Thymeleaf 1.0.0-beta4 has just been published.
This is a minor update from 1.0.0-beta3, basically adding some new i18n-related features for obtaining externalized messages from tag/attribute processors.
As a companion for this release, a new article titled "Say Hello! Extending Thymeleaf in 5 minutes" has also been published [
http://www.thymeleaf.org/sayhelloextendingthymeleaf5minutes.html ], and another article explaining more advanced extension concepts will follow in the next days.
Regards,
Daniel.
