Logtalk is an object-oriented logic programming language that can use most Prolog implementations as a back-end compiler. As a multi-paradigm language, it includes support for both prototypes and classes, protocols (interfaces), component-based programming through category-based composition, event-driven programming, and high-level multi-threading programming.

This release changes the semantics of complementing categories, allowing its use to patch existing object code, fixes two bugs in the processing of meta-calls, allows open lists of terminals in the body of DCG rules, adds two new examples, and improves support for the Vim text editor and for Exuberant ctags.
This release extends the uses/2 directive semantics, adds a scope/1 predicate property, features compiler and runtime improvements which simplify building applications when Logtalk libraries are pre-compiled and pre-loaded, adds new list library predicates, and includes portability updates for Lean Prolog and SWI-Prolog.
This is a minor release with some bugfixes and minor compiler and runtime improvements.
