## 0.13.4

**Default startup behavior reverted to single-threaded experience.** Based on user feedback, `letta` (with no flags) now resumes the agent’s “default” conversation instead of creating a new conversation each time.

| Command                         | 0.13.0 - 0.13.3                    | 0.13.4+                     |
| ------------------------------- | ---------------------------------- | --------------------------- |
| `letta`                         | Creates new conversation each time | Uses “default” conversation |
| `letta --new`                   | Error (was deprecated)             | Creates a new conversation  |
| `letta --continue` (no session) | Silently creates new               | Errors with helpful message |

- Changed `letta` (no flags) to resume the “default” conversation with message history
- Repurposed `--new` flag to create a new conversation (for users who want concurrent sessions)
- Changed `--continue` fallback to error with helpful suggestions instead of silently creating new

## 0.13.3

- Added ability to deploy existing agents as subagents via the Task tool
- Fixed interrupt handling race condition when tool approvals are in flight

- Added output truncation for Task tool to prevent context overflow
- Added auto-cleanup for overflow files
- Fixed auto-allowed tool execution tracking for proper interrupt handling

## 0.13.1

- Added `--default` flag to access agent’s default conversation (alias for `--conv default`)
- Added `--conv <agent-id>` shorthand (e.g., `letta --conv agent-xyz` → uses that agent’s default conversation)
- Added default conversation to `/resume` selector (appears at top of list)
- Added `working-in-parallel` bundled skill for coordinating parallel subagent tasks
- Added conversation resume hint in exit stats
- Improved startup performance with reduced time-to-boot

- Fixed memory block retrieval for `/memory` command

## 0.13.0

**Where did my old conversation go?** If you upgraded from an earlier version and your previous messages seem missing, don’t worry! Your messages are in the agent’s **default conversation**. Just run `letta --agent <your-agent-id> --default` to access them.

This release introduces **Conversations** - a major change to how Letta Code manages chat sessions. Your agent can now have many parallel conversations, each contributing to its learning, memory, and shared history.

### What Changed

**Before 0.13.0:**

- Each agent had a single conversation
- Starting Letta Code resumed the same conversation
- `/clear` reset the agent’s context window

**After 0.13.0 (updated in 0.13.4):**

- Each startup resumes the **default conversation** (reverted from 0.13.0-0.13.3 behavior)
- Your agent’s **memory is shared** across all conversations
- `/new` creates a new conversation (for parallel sessions)
- `/clear` clears in-context messages
- Use `/resume` to browse and switch between past conversations
- Use `letta --new` to create a new conversation for concurrent sessions

### Migration Guide

If you’re upgrading from an earlier version, you may notice that starting Letta Code puts you in a **new conversation** instead of continuing where you left off. Here’s what happened:

**Your old messages still exist!** They’re in your agent’s **default conversation** - the original message history before conversations were introduced. You can find it at the top of the `/resume` selector, or access it directly with the commands below.

**Easiest way to access them (0.13.1+):**

Terminal window

```
# Use the --default flag with your agent name
letta -n "Your Agent Name" --default


# Or with agent ID
letta --agent <your-agent-id> --default


# Or use the shorthand (agent ID only)
letta --conv <your-agent-id>
```

The default conversation also appears at the top of the `/resume` selector.

**Alternative methods:**

1. **View them on the web** at `https://app.letta.com/agents/<your-agent-id>`

2. **Have your agent recall them** using one of these prompts:

   **Using the `recall` subagent:**

   ```
   Can you use the recall subagent to find our most recent messages? I'd like to continue where we left off.
   ```

   **Using the `conversation_search` tool:**

   ```
   Can you use conversation_search to find our most recent messages so we can continue where we left off?
   ```

   **Using the `searching-messages` skill:**

   ```
   Can you load the searching-messages skill and use it to find our most recent messages?
   ```

3. **Export and reference your agent file** by running `/export` (saves to `<agent-id>.af`), then ask your agent:

   ```
   I downloaded my agent file to ./agent-xxxx.af - can you read it and look through the "messages" array to find our most recent conversation?
   ```

Going forward, all new conversations will be accessible via `/resume`, and the default conversation is always available via `--default`.
