There seems to be a little problem with the JDK link, here is the link to download page.
The documentation page is here.
From the above mentioned documentation this seems to be the new features of the release:
The short version
- SSO between OBIEE (clasic home page) and VA / DV (new home page).
- Publisher new features.
The longer version
New Security Features in Oracle BI EE 12c (12.2.1.3.0) include:
• This release uses OpenSSL
version 1.0.2h.
• Lightweight Single Sign-On
(SSO)
Lightweight Single Sign-On (SSO)
Users can log in to Oracle Business Intelligence once and navigate
between the Classic (Analytics) Home page, Visual Analyzer, and the new Home
page.
Lightweight SSO is enabled by default in Oracle Business
Intelligence for new installations only. If you patched Oracle BI EE to the latest
release, lightweight SSO is not enabled by default.
If external SSO is configured, lightweight SSO defers to the
external SSO configuration. Oracle BI EE uses the same mechanism to enable
internal lightweight SSO and external SSO.
If you need to disable lightweight SSO, use the WSLT disable SSO
command.
