Release v2.2.0

Fixed

• Correct native CI notice assertions, multisite bootstrap timing and post-by-email filter expectations.
• Use system executable paths in automation helpers and add regression checks for executable substitution through PATH.
• Document three resource-hint URL false positives for Plugin Check with line-specific exceptions; resource-hint behavior is unchanged.
• Correct optimizer packaging and isolate unit/native CI discovery, retaining the existing quality gates and dependency lanes.
• Limit domain-list work and retain previous values for oversize submissions; skip oversize saved lists without changing their stored text.
• Report rejected-line totals with at most three safe samples and avoid duplicate plugin warnings during repeated validation.
• Build exact resource-hint membership once per callback, preserving foreign entries without unsafe value conversions.
• Reject unsupported preconnect ports and skip legacy custom-port hints while preserving their saved text until an explicit save.
• Correct admin and embed emoji hooks, safely match equivalent DNS hint hosts, and apply reversible filters using the current site's settings.
• Use the core settings notice display, escape plain-text section and field titles, and associate textarea instructions with their controls.
• Read current-site options through WordPress caching and retain virtual defaults until a changed save.
• Preserve previous domain lists for malformed submissions and validate original URL text before normalization.
• Omit submitted URLs and credentials from localized rejection messages, with safe line-specific feedback.
• Remove the plugin option across multisite networks during uninstall, verify physical row deletion, restore site context, and stop file removal when cleanup fails.

Changed

• Split package validation and automation tests into focused functions while retaining all invalid-package cases.
• Align the WordPress Tested up to metadata at 7.1.
• Document per-site settings, domain-list limits and uninstall requirements; align contributor guidance and quality-check claims with the repository.
• Clarify settings help and Jetpack promotion labels without changing feature behavior or validation rules.
• Refresh the translation template from all production PHP, including uninstall messages, and declare the bundled language directory.
• Explain domain-list byte and line limits and show associated guidance for oversize saved lists.
• Retire the obsolete Windows Live Writer manifest setting; ignore its old key on reads and omit it on a normal save.
• Clarify HTTPS port requirements, hostname-only DNS prefetch behavior, and invalid-list save behavior in settings help.
• Restore optimizer package, analyzer and contributor-guidance targets while preserving locked dependency versions.
• Code Quality: Replaced PHP-native IP validation with WordPress native IP validation for resource hint host checks
