v1.0.0

Namada v1.0.0 is the first stable release of the Namada apps.

MISCELLANEOUS

• updated namada libraries to libs-v0.46.1
  (#4123)

Namada libs 0.46.1

Namada 0.46.1 is a libraries patch release containing couple improvements and a bug fix in preparation for a stable apps release.

BUG FIXES

• Only write a dummy validator to CometBFT's genesis if the number of validators
  present is lower than 2. (#4116)

IMPROVEMENTS

• Improved the client's retry logic on failed shielding transactions
  to avoid resubmissions on rejections other than the MASP vp ones.
  (#4071)
• Updated the query-protocol-parameters command to display some missing
  parameters. (#4083)

MISCELLANEOUS

• Starting from the next release the Namada binary apps (namada, namadan,
  namadac and namadaw) will be versioned separately from the libraries
  (everything else including the wasm). The libraries releases will have their
  tag prefixed with "lib-" and will continue with the current versioning scheme.
  (#4117)

Namada 0.46.0

Namada 0.46.0 is a minor release containing important bug-fixes and various improvements.

BUG FIXES

• Added validation of the transaction's memo in the validity predicates to catch
  any possible tamperings. (#3960)
• fix unshielding NFT transfer via IBC
  (#4025)
• Validate validator metadata from on-chain validator creation and metadata
  changes. (#4036)
• CLI: Allow to wrap a raw tx signed by someone else.
  (#4055)
• Use the base denom in the given IBC token as it is
  (#4060)
• fix the cli command 'namada client reveal_pk' to respect the
  '--dump-tx' and '--dump-wrapper-tx' flags when present. this
  allows offline accounts to reveal their public keys to the network
  (#4061)

DOCS

• Fixed broken link to CometBFT installation instructions in README.md
  to ensure users can properly access the installation guide.
  (#4006)

FEATURES

  (#4003)
• Added more info to gas failure errors. (#4004)
• Improve the shielded sync's ledger client performance and user experience.
  (#4016)
• Avoid updating merkle paths of spent notes. This should optimize
  the synchronous path of the shielded sync on the ledger client.
  (#4018)
• The speculative shielded context now avoids updating its
  state if the transaction failed. Added a test for it.
  (#4019)
• Some small fixups learned from the dry-run: namadac
  staking-rewards-rate, namadac query-proposal, log.
  (#4021)
• Improved the display of transactions' results.

  to boot up a localnet with two genesis validators or a full node.
  (#3680)

Namada 0.43.0

Namada 0.43.0 is a minor relasing improving shielded sync and addressing some pre-genesis flow issues.

BUG FIXES

• Fix genesis bonds from implicit accounts. Now, only addresses
  of the form tnam1... are supported in balances.toml.
  (#3645)

FEATURES

• Partially addresses Issue #2900. Viewing and spending keys can now
  be given birthdays in the form of block heights which are loaded into
  shielded sync. Shielded sync will not try to decrypt a block before a
  keys birthday with said key. (#3653)
• The command namadan utils test-genesis now accepts --check-can-sign
  multi-arg that can be used with genesis addresses and/or public keys to
  verify that a pre-genesis wallet in the base directory is able to sign
  with the keys associated with the addresses or with the keys themselves.
  (#3660)

IMPROVEMENTS

• Removed parallel gas accounting.
  (#3615)
• Improve governance client side validation.
  (#3629)

  action. (#3632)
• Do not load context for namadan utils test-genesis command.
  (#3652)
• Speeds up client commands on networks with massive balances.toml
  files. Previously, to retrieve the native token of some network,
  we had to parse these giant files. Now, we only parse the
  necessary genesis toml files required to retrieve the native token.
  (#3655)

SDK

• Parallelize the shielded sync implementation in Namada.
  (#3578)

TESTING

• Added fuzz testing targets for txs in mempool, block proposals and finalize
  block. (#3445)

  (#3553)
• Improve client side checks for update-account transaction.
  (#3566)
• Do not load shed tower-abci info service.
  (#3576)

  to withdraw. Automatically submit reveal pk tx for source for shielding
  transfers. (#3594)
• Fix the behavior of the MASP VP when processing an IBC Receive message
  involves unescrowing. (#3611)

FEATURES

• Added support for Ledger wallet TCP transport.
  (#3593)

IMPROVEMENTS

• Added two new crates, namada_vm and namada_vp and removed namada crate that
  contained various loosely related code. Moved the native VP implementations
  to the relevant crates and replaced their cross-dependencies with dependency-
  injection. (#3402)
• Replaced cross-system dependencies in namada_shielded_token crate with
  dependency-injection. (#3466)
• Added a new namada_systems crate to contain abstract systems interfaces,
  previously added to core crate. Also switched to use the concrete
  storage error and result type instead of the generic associated
  type which reduces the amount of typing needed one the caller side.
  (#3472)
• Replaced cross-system dependencies in namada_governance crate with dependency-
  injection. (#3482)
• Replaced cross-system dependencies in namada_proof_of_stake crate with
  dependency-injection. (#3497)

  associated wasm payload. (#3617)

Namada 0.41.0

Namada 0.41.0 is a minor release that primarily improves gas, fixes bugs related to signature verification and a memory leak from a dependency, and includes shielded sync upgrades.

BUG FIXES

• Adds SDK builder to shielded and shielding transfers.
  (#3518)
• Workaround a leak in wasmer store.
  (#3529)
• Client fixes that include using the correct total voting power to compute a
  proposal result and also the correct voting threshold for steward proposals.
  (#3540)

  signature(s). (#3543)

CI

• Fixed a broken e2e test for db migrations. Added it to the list of e2e test to be run by the CI.
  (#3481)

IMPROVEMENTS

• Moved the signature verifications out of the masp vp and into the affected
  addresses' vps. (#3312)
• Implements phase 1 of Issue #3385

  • When fetching notes, connections and related failures should not halt shielded sync. Instead, the process
    should be restarted

  • If fetching is interrupted, the data fetched should be persisted locally so that progress isn't lost.

  • A trait for fetching behavior should be added to provide modularity

    (#3498)

• Improved the interface of the gas type. Removed the duplicated gas used from
  events. (#3428)
• Implement the phase 2 masp shielded sync client. This client uses
  a namada-masp-indexer instance to query the state of the shielded context.
  (#3456)
• Minor improvements to governance and PGF code quality, including
  template gov proposal jsons and a python script to attach wasm code.
  (#3471)
• Modified rechecks of process proposal to actually use process_proposal
  instead of process_txs. Added a caching mechanism to avoid
  running the check for a given proposed block more than once.
  (#3473)
• Expanded the scope of test vector generation and updated outdated components
  of the test vector code. (#3494)
• Removes redundant function.
  (#3502)
• Bump tendermint-rs to 0.37
  (#3506)
