v0.3.1

Changed

• Settings shows the MQTT Scope version at the bottom.
• No menu bar on Linux and Windows: Check for updates, Show log file and Open data folder are at the bottom of Settings, next to the version. Keyboard shortcuts work as before.
• Settings → Keyboard also lists the shortcuts that can't be changed (zoom, full screen, developer tools, quit).
• Settings fits small windows: the middle scrolls, and Save stays in view.

Removed

• The About dialog on Linux and Windows (the version is in Settings).

What's Changed

• Settings shows the version; no menu bar on Linux and Windows by @ToRexZ in #5
• MQTT Scope 0.3.1 by @ToRexZ in #6

Full Changelog: v0.3.0...v0.3.1

v0.3.0

Added

• Update notice. MQTT Scope checks GitHub for a newer release at startup and every 6 hours. When there is one, an Update x.y.z button appears in the top bar and opens a panel with the release notes. Later closes the panel; Skip this version hides that version until a newer one is out. Turn the automatic checks off in Settings → General → Check for updates.
• Help → Check for Updates… checks right away, tells you when you are on the latest version or the check failed, and un-skips a skipped version.
• Self-update. The AppImage and the Windows installer download the update on request (Download update) and install it with Restart to update (which asks first if brokers are connected), or when you quit. Tar.gz, Windows portable and macOS builds open the release page instead; Arch Linux packages show a command to copy.
• Restart to update shows an Installing MQTT Scope x.y.z dialog with a moving progress bar in every main window until the app closes. On Windows the installer's own window then shows the install's progress, and MQTT Scope opens again in front, about half a minute in all; the AppImage restarts into the new version within seconds.
• Releases now include PKGBUILD and mqtt-scope.desktop for Arch Linux, so makepkg -si works from the release files alone.
• After a self-update the AppImage has the new version in its file name: rename it (e.g. MQTT-Scope.AppImage) to keep launchers working.
• The AppImage shows the MQTT Scope icon in the dock and app grid on GNOME (Ubuntu) instead of a generic one. For that it adds a menu entry when it first starts, which follows self-updates and disappears from the menus once the AppImage is deleted (none is added when the Arch package or an AppImage manager already provides one).

What's Changed

• AUR package 0.2.1 by @ToRexZ in #3
• Update notice and auto-update; MQTT Scope 0.3.0 by @ToRexZ in #4

Full Changelog: v0.2.1...v0.3.0

v0.2.1

Added

• Release files come with signed GitHub build attestations: check a download with gh attestation verify <file> --repo ToRexZ/mqtt-scope.

Fixed

• Narrow windows. Tiling window managers can make the window narrower than its 900 px minimum, which cut off the inspector, publisher and top bar. Below that width the topic tree now sits above the inspector (drag the bar between them to resize; the height is remembered), the top bar wraps, and a narrow but tall inspector shows the message history below the message.
• The inspector's topic no longer collapses into a column of single characters when the inspector is narrow; its buttons wrap below it instead.
• A remembered tree width no longer squeezes the inspector after the window gets smaller.

What's Changed

• Keep the inspector topic readable in a narrow window by @ToRexZ in #1
• Narrow-window layout; MQTT Scope 0.2.1 by @ToRexZ in #2

New Contributors

• @ToRexZ made their first contribution in #1

v0.2.0

Added

• Plot tabs. Organise plots in named tabs (e.g. Safety, Motion), each with its own plots and arrangement. Tabs are saved automatically; double-click to rename, right-click (or ⋯) to duplicate, delete, or export/import a tab as a .json file to share. Data is collected for every tab, so switching tabs shows the full timeline. Each tab shows how many plots it holds.
• Lichtblick-style plot layout. Plots fill the tab. Drag a plot by its title onto the edge of another plot to put it beside, above or below it, onto its middle to swap them, or onto another tab to move it there (Esc cancels). Drag the gaps between plots to resize them (double-click a gap to even them out). Arrange lays them out in rows again. A plot never gets so small that its lanes overlap; below that the tab scrolls.
• State transitions plots. Switch a plot between Lines and States. In a State transitions plot every series is a labelled lane that changes colour when its value changes, with the values written in and the current value next to the label. Plots made only of true/false values start in this mode.
• Zoom. Drag across a plot to zoom into that time range (all plots in the tab follow); drag a box to zoom into a value range as well. Reset view on each zoomed plot (and in the toolbar), double-click or Esc go back to the live view.
• Vertical lines at timestamps on plots, like Lichtblick's time grid (on by default; plot settings → X axis to turn them off for a plot). They are drawn over state lanes so they stay visible on the data.
• Pop-out plots. Open a plot in its own window, to put it on another screen; it keeps plotting live and has its own time window, freeze and zoom.
• Full screen for a single plot.
• Plot settings panel for the selected plot, laid out like Lichtblick's: title, plot type, time window, legend and values, y-axis range, time grid, and per series visibility, label (alias), colour picker or palette colour, display style (line, line and points, steps, state lane) and line width. The panel can be hidden and resized.
• Synced time bar. Hovering one plot moves the time bar on every plot of the tab, and the legends show the values at that moment.
• Rebindable keyboard shortcuts in Settings → Keyboard (clashes are flagged; the menu shows the current keys).
• Space holds and releases the inspector's message, or freezes the plots on the Plots tab. Ctrl+R clears received messages and restarts the plot timelines (pop-out windows too) without disconnecting.
• Setting: clicking a topic in the tree also expands it one level.
• Website at https://torexz.github.io/mqtt-scope/ and an Arch Linux package (packaging/aur, mqtt-scope-bin).

Changed

• Icons are monochrome line icons that follow the theme.
• Plots are saved in plotTabs.json. plots.json keeps the tab on screen in the 0.1 format, so 0.1.0 still finds its plots; plots changed by 0.1.0 after an upgrade come back as a Plots (older version) tab instead of being lost. Plots saved by 0.1.0 open as a tab.
• Each window keeps its own plot tab on screen; changes made in one window appear in the others.
• Plotting is much lighter at high message rates and with long histories (about 0.003 ms per message per plotted value, and a few ms per redraw at 100,000 points). All plotted data together is capped at roughly 150 MB.
• Space and Enter press a button reached with the keyboard instead of triggering a shortcut.

Fixed

• Freeze now also holds plots whose time window is All, and legends show the values at the moment of freezing rather than newer ones.
