𝙊𝙥𝙚𝙣𝘾𝙤𝙙𝙚 v1.15.6 released. TL;DR: TUI gets /diff + shell mode; v2 API errors are now typed; desktop/app shell gets cross-platform menu work; plugins/native LLM paths get stricter. 𝗧𝗨𝗜 & 𝗖𝗟𝗜 • Added a full-screen TUI diff viewer: working tree vs last assistant turn, file tree navigation, collapsed directory chains, split/unified views, single-patch mode, and configurable diff keybinds. • `opencode run --interactive` now has shell mode: start from an empty prompt with `!`, send direct shell commands through the session shell path, and render shell transcript output without treating it as a normal user prompt. • Replaced subagent tabs with an on-demand searchable picker, keeping subagent inspection available without consuming footer space. • Zed editor context is now gated on the Zed terminal environment, avoiding accidental Zed DB selection pickup from unrelated terminals. 𝗛𝗧𝗧𝗣 𝗔𝗣𝗜 & 𝗦𝗗𝗞 • v2 API failures now expose public typed error schemas: invalid cursors/requests, auth failures, missing providers/models/sessions/messages, busy sessions, upstream/service-unavailable/timeout cases. • v2 auth now returns structured JSON errors instead of no-content 401s, and catalog/model/provider failures surface as explicit API errors. • OpenAPI + JS SDK were regenerated so clients can see these error unions instead of guessing from status codes. 𝗣𝗿𝗼𝘃𝗶𝗱𝗲𝗿𝘀, 𝗣𝗹𝘂𝗴𝗶𝗻𝘀, 𝗧𝗼𝗼𝗹𝘀 • Native LLM runtime now supports Anthropic API-key models in addition to OpenAI/opencode routes, with cleaner API-key resolution from provider config. • TUI plugin keymaps gained mode-aware layers via `api.mode`, so plugin shortcuts can be scoped to base UI, modals, autocomplete, or plugin-owned routes. • Plugin loading now only retries pre-import file-plugin setup failures; permanent import/load errors stay permanent for the process. • Plugin tools with missing `args` are tolerated again, matching older plugin behavior. 𝗗𝗲𝘀𝗸𝘁𝗼𝗽 & 𝗔𝗽𝗽 • Desktop menus were unified through a shared menu model: native macOS menu plus in-app Windows/Linux menu, covering settings, projects, window actions, edit commands, reload/devtools, zoom, fullscreen, and help links. • App sync was split into reusable per-directory contexts, enabling cleaner multi-directory/session state sharing and immediate provider-list invalidation after config updates. • Added Ukrainian locale coverage across app/console/desktop/ui/web surfaces. 𝗖𝗼𝗻𝘀𝗼𝗹𝗲 / 𝗚𝗼 • OpenCode Go referral support landed: invite links, referral cookie capture on signup, reward creation after Lite subscription, and reward application against rolling/weekly/monthly usage. 𝗙𝗶𝘅𝗲𝘀 • `opencode console login` now defaults to `console.opencode.ai` when no URL is passed. • Imported shared sessions now get the current project, directory, and relative path persisted correctly. • Invalid `OPENCODE_PERMISSION` JSON no longer crashes config loading. • Agent/command config names are derived from anchored relative paths, avoiding bad names when parent directories happen to contain matching path segments.
