Changes for version 3.1801 - 2026-06-12
- Fixed undefined behavior in HCSR04.xs _setup(): RPI_PIN_MODE was re-stamped with putenv() of a stack buffer, leaving environ pointing at a dead frame after return; now uses setenv(), which copies its arguments
- The test suite board gate is now RPI_BOARD (ecosystem-wide rename from PI_BOARD); the old name is no longer honored
