Changelog

All notable changes to this project are documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.3.1]

Fixed

• In group chats the bot no longer replies "I don't know how to read files or videos" to videos and documents it wasn't mentioned in — unsupport_message_handle now respects the same is_bot_mentioned check as the other handlers (#454).

Security

• Bumped python-dotenv 1.0.1 → 1.2.2 to resolve a symlink-following advisory in set_key (Dependabot).

[1.3.0]

Removed

• Legacy gpt-3.5-turbo and gpt-4 models from the menu and config — the lineup is now gpt-4o-mini (default), gpt-5.5, gpt-4o and the Claude models.

Changed

• Simplified the token-count overhead table (all current chat models share the same overhead).
• Refreshed the README (title and feature list) to drop legacy GPT-4 mentions.

Fixed

• /balance no longer raises a KeyError for users with historical usage of models that have since been removed from the config.

[1.2.0]

Added

• Minimal GitHub Actions CI: installs requirements on Python 3.12 and byte-compiles the bot on every push and pull request.

Changed

• Image generation now uses OpenAI gpt-image-1 (default size 1024×1024); images are returned as bytes and /balance / pricing updated accordingly.
• Updated gpt-4o pricing to current rates (0.0025 / 0.01 per 1k tokens).

Removed

• Deprecated models gpt-3.5-turbo-16k, gpt-4-1106-preview and gpt-4-vision-preview from the model menu (gpt-4o / gpt-4o-mini cover them).

[1.1.0]

Added

• OpenRouter provider support: models can declare provider: openrouter in models.yml and are routed through an OpenAI-compatible OpenRouter client. New openrouter_api_key / openrouter_api_base config options.
• Anthropic Claude models via OpenRouter: Claude Opus 4.8, Claude Sonnet and Claude Haiku.
• OpenAI gpt-5.5 (via OpenRouter).

Changed

• Chat models are now dispatched by their type in models.yml instead of hardcoded model-name lists, so adding a model is a config-only change.
• Token counting falls back to the o200k_base encoding for models unknown to tiktoken (e.g. Claude).
• The /settings model picker lays buttons out in rows of two to stay within Telegram's per-row inline-button limit.
• Image understanding is now driven by a vision: true flag in models.yml, so any vision-capable model (GPT-4o, GPT-4o mini, GPT-5.5, Claude) can read images — no longer limited to GPT-4o / GPT-4 Vision.

[1.0.0]

Added

• gpt-4o and gpt-4o-mini models, with gpt-4o-mini as the new default.
• VERSION file and this changelog.

Changed

• Migrated from the deprecated openai==0.28 API to the openai>=1.x SDK (AsyncOpenAI client, new chat/image/audio/moderation methods, updated error classes).
• Default model is now gpt-4o-mini instead of the outdated gpt-3.5-turbo (new users, /new, and the ChatGPT fallback).
• Upgraded the Docker base image to Python 3.12 (3.8 is end-of-life).
• Bumped dependencies: python-telegram-bot 20.8, pymongo 4.6.3, PyYAML 6.0.2, python-dotenv 1.0.1, tiktoken >= 0.7.0.
• Docker: smaller image (pip --no-cache-dir), unbuffered logs (PYTHONUNBUFFERED), live-mounted config, expanded .dockerignore, removed the obsolete Compose version key.

Removed

• text-davinci-003 and its legacy completion code paths (the model was shut down by OpenAI).

Fixed

• Corrected gpt-4o pricing and scores in models.yml.
• tiktoken now recognizes the o200k_base encoding used by gpt-4o.
• Removed debug logging that fired on every incoming message.
• Narrowed bare except: clauses so shutdown/cancellation propagates.
• Stopped tracking .DS_Store; various typo and docs fixes.
