OpenCode v1.4.0 — changelogs.info

Breaking Changes in SDK

Due to some performance issues we had to make a few breaking changes in our data model.

Diff metadata

The diffs contained in the metadata for the edit and patch tool will no longer contain a to and from field with full file contents. they will only contain a patch field with the unified diff Additionally all snapshot diffs contained in user message and session diff will follow this format

`UserMessage.variant`

Before the user message had a variant field - it is now nested under model so userMessage.model.variant

Core

Added OTLP observability export support.

Fixed failed web fetches leaving stale timeouts behind.

Improved opencode login transport error messages.

Retried Alibaba provider rate-limit errors instead of failing immediately.

Kept model variants scoped to the selected model.

Added full HTTP proxy support.

Fixed OpenRouter provider issues.

Aligned GitHub Copilot Anthropic reasoning levels and removed incorrect Qwen variants.

Reduced TypeScript LSP memory use by using the native project config. (@derekbar90)

TUI

Added a keybinding option for "Switch model variant". (@ariane-emory)

Added PDF drag and drop for attachments. (@gitpush-gitpaid)

Added opencode run --dangerously-skip-permissions to auto-approve non-denied permission prompts.

Desktop

Improved subagent sessions with clearer titles, navigation, and progress states.

Moved auto-accept permissions into Settings.

Showed full file names on attachment chips.
