Namada 0.20.0 is a minor release addressing several improvements to the PoS system and the ledger stability.

BUG FIXES

• Fix genesis faucet_withdrawal_limit parser to respect tokens' denomination. (#1667)
• PoS: ensure that the size of genesis validator set is limited by the max_validator_slots parameter. (#1686)
• Fix inconsistency state before commit (#1709)
• PoS: Fixed an epoch boundary issue in which a validator who's being slashed on a start of a new epoch is disregarded during processing of block votes. (#1729)

IMPROVEMENTS

• PoS: purge validator sets for old epochs from the storage; store total validator stake (#1129)
• Added a reusable token balance query method. (#1173)
• Replaced file-lock with fd-lock dependency to support Windows build. (#1605)
• Added a command to wait for the next epoch: client utils epoch-sleep. (#1621)
• Added a client query for validator-state and improved the slashes query to show more info. (#1656)
• Removed associated type on masp::ShieldedUtils. This type was an attempt to reduce the number of generic parameters needed when interacting with MASP but resulted in making code re-use extremely difficult. (#1670)
• Removed impl From<u64> for EthBridgeVotingPower and replaced it with a TryFrom. (#1692)
• Updated sysinfo dependency. (#1695)
• Refactored storage code to only use an immutable reference when reading and writing to a batch. (#1717)

MISCELLANEOUS

• Replaced token sub-prefix with a multitoken address and native VP for IBC and ETH bridge. (#1693)
• PoS: Keep the data for last two epochs by default. (#1733)
• Refactored CLI into libraries for future re-use in integration tests and to enable generic IO. (#1738)

TESTING

• Added integration testing infrastructure for node, client and the wallet and replaced MASP E2E tests with integration tests. (#1714)
