-### Fixed
-
-- mixnet-contract: `estimated_delegator_reward` calculation ([#1284])
-- mixnet-contract: delegator and operator rewards use lambda and sigma instead of lambda_ticked and sigma_ticked ([#1284])
-- mixnet-contract: removed `expect` in `query_delegator_reward` and queries containing invalid proxy address should now return a more human-readable error ([#1257])
-- mixnet-contract: replaced integer division with fixed for performance calculations ([#1284])
-- mixnet-contract: Under certain circumstances nodes could not be unbonded ([#1255](https://github.com/nymtech/nym/issues/1255)) ([#1258])
-- mixnet-contract: Using correct staking supply when distributing rewards. ([#1373])
-- vesting-contract: replaced `checked_sub` with `saturating_sub` to fix the underflow in `get_vesting_tokens` ([#1275])
