v0.13.0

Release date: 2026-06-09

Added

Added a Google Cloud provider for Vertex/Gemini, OpenAI-compatible MaaS, xAI, and Anthropic-shaped models, including CLI, sandbox, web settings, authentication, endpoint, documentation, and test coverage (81bbb585).
Added default init catalog bootstrapping so pbi-agent init installs starter commands and sub-agents with safer disabled-state rollback handling (2ab3b92d, 36a911e5).
Added an Explorer sub-agent for codebase exploration workflows (d7ecdaeb).

Defaulted the web appearance theme to System and expanded coverage for theme selection behavior (e41be131).
Refactored provider backends around shared auth, endpoint, transport, protocol, runtime, and tool-execution helpers for more consistent provider behavior (f57e2b4f).
Loaded workspace memory into main and sub-agent system prompts after project rules so durable workspace context is consistently available (e42d7bf9).

Fixed cross-provider saved-session tool history replay when raw traces are incompatible between providers (c3346d56).
Persisted the final assistant message for Responses-style providers to improve saved-session continuation and replay fidelity (e9136790).
Hid diff metadata and hunk headers from session diff previews for a cleaner workspace review view (481932f8).

Refined built-in worker, execute, and review command guidance for clearer mode expectations (8f955e2b).

Compacted workspace memory task history and promoted durable release/provider details into long-term memory (1cf154d9).
