Whisker 0.9.2

A new look, profiles, and a fix for Logitech mice on a Unifying
receiver.

New

• New design. A fixed 800 x 600 window with its own title bar, a
  status bar for connection and battery, sharp controls, Inter and
  JetBrains Mono. Every page is laid out anew. About is a tab of
  Settings.
• Profiles. A profile is a named button layout with its macros.
  Make, copy, rename and delete them on the Profiles page; switch
  there, on Overview or from the tray menu. Each mouse has its own
  profiles.
• Profiles by app. A profile may name a program and works while
  that program is in focus. Not available under Wayland.
• Export and import. Write the active profile or all of them to a
  file and read them back, also on another computer.
• Several mice. Whisker remembers every mouse you have chosen and
  switches to one when it is connected, or when the current one is
  gone.
• Text mode. The >_ TUI button in the title bar, or F10, draws
  the whole window as a terminal screen. Keys 1-9 open the pages.
• Buttons page. The mouse is a 3D drawing built from the button
  layout of your model: side, top and grid buttons, tilt wheel, thumb
  wheel.
• Tray icon. The Whisker logo fills with the battery charge: green,
  amber, red; blue while charging.
• Effects. Background texture and animations, both switchable under
  Settings → Appearance → Effects.

Fixed

• Logitech mice on a Unifying receiver could lose their name and
  battery and flap between online and asleep. The driver took the reply
  to the previous request for the current one.
• A silent non-mouse device on a Logitech receiver could be opened as a
  mouse.

Changed

• Themes are Dark, Light, Tokyo Night and Dracula. A removed theme
  falls back to the system one.
• The language is chosen under Settings → General.
• Pages marked PRO preview Whisker Pro. They do nothing here.

Whisker 0.9.1

Fixes from the first bug reports, and an easier way to send the next ones.

Fixed

• "Change mouse" froze the window for seconds with several wireless
  receivers connected (#1). The dialog now opens at once and fills in
  when the mice are found. Thanks to @therealMKD for the report and the
  fix (#5).
• Error in the Windows event log on exit (0xc000000d, #1): closing
  Whisker with its window open ended with an application error. Also
  fixed in #5.
• The suggested catalogue entry in a mouse report named the receiver
  ("USB Receiver") instead of the mouse.

Changed

• Tray icon: the window opens on a double click, not on a single
  one (#6). The tooltip still shows the battery.
• Logitech M510 is listed as supported (#4).

New: reporting problems

• Diagnostic log. Whisker keeps a small log on your computer:
  start-up, mice found, what the driver did, crashes and hangs. Open it
  under Settings → Mouse → Diagnostics → Show log. After a crash or a
  hang Whisker offers it on the next start.
• Send. The mouse report (About → Help add your mouse) and the log
  can be sent to the developers with one click. You see the whole text
  first, and nothing is ever sent without that click. You get a report
  ID to quote in a GitHub issue.
• Logitech mice: the report now lists the HID++ features of the
  mouse and whether it runs its onboard profile (#2).

The log holds no serial numbers, Bluetooth names, key presses or
clicks. Sent reports are kept for 12 months. See Privacy in the README.

Whisker 0.9.0

The first public release of Whisker, a lightweight control app for
gaming mice. One small native program instead of a heavy vendor suite:
under 1 MB on Windows, no account, no telemetry.

What it does

• Battery in the window and the tray, with a runtime estimate.
• DPI stages with colours and a quick switch.
• Report rate, debounce, lift-off distance, sleep timer, plus a live
  measurement of the real report rate.
• Lighting effects, brightness, speed and direction.
• Button remapping and macros.
• Statistics for any mouse: clicks, wheel, distance, battery history.
• 9 colour themes or the system one, 13 languages.
• Daily update check (can be turned off); updates are signed and
  verified before they install.
