RELEASE NOTES 

		spatstat 1.8-1

	 	24 November 2005


OVERVIEW

	Version 1.8 of spatstat will include 

		- support for different types of data

		- improvements to standard techniques

		- performance improvements.

	In preparation for this, release 1.8-1 has changed some of
	the basic infrastructure. It also contains a few bug fixes.
	 
IMPROVEMENTS/ENHANCEMENTS

	The functions as.ppp() and as.owin() are now generic functions. 
	This does not affect anything inside spatstat. 
	However it makes it easier for other packages 
	to create 'ppp' objects and 'owin' objects.

BUGS

	[1] pcf.fv sometimes caused a divide-by-zero error.
	This has been fixed.

	[2] pcf.ppp crashed if the 'translation' edge correction
	was not selected. This has been fixed.

	[3] owin did not correctly deal with poly=NULL and mask=NULL.
	Fixed.
