* Changes in VICE 3.3
=====================

This release stabilizes and introduces the GTK3 UI as the primary user interface 
for all major ports. For "lesser" platforms we still have the SDL1/SDL2 based 
interface. All other user interfaces have been removed. RIP

We are still looking for dedicated maintainers for the Windows- and macOS ports,
if you want to help improving these and/or want to provide binaries, please get
in touch.

** General
----------

- Old, unmaintained, ports removed:
  * MacOS Cocoa: use SDL or Gtk3
  * WinVice: use SDL or Gtk3
  * BeOS/Haiku: use SDL
  * AmigaOS: use SDL
  * Unix Xaw: use SDL or Gtk3
  * Unix Gtk2: use SDL or Gtk3
  * OS/2: use SDL

- Fix building against external ffmpeg >= 4.0

- Fix errors in multi-SID code

- added single SNES pad emulation (compatible to Ninjas adapter/TrapThem64)

- Make VICE much faster by using -O3 vs -O2

- add a slot number before the literal name of a game-controller, which is less 
  confusing when more than one controller of the same type is used

- fix parsing of the commandline with -config first

- added dutch to list of keyboard mappings

  
** Unix fixes
-------------

- the sleep function was not handling timer overflows properly, which happens
  every 4 seconds on a 32bit machine with nanosleep()

- Split ReSID resource into 6581/8580-specific resources (passthrough/gain/bias)
- various envelope generator fixes
- use different timing on 6581/8580 for noise register reset when testbit is set

  warp and pause/advance frame

- Add popup menu to the joystick widget to allow swapping joysticks and
  userport joysticks, add shortcut menu item to joystick settings UI

- Add cartridge content preview to the cart-attach dialog
  (x64/x64sc/xscpu64/x128)

- Dynamically load CBM font

  in all ports

- Terminal- or GUI based monitor can be selected at runtime in all ports

- introduced new VICE logo provided by Bjoern Odendahl (thanks!)

- fix assignment of user keymaps


** SDL UI
---------

- Add toggle button in x128 for the Go64Mode

- ignore 'dotfiles' in the fileselector on *nix

- added browsing inside disk and tape images.

- added pageup/pagedown/home/end key mappings, and support them in the menus, 
  file-selector and text viewer

- Terminal- or UI based monitor can be selected at runtime in all ports

- added a hack to get rid of spurious keyup/keydown events after switching 
  from/to fullscreen
  
- generate suitable fonts for the ui at startup, use some custom gfx for the ui. 
  fixes the problem that the ui chars will screw up when the user selects a 
  japanese chargen :)
  
- when changing color- or crt emulation settings, print a color matrix on screen 
  and update the resources in realtime
  
- UI cosmetics:
  - fix slider length, use custom chars for slider
  - make screen all black before entering the UI
  - added basic default window icon
  - fix display of literal key names for SDL2

- major rework of SDL2 video renderer to work natively with all supported
  graphics acceleration technologies (OpenGL ES, DX11, Metal, etc). Fullscreen
  support and resized windows now preserve aspect ratio properly on any screen
  size.

- SDL2 now respects "GL" filter mode. As a bonus it does so even when the
  renderer is not OpenGL.


** VSID (Gtk3)
--------------

- Add drag'n'drop support
- Add HVSC support:
    * Support SLDB
