 ### Added

- nym-connect: initial proof-of-concept of a UI around the socks5 client was 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`.
- mixnet-contrat: Added staking_supply field to ContractStateParams.
- network-explorer-ui: Upgrade to React Router 6
- rewarding: replace circulating supply with staking supply in reward calculations ([#1324])
 - 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.
 - network-statistics: a new mixnet service that aggregates and exposes anonymized data about mixnet services ([#1328])

 - 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])
- validator: fixed local docker-compose setup to work on Apple M1 ([#1329])
