  (#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)

  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)

  (#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

  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)

  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)

  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)

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)

  (#3375)
• Increase the lifetime of disposable signing keys from 5 minutes to 1 week.
  (#3378)

  (#3404)
• Add replay protection to MASP-IBC transactions.
  (#3409)
• Respect --wasm-dir on init-network.

  tokens and amounts. (#3356)
• Added support for fee payment directly from the MASP pool.
  (#3393)

IMPROVEMENTS

• Moved up the check on the sapling value balance in the masp vp.
  (#2721)

• Queries methods now requests TryInto trait bound for block heights to reduce
  the conversion error. (#2891)

• Miscellaneous code optimizations.
  (#3192)

• Added a namada complete command to generate shell completions. This command
  requires --shell with one of:

  • bash
  • elvish
  • fish
  • powershell
  • zsh
  • nushell

  To use in e.g. bash, run namada complete --shell bash > /usr/share/bash-completion/completions/namada.bash.

  (#3380)

• Resolves the first two points of Issue #3307:

  • Add the ability to create chunkable snapshots to our rocksdb implementation
  • Spawn a background task to create snapshots are certain blockheights

  Specifically adds a config parameter that indicates after how many blocks a
  snapshot should be created. If set, then on the corresponding calls to commit,
  a background task is spun up that takes a snapshot of rocksDB and writes it
  in a convenient format to a file. This file contains metadata of how to be
  broken up into chunks. Once a new snapshot is created, older snapshots are
  removed. (#3383)

• Addresses the third point and part of the fourth point of Issue
  #3307

  • Adds chunking logic to snapshots
  • Implements the ListSnapshots ABCI call
  • Implements the LoadSnapshotChunk ABCI call

  (#3386)

  mutable via governance rather than as a hard-coded constant.
  (#3391)

• Upgrade the library used to communicate with hardware wallet
  (#3412)

• Index batched txs via their wrapper and commitment hashes.
  (#3416)

• Moved shielded tx validation out of the SDK crate into shielded token crate.
  (#3419)

• Enforce an upper limit on the number of PGF stewards allowed to exist at a
  given time. (#3442)

• Combined the various Transfer formats into one general one.
  (#3446)

• Introduced a local configuration parameter to allow nodes to
  rerun the process proposal checks before block finalization.
  (#3448)

TESTING

• Adds additional test coverage to batch tx events emission, to make
  sure we correctly build a batch of inner tx events from a batched tx.
  (#3401)
• Change the IBC E2E testing config
  (#3455)

Namada 0.39.0

Namada 0.39.0 is a minor release that primarily abstracts the different kinds of transfer transactions and makes upgrades to the MASP and VPs.

  • unshield (from shielded to transparent)
    (#3297)
• Avoid growing wasm memory when performing read-only accesses.
  (#3315)
