> Weekly Bolt changelog: GPT-5 reasoning effort now varies per model version, file selection toggles off on repeat click, and diff annotation polish.

## Updates

* **GPT-5 reasoning effort matches model version** — Reasoning effort tiers (including `none` and `xhigh`) are now offered only for the GPT-5 variants that support them, so `--variant` no longer surfaces options a given model would reject. See [Controlling reasoning effort](/concepts/providers-and-models#variant-controlling-reasoning-effort).
* **Diff annotation polish** — The session UI diff view tightens up comment indicators, gutter behavior, and light/dark syntax colors for better readability.

## Bug fixes

* **Toggle file selections off** — Clicking a file selection a second time now clears it, so you can undo a selection without picking a different one first.
* **Cleaner draft comment interactions** — Starting or dismissing a draft comment now clears the underlying selection consistently and no longer competes with hover state.
