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.
• 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.
