Version 3.5.1

Released on 2026-09-01

FTMGram v3.5.1 is a rock-solid performance and stability release that resolves import-time file handle exhaustion on Linux/uvloop environments and introduces Turbo Parallel File Uploads.

Highlights

• Bugfix: Linux `Too many open files` [Errno 24] Resolved: Fixed an issue in sync.py and utils.py where event loops were repeatedly created during import wrapping. Event loop retrieval is now fully lazy and safe on multi-threaded and uvloop container environments.

• ⚡ Turbo Multi-Worker Media Uploads (`fast_upload`): Upload large files (videos, documents, archives) at maximum speed by streaming 1MB chunk parts concurrently across 8-16 parallel workers using upload.saveBigFilePart.

• ⚡ Turbo Multi-Worker Media Downloads (`fast_download`): Download media files concurrently with chunk worker saturation.

• 🤖 Bot Chat History Retrieval (`get_bot_chat_history`): Safe 100-ID batch scanning for bots in private chats and groups without ban risk.

• 🎨 Fluent `RichMessageBuilder` DSL: Construct structured rich messages with <tg-button-row>, expandable quotes, tables, and paragraphs effortlessly in Python.

• 🧠 Real-Time AI Streaming (`stream_text` & `thinking`): Stream LLM tokens directly to chat drafts with animated placeholders.
