⚠️ Breaking Changes ⚠️

• MODEXP calls with base, exponent, or modulus > 1024 bytes will now fail and consume all gas (#3638)
• Transactions with gas limit > 16,777,216 will be rejected at validation (#3638)
• EIP-7883 greatly increases ModExp gas costs, which can lead to smart contract failures. (#3632)
• Many XCM instructions weight increased (#3624)
• Transaction fees may increase for Substrate extrinsics whose weight is dominated by proof_size rather than ref_time. This particularly affects storage-heavy operations. (#3571)
• pallet-xcm-transactor extrinsics setFeePerSecond and removeFeePerSecond are removed. (#3569)
• The DestinationAssetFeePerSecond storage map in pallet-xcm-transactor is removed. (#3569)

Changes

• Improve WeightToFee calculation (#3571)
• [MOON-3323] Refactor XCM Transactor to Delegate Fee Pricing to XCM Weight Trader (#3569)
• Improve multi-delegations requests handling (#3619)
• fix dest_asset_fee_per_second behavior (#3618)
• Add support for Osaka fork (EIP-7939) (#3628)
• Add support for EIP-7883 (#3632)
• Benchmark XCM instructions from polkadot-sdk pallet_xcm_benchmarks (#3624)
• Add support for EIP-7823 and EIP-7825 (#3638)
• Improve get_units_per_second computation (#3648)
• Add handling of MultipleLogs error in pallet-ethereum hooks (#3650)
• update frontier pin (#3654)
• Fix: Preserve beneficiary junction order in split_location_into_chain_part_and_beneficiary (#3649)
• Re-enable UniversalOrigin XCm instruction (#3659)
• Fix benchmarks and XCM refund logic (#3660)

Moonbeam v0.50.0

This client includes a Frontier Database Migration, so the steps to upgrade to v0.50.0 without issues are:

1. Stop your node
2. Purge your Frontier Database
3. Upgrade the binary/Docker image
4. Start the node

The Frontier database will be reconstructed automatically from the latest block to genesis.

Here you can find how to purge your Frontier Database:

• Docker - https://docs.moonbeam.network/node-operators/networks/run-a-node/docker/
• Binary - https://docs.moonbeam.network/node-operators/networks/run-a-node/systemd/

⚠️ Breaking Changes ⚠️

• Replace --ethapi-trace-cache-duration by --ethapi-trace-cache-size (default: 104857600 bytes / 100MB) (#3616)
• The block range provided in trace_filter RPC is now bounded by default to 1024 blocks. This value can be overridden by passing --max-block-range <MAX_BLOCK_RANGE> when starting the client. (#3601)

Changes

• Use the selected backend worker (Libp2p vs Litep2p) (#3595)
• Check block range on trace_filter RPC (#3601)
• Log the embedded relay version being used (#3596)
• reuse ExportGenesisHead from cumulus_client_cli (#3607)
• Guarantee spec compliance of eth_subscribe's newHeads (#3597)
• Improve the caching mechanism for trace-filter RPC (#3616)
• Update bootnode peer ID (#3621)
• Integrate Frontier's fix for eth_getTransactionReceipt race condition (#3651)

Moonbeam v0.49.3

⚠️ Breaking Changes ⚠️

The default network backend has been changed back to libp2p, from a recent investigation on our side, litep2p performs poorly in stable2506.

We recommend collators to use the default network backend and not override it --network-backend argument.

Changes

• Improve the caching mechanism for trace-filter RPC (#3616)
• Update Alphanet bootnode PeerID (#3621)
