The source archive for asm 0.2.1 was uploaded moments ago [1], with the following changes:

• the maximum number of operands per instruction was raised to five (and is easier to tweak)
• architecture plug-ins can now be (de)initialized
• deassembly can now apply to the whole file, or code parts only
• fixes for the deassembly of strings on the command-line
• more accurate deassembly of the x86, amd64, sparc and sparc64 architectures, as well as ELF and PE file formats
• otherwise nicer output (address size...)

Of course more information can also be found in the project's homepage [2].
