Changelog

[v0.13.0]

  • Hard Protocol - Introduces borrowing functionality to HARD protocol. See full spec

Breaking changes

#750 Update CDP liquidations to allow for liquidation by external keeper.

#751 Use accumulators for CDP interest accumulation.

#780 Moves HARD token distribution from harvest module to incentive module. All HARD supply, borrow, and delegator reward objects and claims are moved to the incentive module.

[v0.12.0]

#701 Patch issue that prevented atomic swaps from completing successfully

[v0.11.0]

#591 Add a raw-params cli method to query raw parameter values for use in manual verification of gov proposals.

#596 Add REST client and CLI query to get module account information for the CDP module

#590 Add CLI query to return kavadist module account balance

#584 Add REST client and CLI queries for kavadist module

#578 Add v0.3 compatible REST client that supports

#629 Add CDP collateral type as a field for CDPs and collateral parameters.

#658 Add harvest v1 and HARD token distribution schedule

Breaking changes

  • CDPs have an additional field, Type, which is a string that represents the unique collateral type that this CDP holds. This enables, for example, a single denom such as 'bnb' to have two CDP types, 'bnb-a' and 'bnb-b'.
  • CollateralParam has an additional field, Type, which is a string that represents the collateral type of CDPs that this collateral parameter governs. It must be non-empty at genesis or when altering CDP fields. It is UNSAFE to alter the type of an existing collateral param using unchain governance.
  • CDP messages must specify the collateral type 'bnb-a', rather than the denom of the cdp.
  • In the incentive module, fields previously named Denom have been changed to CollateralType. Previously, 'Denom' was validated to check that it satisfied sdk.ValidateDenom, now, the validation checks that the CollateralType is not blank.
  • Incentive module messages now require the user to specify the collateral type ('bnb-a'), rather than the denom of the cdp ('bnb')

#598 CLI and REST queries for committee proposals (ie kvcli q committee proposal 1) now query the historical state to return the proposal object before it was deleted from state #625 The Cosmos SDK has been updated to v0.39.1. This brings with it several breaking changes detailed in their changelog. Notably account JSON serialization has been modified to use amino instead of the Go stdlib, so numbers are serialized to strings, and public keys are no longer encoded into bech32 strings. Also pruning config has changed: pruning=everything and pruning=nothing still work but there are different flags for custom pruning configuration.

v0.8.1 kava-3 Patch Release

This version mitigates a memory leak in tendermint that was found prior to launching kava-3. It is fully compatible with v0.8.0 and is intended to replace that version as the canonical software version for upgrading the Kava mainnet from kava-2 to kava-3. Note that there are no breaking changes between the versions, but a safety check was added to this version to prevent starting the node with an unsafe configuration.

Bugfix

The default tendermint pruning strategy, pruning="syncable" is currently unsafe due to a memory leak that can cause irrecoverable data loss. This patch release prevents kvd from being started with the pruning="syncable" configuration. Until a patch for tendermint is released, the ONLY pruning strategies that are safe to run are everything (an archival node) or nothing (only the most recent state is kept). It is strongly recommended that validators use pruning="nothing" for kava-3. It is expected that a patch to tendermint will be released in a non-breaking manner and that nodes will be able to update seamlessly after the launch of kava-3.

The steps for upgrading to kava-3 can be found here. Please note the additional section on pruning.

v0.8.0 kava-3 Release

This version is intended to be the canonical software version for upgrading the Kava mainnet from kava-2 to kava-3. As a result, no subsequent versions of Kava will be released until kava-3 launches unless necessary due to critical state-machine faults that require a new version to launch successfully.
