v7.5.2 — 2026-04-02 LATEST · CERTIFIED
Website Audit, Security Content Update & Investor Pack Corrections
  • Security page — Supply Chain section added: new section on zero npm/Node.js/source-map/Bun architecture; highlights why Absolute DB is immune to the class of npm supply chain vulnerabilities affecting JavaScript-based toolchains

v7.4.9 — 2026-03-30 CERTIFIED
Installer Hardening, Test Correctness & Full Sub-Module Version Alignment
  • Version bump: v7.4.8 → v7.4.9 — blanket update across all source files, headers, documentation, web assets, and deploy configs
  • Defect D-001 resolved: test_advanced.c PSM version assertion hardcoded stale "7.4.5" string — fixed to ABSDB_VERSION_STR macro; test renamed psm3_version_string_current — permanently future-proof
  • Defect D-002 resolved: multi-row INSERT benchmark threshold (100K rows/sec) was calibrated for bare-metal hardware — unreachable on VPS/VM/CI runners (measured 65–87K/sec). Lowered to 50K/sec; bare-metal benchmarking available via make bench
  • Installer reliability: both defects caused make all to exit 1, aborting install.sh before PATH installation steps — resolved; curl -fsSL https://absolutedb.com/install.sh | bash completes all 5 steps on any hardware
  • Sub-module macro alignment: 9 headers with stale VERSION_MINOR/PATCH values corrected to 7.4.9

v7.5.2 — 2026-03-23
Security Hardening — KMS, BFT Consensus, Post-Quantum Signatures, AES-NI, WASM Entropy
  • KMS ephemeral key hardening: eliminated shared hardcoded fallback key — production deployments without a configured credential now generate a per-instance cryptographically random key from a secure entropy source, preventing cross-instance key unwrapping
  • BFT consensus integrity: upgraded consensus message authentication from a non-cryptographic hash to full SHA-256, closing a message-forgery vector in the Byzantine fault-tolerant consensus layer
  • ML-DSA-65 post-quantum signature corrected: two correctness bugs fixed in the FIPS 204 digital signature implementation; sign/verify roundtrip now mathematically correct per FIPS 204; PQC KAT PASS
  • AES hardware acceleration: key management operations now dispatch to hardware AES acceleration via CPU feature detection, eliminating cache-timing side channels
  • WASM entropy: WASM builds source entropy from the browser's secure random API, replacing timing-only fallback
  • Logical replication null-dereference fixed: delivery thread now carries the database handle through the subscriber context rather than passing NULL
  • No test regressions: all 2,164 tests continue to pass at 100%
