+> applications, not just node operators:
+>
+> - `eth_call` / `eth_estimateGas` gas cap default lowered from 50M to 30M. Calls or
+>   simulations that previously relied on the higher cap will fail. Node operators can
+>   raise the limit with `--rpc.gascap`; DApps should optimize calls to stay within 30M.
+> - JSON-RPC batch requests are capped at 100 entries by default. Oversized batches are
+>   rejected with error `-32600` before any entry runs. Clients with JSON-RPC batching
+>   enabled should keep batch size at or under 100.
+> - Precompile gas accounting changed across v0.7.x (EIP-2929 warm/cold pricing on
+>   precompile account loads in v0.7.0, gas charging order in v0.7.2). Re-estimate gas
+>   against an updated node instead of reusing cached or hardcoded values.
