19
  • Bumped ibc-go to v5.2.0
  • Bumped ics23 to v0.9.0

Improvements

  • Made the app independent of the ignite:
  • created params directory which holds chin encoding, denom and address prefix config
  • removed cosmoscmd App interface
  • created CMD functions for correct chain start and initialization
  • deleted module message handlers
  • Added end-to-end testing framework that can be used for full testing functionality (this framework is based on Osmosis E2E testing suite)
  • Migrated all modules params from using x/params module to using simple KVStore (cosmos-sdk ADR)
  • (x/cfevesting) Renamed address field of the AccountVestingPools object to owner
  • x/cfeminter Module params refactoring:
  • cfeminter params structure changed - removed MinterConfig and moved mint_denom and Minter array directly to Params
  • changed the configuration logic for individual minters - instead of setting one of the LinearMinting or ExponentialStepMinting fields to a specific value, and the other to null, the configuration now includes one config field that accepts the MinterConfigI interface. LinearMinting and ExponentialStepMinting implement this interface which allows to set one specific configuration for minter.
  • (x/cfevesting) Vesting cession:
  • added MsgSplitVesting to split the vesting and transfer it to the second account
  • added MsgMoveAvailableVesting and MsgMoveAvailableVestingByDenoms to move available vesting from one account to another

  • Founders accounts vesting period extension by one year
    • from: lockup: 1 year, vesting: 2 years
    • to: lockup: 2years, vesting: 2 years

Bug fixes

  • (x/cfevesting) If there are any vesting pools, changing the vesting denom is not possible
  • (x/cfeminter) When changing minters via proposal, it checks if there is a minter in the new configuration with a sequence_id that is currently in cfeminter state
