JDeveloper 10.1.3.1 (Build 3984) is now in production and can be downloaded from OTN.
The Feature Matrix can be found [Here].
The list of bugs fixed in this release [Here].

Note that JDeveloper 10.1.3.1 does not automatically migrate the ...ViewController/public_html/WEB-INF/lib directory to use the latest adf-faces-impl.jar or(*)  jsf-impl.jar
You should manually copy the files <JDeveloper_Home>/jlib/adf-faces-impl.jar and  <JDeveloper_Home>/jsf-ri/jsf-impl.jar to your project directory .../WEB-INF/lib

The right version of adf-faces-impl.jar has the following in its Manifest.mf:

(...)
Built-By: sobryan
(...)
Build-Jdk: 1.4.2_09
(...)

NB: adf-faces-impl.jar from both versions have the same size of 3,918,976 bytes. So you cannot distinguish them on this criterium.

The right version of jsf-impl.jar has a size of 796,261 bytes.
Its Manifest.mf file includes the following information:

(...)
Implementation-Version: 1.1_02-b08
(...)

If you don't copy the right files, you may encounter the following symptoms:

1. Bugs that should be fixed in this release still reproduce
   This happens after the migration from JDeveloper 10.1.3.0 Build 3673
   
   
2. Running your application stops with a runtime exception after migration from JDeveloper 10.1.3.1 Developer's Preview (Build 3914):
   

   java.lang.NoSuchMethodError:

(*) Depending on your migration path, from JDeveloper 10.1.3.0 (Build 3673) directly, or through JDeveloper 10.1.3.1 Developer's Preview (Build 3914), one or the other file may be migrated correctly.
