# Release Notes
|
|
|
|
## v0.7.1
|
|
|
|
**Release Date:** March 13, 2026
|
|
**Tag:** v0.7.1
|
|
|
|
### Chrome-Native Browser Control
|
|
|
|
v0.7.1 replaces Playwright with direct Chrome DevTools Protocol (CDP) integration. The GCU now launches the user's system Chrome via `open -n` on macOS, connects over CDP, and manages browser lifecycle end-to-end -- no extra browser binary required.
|
|
|
|
---
|
|
|
|
### Highlights
|
|
|
|
#### System Chrome via CDP
|
|
|
|
The entire GCU browser stack has been rewritten:
|
|
|
|
- **Chrome finder & launcher** -- New `chrome_finder.py` discovers installed Chrome and `chrome_launcher.py` manages process lifecycle with `--remote-debugging-port`
|
|
- **Coexist with user's browser** -- `open -n` on macOS launches a separate Chrome instance so the user's tabs stay untouched
|
|
- **Dynamic viewport sizing** -- Viewport auto-sizes to the available display area, suppressing Chrome warning bars
|
|
- **Orphan cleanup** -- Chrome processes are killed on GCU server shutdown to prevent leaks
|
|
- **`--no-startup-window`** -- Chrome launches headlessly by default until a page is needed
|
|
|
|
#### Per-Subagent Browser Isolation
|
|
|
|
Each GCU subagent gets its own Chrome user-data directory, preventing cookie/session cross-contamination:
|
|
|
|
- Unique browser profiles injected per subagent
|
|
- Profiles cleaned up after top-level GCU node execution
|
|
- Tab origin and age metadata tracked per subagent
|
|
|
|
#### Dummy Agent Testing Framework
|
|
|
|
A comprehensive test suite for validating agent graph patterns without LLM calls:
|
|
|
|
- 8 test modules covering echo, pipeline, branch, parallel merge, retry, feedback loop, worker, and GCU subagent patterns
|
|
- Shared fixtures and a `run_all.py` runner for CI integration
|
|
- Subagent lifecycle tests
|
|

**Tag:** v0.5.1
|
|
|
|
### The Hive Gets a Brain
|
|
|
|
v0.5.1 is our most ambitious release yet. Hive agents can now **build other agents** -- the new Hive Coder meta-agent writes, tests, and fixes agent packages from natural language. The runtime grows multi-graph support so one session can orchestrate multiple agents simultaneously. The TUI gets a complete overhaul with an in-app agent picker, live streaming, and seamless escalation to the Coder. And we're now provider-agnostic: Claude Code subscriptions, OpenAI-compatible endpoints, and any LiteLLM-supported model work out of the box.
|
|
|
|
---
|
|
|
|
### Highlights
|
|
|
|
#### Hive Coder -- The Agent That Builds Agents
|
|
|
|
A native meta-agent that lives inside the framework at `core/framework/agents/hive_coder/`. Give it a natural-language specification and it produces a complete agent package -- goal definition, node prompts, edge routing, MCP tool wiring, tests, and all boilerplate files.
|
|
|
|
```bash
|
|
# Launch the Coder directly
|
|
hive code
|
|
|
|
# Or escalate from any running agent (TUI)
|
|
Ctrl+E # or /coder in chat
|
|
```
|
|
|
|
The Coder ships with:
|
|
|
|
- **Reference documentation** -- anti-patterns, construction guide, and design patterns baked into its system prompt
|
|
- **Guardian watchdog** -- an event-driven monitor that catches agent failures and triggers automatic remediation
|
|
- **Coder Tools MCP server** -- file I/O, fuzzy-match editing, git snapshots, and sandboxed shell execution (`tools/coder_tools_server.py`)
|
|
- **Test generation** -- structural tests for forever-alive agents that don't hang on `runner.run()`
|
|
|
|
#### Multi-Graph Agent Runtime
|
|
|
|
`AgentRuntime` now supports loading, managing, and switching between multiple agent graphs within a single session. Six new lifecycle tools give agents (and the TUI) full control:
|
|
|
|
```python
|
|
# Load a second agent into the runtime
|
|
await runtime.add_graph("exports/deep_research_agent")
|
|
|
|
# Tools available to agents:
|
|
# load_agent, unload_agent, start_agent, restart_agent, list_agents, get_user_presence
|
|
```
|
|
|
|
The Hive Coder uses multi-graph internally -- when you escalate from a worker agent, the Coder loads as a separate graph while the worker stays alive in the background.
|
|
|
|
#### TUI Revamp
|
|
|
|
The Terminal UI gets a ground-up rebuild with five major additions:
|
|
|
|
- **Agent Picker** (Ctrl+A) -- tabbed modal screen for browsing Your Agents, Framework agents, and Examples with metadata badges (node count, tool count, session count, tags)
|
|
- **Runtime-optional startup** -- TUI launches without a pre-loaded agent, showing the picker on first open
|
|
- **Live streaming pane** -- dedicated RichLog widget shows LLM tokens as they arrive, replacing the old one-token-per-line display
|
|
- **PDF attachments** -- `/attach` and `/detach` commands with native OS file dialog (macOS, Linux, Windows)
|
|
- **Multi-graph commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>` for managing agent graphs in-session
|
|
|
|
#### Provider-Agnostic LLM Support
|
|
|
|
Hive is no longer Anthropic-only. v0.5.1 adds first-class support for:
|
|
|
|
- **Claude Code subscriptions** -- `use_claude_code_subscription: true` in `~/.hive/configuration.json` reads OAuth tokens from `~/.claude/.credentials.json` with automatic refresh
|
|
- **OpenAI-compatible endpoints** -- `api_base` config routes traffic through any compatible API (Azure OpenAI, vLLM, Ollama, etc.)
|
|
- **Any LiteLLM model** -- `RuntimeConfig` now passes `api_key`, `api_base`, and `extra_kwargs` through to LiteLLM
|
|
|
|
The quickstart script auto-detects Claude Code subscriptions and ZAI Code installations.

