Namada 0.44.0 is a minor release containing various fixes for shielded tokens, shielded sync, IBC and its interaction with shielded tokens and various other improvements.

BUG FIXES

• Support only a transparent address as a refund target of IBC shielding transfer (#3620)
• Make transfers with same source and destion a no-op. (#3675)
• Fix path to compiled WASMs that's validated during join-network. (#3694)
• Now we propagate the error coming from is_proposal_accepted instead of falling back on a default. (#3700)
• Handle errors when loading wallet file and only create a new one if not found. (#2151)
• Fixed the SDK to generate MASP transactions with the correct expiration (if provided). (#3724)
• Enable the signing logic to fall back to the hardware wallet if a secret key is not found in software wallet store. (#3730)
• The multitoken vp now checks that the involved parties validate the transaction. Improved tests and transfer code. (#3804)
• The masp ref events are now published in a single collection enforcing a correct ordering. Fixed the shielded sync command to account for multiple masp transactions in a single tx. (#3821)

IMPROVEMENTS

• Add optional height parameter to get_token_balance (#3530)

• Improved the consistency and safety of MASP events construction in protocol. (#3669)

• Reorganized some types and modules and refactored crates re- exports, error handling features and removed unused depdendencies. (#3670)

• Removed the dev dependencies of wasm-for-tests. (#3676)

• Improved the user experience of the secret key decryption process. (#3681)

• Addresses the remaining points of Issue #3307

  • Implements the OfferSnapshot ABCI call
  • Implements the ApplySnapshotChunk ABCI call
  • Adds integration tests

  (#3687)

• Improved some governance messages and cli commands arguments. (#3689)

• Updated toolchain to Rust 1.81.0. (#3690)

• Include some CLI commands for querying the total supply of any token and the effective total circulating supply of the native token. (#3691)

• Only re-exporting tendermint-rs v0.37 modules. (#3697)

• Made the disposable-gas-payer cli arg specific to some transactions. (#3699)

• Optimize the format of snapshots taken for state syncing purposes. Snapshots are taken over the entire RocksDB database, packaged into a zstd compressed tar archive, and split into 10 MB chunks. (#3701)

• Implement serde::Serialize for GovernanceParameters, PosParams, OwnedPosParams (#3702)

• Change the quorum for voting on a default governance proposal from 2/3 to 40%. (#3703)

• Improve the format of dumped txs. Added command to generate signature without requiring a network connection. (#3715)

• Moved governance shell sub-module into governance crate using dependency- injection. (#3718)

• If an additional reveal_pk transaction is required, the client now groups it with the actual transaction into a single batch instead of submitting it separately. (#3720)

• Improve the proposal result query to be more descriptive and detail the validator voting period. Fix some other small logging bugs. (#3728)

• Switched to use typed ChainId instead of a string in all fn get_chain_id. (#3733)

• Add an RPC endpoint for the consensus validator set in the SDK. (#3734)

• Update tendermint-rs, ibc-rs and tower-abci (#3735)

• Refactored token transfer functions and fixed checks for no-op conditions. (#3736)

• Support dynamically joining ledger managed tasks. With this change, adding or removing managed tasks from the ledger should be a far easier process to contend with. (#3741)

• Factored most of the masp code out of the sdk and into shielded token crate. These required the creation of two futher crates: "namada_io" and "namada_wallet". (#3744)

• Increased the gas cost for storage consumption and improved gas tracking for masp fee payments. (#3746)

• Upgrade CometBFT to v0.37.11. (#3751)

• Remove namada-relayer from the build. (#3752)

• Improve error and help messages to clarify that a .tx file is expected as input to --tx-path for a custom tx. (#3757)

• Miscellaneous improvements and bug fixes to the dry run command. (#3758)

• Check the string length of the validator name in provided metadata. (#3779)

• Improve the CLI query-protocol-parameters. (#3788)

• Improved the invariants and the usage of the Gas type. (#3792)

• Propagate "std" feature from SDK to wallet crate. (#3795)

• Improve the logging options for querying MASP conversions. (#3805)

• When calling init chain, we now verify that the native token alias has masp parameters set. (#3806)

• Refactored most native VPs to be agnostic to VP environment (WASM or native). (#3807)

• Adds an SDK and CLI tool to estimate the latest annual staking rewards rate. (#3816)

• Reduced the number of a tx event's masp attributes to a single one. (#3826)

• Remove relayer help messages from namada binary. (#3830)

• Let user customize the pre-genesis chain-id via environment variable (#3833)

• Validate a chain ID of genesis on ABCI InitChain request prior to applying it to ensure it's not been tampered with. (#3843)

TESTING

• Clean IBC E2E tests and refine IBC client upgrade test with Gaia (#3601)
• Updated the gaia e2e tests to use the MASP internal address instead of the payment address as the receiver of an IBC shielding transaction. (#3626)
• Augment the functionality of gen_localnet.py with the ability to generate full node base directories. Moreover, add a new script to boot up a localnet with two genesis validators or a full node. (#3680)
