// need to detect <1.8, this is a simple check that should suffice. Checking
// for "1.7." would be a bit safer, but the version string is 1.7, not 1.7.0
// and we'll never reach 1.70.0 (if we do, we certainly won't be supporting
// 1.7 anymore). See #11197 for why we're not using feature detection.
