The latest release of Quipu is now available, and is distributed as part of
ISODE-6.0 (announced earlier on these lists).

Since the ISODE 5.0 release, there have been a large number of changes of 
changes to Quipu these are summarised below.

 - Enhanced security (both Authentication and Access Control)
	- DSP security holes protected against
	- Better use of cached ACL lists
	- Protected simple authentication can be used (see recent messages
		to this list)
 - Speeding up of large searches
	- Size of the in core database reduced.
	- Use of a "malloc" that knows about the DSAs requirements.
 - Extended attribute handling (all the X500 attributes are now supported)
	- Easier to add new attribute syntaxes.	
 - Improved scheduling.
 - DSP operations now fully asynchronous.
 - Support of "timelimit".
 - Use of "Quipu Application Context" for DSP links to other Quipu DSA's.
 - Algorthimic choice of which DSA to contact, as opposed to the random
	choice made in 5.0
 - Two new user interfaces: "fred" and "widget2".
 - Removed some security holes from "dishinit".
 - Aligned to the standard.
 - Increased Robustness.
 - Improved manual.
 
It is suggested anybody running a Quipu DSA updates their code to 
this version as soon as possible.

Any discussion of these features should probably take place on the "quipu"
list only.
