Changelog

All notable changes to this project will be documented in this file.

[0.3.4]

Backend token verification module (lib/verifyToken.js) for server-side CAPTCHA validation
Support for verifying tokens with Cloudflare Turnstile, reCAPTCHA v2, and reCAPTCHA v3 providers
Comprehensive backend setup guide (BACKEND-SETUP.md) with integration examples for Budibase
Security warning in README emphasizing the requirement for backend token verification
Automatic execution support for Cloudflare Turnstile in invisible mode (component will call turnstile.execute on form submit)
Test harness and integration runner (test/run-tests.js, test/integration-run.js) plus npm scripts (npm test, npm run test:integration) for automated and live-provider testing

IMPORTANT: Documented that frontend validation is insufficient; backend verification is required to prevent form submission bypass attacks

Show the Action setting only when Provider Name is set to reCAPTCHA v3.
Clarified README documentation so Action is explicitly described as a reCAPTCHA v3-only setting.
