# RELEASE NOTES ## spatstat 1.42-1 ### 05 June 2015 We thank Andrew Hardegen, Tom Lawrence, Robin Milne, Suman Rakshit, and Brian Ripley for contributions. ### OVERVIEW * Urgent bug fix. * More robust simulation of cluster processes. * Slightly accelerated. * Version nickname: 'Vogon Poetry' ### NEW FUNCTIONS * boundingbox.solist Method for boundingbox for lists of spatial objects. ### SIGNIFICANT USER-VISIBLE CHANGES * rThomas, rMatClust, rCauchy, rVarGamma, rNeymanScott New faster algorithm which is more robust against extreme values of the parameters. * rNeymanScott New argument 'nonempty' controls choice of algorithm. * solist, as.solist Accelerated. * as.list.hyperframe Accelerated. ### BUG FIXES 1. residuals.mppm Brought some computers to a grinding halt, due to the bug in solist(). Fixed. 2. solist, as.solist In rare cases, the format was corrupted, or the algorithm never terminated. Fixed.
