- Make it final and immutable.
- Use pattern-based parsing, which allows to also parse the ReleaseStatus and the statusVersion.
- Implement toString() method.
- Implement equals() and hashCode(), which is a strong recommendation when implementing Comparable: From the JavaDoc: "It is strongly recommended that (x.compareTo(y)==0) == (x.equals(y))", which was not the case.
- Allow CharSequence
- Simplify getVersionString() method (less duplicate code).
- Improve compareTo() method by properly comparing more than 2 digits and also comparing ReleaseStatus and statusVersion
