BUG FIXES

• Prevents double-spending in masp by adding a nullifier set.
  (#2240)

  anchors. (#2244)
• Updates the masp vp to validate the convert description's anchor.
  (#2248)

  (#2279)
• Non-Namada token can be given to ibc-gen-shielded
  (#2308)
• Make the ledger wait for genesis before starting up any processes (#2310)

FEATURES

• A new client command has been added that takes a set of pre-genesis template files, validates them,
  and runs them through init_chain. All errors are collected into a report. (#2255)
• The wallet CLI structure has been significantly reworked and simplified.
  Alias argument is now obligatory for key generation / derivation
  commands. Feature of raw (non-HD) key generation has been restored,
  which was removed in the previous release. Key export / import
  functionality for both transparent and shielded key kinds has been
  implemented. Additionally, several other improvements have been made.
  (#2260)
• IBC transfer from a spending key
  (#2321)

IMPROVEMENTS

• Emit Bridge pool transfer status update events from FinalizeBlock
  (#1995)
• Refactored module dealing with Tendermint configuration.
  (#2127)
• The default implicit and established user account VPs now
  require valid signature(s) for unknown storage changes.
  (#2213)
• Allowed the unshielding of previous epochs assets from the masp.

• Move the inflation code for PoS and PGF into their own native modules.
  (#2295)
• Improved validation on transaction's expiration. Added an expiration for MASP
  transfers. (#2315)

IMPROVMENTS

• Previously, a hardcoded set of tokens were expected to be used in Masp conversions.
  If these tokens did not have configs in genesis, this would lead to a panic after the first
  epoch change. This PR fixes this to use the tokens found in genesis belonging to the MASP
  rewards whitelist instead of hardcoding the tokens.
  (#2285)

SDK

• Introduce a method to query the status (pending, relayed or expired) of Bridge
  pool transfers (#1995)

  (#2218)

Namada 0.28.2

v0.28.2

Namada 0.28.2 is a patch release that fixes a stack overflow issue for nodes.

BUG FIXES

• Fixed DB prefix iterators to avoid iterators with key that don't match the
  given prefix, which was triggering recursive call that was growing stack with
  every new applied tx and on reading state from disk on start-up. Replaced
  recursion from RocksDB that was growing stack size with a loop.
  (#2325)

Namada 0.28.1

Namada 0.28.1 is a patch release that makes improvements to the MASP, SDK, merkle trees, and chain initialization conditions.

BUG FIXES

• Fix sdk compilation when using async-send feature flag.
  (#2261)
• Added back missing changed storage keys in transaction results.
  (#2263)
• Fix to skip pruning BridgePool Merkle trees when no signed nonce
  (#2264)
• Initialize token total supply to zero at init chain.
  (#2270)

IMPROVEMENTS

• Preload and cache MASP verifying keys on ledger start-up.
  (#2272)
• Now join-network will try to look for non validator wallet in more places.
  (#2273)

Namada 0.28.0

Namada 0.28.0 is a minor release that improves the genesis setup to allow signing with hardware wallet and contains various improvements including validator liveness jailing, accounts simplifications, bug fixes, stability improvements and more.

BUG FIXES

• Fix the start block height of the first epoch.
  (#1993)
• Fix Ethereum event validation/state updates when more than one validator is
  running the chain (#2035)
• Fix possible underflow in MASP rewards calculation.
  (#2230)

IMPROVEMENTS

Allow the ethereum oracle to be activated / deactivated via config
updates sent from ledger. This allows governance to shut down the
ledger without restarts. Otherwise, disconnecting from Ethereum will
result in the ledger crashing.
(#1764)

• Prune merkle tree of bridge pool
  (#2110)
• Revert the chain ID format by upgrading ibc-rs to 0.48.1
  (#2153)
• Changed pre-genesis established addresses to be derived from their data.
  Improved signing of pre-genesis transactions to use the same format as
  regular transactions. Genesis token balances now can be directly assigned to
  established addresses. (#2186)
• Combined the user and the validator VP into one.
  (#2202)
• Charge gas for network usage.
  (#2205)
• A new tx_become_validator replaces tx_init_validator. This tx doesn't
  initialize a new account and instead it modifies an existing established
  address to become a validator. This currently requires that there are no
  delegations on the source account before it can become a validator (if there
  are some, they have to be unbonded, but they don't have to be withdrawn).
  A new client command become-validator is added that requires an --address.
  The client command init-validator is kept for convenience and updated to
  send tx_init_account tx before tx_become_validator.
  (#2208)
• Increase hardware wallet support in the CLI
  (#2209)
• Handle errors on loading WASMs from file-system compilation cache.
  (#2215)
• Implement a CLI query for available rewards from a bond,
  and improve the bond amount for rewards computation
  (#2217)
• Fix bug in client to allow for unjailing a validator
  that was jailed for missing liveness requirements
  (#2246)

MISCELLANEOUS

• Upgraded borsh dependency to v1.2.0.
  (#2233)

SDK

• Removed uses of lifetimes in the SDKs Namada trait and implementation
  (#2225)
• Added Send trait support to the SDK to allow its use in more multithreaded
  contexts. (#2235)

Namada 0.27.0

Namada 0.27.0 is a minor release that incorporates the remaining essential proof-of-stake features, updates the MASP and transaction functionality, and provides some additions to the SDK.

BUG FIXES

• Fix a feature flag to compile namada_sdk
  (#2164)
• Fix to get the proof even if no height is specified
  (#2166)

  (#2163)
• Improve the validator VP to ensure that only the validator themself
  can execute transactions that manipulate its own validator data
  (#2169)
• Various improvements to the PoS code, including adding a panic on a slashing
  failure, some more checked arithmetics, aesthetic code cleanup, and fixing a
  bug in is_delegator. (#2178)
• Added type tags to transactions to enable hardware wallets
  to fully decode transactions even after minor Namada updates.
  (#2182)
• Save MASP conversion state to the state storage instead of the diffs
  (#2189)

MISCELLANEOUS

• Removed catching of panics from PoS VP.
  (#2145)

SDK

• Masp as internal address. Updated aux_signing_data
  to return no key and 0 threshold if owner is masp.
  (#2051)
• A high level function new_redelegate is added to the sdk to allow developers
  to make and submit redelegation functions from the minimum number of arguments
  required (#2140)

  (#2046)
• Switch to a more compact representation in Namada's transparent
  addresses, and change all bech32m HRPs to their mainnet equivalent
  (#2060)
• refactoring IBC and remove IBC token denomination
  (#2062)
• Upgraded to upstream ibc-rs and tendermint-rs crates.
  (#2084)

  (#2115)
• Upgraded to upstream tower-abci version.
  (#2141)

Namada 0.25.0

This release includes only the new genesis flow.

FEATURES

• Added bech32m string encoding for common::PublicKey and DkgPublicKey.
  (#2088)
• Added --pre-genesis argument to the wallet commands to allow to generate
  keys, implicit addresses and shielded keys without having a chain setup. If
  no chain is setup yet (i.e. there's no base-dir or it's empty), the wallet
  defaults to use the pre-genesis wallet even without the --pre-genesis
  flag. The pre-genesis wallet is located inside base-dir in
  pre-genesis/wallet.toml.
  (#2088)
• Reworked the genesis templates, setup and related utils commands.
  (#2088)
