The previous release 0.1.3 was the first approach to introduce a wait pattern to Hamcrest Matchers.
Release 1.0.0 incorporates the feedback that Hamcrest API should meet functional requirements and thus a new class Probe got introduced. It feels much more straightforward especially when using together with matchers available from Hamcrest Library.
In addition to this this release contains some additional matchers around reflections - especially dedicated to utility classes. So for example it tests (and code coverages) the recommended private constructor for utility classes or validates that the utility class is declared final.
