@vedran_pavic Java 11 was an option. But with JDK 11 LTS free updates ending before JDK8’s , most of the upgrade pain being there, and all the missing cool language features introduced as of 12…
At that point staying on JK8 looked almost more appealing!
@vedran_pavic Spring pays attention to backwards compatibility with its API, flexibility with 3rd party dependencies - but Spring also has a responsibility to use a sane baseline for the entire community and move the ecosystem forward.
@vedran_pavic So far the response from the community has been quite positive. The recording of Juergen’s talk at #SpringOne will be live soon. Hopefully we’ll get more feedback!

Current Framework 5.3.x generation has a Java 8 + Java EE7 baseline but tracks recent APIs and Java versions. This is the LTS generation Spring Boot 2.6 and 2.7 will be based on.
First 6.0 milestone by the end of 2021.
Spring Framework 6.0: Java 17 + Jakarta EE 9 baseline.
The Spring team recommends an upgrade to Java 17 LTS, getting all the performance and language benefits.
The 6.x line will follow further with Java & Jakarta evolution.
