Namada 0.40.0

on GitHub

Namada 0.40.0 is a minor release that makes many important improvements to shielded actions, DB snapshotting capabilities, batched transactions, and much more.

BUG FIXES

• Update native token total supply with MASP rewards.
  (#3375)
• Increase the lifetime of disposable signing keys from 5 minutes to 1 week.
  (#3378)
• Our DateTimeUtc type allowed a relaxed representation of RFC3339 strings.
  We now enforce a string subset of this format, to guarantee deterministic
  serialization. (#3389)
• Fix to decode ibc-rs transfer messages
  (#3404)
• Add replay protection to MASP-IBC transactions.
  (#3409)
• Respect --wasm-dir on init-network.
  (#3432)
• Fix IBC shielding transfer for the receiver not to be replaced by a malicious
  relayer (#3438)
• Fixed MASP witness data malleability in the Tx
  (#3463)

FEATURES

• Reworked transparent and masp transfers to allow for multiple sources, targets,
  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.
  (#3343)

• Remove the max_expected_time_per_block genesis parameter.
  (#3366)

• Refactored checked assign arithmetic operations to use smooth-operator macro.
  (#3374)

• Store total MASP rewards and print them in the conversions query.
  (#3375)

• Remove the check on the maximum number of signatures allowed per transaction
  (#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)

• Remove the requirement that the proposal voting period
  is some integer multiple of the minimum voting period.
  (#3390)

• Include the gas scale as a protocol parameter that is
  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)
