Moonbeam v0.50.4

⚠️ Do not use

Moonbeam v0.50.4 is not recommended for production.

This client release unfortunately introduced a regression for pruned nodes (--pruning N): eth_getBlockByNumber("latest") can return a permanently stuck block number while eth_blockNumber correctly tracks the chain tip. This affects load-balanced RPC endpoints where some backends appear "stuck" on old "latest" blocks.

Fix: Addressed in polkadot-evm/frontier#1856 — Improve "latest" block resolution on pruned nodes. A new Moonbeam client release that includes this fix is currently undergoing extensive testing, and will be released soon.

If you already run v0.50.4: Downgrate to the v0.50.3 release without a DB wipe or resync; "latest" starts advancing again within minutes after the downgrade.

Changes

• polkadot-evm/frontier#1832 — Avoid eth_blockNumber returning 0x00 when mapping-sync lags
• moonbeam-foundation/frontier#254 — Validate transaction size
  Adds RPC-level transaction size validation to eth_sendTransaction and eth_sendRawTransaction, rejecting transactions exceeding 128 KiB.
