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 IPv6 support for FTP, BitTorrent and BitTorrent DHT.
For FTP, EPSV and EPRT command support was added. Enabling IPv6 DHT
requires several options, so please check out the usage example in man
page or wiki usage example page. By default, the asynchronous DNS
resolver does not handle IPv6 address. To work with IPv6 address, use
--enable-async-dns6 option. aria2 now listens on both IPv4 and IPv6
socket for BitTorrent, its DHT and XML-RPC. aria2 uses same port for
both IPv4 and IPv6. The ability to add/remove BitTorrent tracker
announce URI was added. The link error for
FallocFileAllocationIterator was fixed.
Please note that since 1.10.0 release, aria2 uses 1 connection per
host by default and has 20MiB segment size restriction. So whatever
value you specify using -s option, it uses 1 connection per host. To
make it behave like 1.9.x, use --max-connection-per-server=4
--min-split-size=1M. If you specify multiple hosts, aria2 will use
all of them and open multiple connections.
