SIM — Retail Edition Changelog

v0.1.0 — Jul 20 – Aug 7, 2026

A single fast-moving pre-1.0 release line — SIM Retail went from fork to functioning multi-branch POS in about two and a half weeks. Grouped below by what landed in each phase.

Polish (Aug 7, 2026)

• Masked PIN inputs with a show/hide toggle
• POS navigation now uses the synced branding logo instead of a bundled asset
• Moved the set-PIN route so auth tokens attach correctly
• Fixed a false-positive POS/server version-mismatch warning in server discovery

Stability (Aug 1, 2026)

• Fixed POS fresh-install crashes, including a native module compile issue affecting receipt printing
• Correctly stamped build version in the backend
• Full user-management UI: create, delete, and PIN-reset for the seeded admin account
• Update detection now flags any SHA difference from the latest release, instead of relying on version-string comparison
• Fixed the auto-updater's repo slug, left over from the original fork
• Log viewer gated to the Admin role instead of a hardcoded username
• Added a built-in support login for remote troubleshooting

Feature build-out (Jul 21–31, 2026)

• Dev/master login flow and an offline user cache so the POS can authenticate without a live connection
• White-label branding: server discovery, branded POS login screen, configurable app identity
• User registration and role-based route guards
• Per-branch sales and stock tracking
• Rebranded from the SIM gym codebase to SIM Retail

Hardening (Jul 21, 2026)

• Fixed an unauthenticated password-reset endpoint that allowed account takeover
• Fixed unauthenticated file upload/serve endpoints
• Fixed password hashes leaking through several API responses (/api/users, /api/auth/me, POS sync)
• Added class-validator DTOs across every backend module
• Added a ~790-test Jest suite covering 9 modules, plus a CI workflow to run it
• Fixed a commission-math bug where refunds weren't netted correctly

Initial build (Jul 20, 2026)

• Forked from SIM: gym-specific modules (members, NFC check-in, subscriptions, personnel attendance) stripped out
• New retail modules scaffolded: purchasing, suppliers, customers/loyalty, multi-branch, cashflow
• White-label branding groundwork and back-office admin pages
