vcov.ppm

That is, entries of the Fisher information matrix were underestimated,
because some contributions due to interaction were omitted
(due to a coding error).
Fixed.
density.ppp
Crashed when se=TRUE if there were multiple columns of ‘weights’.
Fixed.
rbind.hyperframe
Crashed unless all arguments had the same number of rows.
(Spotted by Maximilian Vogtland).
