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 an option to limit the number of connections to the
same host in each download. aria2 now chooses server which is least
used in aria2c instance. This release also adds Chromium cookie
support and HTTP only conditional download support which is download
file only when the local file is older than remote file. aria2 now
can handle %2F in FTP URI properly. HTTP/1.1 chunked decoder was
fixed. For Linux, aria2 uses fallocate by default if it is usable.
