  PoS state changes for collections with variable size with a bounded gas cost.
  (#16)
• The unbonding action has been updated to affect validator voting power at
  pipeline offset and become withdrawable starting from pipeline + unbonding
  offset. (#366)

• Renamed PoS active and inactive validator sub-sets to consensus and
  below_capacity sets.
  (#787)

  (#1054)

TESTING

• Add e2e tests for multitoken transfers

calculation logic.

BUG FIXES

  respect the PoS tm_votes_per_token parameter.
  (#1083)

Namada 0.13.2

Namada 0.13.2 is a bugfix release addressing issues with the 0.13
release series.

BUG FIXES

• Fixes testnet wrapper fee checks
  (#1019)

  (#1062)

Namada 0.13.0

Namada 0.13.0 is a scheduled minor release.

BUG FIXES

• Fix the commission rate change wasm test, which failed because an arbitrary
  value for a new rate was allowed that could be equal to the previous rate.
  (#965)

BUGS

• Removed 'rev_iter_prefix' from storage API as its implementation
  depends on RocksDB and it doesn't work as expected.
  (#912)

FEATURES

• Add a --time argument to the node to specify the time the node should start.
  (#973)
• Reduce the block size for transactions to 5 MiB.
  (#974)

IMPROVEMENTS

• Disable 'Send' on async traits that don't need 'Send'
  futures. This allows to use them with 'wasm-bindgen'.
  (#900)
• Binary search ledger storage keys to match faster.
  (#903)
• Make queries data structures public for inclusion in rustdoc.
  (#909)
• Add a macro to derive storage keys from a struct.
  (#926)
• Added a basic fee implementation for testnet.
  (#962)
• Hide the explicit lifetime from StorageRead trait.
  (#966)
• Allow to set the tracing format with NAMADA_LOG_FMT env var to either full
  (default), json or pretty. (#968)
• Added an optional PoW challenge to the wrapper transactions for testnets,
  to allow to submit transactions without having enough balance to cover
  the minimum transaction fee and to withdraw tokens from a faucet account.
  (#969)
• Add genesis parameter to control wrapper transaction fees.
  (#972)
• Add a max_proposal_bytes parameter to the ledger.
  (#975)

MISCELLANEOUS

• Update tendermint to v0.1.4-abciplus.
  (#667)

TESTING

• Run fewer cases on update_epoch_after_its_duration, for a faster test suite.
  (#876)
• Use the correct options (--gas-amount, --gas-
  token) in the ledger_txs_and_queries E2E test.
  (#911)

Namada 0.12.2

Namada 0.12.2 is a hotfix release, limiting transactions included in a
block by size.

BUG FIXES

• Limit block space to under Tendermint's limit, and limit transactions included
  in a block by their size. (#952)

MISCELLANEOUS

• Don't attempt to include matchmaker DLLs, which no longer exist, in release
  packages. (#943)
• Include license information in release binary tarballs.
  (#945)

Namada 0.12.1

Namada 0.12.1 is a hotfix release, fixing a node crash on malformed
transactions to the MASP.

BUG FIXES

• Avoid panicking unwrap()s in vp_verify_masp, to prevent crashing the node on
  malformed transactions. (#942)

Namada 0.12.0

Namada 0.12.0 is a scheduled minor release.

Tendermint

• 0.1.4-abciplus

Docker

• Image

CI

• Run make check-abcipp in CI (#824)
• Run Ethereum bridge CI against more branches
  (#834)

DOCS

• Adds specs for replay protection
  (#440)
• Adds specs for multisig accounts
  (#680)

IMPROVEMENTS

• Allow sign extension opcodes in WASM
  (#833)
• Remove the MerkleValue type and just use byte slices for Merkle tree values.
  (#846)
• Use index-set to reduce serialized size of block results.
  (#859)

TESTING

• Allow size zero bonds in PoS for testing.
  (#813)

Namada 0.11.0

Namada 0.11.0 is a scheduled minor release.

BUG FIXES

• Fix building with the abcipp feature again
  (#754)
• Fixed validation of a validator initialization transaction.
  (#763)

FEATURES

• Allow to set the native token via genesis configuration.
  (#582)
• Added a validity predicate for implicit accounts. This is set in
  protocol parameters and may be changed via governance. Additionally,
  added automatic public key reveal in the client that use an implicit
  account that hasn't revealed its PK yet as a source. It's also
  possible to manually submit reveal transaction with client command
  (#592)
• PoS: Removed staking reward addresses in preparation of auto-staked rewards
  system. (#687)
• Allow to set validator's commission rates and a limit on change of commission
  rate per epoch. Commission rate can be changed via a transaction authorized
  by the validator, but the limit is immutable value, set when the validator's
  account is initialized. (#695)
• Optimize the PoS code to depend only on bonded stake, removing
  the VotingPower(Delta) structs. This mitigates some previous
  information loss in PoS calculations. Instead, the notion of
  voting power is only relevant when communicating with Tendermint.
  (#707)
• Update the set of parameters in the PoS system according to the
  latest spec and standardizes the use of the rust_decimal crate
  for parameters and calculations that require fractional numbers.
  (#708)
• Renamed transaction CLI arguments --fee-amount and --fee-token to --gas- amount and --gas-token. (#775)

IMPROVEMENTS

• Refactored token decimal formatting.
  (#436)
• Added PoS specific queries (#570)
• Added a custom events store and replaced WebSocket client for
  transaction results with query endpoints to the events store.
  (#674)
• Refactored governance code to use storage_api.
  (#719)
• Public parts of shared namada crate have been split up into a
  namada_core crate. The namada_proof_of_stake, namada_vp_prelude
  and namada_tx_prelude crates now depend on this namada_core crate.
  (#733)
• Sign over the hash of code rather than code in transaction signing.
  (#807)

MISCELLANEOUS

• Improve some docstrings relating to block heights
  (#650)

TESTING

• Don't fake a wasm VP for internal addresses in tx tests
  (#694)
