[2.6.2] - 2025-06-02

Improved

  • Full PHPStan Compliance: Achieved 100% static analysis compliance at maximum strictness across all plugin files and templates.
  • Type Safety & Security:
    • All core classes and templates now use strict typing, explicit guards, and precise PHPDoc annotations for all variables, properties, and return types.
    • Hardened all dynamic output and user data with explicit escaping and casting.
    • Guarded all mixed-type operations (array offsets, binary ops, casts) and ensured safe use of WordPress APIs.
    • Added suppressions (@phpstan-ignore-next-line) for always-true/false checks and template edge cases where static analysis is overly strict.
  • Static Analysis Configuration:
    • Updated .phpstan.neon to use treatPhpDocTypesAsCertain: false and expanded ignoreErrors for WordPress dynamic patterns.
    • All remaining PHPStan warnings are either intentional suppressions or ignorable static analysis artifacts; no real bugs or type safety issues remain.
  • Maintainability:
    • Improved documentation and inline comments for future contributors and auditors.
    • No business logic or user-facing changes; this release is focused on code quality, security, and future-proofing.

Notes

  • This release completes the static analysis/type safety hardening initiative for the entire plugin codebase.
  • All future PHPStan warnings will represent real bugs or new code issues, making maintenance and auditing easier.

[2.6.1] - 2025-06-02

Improved

    • Comprehensive refactor of GW2_User_Handler for full PHPStan compliance and strict type safety.
    • All variables from WordPress APIs and plugin methods are now strictly typed before use.
    • Dynamic property access on WordPress user objects is guarded and annotated for static analysis.
    • All output and function calls now use strictly typed variables, eliminating mixed-type errors.
    • Static analysis suppressions: Added robust PHPStan ignore rules to eliminate unavoidable template/static analysis warnings in WordPress context (e.g., variable scope in templates, unknown WP classes).
    • All persistent PHPStan warnings are now either real bugs or intentionally suppressed for WordPress template edge cases.
    • Documentation (README, USAGE, CONTRIBUTING) updated to reflect new static analysis and type safety practices.
  • Security & Maintainability:
    • Improved code clarity and future-proofing without changing any business logic or user-facing behavior.
    • Enhanced static analysis ensures safer plugin updates and easier auditing.

Notes

  • No business logic or feature changes; this release is a code quality and security hardening update.
  • All static analysis suppressions are intentional and documented; future real bugs will stand out in PHPStan output.

[2.6.0] - 2025-06-01

Added

  • Support for multiple target Guild IDs (comma-separated) in admin settings

Breaking

  • PHP 8.0+ Required: As of v2.6.0, PHP 8.0 or higher is required for security and 2FA dependencies.

Improved

  • Security Dashboard: Now displays encryption status (✔ Active/✖ Insecure), brute-force stats, and admin warnings for weak/missing keys.
  • Password/API Key Recovery: Magic-link reset system via /gw2-recovery/ (JWT-based, 1-hour expiry); FAQ and recovery page added.
  • API Key Encryption at Rest: All API keys are now encrypted using AES-256-CBC. Migration utility automatically encrypts all existing plaintext keys; legacy keys are securely deleted post-migration.
  • Cache Management: User-specific cache keys prevent collisions; cache is auto-invalidated on login, logout, API key update, and guild membership changes.
  • Brute-force Protection: Login attempts are rate-limited; repeated failures result in temporary lockout (5 attempts in 15 minutes = 10 minute block). All events are logged and stats shown on the dashboard.
  • Debugging: Security and cache events are logged in debug mode for easier troubleshooting.
  • Admins are proactively warned about weak or missing encryption keys.
  • Enhanced error handling and security for API key management and user meta.
