The edition also introduces "weary," a library for creating RESTful services, "sykobot," an IRC bot with diverse functionalities for the #archlinux channel, and "CssMerger," a C# application that streamlines CSS file management for ASP.NET users by merging separate files into a single cohesive unit.
