v0.4.2

Bug Fix

• Fix language switcher getting stuck when navigating back/forth between languages. The browser's back-forward cache (bfcache) was restoring pages with the loading state still applied, blocking further clicks.

v0.4.1

Instant Language Switching

• Prefetch: Pre-fetches the alternate language page in the background so it's ready before the user clicks
• Prerender (Chrome 109+): Uses the Speculation Rules API to fully pre-render the alternate page in a hidden tab — navigation is truly instant
• Loading state: Immediate visual feedback (opacity + cursor change) when clicking the switcher

Page-Level Translation Cache

• Caches the fully processed translated HTML output in transients
• On cache hit, skips ALL regex processing (URL rewriting + translation replacement)
• Automatically excludes: logged-in users, WooCommerce cart/checkout/account pages, debug mode
• Cache invalidation is automatic when translations are edited

v0.4.0

Performance Optimizations

• Wrap all error_log() calls with WP_DEBUG guard (eliminates disk I/O in production)
• Conditionalize microtime() timing behind WP_DEBUG
• Combine two URL rewrite regex passes into a single pattern (fewer HTML traversals)
• Add static cache to gt_get_switcher_style() (avoids repeated get_option() calls)
• Fix gt_invalidate_translation_cache() to properly reset static cache
• Move GitHub Updater to admin/cron only (skip frontend requests)

Features

• Batch Gemini API translation (multiple strings per request, batch size 25)
• Add composite DB index (language_code, status) for faster queries
• Extract HTML button/option text from Elementor HTML widgets
