Since 2018, we get a new version of Java every 6 months.
Some are long-term supported versions that can be used for many years, while others are only maintained for a short time. Version 20 is such a short-term supported version.
So, what new features does this version bring? And why should we use it? And what can we expect from the next version, 21, in September that will be a long-term supported version?
Let's find out and learn more about the process of the OpenJDK evolution!
Note: if you want to read more about the changes in OpenJDK 20 with code examples and a lot of additional info, check out the post by Hanno Embregts, here on Foojay.
