We uploaded a second (and likely final) release candidate for 3.3.5. We are switching to github for the releases (and moving away from Sourceforge). Since github simply extracts the release from the git repository, the release files do not contain pre-built documentation though.
Here are the main links:
C++ Wt: download wt-3.3.5-rc2.tar.gz and read its release notes
Java JWt: download jwt-3.3.5-rc2.zip and read its release notes
