-## What's New in v1.5.0
+## What's New in v1.6.0
 
-- **MCP SDK v1.25.2**: Latest Model Context Protocol SDK with enhanced compatibility
-- **New Tool**: `structuredConversationFilter` for ID-based refinement and ticket number lookup
-- **Security Improvements**: Enhanced input validation and error handling from code review
-- **Tool Discovery**: Clearer descriptions and decision tree for better LLM tool selection
-- **Auth Alignment**: Standardized environment variable naming (`APP_ID`/`APP_SECRET`)
-- **Content Redaction**: Renamed to `REDACT_MESSAGE_CONTENT` for clarity
+- **Inbox Auto-Discovery**: Inboxes automatically discovered on server connect and included in server instructions—no need to call `searchInboxes` first
+- **Multi-Status Search Default**: `searchConversations` now searches all statuses (active, pending, closed) by default when no status specified
+- **Simpler Workflow**: AI agents can use inbox IDs directly from server instructions without a preliminary lookup step
+- **Deprecated Tools**: `searchInboxes` and `listAllInboxes` remain functional but are deprecated (inboxes now in instructions)
+
+### Previous Release (v1.5.0)
+
+- MCP SDK v1.25.2 with enhanced compatibility
+- `structuredConversationFilter` for ID-based refinement and ticket number lookup
+- Enhanced input validation and error handling
+- Standardized environment variable naming (`APP_ID`/`APP_SECRET`)
+
+### Migration from v1.5.0
+
+**For programmatic users:**
+- `HelpScoutMCPServer` now uses an async factory pattern: use `await HelpScoutMCPServer.create()` instead of `new HelpScoutMCPServer()`
+
+**Response format change:**
+- `searchConversations` response now includes `statusesSearched` array instead of `status` string when searching without a specific status filter
+
+**No action required for most users** - the MCP protocol interface remains unchanged.

+### Inbox Auto-Discovery (v1.6.0+)
+
+When the server connects, it automatically discovers all available inboxes and includes them in the server instructions. AI agents can reference inbox IDs directly without calling lookup tools first.
+
+Example server instructions snippet:
+```
+## Available Inboxes (3 total)
+  - "Support Inbox" (ID: 12345)
+  - "Sales Inquiries" (ID: 67890)
+  - "Billing Questions" (ID: 24680)

 **Empty Search Results**
 - **Wrong tool choice**: Use `searchConversations` (no query) for listing, `comprehensiveConversationSearch` for content search
 - **Empty search terms**: Don't use empty strings `[""]` with comprehensiveConversationSearch
+- **Inbox ID issues**: Use inbox IDs from server instructions (auto-discovered on connect), not guessed values
 - Verify inbox permissions with your API credentials
 - Check conversation exists and you have access
 - Try broader search terms or different time ranges
