 # Changelog

-Post 1.0.0 release, the changelog format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [Unreleased]
-
-### Added
-
- all: added network compilation target to `--help` (or `--version`) commands ([#1256]).
- explorer-api: learned how to sum the delegations by owner in a new endpoint.
- gateway: Added gateway coconut verifications and validator-api communication for double spending protection ([#1261])
- mixnet-contract: Added ClaimOperatorReward and ClaimDelegatorReward messages ([#1292])
- mixnet-contract: Replace all naked `-` with `saturating_sub`.
- network-requester: send traffic statistics from all network requesters and receive it in a special network-requester that aggregates the data and exposes it via a rest API ([#1267], [#1278]).
- validator-api: add `estimated_node_profit` and `estimated_operator_cost` to `reward-estimate` endpoint ([#1284])
- validator-api: add detailed mixnode bond endpoints, and explorer-api makes use of that data to append stake saturation.
- validator-api: add Swagger to document the REST API ([#1249]).
- validator-api: Added new endpoints for coconut spending flow and communications with coconut & multisig contracts ([#1261])
- vesting-contract: Added ClaimOperatorReward and ClaimDelegatorReward messages ([#1292])
- wallet: add simple CLI tool for decrypting and recovering the wallet file.
- wallet: added support for multiple accounts ([#1265])
- wallet: compound and claim reward endpoints for operators and delegators ([#1302])
- wallet: require password to switch accounts
- wallet: the wallet backend learned how to keep track of validator name, either hardcoded or by querying the status endpoint.
-
-### 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])
- mixnode, gateway: attempting to determine reconnection backoff to persistently failing mixnode could result in a crash ([#1260])
- mixnode: the mixnode learned how to shutdown gracefully.
- vesting-contract: replaced `checked_sub` with `saturating_sub` to fix the underflow in `get_vesting_tokens` ([#1275])
- native & socks5 clients: fail early when clients try to re-init with a different gateway, which is not supported yet ([#1322])
-
-### Changed
-
- validator-client: created internal `Coin` type that replaces coins from `cosmrs` and `cosmwasm` for API entrypoints [[#1295]]
- all: updated all `cosmwasm`-related dependencies to `1.0.0` and `cw-storage-plus` to `0.13.4` [[#1318]]
