News in Release 3.2

• Atom garbage collection, whereby memory for atoms no longer referenced by the Prolog execution can be reclaimed. With the introduction of this feature, the maximum length of atoms has also been increased from 1024 bytes to 65532 bytes. library(strings) has been modified to support the long atoms, only allocating space for long atoms as needed.
• The TCP library has been significantly enhanced to provide more efficient passing of terms between Prolog processes, more functionality for server processes and support for input callbacks, where predicates can be called either when a specified file descriptor becomes ready or at a specified time.
• A new licensing system has been introduced with this release. A license manager program is provided to setup the licenses and provide information on licenses installed.
• The cross-referencer tool has been replaced by a new version that is tuned to finding unreachable code in large programs.
• Windows note: Windowed executables can be built using the -W option to qld. Such executables direct the standard I/O streams to a dedicated window.
• Windows note: Some minor changes in the directory structure have been done, e.g. the host_type and system directory name has changed from i386 to ix86.
