v0.22

Added

• Add multi-value support for Assert<String>.contains() and doesNotContain()
• Add isEqualByComparingTo to compare objects by compareTo instead of equals this is useful for cases like
  BigDecimal where equals would fail because of differing precision.
• Add containsOnly for arrays.

Changed

• Minimum supported kotlin version is 1.3.70
• Updated opentest4j to 1.2.0. This changes the multiple assertion message to include each exception class name.
• Moved containsAll, containsNone, and containsOnly from Collection to Iterable to make
  them a bit more flexible.
• containsAll, containsNone, and containsOnly error messages now include the expected and actual lists.
• Unwrap exceptions thrown by prop(callable: KCallable<*>) to make them more clear.
• Add all exception stacktraces to a MultipleFailuresError with Throwable.addSurpressed on the jvm (used when
  collecting multiple exceptions with assertAll). Unfortunately, if you are using gradle you won't see this due to a
  known gradle issue.
• No longer wrap exceptions in AssertionErrors when using given and transform. Warning: this is techinicaly a
  breaking change as code like:

  try {
      assertThat(foo).given { throw MyException("error") }
  } catch (e: AssertionError) {
      // assume caught
  }

  will no longer be caught. But you shouldn't be writing code like that anyway ;)

Fixed

• Don't let assertAll capture OutOfMemory errors.

Breaking Changes

• Previously deprecated methods (as of 0.18) are now errors.
