1.0.55-3

Added

• Hook progress streaming shows real-time status messages from long-running hooks in the timeline
• pluginDirectories on session.create and session.resume RPC: SDK clients can mount Open Plugins-format directories per session.
• Delete remote sessions directly from the session picker

Improved

• Support owner/repo#ref syntax when adding plugins from the marketplace
• Feedback dialog and /skills help text use Copilot-consistent log paths and terminology
• Progress indicators integrate natively with tmux 3.6b pane progress state
• --plugin-dir skills now take precedence over personal-home (~/.copilot, ~/.agents) skills with the same name. Order is now project > plugin-dir > personal > custom.
• Show a helpful message when remote controlled sessions are disabled by organization policy
• Reasoning token count now shown in session token summary for all users

Fixed

• Schedule manager hint bar text no longer wraps over dialog borders when entries are added

• Diff view keyboard shortcut hints display correctly when toggling between unstaged and branch diff modes
• Clipboard paste works correctly on Wayland compositors that do not support wlr-data-control (e.g. GNOME/Mutter)
• Interactive shell tool preserves parent terminal color settings so diff tools and other programs render with full color
• Canvas tools with optional object input schemas open correctly without validation errors
• Extension subprocesses no longer fail with "Invalid command format" when forked from an older CLI version

• Non-interactive subcommands (plugin list, mcp list, help, version) no longer consume stdin
• Add vertical scrollbar with mouse drag support to the main conversation view
• Switching to Autopilot mode no longer triggers unexpected permission prompts for tool, path, or URL access

• Kill command safety filter no longer rejects valid commands that contain shell redirection like kill -0 <PID> 2>/dev/null.
• Sessions now resume in their saved working directory; pass -C to override. Flags whose values are relative paths (e.g. --attachment, --log-dir) resolve from the saved cwd.
• Context window tier selection (default ~200K vs 1M tokens) is now enforced end-to-end, so picking a tier actually constrains compaction, truncation, and token display

• Slash command picker keeps (experimental) and (staff) labels orange when the row is selected
• Reasoning tokens display as a parenthetical on output token count in the token usage summary
• Sessions containing events with non-URL strings in URL/URI fields resume without a 'Session file is corrupted' error
• Requests that time out due to an HTTP/2 upload stall automatically retry over HTTP/1.1

• Status line command supports plain shell commands in addition to executable script paths

• Polish /statusline picker with cleaner item descriptions and better spacing
• Picker checkboxes now use a single-cell ▣/▢ glyph for tighter, more consistent rows across pickers
• Custom agents support opt-in deferred tool loading via deferred-tool-loading in agent frontmatter, enabling tool-search discovery for agents with large tool lists
• Exit summary displays AI Credits label with correct spacing before the value
• /restart and /update preserve the current session ID after restarting
• Legacy nested oauth.clientId and oauth.callbackPort keys in MCP server configs are now migrated to the supported oauthClientId and auth.redirectPort keys instead of being silently dropped

• General-purpose subagents use GPT-5.4 or GPT-5.5 when available
• /usage shows quota progress bars for session and weekly limits
