3.0.0

Version 3.0 of the layout dialect written in java is a complete Java module. The module name is synchronized from upstream because it is used as a replacement library.

Package renamed from nz.net.ultraq.thymeleaf to nz.net.ultraq.thymeleaf.layoutdialect.

Check the migration guide out on the original documentation site to help make the assessment of what an upgrade to 3.0 would entail for you.
