v2026.6.30-2

Added

• Added inherited Anthropic Claude Sonnet 5 model support.
• Added get_entries and get_tree RPC commands for reading session entries and tree snapshots over RPC (#6078 by @geraschenko).
• Added session-name change events for extensions (#6175 by @xl0).
• Added an outputPad setting for user message, assistant message, and thinking horizontal padding (#6168).

Changed

• Changed inherited OpenAI Codex Responses SSE response-header waits to use the configured HTTP timeout instead of the previous fixed 20 second timeout, reducing false timeouts on slow connections (#4945).

Fixed

• Fixed inherited Claude Sonnet 5 metadata to use adaptive thinking payloads for Anthropic-compatible and Bedrock requests.
• Fixed inherited generated Xiaomi MiMo model pricing to match current pay-as-you-go pricing from models.dev (#6138).
• Fixed inherited provider HTTP errors to include response bodies instead of opaque SDK messages (#5832 by @stephanmck).
• Fixed inherited Z.AI preserved thinking requests to send thinking.clear_thinking: false when thinking is enabled, allowing replayed reasoning_content to participate in provider caching (#6083).
• Fixed pre-prompt compaction to stop after compaction instead of continuing immediately (#6074 by @yzhg1983).
• Fixed extension tool changes to apply before the next provider request in the same agent run without dropping before_agent_start system-prompt overrides (#6162).
• Fixed a crash when undici emits an internal client error while terminating a mid-stream HTTP response (#6133).
• Fixed interactive status indicators so ending work, retry, compaction, or branch-summary indicators no longer shrink the TUI when clear-on-shrink is enabled (#6026).
• Fixed fork interactive working status updates to preserve elapsed timing and active tool labels after upstream status indicator changes.
• Fixed fork compaction status handling to preserve overflow/pre-prompt reasons and progress rendering after upstream merge.
