# Changelog

User-visible changes from build 1.0 through build 2.0.


This page summarizes changes that affect how you use the app, with the latest build first. It is not a list of every worker update or minor bug fix.

Features from older versions may no longer exist. In particular, built-in AI was removed in build 1.2. The current version accepts commands from external AI through connections with their own permissions.

## Build 2.0 — Public documentation

- Public documentation in Vietnamese (`/docs`) and English (`/en/docs`): getting started, concepts, guides, integrations, safety, and troubleshooting.
- REST, MCP, event, error code, permission, and quota references generated from product code.
- A Markdown version of each page; `llms.txt` and a read-only documentation MCP server for AI agents.
- AI agent playbooks: check accounts, handle the Inbox, draft campaigns, investigate failed jobs, and work with webhooks.
- Screenshots captured from a Demo workspace with fictional data, checked by automated privacy checks and a human reviewer.

## Build 1.9 — Vietnamese and English

- Added a bilingual Vietnamese–English interface.
- Aligned system content and reference information with the selected language.
- Data you enter stays unchanged and is not replaced with automatically translated content.

## Build 1.8 — Groups, channels, and bots

- Added centralized group and channel management, with Follow support to bring conversations into the Inbox.
- Expanded management of members, permissions, invite links, and group settings.
- Added ownership transfer and group or channel deletion with sensitive-action confirmation.
- Added management of each account's bots, with protected tokens.
- Added internal account marking to exclude team accounts from discovery and outreach flows.
- Improved incoming-message synchronization and group-change notifications.

## Build 1.7 — Webhooks and receivers

- Standardized signed webhooks so external systems can verify the sender.
- Added event content levels, filters, and test tools.
- Added delivery tracking, automatic retries, and automatic disabling after persistent receiver failures.
- Added delivery resends and event replay.
- Agents can set up webhooks within their granted scope; risky actions still require appropriate confirmation.

## Build 1.6 — Expanded Inbox and integrations

- Expanded message, contact, profile, and privacy operations.
- Added more group, channel, and topic operations.
- Added polls, bot buttons, scheduled messages, stickers, and Stories.
- Expanded REST and MCP so external systems use the same permission checks.
- Added API documentation and improved page navigation.

## Build 1.5 — Two quota modes

- Added **Free** and **Safe**.
- New accounts use Free by default; you can set custom limits.
- Free still respects Telegram's wait requirements and safety checks.
- Added the **Rest hours** option for the relevant activity schedules.

## Build 1.4 — Open conversations faster

- Reduced the wait when opening chats.
- Improved handling of consecutive sends.
- Kept all sending safety checks.

## Build 1.3 — See outgoing messages sooner

- Show a bubble as soon as sending a message or file begins.
- Keep content easier to follow while history is loading.
- Restore the draft when sending fails instead of automatically resending after a network loss.

## Build 1.2 — Removed built-in AI

- Removed in-app AI drafting and reply flows.
- Kept manual sends, templates, and commands from external systems on the same safety-check path.
- Kept the Inbox, People, Discover, campaigns, and account nurturing.

## Build 1.1 — Contacts and basic groups

- Added messaging by phone number or username.
- Added saving contacts and creating basic groups.
- Show people who could not be added to a group and distinguish sender names.

## Build 1.0 — Initial foundation

- Launched workspaces, members, accounts, proxies, and machines.
- Added Telegram sign-in by QR code or phone number.
- Added a shared Inbox, People, Discover, campaigns, and account nurturing schedules.
- Added alerts, statistics, API integrations, and webhooks.
- Added worker support for multiple accounts and updates with release checks.
