• Free and Student users can select models other than Auto in the model picker
• ThemePicker side-by-side layout fits within a 120-column terminal without wrapping
• Model picker shows accurate total context window size per pricing tier
• Add builtInAgents.rubberDuck setting to enable or disable the rubber duck agent via copilot config
• Extended key reporting works correctly in tmux when Kitty keyboard protocol is unavailable
• Config and settings files are written atomically to prevent data loss when multiple CLI processes run concurrently
• BYOK provider configuration now applies correctly to ACP sessions
• MCP tools that return both human-readable content text and a structuredContent payload now surface both to the agent instead of dropping either side. When the text is the literal JSON serialization (per MCP spec §5.2.6) it is deduplicated; otherwise the two are concatenated.
• Fix /context small-token legend formatting and free-space grid rounding
• Reasoning effort picker respects model capabilities — options not supported by the model are no longer shown
• File paths in /env output display with correct formatting
• Reasoning text always displays above the assistant response in the conversation timeline
• Assistant responses render without single-word orphan lines in the terminal timeline
• Diff view uses a continuous scroll layout with sticky file and hunk headers, full terminal width, and theme-aware colors
• web_fetch tool prefers markdown content when available, using HTTP content negotiation for cleaner results from documentation sites
• Cursor stays at correct position after pasting text that contains tab characters
• Code review agent now uses the same model as the current session instead of a fixed default
• When gh CLI is on PATH, GitHub MCP server now omits redundant gh-replaceable tools by default, reducing token usage
• Context window tier selection now persists durably in session events and survives SDK-only resume paths so tier-derived limits are reapplied to request, compaction, and truncation logic without app-level repair
• Remote session URL correctly uses the repository owner/name instead of literal 'copilot'
• Trusted folder confirmation message clarifies that permissions may be remembered for the session
