Description

This is a release with a major performance bug fix for the dynamical sampler

A major performance regression has been discovered that lead to dynamic nested sampling batches becoming slower and slower. The regression was introduced in 1.2 and can easily lead to a factor of several slower performance if a large number of batches is used. ( see #415 ) Some small fixes related to resuming of interrupted sampling were applied as well.
