 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.5.1] - 2026-03-05
+
+### Breaking Changes
+
+- **`data-browser-use-ignore` → `data-page-agent-ignore`** - DOM ignore attribute renamed to match the project identity
+- **Config types restructured** - `PageAgentConfig` split into `AgentConfig` + `PageAgentCoreConfig`; config definitions moved from `config/index.ts` to `types.ts`
+- **Zod v3/v4 dual support** - Libraries now accept both `zod@^3.25` and `zod@^4.0` as peer dependencies
+
+### Features
+
+- **Experimental `llms.txt` support** - Agent can fetch and include a site's `llms.txt` in context. Enable via `experimentalLlmsTxt: true`
+
+### Improvements
+
+- Default `maxSteps` changed from 20 to 40 for better for complex tasks out of the box
+- Added 400ms wait between agent steps for page reactions
+- Increased click wait time (100ms → 200ms) for more reliable interactions
+- Removed debug `console.log` statements from scroll actions
+- Reset observations on new task start
+- Improved logging across packages
+
+### Extension v0.1.9
+
+> PageAgent 1.5.1
+
+- **Advanced config panel** - New collapsible section exposing Max Steps, System Instruction, and experimental `llms.txt` toggle
+- Streamlined User Auth Token description
+- Moved testing API notice below auth token section
+
+---
+
+## [1.4.0] - 2026-02-27
+
+### Features
+
+- Update Terms of Use and Privacy Policy
+- **Robust tool-call validation** - Action inputs are now validated against tool schemas individually, producing clear error messages (e.g. `Invalid input for action "click_element_by_index"`) instead of unreadable union parse errors
+- **Primitive action input coercion** - Small models that output `{"click_element_by_index": 2}` instead of `{"click_element_by_index": {"index": 2}}` are now auto-corrected using tool schemas
+- **Qwen model updates** - Added `qwen3.5-plus` as the default free testing model; disabled `enable_thinking` for Qwen models to avoid incompatible responses
+- **Updated default LLM endpoint** - Migrated demo and extension to a new testing endpoint with legacy endpoint auto-migration
+
+### Improvements
+
+- Unified zod imports (`* as z`) across all packages for consistency
+- Better Zod error formatting with `z.prettifyError()` in LLM client
+- Exported `InvokeError` and `InvokeErrorType` as values (not just types) from `@page-agent/llms`
+- Exported `SupportedLanguage` type from `@page-agent/core`
+
+### Extension v0.1.8
+
+- **Language setting** - Added language selector (System / English / 中文) in config panel
+- **UI makeover** - New empty state with breathing glow and typing animation; ai-motion glow overlay while running; refined focus styles
+- **Testing endpoint notice** - Shows terms of use notice when using the free testing API
+- **Legacy endpoint migration** - Auto-migrates old Supabase testing endpoint to new endpoint on startup

-Page Agent Ext — AI-Powered Browser Automation
-
-🌟 What is Page Agent Ext?
-
-Page Agent Ext brings AI-powered automation to your browser. Built on the open-source Page Agent framework, it lets you control web pages across multiple tabs using natural language — no scripting required.
-
-🌟 Key Features:
-
-- Natural Language Control — Command your browser in plain language, no code needed
-- Cross-Tab Automation — Seamlessly operate across multiple tabs and pages
-- Smart HTML Cleaning — Intelligently extracts and simplifies page structure for accurate AI understanding
-- Bring Your Own LLM — Use OpenAI, Anthropic, or any compatible API with full data control
-- Privacy-First — Zero data collection; all data flows directly to your chosen LLM provider
-- Open Source — MIT licensed, built on the Page Agent framework with full transparency
-
-🌟 How It Works & Privacy:
-
-Page Agent Ext performs DOM analysis locally in your browser. When you initiate a task, sanitized page structure is sent to the LLM API you configure. Your data is never collected or stored by us.
-
-- Your API Key — Configure your own LLM API (OpenAI, Anthropic, etc.). Data goes directly to your provider
-- Test API — A free test endpoint is available for evaluation; we recommend your own key for regular use
-
-Terms of Use & Privacy: https://github.com/alibaba/page-agent/blob/main/docs/terms-and-privacy.md
-
-🌟 Open Source:

-Page Agent Ext — AI 驱动的浏览器自动化助手
-
-🌟 什么是 Page Agent Ext？
-
-Page Agent Ext 为浏览器带来 AI 自动化能力。基于开源的 Page Agent 框架，你可以用自然语言跨标签页控制网页，无需编写任何脚本。
-
-🌟 核心特性：
-
-- 自然语言控制 — 用日常语言指挥浏览器，无需编程
-- 跨标签页操作 — 在多个标签页之间无缝切换和操控
-- HTML 智能清洗 — 智能提取和精简页面结构，让 AI 准确理解网页内容
-- 使用你自己的模型 — 支持 OpenAI、Anthropic 或任何兼容 API，数据完全自主可控
-- 隐私优先 — 零数据收集，所有数据直接发送到你配置的 LLM 服务商
-- 开源透明 — MIT 协议，基于 Page Agent 开源框架，代码完全公开
-
-🌟 工作原理与隐私：
-
-Page Agent Ext 在浏览器本地进行 DOM 分析。当你发起任务时，经清洗的页面结构会发送到你配置的 LLM API。我们不会收集或存储你的任何数据。
-
-- 你的 API Key — 配置你自己的 LLM API（OpenAI、Anthropic 等），数据直接发送到你的服务商
-- 测试 API — 提供免费测试端点供体验，日常使用建议配置自己的 Key
-
-使用条款与隐私：https://github.com/alibaba/page-agent/blob/main/docs/terms-and-privacy.md
