Performance is Everything

This came shortly after 1.4.0 because 1.4.0 introduce severe performance problems for some users.

New and Enhanced Features

• Added constraint annotation @NotBlank for String parameters

• Generated email addresses get a few more edge cases

Breaking Changes

• Removed Arbitrary.unique() which had been deprecated in 1.4.0

• Removed annotation @Unique which had been deprecated in 1.4.0

• Removed Arbitraries.constant(..) which had been deprecated in 1.3.2

Bug Fixes

• Fixed degraded generation performance
  introduced in version 1.4.0.

• Arbitrary.withoutEdgeCases() did not really get rid of all edge case generation.
  Now it does.

• Some arbitrary types, e.g. Arbitraries.lazyOf() could not be used in sampling.
  Now all should work.

• Bounded shrinking could previously result in an OutsideJqwikException.