### What's New
|
|
|
|
#### Architecture & Runtime
|
|
|
|
- **Hive Coder meta-agent** -- Natural-language agent builder with reference docs, guardian watchdog, and `hive code` CLI command. (@TimothyZhang7)
|
|
- **Multi-graph agent sessions** -- `add_graph`/`remove_graph` on AgentRuntime with 6 lifecycle tools (`load_agent`, `unload_agent`, `start_agent`, `restart_agent`, `list_agents`, `get_user_presence`). (@TimothyZhang7)
|
|
- **Claude Code subscription support** -- OAuth token refresh via `use_claude_code_subscription` config, auto-detection in quickstart, LiteLLM header patching. (@TimothyZhang7)
|
|
- **OpenAI-compatible endpoint support** -- `api_base` and `extra_kwargs` in `RuntimeConfig` for any OpenAI-compatible API. (@TimothyZhang7)
|
|
- **Remove deprecated node types** -- Delete `FlexibleGraphExecutor`, `WorkerNode`, `HybridJudge`, `CodeSandbox`, `Plan`, `FunctionNode`, `LLMNode`, `RouterNode`. Deprecated types (`llm_tool_use`, `llm_generate`, `function`, `router`, `human_input`) now raise `RuntimeError` with migration guidance. (@TimothyZhang7)
|
|
- **Interactive credential setup** -- Guided `CredentialSetupSession` with health checks and encrypted storage, accessible via `hive setup-credentials` or automatic prompting on credential errors. (@RichardTang-Aden)
|
|
- **Pre-start confirmation prompt** -- Interactive prompt before agent execution allowing credential updates or abort. (@RichardTang-Aden)
|
|
- **Event bus multi-graph support** -- `graph_id` on events, `filter_graph` on subscriptions, `ESCALATION_REQUESTED` event type, `exclude_own_graph` filter. (@TimothyZhang7)
|
|
|
|
#### TUI Improvements
|
|
|
|
- **In-app agent picker** (Ctrl+A) -- Tabbed modal for browsing agents with metadata badges (nodes, tools, sessions, tags). (@TimothyZhang7)
|
|
- **Runtime-optional TUI startup** -- Launches without a pre-loaded agent, shows agent picker on startup. (@TimothyZhang7)
|
|
- **Hive Coder escalation** (Ctrl+E) -- Escalate to Hive Coder and return; also available via `/coder` and `/back` chat commands. (@TimothyZhang7)
|
|
- **PDF attachment support** -- `/attach` and `/detach` commands with native OS file dialog. (@TimothyZhang7)
|
|
- **Streaming output pane** -- Dedicated RichLog widget for live LLM token streaming. (@TimothyZhang7)
|
|
- **Multi-graph TUI commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>`. (@TimothyZhang7)
|
|
- **Agent Guardian watchdog** -- Event-driven monitor that catches secondary agent failures and triggers automatic remediation, with `--no-guardian` CLI flag. (@TimothyZhang7)
|
|
|
|

