Teiid 8.4 Beta2 for EAP 6.1.Alpha 发布了，可通过这里 下载 . 与 8.3 Final 版本比较，该版本包含如下新特性：
TEIID-2444 EAP Platform - the deployment platform for Teiid has been changed to EAP 6.1.Alpha1
TEIID-2429 Improved sort performance - improved sorts for large data sets especially under heavy load.
TEIID-2449 VDB Zips - added the ability to deploy non-Designer based vdb zip artifacts with the ability to place DDL outside of the VDB.xml via the DDL-FILE metadata repository.
TEIID-2423 TEIID-2470 Additional Embedded deployments - xml and zip vdb deployment options are available for Teiid Embedded.
TEIID-1092 Session Variables - added the teiid_session_set and teiid_session_get methods to maintain session variables.
TEIID-2326 Shared Mat Views - materialized views from imported vdbs will be reused rather than recreated in each importing vdb.
TEIID-2344 Automatic DB Version Detection - the JDBC translator database version property in most circumstances will not need to be set manually (non-available JDBC sources in partial results mode or source with connection factories that require an ExecutionContext to obtain a connection will require manual setting of the database version metadata property. The affected sources are: db2, derby, oracle, postgresql, sqlserver, sybase, teiid)
TEIID-2453 STRING_AGG - added the string_agg aggregate function for concatenating binary and character strings.
同时解决了大约 60 issues ，大约 2 周后将发布 CR 版本。
