## Release Notes
Klaytn v1.10.2 contains a hardfork upgrade that results in backward-incompatible changes. All Baobab/Cypress nodes would thus have to be upgraded to v1.10.2 or higher before the target block number. The hardfork implements \[[KIP-103](https://kips.klaytn.foundation/KIPs/kip-103)] that is a technical specification of \[[KGP-6](https://govforum.klaytn.foundation/t/kgp-6-proposal-to-establish-a-sustainable-and-verifiable-klay-token-economy/157)].
The hardfork schedule is as follows:
**Baobab Testnet**
* BlockNumber: 119145600 (estimated time: 6 Apr, 4:20 AM UTC+9)
* Hardfork contents: KIP-103 hardfork (Baobab already applied Kore hardfork)
* TreasuryRebalance contract address: 0xD5ad6D61Dd87EdabE2332607C328f5cc96aeCB95
**Cypress Mainnet**
* BlockNumber: 119750400 (estimated time: 17 Apr, 01:01 AM UTC+9)
* Hardfork contents: Kore, KIP-103 hardforks
* TreasuryRebalance contract address: 0xD5ad6D61Dd87EdabE2332607C328f5cc96aeCB95
\*You can find detailed information on TreasuryRebalance contract from [KIP-103](https://kips.klaytn.foundation/KIPs/kip-103)
NOTE: At the activation of [KIP-103](https://github.com/klaytn/kips/pull/104), the balance of the Treasury account will be changed in an unusual way. You can find the change result on the TreasuryRebalance contract. NOTE: Some APIs (`governance_getStakingInfo`, `klay_getStakingInfo`, `governance_getRewards`) change their returning field names of `KGF`, `KIR` to `kff`, `kcf` respectively. The old field names will remain before v1.11.0 for backward compatibility.
### Hardfork features
* [KIP-103](https://kips.klaytn.foundation/KIPs/kip-103): Implementing TreasuryRebalance (#1803 #1809 #1810)
### Improvements
* Extended the maximum transaction size to 128KB (#1733)
* Enhanced voting input validation of governance system (#1767)
* Unified the activation timing of governance items to the epoch block number (#1772)
* Introduced new APIs reading chain configurations and governance parameters (#1783)
* new APIs: `governance_getParams`, `governance_getChainConfig`, `klay_getParams`, `klay_getChainConfig`
* Introduced timeout trigger on debug tracing APIs (#1762)
* Introduced new admin APIs syncing stakingInfo with other peers (#1778)
* `admin_syncStakingInfo` and `admin_syncStakingInfoStatus`
* Changed returning field names from `kgf/kir` to `kff/kcf`(#1789 #1792)
* `kgf` -> `kff`, `kir` -> `kcf`, `KGFAddr`-> `kffAddr`, `KIRAddr` -> `kcfAddr`
* affected APIs: `governance_getStakingInfo`, `klay_getStakingInfo`, `governance_getRewards`
* APIs returns old field name as well before v1.11.0 for backward compatibility
* Enables `http` as default RPC server configuration deprecating `fasthttp` (#1786)
* If a node configures `fasthttp`, it will be updated to `http` automatically
### Fixes
* Fixed `governance_paramsAt` API to read a more proper block number (#1779 #1791)
* Fixed consensus bugs that can be a problem when committeeSize is equal to or less than 3 (#1787)
* Fixed unexpected node loading failure after unexpected node termination (#1766)
* Fixed `klay_getRewards` API to exclude the remainder in the calculation (#1771)
### Miscellaneous
* Minor maintenance (#1747 #1757 #1748 #1764 #1675 #1768 #1769 #1782 #1785 #1812)
