0.38 Fri May 3 14:47:09 CEST 2002

• Removed a (silly) debug message.
• Fool-proof for ascii input.
• Numeric input works with LB::IP::input() (just as ascii input).
• Numeric input asks for input until it gets a valid input.

0.37 Wed Apr 24 08:54:00 CEST 2002

• New mechanism of libraries loading: loading instances of extension instead of a plain module.
• doc/library.pod modified to reflect this.

0.36 Mon Apr 22 20:44:10 CEST 2002

• jqbf98 now understands the -v flag (verbose)
• New examples tpr00.bf, palin.bf
• IP.pm now has two methods spush_vec and spop_vec. Befunge.pm modified to take advantage of those methods.
• IP.pm now has a method spush_args to push (and convert) arguments on the stack.
• IP.pm comes with a storage facility to allow library to fetch and store whatever data they want. This is highly experimental and the interface may change in future releases.

0.35 Tue Apr 16 17:20:29 CEST 2002

• LaheySpace::labels_lookup() now also returns the velocity that found the label.
• Minor pod update.

0.34 Tue Apr 16 15:00:27 CEST 2002

• Minor bug fix in LaheySpace.pm. I discovered it by chance, since it's a tiny little bug that did not seem to break anything.
• LaheySpace now has a labels_lookup() method, that allow to search for labels inside comments. This will be used in Inline::Befunge and maybe some extensions will use this non-standard mechanism.
• Minor update to doc/library.pod

0.33 Mon Apr 15 17:21:23 CEST 2002

• Fancy stuff added in order to support Inline::Befunge (does not change the default behavior)
