0.33.2

Improvements

Tendermint

• Upgrade Tendermint to v0.31.0-dev0-fix0 which includes critical security fixes.

0.33.1

Bug Fixes

Gaia

• #3999 Fix distribution delegation for zero height export bug

0.33.0

BREAKING CHANGES

• Gaia REST API

  • #3641 Remove the ability to use a Keybase from the REST API client:
    • password and generate_only have been removed from the base_req object
    • All txs that used to sign or use the Keybase now only generate the tx
    • keys routes completely removed
  • #3692 Update tx encoding and broadcasting endpoints:
    • Remove duplicate broadcasting endpoints in favor of POST @ /txs
      • The Tx field now accepts a StdTx and not raw tx bytes
    • Move encoding endpoint to /txs/encode

• Gaia

  • #3787 Fork the x/bank module into the Gaia application with only a
    modified message handler, where the modified message handler behaves the same as
    the standard x/bank message handler except for MsgMultiSend that must burn
    exactly 9 atoms and transfer 1 atom, and MsgSend is disabled.
  • #3789 Update validator creation flow:
    • Remove NewMsgCreateValidatorOnBehalfOf and corresponding business logic
    • Ensure the validator address equals the delegator address during
      MsgCreateValidator#ValidateBasic

• SDK

  • #3750 Track outstanding rewards per-validator instead of globally,
    and fix the main simulation issue, which was that slashes of
    re-delegations to a validator were not correctly accounted for
    in fee distribution when the redelegation in question had itself
    been slashed (from a fault committed by a different validator)
    in the same BeginBlock. Outstanding rewards are now available
    on a per-validator basis in REST.
  • #3669 Ensure consistency in message naming, codec registration, and JSON
    tags.
  • #3788 Change order of operations for greater accuracy when calculating delegation share token value
  • #3788 DecCoins.Cap -> DecCoins.Intersect

    CLI flag.

    • gaiacli keys show -o json now includes constituent pubkeys, respective weights and threshold
    • gaiacli keys show --show-multisig now displays constituent pubkeys, respective weights and threshold
    • gaiacli tx sign --validate-signatures now displays multisig signers with their respective weights
  • #3730 Improve workflow for
    gaiad gentx with offline public keys, by outputting stdtx file that needs to be signed.
  • #3761 Querying account related information using custom querier in auth module

• SDK

  • #3753 Remove no-longer-used governance penalty parameter

    where validator is unexpectedly slashed throwing off test calculations
  • #3411 Include the RequestInitChain.Time in the block header init during
    InitChain.
  • #3717 Update the vesting specification and implementation to cap deduction from
    DelegatedVesting by at most DelegatedVesting. This accounts for the case where
    the undelegation amount may exceed the original delegation amount due to
    truncation of undelegation tokens.
  • #3717 Ignore unknown proposers in allocating rewards for proposers, in case
    unbonding period was just 1 block and proposer was already deleted.
  • #3726 Cap(clip) reward to remaining coins in AllocateTokens.
