Namada 0.38.1

Namada 0.38.1 is a patch release that fixes a license issue with the last minor release needed to build binaries in CI.

Namada 0.38.0

Namada 0.38.0 is a minor release that upgrades the MASP and events and also cleans up dependencies.

BUG FIXES

• Fixed the fee collection logic in finalize_block to match that of
  process_proposal. (#3075)

IMPROVEMENTS

• Improved masp vp verification to run in parallel.
  (#2972)
• Removed any dependency on the specific transaction data from the masp vp.
  (#3232)
• Add a new event attribute facility to track events to their origin
  in Namada's source code. This is useful for debugging purposes.
  (#3268)
• Include the used MASP randomness parameters in the test vectors.
  (#3296)
• Replaced unmaintained config-rs to an unreleased version
  that replaces its also unmaintained yaml dependency.
  (#3305)
• Upgrade wasmer vm to upstream version 4.3.1,
  moving away from the forked code based on version
  2.3.0.
  (#3308)
• Allow nodes to schedule a migrations json to be read and run to facilitate hard-forking. This is done by
  taking a migrations json and passing the path, a hash of the contents, and a block height to the node when
  starting the ledger. (#3310)
• Store IBC denom when minting the IBC token
  (#3317)
• Switched from wee allocator to rlsf for WASM.
  (#3331)

Namada 0.37.0

Namada 0.37.0 is a minor release that adds replay protection entries to consensus and enables merklizing data without diffs.

FEATURES

• Enable to write data to be updated in the subspace and Merkle tree, but not to
  be updated in diffs (#3293)

IMPROVEMENTS

• Revert IBC transaction wasm not to use host_env function.
  But it required to enable floating-point support again
  (#1831)
• Audit TODOs in the codebase.
  (#3234)
• Replay protection entries need to be verifiable and thus should contribute to the app hash. This PR makes
  a cryptographic commitment to all replay protection entries (the root of some implicit merkle tree) which is itself
  merklized. (#3284)

Namada 0.36.1

Namada 0.36.1 is a patch release that updates the Rust toolchain to 1.78.0 and fixes a couple minor issues with the last minor release.

BUG FIXES

  (#3287)

IMPROVEMENTS

• Updated Rust toolchain to v1.78.0.
  (#3254)

Namada 0.36.0

Namada 0.36.0 is a minor release includes various improvements, refactorings, dependencies clear-up and updates, and a new feature that enables to batch transactions.

BUG FIXES

  (#2817)
• Harden the implementation of BorshDeserialize on ProposalBytes.
  Moreover, avoid using magic numbers when configuring CometBFT.
  (#3220)
• Default to consensus minimum gas price for some token
  when the node-local value set by a validator is lower.
  (#3228)
• Do not submit a tx to reveal a PK when --force flag is used with a
  transaction. (#3245)

FEATURES

• Introduced transaction batches.
  (#1356)

IMPROVEMENTS

• Upgrade docker base images to Debian 12 (Bookworm) (#2975).
• Make the internals of ValueSum (in the masp crate) private so we know that invariants of representation are maintained. (#3195)

  (#3209)
• Sanitized unchecked arithmetics and conversions in the codebase.
  (#3214)

  (#3217)
• Dependency cleanup: remove unused ones, upgrade those with
  security vulnerabilities, reduce the number of transitive deps.
  (#3218)
• Bump tendermint-rs, tower-abci and ibc-rs
  (#3225)
• Extends claps Arg and Command types with namada traits. These add configurable line wrapping and
  hyphenation policies. Also sets help to always be on the next line, but this is easily changeable later.
  (#3226)
• Removed the remaining references to ferveo.
  (#3241)
• Lint for left-over debug and print statements.
  (#3257)
• Remove unused WASM memory export.

BUG FIXES

• Fix the setting of the last update field in an Epoched data structure.
  (#2667)
• Use indexmap maps and sets in favor of std collections, to avoid
  iteration order related bugs in the state machine code of Namada.
  (#2685)
• Fixed the StorageRead implementation and vp host functions to ignore
  temporary writes. (#2735)
• Fix the balance query not to show ibc tokens as default
  (#2809)
• Adjusts the tx allowlist check to not prevent fee payment.
  (#2819)
• Reduce the gas cost of prefix iterator in IBC transactions
  to match the cost of prefix iterator elsewhere.
  (#2848)
• Fix client bug that now ensures that a validator with
  delegations but no self-bonds can vote in governance.
  (#2877)
• Only use addresses from first storage key segments to
  determine which VPs should be triggered by storage changes.
  (#2928)
• Replaced DB key-val diffs pruning of non-persisted keys that searched for the
  last diffs and was degrading throughput with a separate DB column family that
  is pruned on every block.
  (#2964)

FEATURES

• Support NFT transfer over IBC
  (#2316)
• IBC rate limit for deposits into and withdrawals out of Namada
  (#2552)
• Add ibc-token command to get a list of IBC tokens
  (#2729)
• Removes offline governance as a proposal option.
  (#2803)
• Add a parameter to enable/disable native token transfers
  (#2842)

  (#2931)
• Prohibit jailed or inactive validators from voting in governance.
  (#3004)

IMPROVEMENTS

• IBC shielded transfer with Hermes support
  (#2449)
• Remove last staked ratio and pos inflation amount from
  Parameters and initialize them in pos genesis initialization.
  (#2559)
• Only process 1 slash per validator per block height.
  (#2574)
• Refactor inflation with a standalone PD controller module. Then the
  PoS and shielded inflation modules are wrappers around this controller.
  (#2575)
• Instead of having every user tx be executed across two blocks, the first executing a wrapper and the
  second executing the main payload, this change makes it so that the entire tx is executed in a single
  block (or rejected). (#2627)
• Only load governance proposals on a new epoch right before execution.
  Decoupled the logic from the Shell and implemented in the gov crate.
  (#2630)
• Adds a transaction's code and data section hashes as additional
  sources of entropy, to compute an established account's address.
  (#2781)
• Refactor the events code in Namada. Now, we emit events
  with type safe wrappers around the events' attributes.
  (#2787)
• Split up WASM transaction and validity-predicates into individual crates to
  improve build time. (#2795)
• Avoid reconstructing wasm result buffer with unsafe code.
  (#2813)
• Improved the gas metering system to track gas at runtime in wasm.
  (#2838)
• Limit the character length of the validator metadata strings.
  (#2845)
• Use clippy to disallow usage of fns to get current date/time unless explicitly
  allowed. (#2849)
• Replace eyre!() errors with namada_storage errors.
  (#2852)
• Commit gas costs of applied transactions to new commit-only merkle tree store.
  (#2926)
• Remove unnecessary decimal digits in Ledger test vectors.
  (#2932)
  This PR moves many e2e tests over to integration test. In the future, it may be possible to move more
  tests over. Moving some of these tests over revealed issues and these have also been resolved,
  including #2927. (#2933)
• Some transactions now use temporary storage (only kept for the duration of
  the tx execution and VPs validation) to indicate what actions were applied to
  validity predicates that use the information to decide who has to authorize
  the transaction. (#2934)
• Change the return type of a VP's predicate function to a Result of unit or
  some error. In case Namada users perform invalid state changes, they should
  be met with more descriptive error messages explaining the cause of their tx's
  rejection. (#2940)
• Return error messages from tx execution, instead of aborting execution with no
  context. (#2958)
• Simplified gas metering for code compilation and validation.
  (#2982)
• For inflation computations and the relevant RPC, don't
  include the PGF balance in the total native supply
  (#3002)

• Disable Ethereum Bridge functionality at compile time.
  (#2602)

  (#2729)
