Last week I converted a large project to UIMA 3.0.0. I updated the Maven dependencies, rebuilt all the JCas files and removed the old *_Type.java files. Everything compiled without problem. Got runtime errors that were fixed by finding a version of Xerces (version 2.4.0 in this case) that would keep all dependencies happy. For short runs with a single pipeline, I'm noticing about a 15-20% reduction in processing time and less memory usage (I presume due to GC on the CAS). I had already been running JDK 1.8 for some time. Am I correct in thinking that there is not a version of UIMA-AS that will work with UIMA 3.0.0? When might a UIMA-AS 3.0.0 be expected. Thanks / Dan

This is the first release of a major re-implementation of the UIMA Java SDK, aligning it with Java 8 and high performance multi-core processors. Apache UIMA <http://uima.apache.org> is a component architecture and framework for the analysis of unstructured content like text, video and audio data. This release is a major rewrite of the internals of core UIMA, and includes many new features, including: -- support for arbitrary Java objects in the CAS -- New semi-built-in UIMA types: FSArrayList, FSHashSet, IntegerArrayList, Int2FS map -- New "select" framework integrated with Java 8 Streams -- Elimination of concurrent modification exception while iterating over UIMA indexes -- Automatic Garbage Collection of unreferenced Feature Structures -- All around better integration into Java 8 idioms and generic typing See the UIMA News <https://uima.apache.org/news.html#05 Mar 2018>item ( https://uima.apache.org/news.html#05 Mar 2018 ) for more details. A full description of the new and changed parts is here: http://uima.apache.org/d/uimaj-3.0.0/version_3_users_guide.html This release requires Java 8, and is intended to be backwards compatible with existing Version 2 pipeline code, except for the need to regenerate or migrate (tooling provided) user-defined JCas class definitions. Please send feedback via the Apache UIMA project mailing lists. -Marshall Schor, for the Apache UIMA development team
