During July 2026, work on the keiyoushi/extensions-source repository centered on expanding Tachiyomi extension coverage by developing and updating three distinct sources. New extensions for GantzVN and Dilib were built using Kotlin and OkHttp, featuring custom network configurations, rate limiting, and tailored parsing logic for site-specific requirements such as Vietnamese date formatting and user agent handling. The MangaDüşleri extension was migrated to a custom HttpSource, introducing a login check interceptor and enhanced image handling to support a new site URL. Across all extensions, the developer emphasized architectural consistency, robust error handling, and streamlined repository maintenance using Gradle and Jsoup.
