Vaadin Framework 8.20.0

Changes in this version:

• Moved vaadin-portlet package contents from com.vaadin.server to com.vaadin.portlet namespace. This is a BREAKING CHANGE and will require you to update your imports. This is a necessary change in order to be able to support OSGi deployments (specifically under the latest Liferay 7 releases.

  • PLEASE NOTE THAT THIS IS A BREAKING CHANGE! - you need to update references to classes provided by vaadin-portlet from the com.vaadin.server to the com.vaadin.portlet namespace. The complete list of classes is as follows:

    • com.vaadin.portlet.LegacyVaadinPortlet
    • com.vaadin.portlet.RestrictedRenderResponse
    • com.vaadin.portlet.VaadinPortlet
    • com.vaadin.portlet.VaadinPortletRequest
    • com.vaadin.portlet.VAadinPortletService
    • com.vaadin.portlet.VaadinPortletSession
    • com.vaadin.portlet.WrappedPortletSession

    and

    • com.vaadin.portlet.communication.PortletBootstrapHandler
    • com.vaadin.portlet.communication.PortletDummyRequestHandler
    • com.vaadin.portlet.communication.PortletListenerNotifier
    • com.vaadin.portlet.communication.PortletStateAwareRequestHandler
    • com.vaadin.portlet.communication.PortletUIInitHandler

    If you've referenced any of these classes, they will have been in the com.vaadin.server and com.vaadin.server.communication packages, respectively.

• Improved OSGi packaging for vaadin-portlet. See issue #12575.
• Fixed an issue where push connections could get stuck when using @PreserveOnRefresh as requests intended for a new push connection would instead be queued on an old one. Now old connections are closed immediately on reconnect. See issue #12577.
• Fixed Push connection operations synchronization so that a connection won't be disconnected while there are messages pending. This would result in NullPointerExceptions being thrown. Makes the isConnected() call correctly reflect current state. This is a backported fix from Flow. See Flow issue #15571.
• Fixed an issue where undelivered push messages would get lost, resulting in a need for UI resynchronization. Push messages are now kept in cache until a client acknowledges receipt. This is a backported fix from Flow. See Flow issue #15205.
• Improved performance in UIs with assertions enabled. Some assertions would check for the presence of MPR on every run. MPR is now only detected once and the check result is cached. See issue #12572.

Vaadin Framework 8.19.0

• Changed license from Commercial Vaadin Developer License 4.0 to Vaadin Commercial License version 1. This change does not affect active subscribers, but it does mean that future releases of Vaadin Framework may move from dev- and build-time license checking to runtime license checking. Version 8.19.0 does not do that yet.
  See LICENSE file in the downloadable package or the Vaadin Commercial License and service terms document for more information.
• Fixed issue #12562. The internal state of ComboBox got confused when adding new items after calling clear().
• Improved the vaadin-server-mpr-jakarta and vaadin-compatibility-server-mpr-jakarta POM dependency definitions such that these packages do not pull in vaadin-server and vaadin-compatibility-server as unwanted dependencies, respectively.
• Fixed a number of assertion functions which would fail when MPR was in use. Improves testability of the framework and should allow running with assertions enabled in MPR configurations.
• Removed logging of Atmosphere version while MPR is in use. This fixes runtime failures under some configurations.
• Updated Atmosphere to version 2.4.30-vaadin5 in order to make Vaadin Framework 8 compatible with Jetty 10.
• Updated Vaadin License Checker to version 1.11.2 to support new license model.
