We've just published the first release candidate for RAP 2.2. This build
includes a number of important fixes and improvements. Most notable, the
new Row Templates have been improved and the web client has been
adjusted to detect the new IE11 properly.
If you deploy RAP applications as a WAR file, it may be interesting that
one long-standing problem could be resolved that prevented the servlet
container from shutting down cleanly .
The New and Noteworthy  has a detailed list of changes and fixes.
Thanks to all who helped us testing. You reports on this list and in
bugzilla are most valuable!
