[0.2.0] - 2026-03-18

Fixed

Critical: PageHeader.num_pages changed from u16 to u32 to support >256MB allocations
Added missing posix_memalign C ABI export (was causing heap corruption)

Added

Stress test suite: tail latency, massive allocations, corruption tests
GitHub Actions workflow with full benchmark suite
Weekly scheduled benchmark runs with GitHub Summary output

Performance

Tail latency P99: 116ns (comparable to glibc's 103ns)
Massive allocations: 2GB contiguous blocks with 2MB alignment supported
Corruption test: 100,000+ operations without heap corruption
