Sun, 13 Mar 2011 16:01:00 +0100 wenzelm Path.print is the official way to show file-system paths to users -- note that Path.implode often indicates violation of the abstract datatype;

Wed, 05 May 2010 18:25:34 +0200 haftmann farewell to old-style mem infixes -- type inference in situations with mem_int and mem_string should provide enough information to resolve the type of (op =)
Sat, 06 Feb 2010 15:51:22 +0100 wenzelm proper treatment of paths passed to the shell -- to allow spaces in file names as usual;
Sat, 06 Feb 2010 14:50:55 +0100 wenzelm renamed system/system_out to bash/bash_output -- to emphasized that this is really GNU bash, not some undefined POSIX sh;

Tue, 27 Oct 2009 16:03:06 +0100 wenzelm more thread-safe access to global refs;
Wed, 21 Oct 2009 12:12:21 +0200 haftmann merged
Wed, 21 Oct 2009 12:09:37 +0200 haftmann curried inter as canonical list operation (beware of argument order)
Wed, 21 Oct 2009 12:02:56 +0200 haftmann curried union as canonical list operation
Wed, 21 Oct 2009 08:16:25 +0200 haftmann merged

Tue, 24 Feb 2009 16:12:27 +0100 blanchet Eliminated ZCHAFF_VERSION configuration variable, since zChaff's output format is identical in all versions since March 2003 (at least), and also because it forces users who want to use the latest versions to lie about the version number.
Tue, 10 Feb 2009 18:57:02 +0100 blanchet Added serial_string to SAT solver input and output files, to prevent multithreading chaos.
