2.6 (2023-01-18)

Fix time-dependent effects (text fade-out, WASD acceleration) becoming jerky on Windows when the system has been running for more than two days.
Can now specify additional speed multiplier that is used for all movement operations when the scene's unit system is set to 'None'.

2.5 (2022-07-17)

Fix regression issue preventing camera panning when camera locked to view.
Can now specify which modifier key performs which action.
- This introduces a new default behavior where now Alt increases precision (i.e. causes speed decrease) while Ctrl engages alternative behavior (i.e. FOV-change using mouse wheel) in accordance with how it works everywhere else in Blender.
Can now specify modifier key effect strength (speed increase/decrease).
Pan sensitivity is now decreased automatically depending on focal length when it is greater than 50mm.
Removed some confusing modifier key combinations.
Added undo support.

Fixed movement option "Strafe left/right and rappel".
Improve support for using a mouse button as addon shortcut.
- Interpret bindings even when too many buttons are pressed.
  - Bindings with two buttons are chosen over bindings with a single button.
  - Thereafter, bindings further up the list are chosen over bindings further down the list.
  - Added up/down buttons to change order of bindings.
Automatic pivot relocation now defaults to being enabled.
Minimum supported Blender version increased from 2.92 to 2.93.

Added option to invert X/Y/Z mouse strafing directions.
Added option to align WASD up/down movement direction with global Z-axis instead of the view's Z-axis.
Added option to apply gear multiplier to WASD move speed.
Added option to apply gear multiplier to scroll wheel move distance.
Added option to configure when pivot adjustment ignores backfaces.
Added support for operator key binding to coincide with mouse buttons.
Added support for binding any combination of two mouse buttons.
Changed toggling of automatic pivot relocation to be triggered with Shift + C instead of by holding C for a second. (Usability)
Loading camera state now highlights the crosshair while the key is held.
Rolling the camera now respects holding Ctrl and Alt for reduced sensitivity.
Fixed angle display. (Blender uses 72mm sensor width for the 3D View instead of the standard 36mm used in Cameras for unknown reasons.)
Fixed behavior for cameras with Axis-Angle and non-XYZ Euler rotation modes.
Operator will now clean up its draw handler on error.

Camera save states now also save and load 3D View projection mode (perspective/orthographic).
Fixed a typo which broke panning when the invert mouse option was disabled.
Changing view angle with the mouse wheel now displays change on screen for a moment.
- Allow to set which aspect of view angle to control, i.e. horizontal view angle, vertical view angle or focal length in the addon preferences.
- Works for cameras, too.
Changing view angle with mouse wheel is now on Alt + mouse wheel to be in line with Alt reducing pan sensitivity being an interest in high zoom situations.
- Using Alt to lower pan speed will now lower the pan angle further depending on zoom level.
- Just mouse wheel can now change mouse strafe speed if set instead of moving the camera in addon preferences.
Can now configure up to 7 mouse strafe speed multipliers which can be cycled through by pressing G or Shift+G.
Holding the Relocate Pivot key to disable automatic pivot relocation will no longer cause a pivot relocation.
Fixed toggling automic pivot relocation by holding the Relocate Pivot key not being saved in the addon preferences when closing Blender.
Added option to load camera state after pressing a key instead of having to quickly tap a number key twice.
Added option to prevent the loading of camera states from changing the FOV.
Added option to invert mouse horizontal movement.
Addon now correctly registers under view3d category of addons (instead of view_3d).

Changed compatible Blender version to 2.92.0.
Updated ray casting to work with Blender 2.91 and later.
Removed some confusing, needlessly complicated settings.
Fixed occasional sudden jerky mouse movement. (Caused by Blender's cursor_warp glitch)
Fixed stuttery movement caused by missing INBETWEEN_MOUSEMOVE events.
Fixed unrelated key-presses passing through.
Added option to customize keys.
Added save states. (See README)
Crosshair now draws in yellow when trying to manually relocate pivot while automatic pivot relocation is enabled.
Holding relocate pivot key for one second now toggles automatic pivot relocation.

Pressing C to adjust pivot distance now ignores backfaces when backface culling is enabled in viewport settings.
Added camera roll mouse action. Can press R to reset roll.
Mouse strafing now remains active while at least one mouse button is still pressed, regardless of whether strafing key was released.
Addon now cooperates with "Lock camera to view" and "Local camera" settings.
Improved ergonomics of mouse acceleration.
package.bat now creates Linux-compatible archives.
Ctrl and Alt now affect strafe speed and pan sensitivity, respectively. Hold both to greatly reduce strafe speed.
Quad views are now somewhat supported. Blender seems to have a slew of its own bugs with them.
The scroll wheel can now be configured to change the field of view.
Can now set strafe-mode to be toggleable instead of hold-to-strafe.
