This release includes all 4 major components:
the UIMA Java SDK, UIMACPP, UIMA-AS (Asynchronous Scalout capability),
and a growing set of UIMA Addons. It is backwards compatable with previous releases, except
that Java 5 is now the minimum Java level required.
The add-ons package contains many new components and annotators.
The UIMA-AS (Asynchronous Scaleout)
framework is extensively enhanced with much more support for error/failure recovery, driven by feedback
from actual use in several large scale deployments. The base framework now supports Java 5 generics, and
is enhanced to make it even more
light-weight and efficient; for example, it now supports a new network serialization format
for communicating with remote
annotators using a "delta-CAS" - limiting the response sent to just those items which have changed.
Please see the release notes on the downloads page, for a more complete summary
and a complete list of changes.
