Changelog

What's new

• Added a dedicated Bandwidth Statistics window with 1H, 24H, 7D, 30D, and 1Y ranges so you can review short- and long-term bandwidth trends.
• Visualized download and upload timelines alongside top adapters and top apps, giving you a high-level and per-source view in one place.
• Kept statistics collection optional and off by default, with a separate app-statistics toggle for users who want deeper historical analysis.
• Introduced a built-in Speed Test you can launch from the menu bar icon context menu, using integrated M-Lab and Cloudflare providers.
• Showed detailed speed test results for download, upload, latency, and server information in a dedicated Speed Test window that remembers your last selected provider.
• Saved each completed speed test locally into a Speed Test History so you can compare results over time by date, provider, download, upload, and latency.

Other highlights

• Updated the app icon and added a matching menu bar icon option, with design credit to GitHub user JohnnyFireOne.
• Improved popup positioning so the NetFluss popover stays aware of screen edges and remains fully visible near screen borders.
• Refined total bandwidth handling for VPN and tunnel adapters so combined traffic summaries better reflect your actual routing setup.
• Expanded the right-click menu with entries for Bandwidth Statistics, Run Speed Test…, Try FileFluss, and project support links for quicker access to these actions.

What's new

• Added new menu bar icon styles: Standard, Unified pill, Dashboard, and Icon, so you can match NetFluss to your preferred menu bar look.
• Introduced separate color controls for the upload arrow, download arrow, upload number, and download number for more granular visual customization.
• Expanded icon choices in Icon mode and refined menu bar layout and spacing options to keep the status item clean and readable.
• Renamed the app branding to NetFluss across the app bundle, release assets, and README to align the product name consistently.

Improvements

• Greatly reduced CPU usage and energy impact in real-world usage, especially after opening and closing the popover.
• Reworked menu bar rendering, popup lifecycle handling, and background sampling so hidden UI and popup-only work do not stay active unnecessarily.
• Stabilized Preferences and About window teardown to avoid UI-related crashes while preserving the lighter runtime behavior.

Update checker

• Added an optional automatic GitHub update checker that runs once per day to notify you about new releases.
• Kept the original manual update check in the About window so you stay in control of when to look for updates.
• Linked update notifications directly to the latest GitHub release page for a clear path to download details and new builds.

What's new

• Added experimental UniFi Bandwidth Monitoring that tracks WAN download and upload rates from UniFi gateways (UDM, USG, UXG).
• Authenticates UniFi routers via the UniFi OS REST API, storing credentials securely in the macOS Keychain and supporting both UniFi OS and legacy controller setups.
• Added experimental OpenWrt Bandwidth Monitoring that shows WAN download and upload rates from OpenWrt routers.
• Connected to OpenWrt using the ubus JSON-RPC API with automatic session management, keeping router credentials stored securely in the macOS Keychain.
• Improved Fritz!Box support so NetFluss auto-detects the Fritz!Box router address from the default gateway, reducing manual configuration.
• Expanded menu bar layout options with a pinned unit so you can lock the display to KB/s, MB/s, or GB/s (bits or bytes) instead of auto-scaling.
• Added menu bar decimal controls so you can choose 0, 1, 2, or 3 fixed decimal places or let NetFluss decide automatically.
• Included Black as a new color option for upload and download labels in the menu bar.
• Fixed arrow alignment for proportional system fonts (System and Rounded) so arrows line up cleanly next to bandwidth values.
• Made the popover scrollable and resizable so it works better on smaller screens and with many active adapters.

Improvements

• Reduced CPU and energy usage by caching expensive operations: interface info (~30s), Wi‑Fi details (~5s), netstat (~3s), DNS checks (~10s), and router polling (~5s) instead of recalculating every tick.
• Reused shared system resources such as SCDynamicStore instead of recreating them each update, cutting overhead on every refresh.
• Cached PID-to-name lookups across netstat samples so NetFluss resolves process names less often while keeping Top Apps accurate.
• Cached the menu bar font and moved JSON decoding work out of the SwiftUI render path to keep UI updates lightweight.
• Reduced overall CPU wake-ups and background work to lower NetFluss energy impact on battery-powered Macs.

What's new

• Added experimental Fritz!Box Bandwidth Monitoring that shows total WAN download and upload rates from your Fritz!Box router directly in the NetFluss popover.
• Queried Fritz!Box bandwidth data via the official TR-064 API without requiring authentication for these metrics.
• Displayed bandwidth utilization with progress bars relative to your configured line speed, matching your DSL, cable, or fiber sync rates.
• Made the Fritz!Box router address configurable in Preferences → Fritz!Box Bandwidth, defaulting to fritz.box so you can adapt to custom network setups.
• Enabled editing of custom DNS presets after creation so you can update both the preset name and server addresses.
• Added a pencil icon next to each custom DNS preset in Preferences → DNS Switcher as the entry point for editing.

Improvements

• Reduced unnecessary UI refreshes triggered by Fritz!Box polling so the popover stays smoother and more efficient while bandwidth monitoring is active.
• Closed the popover automatically when you open Preferences to streamline the workflow and avoid overlapping windows.

What's new

• Switched DNS changes and Ethernet reconnects to use Touch ID when available instead of the admin password dialog, falling back to a password prompt when Touch ID is unavailable.
• Added a Touch ID toggle for DNS-related actions in Preferences → DNS Switcher so you control whether NetFluss asks for Touch ID or always uses the password dialog.

Bug fixes

• Made the preferences window resizable so it fits better on smaller screens.
• Documented a macOS and SwiftUI limitation where the resize cursor may not appear at the window edges, while confirming that dragging the edges still resizes the window correctly.

What's new

• Ensured the External IP shows IPv4 by default so dual-stack connections no longer default to IPv6 in the menu bar.
• Reduced external API calls for country code lookup by performing lookups only while the Connection Flow View is active.
• Added an IPv4/IPv6 preference for External IP under Preferences → Appearance → External IP so you control which address family NetFluss displays.

What's new

• Added a DNS Switcher so you switch DNS providers directly from the popover, with built-in presets for Cloudflare, Google, Quad9, and OpenDNS, plus support for custom presets.
• Made DNS changes a one-click action from the menu bar, prompting for your admin password when required, while keeping your chosen presets manageable from Preferences where you toggle them on or off and drag to reorder.
• Introduced App Filtering for Top Apps via Preferences → Top Apps → "Apps to Hide", listing all processes that used bandwidth in the last 60 seconds so you can hide noisy background items from the Top Apps view.
• Improved menu bar stability by using a fixed-width container so the status item no longer shifts as values change and the popover stays anchored in place.
• Fixed External IP display reliability by switching the lookup to ipwho.is with an api.ipify.org fallback so the external address appears consistently.

What's new

• Added a Connection Flow View with an optional IP display that shows the path from your Mac through the router and any active VPN tunnel to the internet, including a country flag for VPN exit nodes. Switch between classic list and flow view in Preferences.
• Introduced an Adapter Grace Period (3, 5, or 10 seconds) so adapter cards stay visible briefly after going idle, reducing flicker. Configure the grace period in Preferences.
• Added a Top Apps Grace Period (3, 5, or 10 seconds) that keeps recently active apps in the list for a short time after traffic stops, making the list more stable. Adjust the duration in Preferences.
• Added a Wi‑Fi detail popover accessible from the info button on the Wi‑Fi adapter card, showing Wi‑Fi standard, security, channel and width, RSSI, noise, SNR, ESSID and BSSID with copy support, and transmit rate.
• Linked a Buy Me a Coffee support option from the About window to make it easier to support ongoing NetFluss development.
