This is the consolidated list of changes between Tapestry versions 5.3.2 and 5.3.3. Tapestry 5.3.3 is a drop-in replacement for prior Tapestry 5.3 releases. To upgrade, just update the Maven dependency in you POM file (or download the new JAR file) and the new version will just work. However, please review the How to Upgrade instructions before upgrading.
This is a very modest bug fix release, but it does straighten out a significant problem with Java component classes containing non-private fields.
For those developers not using Maven or Gradle, you'll be pleased to know that this release now includes the option of a binary download containing Tapestry's modules and main dependencies. More details are on the Download page.
