2026-06-15 - Blocked image attachments now explain what to do — enable vision via the "Editor preview features" policy, switch to a vision-capable model, or try a different image — instead of showing a confusing error. - Options in --help output sort alphabetically, including options that have two long flags - Auth validation errors (e.g., VPN or IP allowlist failures) are now shown in the sign-in banner with guidance to check network access - Show fork-based pull requests in /pr and the branch PR badge - Resume remote sessions when the local and remote repository names differ only by case - Show the spill file path when readbash output is too large - Include recent local sessions in /chronicle standup - Restore /responses WebSocket connections - Retry transient 401 auth failures in HMAC and OAuth modes - Press w in /diff to hide whitespace-only changes - Add deferTools option to MCP server config to keep a server's tools always available, even when tool search is enabled - Agent mode is tracked per session, so it no longer carries over when you create, clear, or switch sessions - Pressing Enter opens the highlighted issue details - Plan review menus work on strict OpenAI-compatible backends - Prevent Windows crashes when the native runtime addon loads in a corrupted host process heap - Recover from unreadable native document attachments by falling back to file-path uploads - Keep reverse search aligned in the input footer while you search command history - PostToolUse hook matchers (e.g. Edit|Write) are now honored instead of silently dropped, so formatters and linters run only after the tools they target - Improve reliability of OpenAI, Anthropic, and Azure OpenAI requests - Experimental: /rewind no longer requires git and restores only the files Copilot changed (leaving your own edits intact), with a conversation-only or conversation + files choice
