Documentation: the feature comparison in the plugin description is now laid out per plugin with clear status icons (✅ free / 🔒 Pro / ❌ not available), instead of a Markdown table that the WordPress.org plugin directory does not render. Added YaySMTP to the comparison. No functional changes.
1.3.2 – 21.05.2026
Fix: SMTP password is now stored correctly on the very first save. Previously, due to WordPress running the sanitize filter twice when an option does not yet exist (update_option → add_option), the password was AES-encrypted twice on first save, causing the test email and all subsequent sends to fail with an authentication error until the password was entered and saved a second time. Encryption is now idempotent — values already encrypted are no longer re-wrapped.
Note for existing users with a working SMTP password: no action required, your saved password keeps working.
Note for existing users still seeing auth errors after first save (the bug above): simply enter the password once more and save — the new release will store it correctly.
