After three years of development, on April 24th, a new version of ECL, the Common Lisp interpreter, was released. ECL, published under the LGPL-2.1+ license, can be used both as an embedded interpreter and for building stand-alone libraries and executable files (there is a possibility of translation to C).
Changes:
- support for local nicknames in packages;
- support for atomic operations;
- specialized representation of floating-point complex types;
- port on iOS;
- fixes for weak hash tables and weak pointers;
- fixes for race conditions in ECL internals;
- synchronization and custom tests for hash tables;
- improved metastability and improved Meta Object Protocol (MOP) support.
The project also has a second maintainer.
