v2.0.0

What's New

Major upgrade bringing full MailOdds API coverage to the WordPress plugin.

Suppression List Management

• Admin page under Tools > MailOdds Suppressions with search, filter, and pagination
• Add/remove entries via admin UI or WP-CLI
• Optional suppression pre-check on form submissions (saves API credits)
• Fail-open with admin notice when suppression API is unreachable

Bulk Validation Jobs API

• Smart routing: synchronous batch for under 100 users, async jobs for 100+
• Real-time progress polling with cancel and resume support
• Job history table
• Two-phase cron for shared hosting (no max_execution_time issues)

Validation Policies

• Admin page under Settings > MailOdds Policies
• Create custom policies or use presets (strict, permissive, smtp_required)
• Rule management (add/remove)
• Test policy sandbox
• Policy dropdown replaces the bare number input in settings

Telemetry Dashboard Widget

• Server-side telemetry from MailOdds API (24h and 30d windows)
• Credits used, deliverable/rejected/unknown rates, top rejection reasons
• Privacy safeguard: top domains never cached, widget can be disabled for GDPR/CCPA

WP REST API

• POST /wp-json/mailodds/v1/validate -- single email validation
• POST /wp-json/mailodds/v1/validate/batch -- batch up to 100 emails
• POST /wp-json/mailodds/v1/suppression/check -- suppression check
• GET /wp-json/mailodds/v1/status -- plugin health

Webhook Receiver

• POST /wp-json/mailodds/v1/webhook for job.completed events
• HMAC-SHA256 signature verification
• Closed by default (requires webhook secret in settings)

GitHub Auto-Updater

• Checks for new releases every 12 hours
• Graceful SSL error handling for shared hosts

API Client Improvements

• Generic request() method supporting GET, POST, PUT, DELETE
• 429 rate-limit handling with single retry (capped at 5 seconds)
• Transient cache flush when API key changes

WP-CLI

• 17 commands total (was 3): validate, bulk, status, plus suppression (5), jobs (5), and policies (4) subcommands

Tests

• 96 unit tests, 262 assertions
• New test suites: suppression, jobs, policies

Breaking Changes

None. All existing settings and user meta are preserved. The plugin is a drop-in upgrade from v1.x.
