cgxsystem.library
=================

Changes for 42.1

- cybergraphics vblank interrupt handler is now only installed if at least
  one graphics card is configured for draggable screens
- fixed some problems with doublebuffered screen bitmaps

Changes for 42.0

- initial v4 release


CV64 driver
===========

Changes for 4.1

- fixed some blit/rectfill problems with double buffered screens
  (fixes problems with StormMesa 3.0 fullscreen mode)

Changes for 4.0

- initial release


CV3D driver
===========

Changes for 4.1

- To workaround some problems with Scalos and NewIcons in conjunction
  with the BITMAPCACHE option, bitmaps with a width < 64 pixels 
  are not cached anymore. This is added as a temporary workaround and
  will be changed in a future release.
- Fixed another problem with doublebuffer bitmap support. When 
  BITMAPCACHE was enabled, the 2nd buffer bitmap was not properly
  loaded into the framebuffer which could result in a buffer
  staying completely black
- video stream support is not buffered anymore when the card is 
  configured for ZorroIII mode
- fixed some blit/rect fill problems with double buffered screens
  (fixes problems with StormMesa 3.0 fullscreen mode)

Changes for 4.0

- initial release


3DLabs drivers
==============

Changes for 4.1

- To workaround some problems with Scalos and NewIcons in conjunction
  with the BITMAPCACHE option, bitmaps with a width < 64 pixels 
  are not cached anymore. This is added as a temporary workaround and
  will be changed in a future release.
- The CVisionPPC now only works for CVisionPPC card. You need to
  install the BVisionPPC driver for BVisionPPC
- setting of h/v sync polarity now works properly. If a resolution 
  looks differently with the new driver, check the sync polarity 
  setting for this mode (if it is set to positive, you can switch it
  to negative to get the same result as before)
- added support for new BVisionPPC card and different RAM types used
  with latest CVisionPPC cards
- fixed some blit/rectfill problems with double buffered screens
  (fixes problems with StormMesa 3.0 fullscreen mode)

Changes for 4.0

- initial release


Cirrus Logic drivers
====================

Changes for 4.1

- fixed some blit/rect fill problems with double buffered screens
  (fixes problems with StormMesa 3.0 fullscreen mode)
- fixed bug for blits that were higher than 1024 lines with GD5434
  chip (PiccoSD64, Pixel64)
- BITMAPCACHE tooltype option now works properly
- driver now properly recalculates the exact pixelclock
  -> CGXMode now gets exact pixelclock results when pressing the x
  key on the testmode screen
- blitter rectangle copy method activated for 24bit 3bpp modes with
  old CL (non 5446) cards (PicassoII(+)/Spectrum/Piccolo)
- fixed problems with GD5434(PiccoSD64,Pixel64) and >= 85Mhz 8bit
  displaymodes
- PicassoIV driver now works with resolutions that use exactly 85MHz
  dotclock

Changes for 4.0

- initial v4 release


Symbios Logic drivers
=====================

Changes for 4.1

- added Altais/DraCo support
- To workaround some problems with Scalos and NewIcons in conjunction
  with the BITMAPCACHE option, bitmaps with a width < 64 pixels 
  are not cached anymore. This is added as a temporary workaround and
  will be changed in a future release.
- added bitblit acceleration for some occasionally used minterms
- driver now properly recalculates the exact pixelclock
  -> CGXMode now gets exact pixelclock results when pressing the x
  key on the testmode screen
- BITMAPCACHE tooltype option now works properly

Changes for 4.0

- initial v4 release


CGXMode
=======

Changes for 4.1

- Change of H/VSync polarity is now properly updated on the testscreen
- removed some obsolete debug output when pressing help key
- max pixelclock in 8bit is now properly limited to graphics card maxclock
  maximum pixclock slider value is now reset when scan depth is changed
- Changes to the H/VSync polarity are now properly updated in the edit
  resolution window when they were changed on the test screen
- clone now directly opens the edit window and reinserts the mode
  after the related depth and not at the end of the list when the
  copied mode is accepted.
- new now directly opens the edit window and inserts the mode
  after the last mode with the same depth and not at the end of the
  list.
