Solana 🧭 Compass(@SolanaCompass):Solana V1 transactions are locally testable now — mainnet activation expected in a couple of weeks. Max transaction size: 1,232 bytes → 4,096 bytes (3.3×). Two breaking changes land the moment the first V1 tx hits mainnet: — RPC callers: add maxSupportedTransactionVersion: 1 to getTransaction/getBlock, or you get error -32015 on any block containing a V1 tx — Indexers: ComputeBudget scanning returns zero for V1; limits moved to transactionConfig Priority fees also change units: V0 uses micro-lamports per CU; V1 uses total lamports. SDK minimums: solana/kit 8.0.0, solana-* crates 4.2.x, solders 0.29.0. What are you planning to build with the extra headroom?
