If you push transactions through your own VeChain node, thor v2.5.1 is worth reading. Published 09:04 UTC today, it removes the privileged local tier: transactions submitted via the API now face the same caps as ones arriving from peers, and the old no-expiry, trim-exempt behaviour sits behind a flag that ships off. Packers also get a 30M floor on the adaptive gas limit, ceiling unchanged at 40M. No fork is activated and $VET mainnet needs no resync — historical results are identical.
