| 2 | + |
| 3 | +### Features: |
| 4 | + |
| 5 | +**WalletConnect Integration**: |
| 6 | +- WalletConnect v2 support for EVM and Cosmos coins was implemented, enabling wallet connection and transaction signing via the WalletConnect protocol. [#2223](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2223) [#2485](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2485) |

| 8 | +--- |
| 9 | + |
| 10 | +### Work in Progress (WIP) Features: |
| 11 | + |
| 12 | +**Cosmos Network and IBC Swaps**: |
| 13 | +- Pre-swap validation logic was implemented for maker order creation, requiring HTLC assets and healthy IBC channels on the Cosmos network, with all changes gated behind the `ibc-routing-for-swaps` feature. [#2459](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2459) |
| 14 | +- The taker and maker order types were extended with an `order_metadata` field to carry protocol/IBC details, and cross-checks for IBC channels were added (also feature-gated), enabling both parties to validate IBC routing before a swap. [#2476](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2476) |
| 15 | + |
| 16 | +**TRON Integration**: |
| 17 | +- Initial groundwork for TRON integration was started, including the addition of basic structures and boilerplate code; no end-to-end functionality is yet available. [#2425](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2425) |
| 18 | + |
| 19 | +--- |
| 20 | + |
| 21 | +### Enhancements/Fixes: |
| 22 | + |

| 28 | + |
| 29 | +**Orders and Trading Protocol**: |
| 30 | +- The minimum trading volume logic was revised to remove BTC-specific volume behavior, standardizing the calculation across all coins. [#2483](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2483) |
| 31 | + |
| 32 | +**Tendermint / Cosmos**: |

| 42 | +- Transaction fee calculation and minimum relay fee handling for UTXO coins were improved for accurate fee estimation. [#2316](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2316) |
| 43 | + |
| 44 | +**EVM / ERC20**: |
| 45 | +- ETH address serialization in event streaming was updated to use the `AddrToString` trait for consistency. [#2440](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2440) |
| 46 | + |
| 47 | +**Pubkey Banning**: |
| 48 | +- Expirable bans for pubkeys were introduced, allowing temporary exclusion of certain public keys. [#2455](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2455) |
| 49 | + |
| 50 | +**RPC Interface**: |
| 51 | +- A unified interface was implemented for legacy and current RPC methods. [#2450](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2450) |

| 58 | + |
| 59 | +**Build and Dependency Management**: |

| 81 | +### NB - Backwards compatibility breaking changes: |
| 82 | + |
| 83 | +**WalletConnect/EVM Coin Activation Policy**: |
| 84 | +- The `priv_key_policy` field for EVM coin activation now requires the new enum variant format: `"priv_key_policy": { "type": "ContextPrivKey" }`. [#2223](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2223) |
| 85 | + |
| 86 | +**TRON/EVM Chain Specification**: |
| 87 | +- EVM coin configurations must now include `chain_id` inside the `protocol_data` field. Legacy `chain_id` fields are deprecated. [#2425](https://github.com/KomodoPlatform/komodo-defi-framework/pull/2425) |
| 88 | + |
