CWSDPMI r4 has been released and is now available on SIMTEL in the v2misc 
directory.

CWSDPMI r4 fixes some bugs, increases some limits, and includes a clearer
and more lenient license agreement.  Unless you have one of the problems
below with r3, you probably don't need to upgrade.

CWSDPMI r4 features:
 Map HMA for non-VCPI clients
 Fix 0x800 mapping for 0x1nnnnnnn addresses
 Check 0x800 mapping for invalid addresses
 Use XMS extensions to support >64Mb XMS memory
 New license agreement (GPL or binary w/o notification)
 Dynamic allocation for physical and swapfile usage bitmaps.
    A new cwsparam field for max swap usage.  The user can decide how
    much virtual memory to allow in exchange for 32 bytes of real memory
    per Mb swap.  The base footprint drops by 8Kb and runtime footprint
    increases between 0 and 16Kb, depending on the amount of swap you want
    and how much disk you have free.  Now limited to 256Mb virtual and
    256Mb physical for a total of 512Mb memory.
 Flag to disable pagetable allocation in UMBs (activated in cwsparam)
 Flag to pre-allocate memory at DPMI entry (activated in cwsparam)
