ergohaven/entropy v0.6.0

Entropy v0.6.0

on GitHub

v0.6.0

Main Features

• Added support for Ergohaven RMK keyboards using the Rynk protocol over USB and Bluetooth, alongside existing Vial devices: keymaps, encoders, macros, Tap Dance, Combos, Key Overrides, layer names, module settings, unlock, and Matrix Tester follow the capabilities reported by the firmware
• Added Rynk .entlayout import/export with compatibility and loss checks before writing, read-only headless backup, and time, keyboard layout, and media integration for compatible Qube displays
• Added SM62 resident application layouts on compatible firmware, including up to 100 stored profiles, resident inventory/readback, reconnect synchronization, and guarded complete backups before resident-layout imports
• Added SM62 display configuration and host previews for clocks, keymaps, media players, and standby animation, with per-device/half controls, shared-setting confirmation, and firmware-matched artwork
• Expanded macros with modifier combinations, firmware-supported RMK Tap-Hold and Universal actions, complete-slot copy/paste with Undo, and capacity checks against the active firmware storage codec
• Added a Linux system-tray icon with Open and Quit, background startup, and a minimized-window fallback when the desktop has no tray host
• Added a choice of stable releases or published Rynk development builds for application updates, plus separate opt-in macOS notifications for application and firmware updates

Improvements

• Added persistent Universal Symbols ANSI/ISO geometry and capability-gated universal numero support for compatible Vial/RMK and Rynk firmware, with negotiated native v1/v2 compatibility rather than assuming a codec
• Added Qube display brightness, background, and text-size controls when the firmware exposes them; retained the selected-mode workflow for pointing-module settings
• Extended device backups to preserve confirmed layer/connection colors, LED brightness and timeout, and compatible RGBLight or VialRGB settings, while leaving omitted settings in older backups unchanged
• Allowed --export-layout to borrow a running Entropy instance's connection read-only on Linux and macOS, with bounded requests, cancellation, and complete-snapshot checks; Windows still requires the other instance to be closed
• Added desktop-specific Linux Text Expander status and setup guidance, confirmed GNOME input-source replacement/restoration, KDE input-method guidance, and declarative NixOS setup without taking over the user's input method
• Improved USB discovery while Bluetooth devices are connected, stable device-list ordering, and reconnection to the last explicitly selected unambiguous keyboard
• Reduced idle work with event-driven KDE focus/layout tracking, cached complete Linux USB scans, deadline-driven host bridges, and lower background repaint activity
• Bounded preview/texture caches, decoded animation frames on demand, and deferred the Windows graphics window for minimized startup; this is not a measured process-memory saving
• Updated the GUI integration to egui/eframe 0.37, kept module/display controls within the established compact settings layout, and improved Russian picker hints and About-value tooltips
• Retained stable project-certificate macOS signing and the DMG Applications link, added bounded transient DMG verification retries, improved Nix media-tool availability, and hardened pinned dependency downloads and source-bound CI coverage reuse

Fixes

• Preserved Macropad layer rename drafts across metadata/profile changes, wrote Default layer names through confirmed firmware SET/GET, and retained explicitly cleared or firmware-provided names across reconnect and export
• Scoped Display settings and probes to the selected device's actual firmware, preventing unrelated K:04 settings from being interpreted as Macropad or SM62 display controls
• Preserved background device owners and fresh desktop feedback through USB hotplug, partial inventory, keyboard takeover, and successful empty macOS USB enumeration
• Restored and read back Vial macro bytecode during layout import, including deferred unlock/HID return, without replacing confirmed local macros after failed writes
• Reported failed and partial layout imports with their actual errors and successfully written sections, and refused incomplete or uncertain backups instead of exporting defaults
• Reconciled SM62 resident STORE/QUERY results with authoritative FULL readback, fenced stale owner/library results, and kept existing backups intact when export or publication fails
• Kept pending device edits and Text Expander saves progressing while hidden, and connected keyboards during tray-only startup without requiring a visible graphics frame
• Corrected Rynk bulk paging, USB reply draining, Bluetooth device deduplication, reconnect handling, and Rynk-specific firmware asset selection; pipelined Bluetooth reads and cached verified definitions
• Allowed momentary-layer replacements in RMK Key Overrides, including supported K:04 Vial firmware, while retaining QMK restrictions and firmware capability gates
• Preserved native Tap-Hold retargeting, made macro Bluetooth/layer choices available in both picker views, scrolled modifier choices with the key list, and retained the original Alt captions and side-specific encoded values
• Explained macro text normalization and unsupported characters, rendered escapes in formatted translations, and directed macOS Text Expander setup to the missing permission before offering Restart capture
• Retired Macropad-only application templates from SM62 without deleting device records or automatically creating new profiles

