+# 0.2.89 — 2026-07-07
+
+## Features
+
+- **Voice dictation** now works on Linux (requires pipewire, pulseaudio-utils or alsa-utils).
+- **New /auto slash command** switches to classifier permission mode; the menu now shows only the other mode.
+- **--effort** and **--reasoning-effort** are now interchangeable CLI flags for setting reasoning effort.
+- **Image edits** now use the higher-quality Imagine model for better output.
+
+## Bug Fixes
+
+- **Try Again** on the free-usage paywall now correctly resubmits after rate-limit retries.
+- **Cursor** now respects your terminal's default blink style instead of always blinking.
+- **Skill commands** in scrollback now highlight only the command name, not the arguments.
+- **Plan files** now default to .grok/plan.md to match Grok conventions.
+- **LaTeX math** renders correctly for display equations and complex subscripts.
+- **Queue hint** in the terminal no longer shows incorrect bold text on part of the message.
+
+## Performance
+
+- **Git operations** like rebase no longer cause long pauses from repeated full-repo scans.
