 doc/Makefile changed to have the man pages uncompressed in the distribution.
 GeForce support in nv3.c.
 Matrox G450 driver (called g400.c).
 ATI Rage 128 driver.

Changes in 1.4.2:

  bios misporgrammed them.
 other fixes for sis.c
 
Klaus Stehle <[e-mail]>:
 Fix gl_writen to behave as per the man page (not stop at nul char).

Ben Winslow <[e-mail]>:
 support for Wacom Graphire tablet/mouse.

[e-mail]:
 support for mouse type pnp (explanation of this type in gpm).

Krzysztof Nikiel <[e-mail]>:
 move mouse_init to vga_init (before giving up root privileges), and
  not closing mouse upon return to text mode. This enables svgalib
  programs to use the mouse device even when the device is only readable
  by root.

Matan Ziv-Av <[e-mail]>:
 Banshee fixes to support high resolution modes.
 nv3 fix to support nv3 (Riva128) cards again.
 nv3 fix to restore memory page number.
 fix gl_hline to do nothing if x1>x2 (rather than segfault) + man page. 
 workaround for double clock speed for some rage cards
 laguna (Cirrus logic 546X) driver.
 
Changes in 1.4.1:

Changes in 1.4.0:

Matan Ziv-Av <[e-mail]>
 vgapci uses /proc/bus/pci kernel interface, when available.
 Rage driver.
 Added static modes.
 Extended dynamic mode creation with vga_addtiming(3), vga_guesstiming(3),
  vga_addmode(3) and newmode config file option.
 Functions vga_cetcurrenttiming(3) and vga_changetiming(3), for mode
  tuning at runtime.
 All mmaps of /dev/mem are done by driver initialize function and
  vga_init, so /dev/mem file descriptor is closed when relinquishing root
  privileges. 
 Moved mach64.c driver to a different directory.
 vga_reset utility added to facilitate restoring textmode without
  rebooting, in case svgalib fails to do it properly.

Christian Groessler <[e-mail]>:
 Chips&tech driver fixes.
 Changing vga_setlinearaddressing to return error when in mode that does
  support linear.

 Rewrite of et6000 driver to comply with newer svgalib driver interface.

 Fixed bug in console switching when in background mode (it used to
  effectively disable console-switching after the first switch, which
  broke zgv).
 Made vga_getscansegment() and vga_drawscansegment() work correctly
  for non-4-pixel-aligned x locations in mode-X modes, and made
  mode-X vga_getscansegment() set page to *read*, not write.
