Namada 0.20.1

Namada 0.20.1 is a patch release addressing a bug in the inflation mechanism and minor ledger improvements.

BUG FIXES

• Ensure that each crate in the workspace can be built with default features.
  (#1712)
• Fixed transparent balance query when only an owner address is specified without
  an explicit token. (#1751)
• Fixes how PoS inflation is calculated.
  (#1756)
• Fixes the ordering for I256 type.
  (#1763)

IMPROVEMENTS

• Removed the associated type for an address from trait NativeVp.

Namada 0.20.0

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)

  (#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.

  TryFrom. (#1692)
• Updated sysinfo dependency.
  (#1695)

  ETH bridge. (#1693)

  (#1604)

BUG FIXES

• Do not add address if it already exists in the wallet.
  (#1504)
• When processing slashes, bonds and unbonds that became active after
  the infraction epoch must be properly accounted in order to properly
  deduct stake that accounts for the precise slash amount. A bug
  is fixed in the procedure that properly performs this accounting.

  transactions. (#1522)

  mode after a successful init-validator transaction.

Namada 0.17.1

Namada 0.17.1 is a scheduled minor release featuring several improvements to the slashing mechanism,
wallet address derivation, transaction structure and the ledger stability.

BUG FIXES

• Persists a newly added storage field for epoch update blocks delay to be
  available after node restart when not None which may break consensus.
  (#1455)
• Client: Fixed an off-by-one error to stop waiting for start or catch-up when
  max tries are reached. (#1456)

  PoS address rather than being transferred to the Slash Pool address. This PR
  also includes significant testing infrastructure, highlighted by the PoS state
  machine test with slashing. (#892)
• Implements HD wallet derivation / recovery from a given mnemonic code
