OpenCode v1.16.2 の変更点

Core

Bugfixes

• Reasoning summaries now only run on providers that support them, avoiding GPT-5 request failures on compatible backends.

• Edit operations now refuse loose matches that could overwrite the wrong code or replace an existing file by mistake.

• Fixed Bedrock sessions hanging before a model response starts. (@alblez)

Improvements

• Diff viewer now supports next and previous hunk navigation.

• Terminal themes now refresh after live terminal reloads without stale colors or broken highlighting.

• Running subagents can now be sent to the background so you can keep working.

• Sessions now persist system context updates during long-running conversations.

• Added Snowflake Cortex provider support. (@kameshsampath)

TUI

Bugfixes

• Fixed the external editor fallback so attach-mode sessions still open when the original project path is unavailable locally. (@pcadena-lila)

• Permission replies now route through the correct session directory.

• /mo now prefers the models command in slash autocomplete.

• Fixed crashes from malformed path or diff metadata in permission and session views.

Desktop

Bugfixes

• Fixed titlebar tab overflow clipping.

• Fixed overflowed titlebar tabs so scrolling and drag regions behave correctly.

• Improved tab closing and navigation so the next tab is selected more reliably.

Improvements

• Improved multi-server desktop support with per-server home state and session tabs.
