19-
- **Breaking:** Add a new state variable `jumpDisputeKitID` to the `DisputeKitClassicBase` contract ([#2114](https://github.com/kleros/kleros-v2/issues/2114))
2018
- Make `IDisputeKit.draw()` and `ISortitionModule.draw()` return the court ID from which the juror was drawn ([#2107](https://github.com/kleros/kleros-v2/issues/2107))
2119
- Rename `SortitionModule.setJurorInactive()` to `SortitionModule.forcedUnstakeAllCourts()` ([#2107](https://github.com/kleros/kleros-v2/issues/2107))
22-
- Allow stake changes to by-pass delayed stakes when initiated by the SortitionModule by setting the `_noDelay` parameter to `true` in `SortitionModule.validateStake()` ([#2107](https://github.com/kleros/kleros-v2/issues/2107))
2320
- Make the primary VRF-based RNG fall back to `BlockhashRNG` if the VRF request is not fulfilled within a timeout ([#2054](https://github.com/kleros/kleros-v2/issues/2054))
2421
- Authenticate the calls to the RNGs to prevent 3rd parties from depleting the Chainlink VRF subscription funds ([#2054](https://github.com/kleros/kleros-v2/issues/2054))
2522
- Use `block.timestamp` rather than `block.number` for `BlockhashRNG` for better reliability on Arbitrum as block production is sporadic depending on network conditions. ([#2054](https://github.com/kleros/kleros-v2/issues/2054))
2623
- Replace the `bytes32 _key` parameter in `SortitionTrees.createTree()` and `SortitionTrees.draw()` by `uint96 courtID` ([#2113](https://github.com/kleros/kleros-v2/issues/2113))
