Release Notes: Relatively major changes have been made to the library. The build system (i.e. Makefiles) was reworked, and the package now (hopefully) builds natively under Windows. This release is also notable as the first one made using git instead of CVS.
Release Notes: Some minor changes to the code and a major change in the attribution style.
Release Notes: Some nasty bugs were fixed. For example, NILL now has a working TRACE feature again, ILS and ILL translate single chars to chars instead of strings of one char, and all the samples under the samples/ directory now compile. The Refal part was reworked, so the release contains the new version. Some minor renamings were done. For example, the ugly word "changeable" was replaced with the correct word "mutable". This can potentially affect the existing code, but the probability of this is very low.
Release Notes: The version includes a reworked implementation of the Refal computation model. This implementation seems to be notably faster than the previously existing one.
Release Notes: Only minor internal changes were made, related to the SExpressionSpecialToken and its usage. Ignore this release if you don't know what all this is about (assuming you've got version 0.6.17, because all the past releases contain really nasty bugs).
