- Add Free_Proxy_Website-style fpw_* plugins and register them - Per-plugin crawl timeout (crawl_timeout_seconds=120); remove global crawl_timeout setting - Validator: fix connect vs total timeout on save; SOCKS session LRU cache; drop redundant semaphore - Validation handler uses single DB connection; batch upsert after crawl; WorkerPool put_nowait - Remove unused max_retries from settings API/UI; settings maintenance SQL + init_db cleanup of deprecated keys - WebSocket dashboard stats; ProxyList pool_filter and API alignment - POST /api/proxies/delete-one for IPv6-safe deletes; task poll stops on 404 - pytest uses PROXYPOOL_DB_PATH=db/proxies.test.sqlite so tests do not wipe production DB - .gitignore: explicit proxies.test.sqlite patterns; fix plugin_service ValidationException import Made-with: Cursor