Verification

• Exact release source: fc1e78e2a58806910faf4296cb0f22855389e2c9. Build passed all eight jobs and Nix passed all four jobs.
• Apple Silicon and Intel each passed the full native macOS nextest suite: 2090 tests, 23 source-declared skips, all five required lifecycle/HID regressions and no retries. The selected Windows suites passed 78 unique tests; this is not a full Windows test-suite claim.
• Release build passed all four platform builders and its draft-publishing job. Both DMGs passed native certificate/signature, read-only mounted-image and Applications-link checks against the stable project certificate. Package versions and actual CPU architectures were checked from the downloaded binaries.
• All four binary archives and both signing-proof archives matched their producing run and SHA-256. The four binaries plus SHA256SUMS.txt were downloaded from the private draft and matched the verified original bytes.
• The actual release AppImage was launched under isolated Xvfb, a private D-Bus session and software rendering. Its device-access/udev setup window rendered successfully. No udev rules were installed and no keyboard actions were performed; this establishes GUI startup, not physical-device configuration or hardware compatibility.
• No new physical-keyboard, installed-app macOS/Windows launch or OS permission-retention acceptance is claimed. Self-signed DMG integrity is not Apple notarization or installed-app functional acceptance.

Downloads

• Linux x86_64: entropy-v0.6.0-x86_64.AppImage; make it executable and run it. This release uses the pinned container packaging path, not the Ubuntu build-host sysroot. The actual AppImage executable requires GLIBC 2.35. The extracted ELF was independently matched to this AppImage and its embedded desktop version is 0.6.0. Native .deb, .rpm, and Arch targets remain available from source but are not part of this release's attachment set.
• Windows x86_64: entropy-v0.6.0-windows-x86_64.exe; portable executable, requiring Microsoft Visual C++ v14 x64 Redistributable. FileVersion and ProductVersion are 0.6.0. It is not Authenticode-signed and SmartScreen may warn.
• macOS: entropy-v0.6.0-macos-arm64.dmg for Apple Silicon and entropy-v0.6.0-macos-x86_64.dmg for Intel. Actual Mach-O minimum versions are macOS 11.0 for ARM64 and 10.15 for Intel; both bundle versions are 0.6.0. Use these stable project self-signed packages, not ad-hoc development .app.zip files. This is not Apple Developer ID signing or notarization. Open the DMG, drag Entropy to Applications, eject it, and launch the installed app; if blocked, use System Settings → Privacy & Security → Open Anyway. Download from GitHub rather than relying on Telegram-delivered quarantine behavior. Permission retention across distinct signed updates and installed user-machine launch were not verified by the signing checks.
• SHA256SUMS.txt contains SHA-256 checksums for all four downloads.

Back up the keyboard before updating firmware. Rynk requires compatible Ergohaven firmware; Universal Symbols, Qube controls, and SM62 resident layouts are capability-gated, not universal promises for every device. Resident backups use fully flushed, no-clobber file publication. Unix also syncs the captured newly created directory chain; Windows intentionally uses file-level flushes without UAC/elevation and does not guarantee survival of a newly created backup path after sudden power loss or an OS crash. Reported filesystem errors refuse import on either platform. This is not power-loss certification.

The v0.5.0 Windows (#191) and macOS (#195) asset refreshes are historical, partial-platform updates already described in that release. Their fixes remain in this source, but their previous validation is not new v0.6.0 build evidence.
