Since the switch to a semi-annual release cycle in 2017, Java 17 was the second version to be released with long-term support. Despite the shortened release cycles, there are several releases between the long-term supported versions that bring numerous innovations. This seminar covers the changes in Java versions 12 to 17. After the large-scale modularisation efforts introduced in Java 9, these newer releases focus on convenience language enhancements, performance improvements and preparations for future major changes. In addition, some legacy features have also been removed.
