New Features of ZK 10.3.0
Summary
ZK 10.3.0 ships with a set of developer-focused improvements including a system-level Content Security Policy (CSP) switch, clearer patterns for multiple file downloads, expanded use of CSS variables for theming, and simplified OSGi packaging. The release also updates third-party libraries, fixes 50+ bugs, and provides guidance on dependency versions and Java 11 compatibility to help teams manage security and upgrades. The theming changes reduce long-term maintenance by letting developers set global CSS variables, and the Filedownload bundling recommendation ensures predictable multi-file download behavior across browsers. The project recommends upgrading to 10.3.0 (and using 10.3.0.1 for new downloads) to take advantage of these enhancements and stability fixes.