|
|
- **Default `max_node_visits` → 0 (unlimited)** -- Nodes default to unlimited visits, reducing friction for feedback loops and forever-alive agents. (@TimothyZhang7)
|
|
- **Remove `function` field from NodeSpec** -- Follows deprecation of `FunctionNode`. (@TimothyZhang7)
|
|
- **LiteLLM OAuth patch** -- Correct header construction for OAuth tokens (remove `x-api-key` when Bearer token is present). (@TimothyZhang7)
|
|
- **Orchestrator config centralization** -- Reads `api_key`, `api_base`, `extra_kwargs` from centralized `~/.hive/configuration.json`. (@TimothyZhang7)
|
|
- **System prompt datetime injection** -- All system prompts now include current date/time for time-aware agent behavior. (@TimothyZhang7)
|
|
- **Utils module exports** -- Proper `__init__.py` exports for the utils module. (@Siddharth2624)

### Bug Fixes
|
|
|
|
- Flush WIP accumulator outputs on cancel/failure so edge conditions see correct values on resume
|
|
- Stall detection state preserved across resume (no more resets on checkpoint restore)
|
|
- Skip client-facing blocking for event-triggered executions (timer/webhook)
|
|
- Executor retry override scoped to actual EventLoopNode instances only
|
|
- Add `_awaiting_input` flag to EventLoopNode to prevent input injection race conditions
|
|
- Fix TUI streaming display (tokens no longer appear one-per-line)
|
|
- Fix `_return_from_escalation` crash when ChatRepl widgets not yet mounted
|
|
- Fix tools registration problems for Google Docs credentials (@RichardTang-Aden)
|
|
- Fix email agent version conflicts (@RichardTang-Aden)

|
|
|
|
---
|
|
|
|
### Breaking Changes
|
|
|
|
- **Deprecated node types raise `RuntimeError`** -- `llm_tool_use`, `llm_generate`, `function`, `router`, `human_input` now fail instead of warning. Migrate to `event_loop`.
|
|
- **`NodeSpec.node_type` defaults to `"event_loop"`** (was `"llm_tool_use"`)
|
|
- **`NodeSpec.max_node_visits` defaults to `0` / unlimited** (was `1`)
|
|
- **`NodeSpec.function` field removed** -- `FunctionNode` is deleted; use event_loop nodes with tools instead.

|
#### Migration Guide
|
|
|
|
If your agents use deprecated node types, update them:
|
|
|
|
```python
|
|
# Before (v0.5.0) -- these now raise RuntimeError
|
|
NodeSpec(node_type="llm_tool_use", ...)
|
|
NodeSpec(node_type="function", function=my_func, ...)
|
|
|
|
# After (v0.5.1) -- use event_loop for everything
|
|
NodeSpec(node_type="event_loop", ...) # or just omit node_type (it's the default now)
|
|
```
|
|
|
|
If your agents set `max_node_visits=1` explicitly, they'll still work. The only change is the _default_ -- new agents without an explicit value now get unlimited visits.
|
|
|
|
To try the new Hive Coder:
|
|
|
|
```bash
|
|
# Launch Coder directly
|
|
hive code
|
|
|
|
# Or from TUI -- press Ctrl+E to escalate
|
|
hive tui
|
|
```
|
