# Changelog

> Fuego Suite Updates & Features

<CodeGroup>
  ```text Changelog theme={null}
  v1.11.01 (Hearth call-auction orderbook — v11)
  * Per-block call auction: user-vs-user crossing at a max-volume clearing price (price discovery); tx-extra-backed deposits; AMM is a volume-capped backstop (`HEARTH_BACKSTOP_MAX_BPS`).
  * Fee model: 1% taker fee split 70% CD yield / 30% maker rebate (auction makers; LPs on pool fills). Min price tick (`ORDER_PRICE_TICK`).
  * All v12-gated consensus work re-gated to v11 (chain height at decision: 1,015,027 < 1,111,111).

  v1.11.00 (Consensus v12 — Hearth orderbook rework, treasury, CD economics)
  * **Hearth orderbook**: in-band CLOB matcher + gossiped orders retired. Limit orders are now tx-extra-backed (`TransactionExtraLimitDeposit`) deposits executed at block time against the pool at the live spot price; height-based expiry; partial fills with claimable proceeds (`TransactionExtraLimitWithdraw`).
  * **Canonical price scale**: HEAT/XFG × COIN (1e7) everywhere — mint, swaps, quotes, TWAP; Q64.64/1e8/1e18 purged from price paths (legacy preserved for pre-v12 re-validation).
  * **LP**: balanced deposits only (single-sided mints nothing); fair pro-rata shares; LP income = pool trading P&L, not the flat fee.
  * **Fees**: taker pays the 1% Hearth fee via fee-adjusted output; fee debited from LP reserves → HEAT-denominated `cdHearthFeeAccumulator` → `CD_APY_POOL` at epoch; consumed XFG burned 50/50 (EF/SWF). `/addswapfee` authenticated; swap fees accounted exactly (2% claim / 1% refund).
  * **Treasury**: Treasury LP Manager provisions the protocol's ratio-paired LP position (20% treasury share + mint premiums + HEAT CD fees + donations via the `TreasuryFund` tag); bonus vault (11%) converts to HEAT; bootstrap repayment = two-leg owned-reserves check; overall burn tally (`total_burned_xfg`).
  * **CD economics**: HEAT-denominated epoch rates, CD-only APY denominator, block-level interest cap, youngest-ring interest cap, consensus term whitelist, legacy XFG deposits withdraw-only at v12.
  * Security fixes: AMM swap settlement from actual balance deltas, coinbase settlement-tag rejection, orderbook UAF, mainnet fee-pool funding, epoch snapshot at block start.

  v1.10.04 (Docs + consensus)
  * Hearth flat fee routing corrected: 1% → **100% CD yield** (`cdHearthFeeAccumulator`); LPs earn the swap spread, not the fee. Removed 50/50 CD/LP split from consensus code + docs.
  v1.10.03 (Docs)
  * Public Mintlify docs rewritten for current product: HEAT mint → HEAT CDs,
    Hearth (1% fee 100% CD yield; LPs earn the spread), swapXFG (1% fee 69/11/20), dual-asset architecture.
  * Removed primary nav for STARK-only heat-burns and core DIGM onboarding weight.
  * Docs CI: `.github/workflows/docs.yml` (alignment tests + mint validate/broken-links).
  * Single changelog source: `docs/changelog.mdx` only.
  * Strategy marketing fee copy aligned to live CryptoNoteConfig.h constants.

  v1.10.02 (Current)
  * AFK atomic swaps: soft-order auto-execution engine (OfferManager), griefing
    protection with taker rate-limiting, partial fills, price-drift auto-cancel,
    headless daemon mode with StatusServer monitoring endpoint.
  * Cross-chain timelock-ordering safety via SwapTimelock (SOL/ETH/XMR/BCH/ARB/BASE).
  * ETH EIP-155 offline signing (secp256k1); adaptor-secret at-rest persistence
    with CryptoNight-KDF + ChaCha8 + HMAC-SHA256.
  * Ed25519 P2P message authentication for all swap peer messages.
  * Wallet integrity upgraded to HMAC-SHA256 (v7); file permissions set to 0600.
  * RPC error responses sanitized (no internal details exposed to clients).
  * Alias registration privacy: per-tx sub-address rotation, ring-sig mixin.
  * Small-subgroup point rejection in adaptor/DLEQ verifiers.
  * RNG fork safety (pthread_atfork reseed); modulo-bias elimination.
  * Taker P2P swap-request relay; cancel-command fix.
  * Arbitrum and Base L2 chain support (EVM adaptor swaps).
  * SwapP2P hardened: default loopback bind, worker cap, bounded message queue.
  * PriceOracle bootstrap drift guard (±50% from seed rate).

  v1.10.01
  * Clean up repo for release.
  * Fix stream tools endianness conversion for integers.

  v1.9.3
  * Intent-based soft orders for AFK atomic swaps.
  * Implement AFK Adaptor Swaps: Taker flow, monitoring view, and refund mechanism.
  * TUI Updates.
  * ZK prover for HEAT merkle.
  * Elderfier broadcast fix to keep merkle as source of truth not p2pmsg.
  * Update Boost dependency to 1.86+ (migrated to `io_context`, `executor_work_guard`).
  * OpenSSL 4.x support.
  * secp256k1 external dependency support (system package or submodule).
  * RPC Server Modernization.
  * Implement CD banking fee burn and SwapDaemon CD support.

  v1.9.2
  * Add subaddresses support to core and simplewallet.
  * Initialize Fuego Flutter Wallet project.
  * Add Elderfier CLI menu system.
  * Digm coin branch integration.

  v1.9.1
  * Add comprehensive walletd build workflow.
  * Update difficulty calculation adjustments.

  v1.9.0
  * Add comprehensive simplewallet functionality for checking CDs, Burns, and Aliases.
  * Dandelion++ support (Upgrade Height v10).
  * (FuegoMeshtastic and FuegoI2P components exist but are in integration phases, see codebase).

> **Privacy Note:** Fuego relies on Ring Signatures and stealth addresses to provide privacy by hiding the sender, receiver, and breaking transaction linkage. Fuego uses per-amount decoy selection, and HEAT burns provide permanent decoys that bulk up the ring pool. Amounts transferred are currently visible on-chain. Deposit types are also visible (HEAT=0x08, CD=0xCD, YIELD=0x07) unless obscured.
