  • Bump to Cosmos SDK v0.53.3.

Features (non-breaking)

v0.2.0 - 2024-03-26

Consensus Breaking Changes

  • (x/warden) #77 Use uint64 IDs for Space and Keychain, instead of string bech32 addresses
  • (x/act) #55 Initial release of the shield intent engine, replacing the old boolparser and cleaning up the API
  • (x/act) #112 Store a list of referenced addresses when a new intent is created. This is useful for querying all intents that reference a given address.
  • Refactor of x/act's and x/warden's store design to improve queries performance:
    • (x/act) #117 Pin the intent definition when an Action is created instead of just referencing it. This allows faster queries "by address" by storing the list of addresses directly inside the action, instead of having to re-evaluate the linked intent for each action.

v0.1.0 - 2024-03-06

Initial release of wardend and launch of the Alfama testnet.
