This is a stability patch that fixes a bug in the translation cache system affecting all file-cached translation providers. All users are recommended to upgrade for proper cache functionality.

🛠️ What's FIXED in Version 3.5.6

✅ Bug Fix

• 🔧 Translation Cache Duplicate Detection Bug Fixed: Resolved incorrect duplicate detection logic in the file cache system that was preventing translations of the same source text to different target languages from being saved
  • Before: The cache only checked if the source text was identical, ignoring the language pair
  • After: Now correctly checks both the source text AND the language pair (source→target) before treating an entry as a duplicate ✅
  • Impact: Ensures that translating the same source text to different target languages (e.g., English→French and English→Italian) are both properly saved to cache files
  • Affects: All translation providers that use file caching (Gemini, Google Translate, DeepL)

This release focuses on expanding language support with comprehensive Persian language integration and enhanced RTL text processing capabilities for Arabic, Hebrew, and Persian languages.

Release Date: 15 August 2025

This is a performance optimisation update that eliminates translation delays and network connection issues. All users are recommended to upgrade for significantly faster and more reliable translation performance.

🛠️ What's CHANGED in Version 3.5.3

🚀 Improvements

• ⚖️ Network Resilience System: A comprehensive solution to prevent Windows network stack corruption that caused API delays to increase after extended use

  • Circuit Breaker Pattern: Automatically detects network degradation (>3s calls or failures) and forces a client refresh when issues are detected.
  • Periodic Client Refresh: Proactively refreshes the Gemini client every 30 minutes or after 100 API calls to prevent connection staleness.
  • Connection Cleanup: Scheduled maintenance every 20 minutes to clear connection pools and prevent the accumulation of stale connections.
  • DNS Cache Management: Hourly system-level DNS cache flushing (ipconfig /flushdns) to address Windows network stack issues.
  • This self-healing behavior eliminates the need for PC restarts to restore performance.

• ⚖️ API Logging Performance Optimization: Eliminated an O(n) scaling issue in cumulative statistics calculation that caused increasing delays during extended use

  • Replaced file-based cumulative totals lookup with an efficient in-memory cache for OCR and translation operations.
  • Prevents log file reading overhead that grew progressively slower as usage history accumulated.
  • Maintains sub-second logging performance regardless of the application's runtime duration.

Release Date: 5 August 2025

This is a performance optimisation update that eliminates translation delays and improves system stability. All users are recommended to upgrade for significantly faster and more reliable translation performance.

🛠️ What's FIXED in Version 3.5.2

⚡ Performance Fixes

• 🔧 OCR Thread Artificial Delay Elimination: An important fix for a minor bug that was causing compound translation delays.

  • Before: The OCR thread was pausing artificially between processing queued images, causing delays of 3+ seconds.
  • After: Eliminated unnecessary artificial sleep intervals in the Gemini OCR thread processing. ✅
  • Impact: Restores consistent performance of ~2-second translations, eliminating compound delay scenarios.
  • Result: Maintains a proper, natural rate limit through API response times and thread pool capacity limits.

• 🔧 Concurrent Call Limits Optimisation: Improved system stability and performance under load.

  • Before: Higher concurrent call limits could cause API saturation and system instability.
  • After: Reduced the maximum concurrent OCR calls from 10 to 8 for better resource management. ✅
  • Impact: Reduced the maximum concurrent translation calls from 8 to 6 to prevent API saturation.
  • Result: Lowered the OCR overload detection threshold from >7 to >5 active calls for more responsive load balancing.

• 🔧 503 Error Suppression: Enhanced user experience during API overload scenarios.

  • Before: "503 UNAVAILABLE" errors were displayed in the translation window during API overload.
  • After: Added intelligent suppression of 503 errors from the translation window display. ✅
  • Impact: Errors are still logged for debugging but are now hidden from end-users.
  • Result: The application continues to work normally when the Gemini API recovers from a temporary overload.

🚀 Improvements

• ⚖️ Adaptive Load Balancing: More responsive system load detection and management.
  • OCR overload detection now triggers at >5 active calls instead of >7 for earlier intervention.
  • The improved load recovery threshold remains at <5 active calls for stable operation.
  • Enhanced system responsiveness during periods of high API usage.

  • Before: Successful OCR results were discarded due to timeout limits
  • After: Automatic Gemini client initialization ensures reliable OCR-to-translation pipeline ✅

• 🔧 Tesseract Path Validation Error with Gemini OCR Fixed: Resolved application startup and translation errors when Gemini OCR is selected

  • Before: "Tesseract path invalid!" error occurred even when Tesseract was not needed
