CDPD-124438: Apache Knox Gateway UIs load the gear and pin icons from the internet, breaking icons in air-gapped environments
7.3.3.0
Fixed an issue where, in air-gapped networks and in environments that block outbound internet access from Knox UI client browsers, Apache Knox Gateway UIs tried to load the gear and pin icons from the internet. The browser could not download the icons, so they appeared as literal ligature text instead of glyphs. Knox now bundles these icons as local inline SVGs so the UIs no longer request them from the internet, and icons render correctly when outbound internet access is blocked.

CDPD-124561: Apache Knox Gateway default login page flashes before modern-themed login page is displayed
7.3.3.0
Fixed an issue where the Apache Knox Gateway default login page flashed briefly before the modern-themed login page appeared. The modern-themed login page now displays correctly.

CDPD-97987: AWS SDK for Java v2 log messages are missing from Knox IDBroker logs
7.3.3.0
Fixed an issue where AWS SDK for Java v2 log messages were missing from Knox IDBroker logs when IDBroker performed AWS credential brokering. Knox no longer uses the AWS SDK bundle fat JAR, which included its own SLF4J implementation that overrode Knox logging configuration and suppressed log output from AWS SDK classes. Knox now uses individual AWS SDK modules, and AWS SDK log messages appear in IDBroker logs as expected.
