 The user-visible changes between release 0.3.7 and 0.3.8 include:  
16    
17      o)  The IQ80321 (Xscale) machine mode is now working well enough to  Changes between release 0.4.1 and 0.4.2 include, among other things:
         run NetBSD/evbarm 2.1.  
18    
19      o)  Faster framebuffer output in some situations.      o)  The NetWinder emulation mode now works well enough to let
20            NetBSD/netwinder run from a disk image.
21    
22  Source code related changes include:          (NetBSD/netwinder has to be installed manually, though, because
23            there is no installation ramdisk kernel. The GXemul documentation
24            has an example of how to install NetBSD/netwinder using an emulated
25            NetBSD/pmax machine.)
26    
27      o)  I've finally begun to reimplement the MIPS emulation mode using the      o)  Algorithmics P5064 emulation works well enough to let NetBSD/algor

29          anything, but things are moving in the right direction.          be installed manually, using another emulated machine.)
30    
31      o)  Some changes to the concepts of input-only, output-only, and      o)  PCI configuration register writes can now be handled, which allows
32          input-output consoles.          NetBSD/Malta (evbmips) 3.0.1 and NetBSD/cobalt 3.0.1 to run from
33            PCI IDE harddisk images. (Previously, only NetBSD 2.1 worked for
34            the Malta and Cobalt emulation modes.)
35    
36      o)  Some more clean-up of PCI bus concepts.      o)  Some performance increases:
37    
38      o)  Machine definitions have been moved out of src/machines.c, and into          The virtual translation table update routine has been simplified

40            apparently results in a speedup for all 64-bit modes.
41    
42            For 32-bit MIPS, some more instruction combinations have been added.
