Changelog

Every version below matches a GitHub release with a downloadable .streamDeckPlugin. Generated from the repo’s CHANGELOG.md; do not edit this page by hand.

One entry per version. Tagged versions are published as GitHub releases; the Elgato Marketplace listing is a separate track.

1.1.9.0 - 2026-07-05

• Fixed the key sparkline clipping the bottom edge. The strip sat too low, so at a session low the line and its end dot were scissored by the key edge with no margin beneath. Moved the strip up (now y 120-134) so the line and the r=5 dot always clear the edge. Regenerated the marketing and docs images to match.

1.1.8.0 - 2026-07-05

• Meets the current Marketplace intake requirements (surfaced in the live Maker Console): manifest SDKVersion 3 and minimum Stream Deck app 6.9. The plugin now requires Stream Deck software 6.9 or later.
• Upgraded the runtime SDK from @elgato/streamdeck 1.4.1 to 2.1.0, which SDKVersion 3 requires. Migrated the property-inspector messaging off the removed streamDeck.ui.current onto streamDeck.ui, and moved the JsonValue/log-level imports to their new homes. Same behavior: all unit, e2e (harness, resilience, gadget, dead-fallback, load), and live-load checks pass, and the poller/render/status paths are unchanged.
• The plugin URL and the docs links now point at the documentation site (docs.slawrensen.com/hwinfo-streamdeck) instead of the raw GitHub repo.

1.1.7.0 - 2026-07-05

• Copy pass over everything a user reads, ahead of the Marketplace submission: manifest description, settings-panel text, status-screen and probe wording, README and docs. Plain punctuation throughout. No functional changes.
• New icons across the board: the app, category, and action icons now show what the plugin actually renders (a key face with a value and sparkline; a knob for the dial action) instead of a radial gauge it never draws.
• Repo: added npm run release:validate (lint, typecheck, tests, plus a copy/manifest/asset/version validator).

1.1.6.0 - 2026-07-05

• Sparklines now persist across page changes. The recent-history graph used to reset to empty every time a key reappeared (switching pages, waking the machine, the app reconnecting) and had to rebuild from scratch. History now lives with the poller and survives those, so switching away and back keeps the graph drawn. It also survives a °C/°F toggle now (same data, just relabelled), and a frozen HWiNFO no longer flattens the line; it holds its last real shape. (A graph on a page you haven’t viewed in a while still rebuilds, and fills at HWiNFO’s own update rate.)
• Redesigned the status screens (Start HWiNFO, Shared Memory off, Not updating, etc.) to be calmer and OLED-friendly: a true-black background instead of dark grey, two lines of soft-white text instead of three lines of hard white. Same guidance, much less glare.

1.1.5.0 - 2026-07-05

• Theme gallery: the “Deck default” chip is now structurally distinct from the preset it resolves to. It keeps its truthful resolved-palette face but wears a dashed accent border and a small link/follow badge, so it can never be mistaken for the Void (or any) preset chip at a glance, even when the deck theme it follows happens to render an identical palette. (v1.1.3/v1.1.4 tried text-only cues that still failed the eye.)
• Fixed a data-source fallback bug: when free HWiNFO disables shared memory after 12 hours it leaves the named mapping behind with a “DEAD” marker. The reader now validates that marker at open time, so “auto” mode correctly falls back to the Gadget registry instead of getting stuck on the “Shared Memory off” screen, and a shared-memory upgrade probe no longer closes a working gadget provider for the dead mapping. (New e2e:dead-fallback regression.)
• Fixed the sensor picker silently replacing your saved sensor: pressing Enter with the picker open but no search text typed used to select the first sensor in the list. It now leaves the current selection untouched.
• The dial’s “HWiNFO stalled” touchscreen text now says “check Gadget” when the dial is reading from the Gadget registry, matching the key screen and PI hint instead of always pointing at Shared Memory.

1.1.4.0 - 2026-07-04

• Theme gallery: the “Deck default” chip face now reads “auto” (in the resolved theme’s colors) instead of a sample value, so it no longer looks like a duplicate of the theme it currently resolves to.

1.1.3.0 - 2026-07-04

• Fixed the theme gallery layout: the longer “Deck default” label introduced in 1.1.2.0 blew its grid column wide (CSS grid min-width:auto). Chips are equal-width again; the resolved deck theme now appears in the help line under the gallery (“currently Void”) and in the chip tooltip.

1.1.2.0 - 2026-07-04

• Theme system truthfulness: the settings panel’s “Deck default” chip now shows the plugin’s actual resolved deck theme (labelled with its name, e.g. “Deck default · Void”) instead of guessing from raw global settings, and updates live when the deck-wide theme changes. Added help text making the precedence rule explicit: a per-key theme always wins; the Advanced “Deck theme” only affects keys set to Deck default.
• Fixed: an empty or invalid stored deck theme could permanently block the legacy-migration default while silently failing to apply; the migration can no longer overwrite a theme the user picked concurrently.
• The effective deck theme is now logged at startup and on every change.

1.1.1.0 - 2026-07-04

• Hardening: the plugin now watches its parent process and exits if the Stream Deck app dies without cleaning up (hard-crash scenario found during competitive benchmarking; previously the poller could keep the process alive with nobody to render for; normal operation already relied on the app’s job object). No functional changes.

1.1.0.0 - 2026-07-04 (first tagged build)

The baseline feature set. Tag: v1.1.0.

Features

• Live HWiNFO sensor readings on Stream Deck keys: value, unit, custom label, sparkline history, stat modes (current/min/max/avg; a key press cycles).
• Stream Deck + dial/touchscreen action: live value with session min/max and a range bar; rotate to switch readings, push to reset session stats, touch to cycle stat modes.
• Seven display themes (per key or deck-wide) with sensor-type accent colors and aviation-style alerting: amber/black at warn, red/white at critical. Alert colors are global and never themed.
• Searchable sensor picker in the settings panel with live values for all ~500+ readings, grouped by source.
• Dual data source with auto-fallback: HWiNFO Shared Memory (full stats) preferred, Gadget registry (free version, no 12-hour limit) as fallback, automatic upgrade back to shared memory when it returns.
• Resilient status screens for every failure mode: HWiNFO not running, Shared Memory disabled or expired, privilege mismatch (with the concrete fix), Gadget reporting enabled but no sensors ticked, stale data.
• First-run setup guide inside the settings panel.

Performance (measured, see PERF.md)

• Incremental shared-memory decoder: ~6 µs and near-zero allocation per poll tick for ~516 readings (up to 62× faster than the naive decode).
• ~0.07 % average CPU with a 12-key live page at a 1-second poll.
• Memory-stable under a 35-minute soak (RSS slope negative); the plugin process exits cleanly when Stream Deck stops and idles when no keys are visible.

Notes

• Requires HWiNFO (free or Pro) with Shared Memory Support or Gadget reporting enabled. Windows x64 only (Windows-on-ARM shows a clear unsupported-platform screen).
