The 3.4.2 release introduces a simple API for building attribute maps and
fixes an occasional ArrayIndexOutOfBoundsException
Attribute map builders
As of version 3.4.2, Carrot2 API makes it possible to build attribute maps
in a type-safe fashion. Please see the
Fix for an occasional ArrayIndexOutOfBoundsException|
When versions 3.4.1, 3.4.0 or 3.3.0 of Carrot2 algorithms are used within a
pooling controller (ControllerFactory#createPooling()), an
ArrayIndexOutOfBoundsException may occasionally be thrown during
initialization or processing. All Carrot2 APIs and tools in version
3.4.1, 3.4.0 and 3.3.0 are affected by this issue. Version 3.4.2 is
free from the defect.
For a complete list of improvements and bug fixes, see JIRA
issues fixed in version 3.4.2. For more new features, please see release 3.4.0 and release 3.3.0 notes.
