4.4.0 breaks Java 8 support

.m2/repository/com/github/jknack/handlebars/4.4.0/handlebars-4.4.0.jar(com/github/jknack/handlebars/Context.class) [ERROR] class file has wrong version 61.0, should be 52.0

It seems the Java baseline was changed here: https://github.com/jknack/handlebars.java/commit/70d9261cf133969d373614d89e3e05cebb6f289c. As a user of handlebars and a maintainer of a project (micrometer-docs-generator) that uses it, I find quite unfortunate that the Java baseline was changed in a minor version and that the release notes does not mention this rather important detail.

It breaks a lot. "Upgrade to Spring 6" means javax -> jakarta! That should have been a major version bump!

I think it is still possible to fix this by re-releasing

• 4.3.1 as 4.5.0
• 4.4.0 as 5.0.0

@jknack what do you think?

The above suggestion is a really good idea. It's relatively simple to execute, and would clean up a lot of dependabot failures.

And, many thanks for providing us with a great Handlebars library. It is much appreciated!
