• Fix app failing to launch with AttributeError: 'AuthManager' object has no attribute 'token_refreshed' — orphan signal connection left behind by the 1.0.1 single-token cleanup
• Active Issues dialog now headlines self-test root causes and standby state for CPC/PSM, so downstream temperature/pressure/voltage symptoms are no longer chased before the actual fault
• Status bar device pill flips to an orange STANDBY indicator when the firmware parks the device
• IO worker re-queries :STAT:SELF:LOG every 5 minutes so a fixed-and-reset device clears its standby/self-test state without needing a reconnect
• Sim button gains (with errors) variants for CPC and PSM that drive the new path without real hardware
• Drop stale warnings from the Active Issues dialog when a device is removed (was rendering as Unknown)

• Cloud sync: keep retrying after a failed upload instead of permanently disabling; a single transient auth or network error no longer silences the session until a manual re-enable
• Simplified cloud authentication: single long-lived token, no more silent refresh dance

• PSM live inversion and history view
• AI chat and cloud sync (requires sign-in)
• Command palette with instant fuzzy search (Ctrl+K)
• Serial port selection dialog with automatic device type detection
• Redesigned serial IO handling with slot-based priority queuing
• AFC (Airmodus Flow Controller) device type support
• CPC ACTRIS database saving support
• Various UI/UX improvements

Serial port handling

• Track ports assigned to device widgets to prevent reconnection blocking
• Skip port query for ports already assigned to a device
• Check port availability when opening dialog and selecting a port
• Skip built-in and virtual ports in port scanner
• Query unrecognized devices multiple times before giving up
• Reduced port scanner interval to 1 second
• Show full IDN string in port selection dialog
• Fix occasional freeze when closing serial connection
• Fix tab menu "Select Port" and "Disconnect" actions

bug fixes

• Fix legend not updating when removing the last device

refactoring

• Rename close() to close_connection() to avoid confusion with Serial.close()
• Rename widget.connection to widget.device_connection to avoid confusion with the underlying Serial object
• Remove unused set_inquiry_flag, disable_dtr, and _parse_idn_response

Command palette and AI navigation

• Command palette with instant fuzzy search (Ctrl+K)
• AI-powered navigation: describe any setting or action in natural language
• Single source of truth for all navigable UI elements (ui_tree.py)

PSM scan visualization

• Individual scan plot with draggable marker in contour tab
• Scan playback controls in Distribution tab
• Individual scan plot displayed as step histogram
• Bin plot with log scale and cursor snapping

PSM inversion and data processing

• Re-invert feature: rebuild CSV from raw .dat files with updated parameters
• Gaussian correction for 10 Hz PSM data
• Scan offset time correction for 10 Hz inversion
• Dynamic running average scan offset calculation (matches Inversion GUI)
• Apply dilution and polynomial correction to historical 10 Hz data
• Extract trailing concentrations for 1 Hz scans
• Preserve scan type in finalize_scan for correct 10 Hz flow calculation

other features

• Load multiple CSV files to fill time window gaps
• Cross-platform auto-start when Resume on Startup is enabled
• Auto-start simulators on config load with improved saving status feedback
• Windows exe build and auto-release via GitHub Actions

bug fixes

• Fix main plot empty when follow mode is off at startup (stale view range)
• Fix PSM scan/inversion broken by connect_async running on non-Qt thread
• Fix stale axes and curve leaks on device removal
• Fix stale port cache after device tab close
• Fix UI freeze when opening files/folders on Windows
• Fix averaging controls not disabled when menu opened after CSV load
• Fix re-inverted data not persisting to CSV
• Fix PSM contour tab UI issues on Windows
• Fix PSM single scan cursor playback freezing at fast speeds
• Fix pulse analysis dialog parent

UI improvements

• Refactor plot control panel
• Loading overlay with card-style container
• UI polish: text overflow elision, field order, legend labels, COM port read-only
• Persistent tooltip on manual port input field
• Port removed signal so COM port dialog refreshes on device unplug

dev / CI

• Fix test suite: broken CPC tests, slow test skipping, PyQt5 segfault on teardown
• Reduce CI costs: Linux-only runner, single Python version (3.11)
• Add CLAUDE.md project instructions
• Add pytest.ini to skip slow simulator tests by default

• fixed AFC set flow widget

logging (.log) changes:

• changed logging level to INFO to avoid spam (previously DEBUG)
• changed log filename to multilogger_log.log for clarity (previously debug.log)
• changed date format to '%Y-%m-%d %H:%M:%S' (previously '%m/%d/%Y %I:%M:%S %p')
