Hi guys, Martin's GWT upgrade patch [1] just landed into ovirt-engine master. [1] http://gerrit.ovirt.org/#/c/32135/ Current oVirt UI tech stack is GWT 2.6.1 + GWT-Platform 1.3.1 + GIN 2.1.2 Since GWT 2.6 supports Java 7, source compliance for both frontend and backend code is now unified as Java 7. We should consider removing stuff like this: org.ovirt.engine.core.common.utils.ObjectUtils#objectsEqual in favor of using proper Java 7 APIs like: java.util.Objects#equals GWT 2.6 adds support for IE 10 ('ie10' user agent), too. This hopefully means less potential issues with IE 10 and above, since in our GWT host page, we're telling IE to behave as IE 10 if possible: <meta http-equiv="X-UA-Compatible" content="IE=10"> We ran Selenium tests on WebAdmin & UserPortal applications for Firefox and IE 8-10 to ensure there are no obvious regressions. If you find any issues or weird behavior, please contact me, Alex or Martin. Thanks, Vojtech
