Versioning
ZK products follow semantic versioning, where the three digits refer to MAJOR.MINOR.PATCH respectively. In the case where a hotfix is required, a fourth digit is introduced. Except for major (first digit) upgrades, compatibility is generally maintained, or a fall-back mechanism is available.
Upgrade References
An introductory smalltalk is published for every MAJOR and MINOR release. For example New Features of ZK 9.5. The smalltalk highlights the most important changes as well as provides upgrade tips for upgrading to that specific version. View all New Features articles.
A detailed release note containing a list of fixed issues is available for every new release, including hotfixes. For example, ZK 9.0.0 release notes. The full release history can be found here.
An “upgrade notes” section will be included at the end of a release note when needed. The “upgrade notes” section points out API changes or changes that developers will most likely need to take actions accordingly.
You can follow the same naming conventions as the examples provided above to search for the upgrade references you are looking for.
Important/breaking changes

Upgrade Process
Upgrading from ZK 5 (or later) to the latest version should be manageable. The steps are:
Specify the version you wish to upgrade to in your maven POM file, or, download corresponding binary files manually and put them into your project. It is important to make sure all ZK jar files are in the same version.
Then, fix any compilation errors and configure the required fallback settings by referencing the Upgrade References.
Checklist
To estimate the upgrading effort, we suggest a checklist:
- Check Custom Components
- check if there is any ZK_Component_Development_Essentials/Creating_the_Configuration_Files/The_language-addon that might declare custom components. Since you might need to review it after the upgrade.
- Check configuration description (zk.xml)
- Check each property in zk.xml upon ZK Configuration Reference to see if there is any change in the new version.
- Check Custom Appearance (CSS)
- If you customize a component's appearance with CSS, you might need to review it for the new version.
- Check Programs Using ZK JavaScript API
- If you customize a component with JavaScript, you might need to review it for the new version.
- Check Bug Patches
- Check Bug Tracker or release note for the existing bug patch. If that bug is fixed in the new version, you can remove the patch.
- Check for Java Compiler Error
