0.21.0

[0.21.0] - 2026-10-01

Added

• Clock picker for custom range times
• Download the chart as PNG image
• CSS and JS assets auto-minification at startup with web.minify_assets: true
• TV mode under Focus Mode
• Space Invaders: graphics settings and restart option
• tui: historical data charts

Changed

• The custom range picker uses one month calendar instead of two side-by-side
• Retained history now limits only which days can be picked
• Unused CSS/JS cleanup
• The dashboard now loads one trimmed Chart.js bundle instead of three scripts
• The dashboard paints sooner: Chart.js no longer blocks the first paint, and charts are
  built once the page is on screen
• The Inter font ships as WOFF2 (349 KB instead of 875 KB, same glyphs)
• Static assets are revalidated with an ETag instead of downloaded again on every visit;
  an unchanged server answers 304 Not Modified
• tui: UI/UX improvements

Fixed

• The Focus Mode bar ("Select graphs…", Hide gauges, Done, Cancel) is now translated
• Space Invaders: fixed game stability on firefox
• Layout shifts while the dashboard loads: the gauges, chart headers and sampling info no
  longer push the page down when they fill in
• A light-theme dashboard no longer shows a dark first frame; global.default_theme also
  applies before the config request finishes
• System Info no longer grades fans and voltages with temperature thresholds, and uptime refreshes
• System Info no longer stretches a lone section tab
• The remaining hard-coded dashboard strings are translated
• A custom range time inside a DST gap now shows the time that actually loads
• A corrupt record length in a tier file no longer allocates up to the whole ring before the read fails

0.20.3

[0.20.3] - 2026-09-29

Fixed

• Min/Max charts stopped drawing new data on short live windows (for example 5 minutes on a
  narrow screen or a list-layout card) whose history the server returned in bucketed form:
  live samples without extrema were appended as blank points and flagged "Min/Max unavailable".
  The dashboard now streams only onto native raw views and refreshes bucketed views instead
• Selecting a window without Min/Max (such as raw history or an empty refresh) no longer
  silently switches the rest of the session to Avg; the Min/Max choice returns as soon as a
  view supports it again

0.20.2

[0.20.2] - 2026-09-20

Fixed

• Avg/Min/Max availability flickering on raw history windows: clipping the right edge
  no longer certifies synthesized extrema, so native-resolution responses consistently
  stay data-only instead of depending on whether the lookahead scan saw a newer record
• Raw history windows no longer report "Min/Max unavailable" in detailed tooltips when
  the response never offered Min/Max aggregation

0.20.1

[0.20.1] - 2026-09-18

Added

• global.show_system_details (default false) gates the storage, network,
  connected-device and sensor inventory on the System Info page

Changed

• System info no longer collects or displays IP and MAC addresses

0.20.0

[0.20.0] - 2026-09-18

Added

• System info page with /api/system-info endpoint
• Persistent disk IDs from sysfs, stable disk selectors and kula_disk_info mappings (#46)
• kula disks helper to list available disks and partitions with their persistent IDs (#46)
• Live, Back, Forward and Zoom out navigation with shareable historical ranges
• Drag-selection, Ctrl+wheel and touch pan/pinch
• Keyboard navigation and a shared crosshair with timestamp pinning
• Min–Max bands and detailed history tooltips with exact timestamps and coverage
• Local/UTC display and optional Data/CSV controls in Customization

Changed

• Disk Prometheus device labels now use persistent IDs (#46)
• Smoother chart rendering and lower-memory history queries
• Custom and zoomed ranges, including device selections, stay frozen while live status updates
• Long live windows retain the selected history during refreshes and failures
• Zoom-in stops at 12 data points, excluding gaps, with a sampling-aware minimum duration
• Fresh installs default to Avg with straight, unfilled lines and one principal Min–Max band
• Grid/list changes preserve chart data and legend selections
• Tier naming unification
• Inspect feature improvements
• Implemented a unified rounding campaign while preserving full precision in storage and APIs
• UI performance improvements
• Aggregation optimization

Fixed

• Expired live sessions now return to login and cancel pending history loads
• Signing in restores the selected range without reloading the page
• Disk history and rates mixing physical drives when kernel device names change;
  old name-only history remains separate from new identified series
• History aggregation, bucket boundaries and coverage across storage tiers, collection gaps
  and missing metrics; older rollups remain approximate
• Avg/Min/Max controls hidden by legacy history: restore supported CPU, load, memory and
  swap extrema through read-time compatibility without rewriting tier files; unsupported
  extrema remain gaps, with availability notices and source details in tooltips and CSV exports
• History caching and point limits, including sub-second requests and concurrent updates
• Historical points, extrema and sensor identities lost during zoom, redraws or live updates;
  missing observations now retain line breaks and shaded gap indicators
• Slow history responses overwriting newer ranges or active zoom gestures
• Date-picker, Focus Mode, chart-label, localization and crosshair accessibility issues
• Crashes on WebSocket disconnects, short container IDs and malformed history, plus spurious
  WebSocket errors on logout
• Increased storage.tiers[].max_size now takes effect without discarding history;
  shrinking an existing tier still requires manual action
• fix: bound offscreen chart state and release split cards (#50)

Security

• Fixed login rate limiting that allowed targeted account lockout and global login denial
• Added an absolute session lifetime to prevent indefinite renewal

Thanks @hawkff @AtmanActive
