aria2 is a lightweight multi-protocol & multi-source, cross
platform download utility operated in command-line. It supports
HTTP/HTTPS, FTP, BitTorrent and Metalink.
This release adds the ability to handle metalink file which contains
relative URI in metalink:url and metalink:metaurl element. The
username and password specified in command-line are now masked with
"*" immediately after parsed, so that ps cannot show username and
password. In XML-RPC, aria2 now treats data without data type tag as
string. In MinGW32 build, cmd.exe is specified explicitly to run .bat
file.
