v1.17.0

Featured Changes

• New StdSecp256k1 library: curve constants, affine and projective identities, scalar validation, parity encodings, and Ethereum address derivation. Includes dedicated unit and fuzz coverage. (#912, #923)
• Expanded cheatcode interface: elliptic-curve operations, slot-number access, eth_getProof, and additional JSON and FFI helpers.
• More reliable stdStorage: discover short string/bytes slots, handle signed fields narrower than 256 bits, and stop access recording after discovery. (#894, #904, #906)
• Config-only chains: load chain configuration without an RPC endpoint; an endpoint is required only when requested. (#903)
• State-gas reporting: Vm.Gas now includes gasStateUsed, with documentation explaining execution gas, state gas, and refunds. (#907)

Compatibility: Vm.Gas gains a field, so explicit struct initializers need updating. Older Foundry versions returning the previous tuple layout may fail decoding; use Foundry v1.8.3 or newer.
