    Release Notes: This is a bugfix release. The version number jumped from 0.4.1 to 0.9.0 to reflect that cfunge is now reaching a stable version. A bug has been fixed where leading spaces would be lost when loading a file if the file used CR (Mac) line endings. Buggy handling of negative arguments to the j instruction (jump) when the jump target was on the edge of the program source has been fixed. There is a small bugfix in the tool used to automatically generate the fingerprint listing for the man page; it erroneously escaped hyphens.

      Release Notes: Major highlights in this release include tracking of exact bounds for Funge Space (an option at compile time) and support for disabling some heavy parts of cfunge to reduce memory usage. Many bugs have been fixed.

        Release Notes: This release adds support for some more fingerprints (DATE and NCRS), speed up execution quite a bit, and fixes several bugs. Cfunge now needs cmake 2.6 to build (previously cmake 2.4 also worked).

        •  30 Oct 2008 17:28

          Release Notes: Many common Befunge programs will run a lot faster due to optimized Funge-Space (using a static array for the most commonly used areas, and only using a hash table outside that). fflush() is called less often now. Several bugs have been fixed (including a rare crash bug). All I/O is now done using unsigned chars, instead of "whatever is native to the system", leading to more predictable behavior and better standards conformance.

            Release Notes: Since the last release, a bug in K in SOCK has been fixed, FING has been updated to new specs, and checks for certain long double instructions have been added, with fall backs on double functions. There have also been a number of smaller bugfixes.
