BUG FIXES

  • Wallet: respect the optional bip39-flag for key derivation. (#2489)

IMPROVEMENTS

  • Wallet: print the generated payment address. (#2490)

BUG FIXES

  • Fixing several bugs in how governance and pgf transactions are handled and validated. (#2459)

IMPROVEMENTS

  • Modified the MASP VP to validate the changed storage keys instead of the Transfer object. (#2452)
  • MASP inflation for a given token now is adjusted based on a target amount of total locked (shielded) tokens rather than a ratio relative to some total supply. (#2460)
  • Add an address CLI arg that defaults to the native token. (#2467)

SDK

  • Modified scan_tx to require the set of changed keys instead of Transfer. fetch_shielded_transfer now returns the set of changed keys instead of Transfer. (#2452)

  • Introduce a memo field, to allow including arbitrary data inside of transactions. (#2358)
  • Include validator avatar url in their medatada (#2359)
  • Removed masp data from storage. Updated the client to query the cometBFT rpc endpoints. (#2363)
  • When constructing a governance proposal the id is now a required field. (#2365)
  • Added validator's consensus key look-up to client find-validator command, which now also accepts a native validator address. (#2368)
  • Fix the function bond_amount to more accurately account for slashes. (#2374)
  • The MASP VP now validates the tx expiration. (#2375)
  • Removed the hardcoded sentinel key of MASP. (#2376)

v0.29.0

Namada 0.29.0 is a minor release that introduces the light SDK, upgrades the MASP and CLI, and includes other fixes and refactors of the PoS, IBC, and Ethereum Birdge modules.

BUG FIXES

  • Prevents double-spending in masp by adding a nullifier set. (#2240)
  • Updates masp tx to store the notes and the native vp to validate them and the anchors. (#2244)
  • Updates the masp vp to validate the convert description's anchor. (#2248)
  • Client: Check that transaction is successful before taking further actions. (#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. (#2222)
  • Fee amounts in transaction wrappers are now denominated to facilitate hardware wallet support. (#2245)

  • 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)
  • Added light sdk (#2220)
  • Improved the TxResponse type. (#2276)
  • Removed useless epoch for fee unshielding. (#2282)

TESTING

  • Added e2e test for change-consensus-key command. (#2218)

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)

v0.28.1

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)

v0.28.0

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)

  • Print more context from eyre error types. (#2132)
  • Require to verify ownership of all validator keys when initialized on-chain. (#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)

  • refactoring IBC and remove IBC token denomination (#2062)
  • Upgraded to upstream ibc-rs and tendermint-rs crates. (#2084)
  • Updated the gas costs. Introduced a local validator configuration parameter to set the accepted tokens and amounts for fees. (#2091)
  • Moved the inner transaction replay check at execution time. (#2104)
  • Removed "abcipp" and "abciplus" features and "abcipp"-only code. (#2112)

SDK

  • Updated the LedgerProposalVote display method to account for the new Abstain vote variant. (#2128)

v0.25.0

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)

In this PR, rewards are calculated and stored, but they are not yet applied to voting powers or considered when unbonding and withdrawing. (#714)
  • Implements governance custom proposals (#1056)
  • Adds expiration field to transactions (#1123)
  • Added a rollback command to revert the Namada state to that of the previous block. (#1187)
  • Introduced a new ledger sub-command: run-until. Then, at the provided block height, the node will either halt or suspend. If the chain is suspended, only the consensus connection is suspended. This means that the node can still be queried. This is useful for debugging purposes. (#1189)

  • Fixed the PrefixIter order of iteration in the write- log to always match the iteration order in the storage. (#1141)
  • Fixed the init-chain handler to stop committing state to the DB as it may be re-applied when the node is shut-down before the first block is committed, leading to an invalid genesis state. (#1182)
  • Fixed an issue in which a validator's stake and validator sets data gets into an invalid state (duplicate records with incorrect values) due to a logic error in clearing of historical epoch data. (#1191)

FEATURES

  • Added a lazy set collection. (#1196)

IMPROVEMENTS
