| **v2.0** | **✅** | **VaptVupt 1.1.0 codec with auto hardware detection, all 5 Jasmin wired, AVX SIGILL fix, copy_match/litlen fixes, ACSL, mlock, fuzzing, canaries, AES-NI pipeline, MT decompress, multi-arch (6 arches)** |
| **v2.1** | **✅** | **VaptVupt 1.4.0: cross-block dictionary, context prefetch, faster adaptive window, integration API** |
| **v2.1.1** | **✅** | **Termux/Android build fix, arch-safety guard, Keccak UB fix, no stale .o in tarballs** |
| **v2.1.2** | **✅** | **Full-disk backup/restore with sparse detection, all encryption modes, progress bar, 77 tests** |
| **v2.1.3** | **✅** | **Disk restore rewritten — shared block I/O, fixes checksum mismatch on encrypted/PQ archives** |
| **v2.1.3** | **✅** | **LZHP prediction encoding fix, shared write_enc_header, SOLID flag removed from disk, 78 tests** |
| **v2.1.4** | **✅** | **CodeQL: 4 security fixes — TOCTOU races (fstat on fd), X25519 scalar wipe (volatile), 78 tests** |
| **v2.1.5** | **✅ Current** | **Block-level deduplication (--dedup), XXH64 fingerprint index, DEDUP_REF block type, 81 tests** |

## Planned

| Version | Status | Description |
|---------|--------|-------------|
| v2.1 | 📋 Planned | Homebrew, AUR, Debian, RPM, Nix packages |
| v2.2 | 📋 Planned | Coverity Scan, clang-tidy security checkers, Frama-C Eva analysis |
| v2.3 | 📋 Planned | Silesia corpus benchmarks, performance tuning, NEON ARM64 decode path |
| v3.0 | 🔮 Future | EasyCrypt machine-verified proofs for Jasmin crypto, independent audit |

## Priority Order

```
v1.6  AES-NI wired in          ← closes #1 security gap (table-based AES)
v1.7  X25519 Jasmin wired in   ← all 4 Jasmin functions active
v1.8  ACSL + Frama-C           ← formal memory safety proofs
v1.9  mlock + fuzzing           ← closes remaining hardening gaps
v2.0  Performance               ← 4× AES throughput, parallel decompression
```

## Security Gap Status

| Gap | Severity | Status |
|-----|----------|--------|
| Table-based AES (cache-timing) | High | **✅ Closed v2.0** — AES-NI Jasmin |
| X25519 fe_cswap CT | Low | **✅ Closed v2.0** — Jasmin |
| No mlock() for keys | Medium | **✅ Closed v2.0** |
| No fuzzing | Medium | **✅ Closed v2.0** — AFL++ |
| ACSL unproved | Low | **✅ Closed v2.0** — 19 contracts |
| No independent audit | Medium | Open — target v3.0 |
