The Sleep Scripting project has released version 2.1-b3. "A 'strict' mode that warns scripters for failure to declare a variable was added. An issue with scripts servicing multiple clients through listening sockets was fixed. Several functions were updated to accept an array or closure as an argument. When a closure is specified, the bridge will iterate over it until $null is returned. Scripter access to setting and querying the current debug level was added. Several other small bugfixes and enhancements were made."
