Release Notes: This release adds the ability to handle metalink files that contain relative URIs in the metalink:url and metalink:metaurl elements. The username and password specified on the command-line are now masked with "*" immediately after they are parsed, so that a ps listing cannot show username and password. In XML-RPC, aria2 now treats data without a data type tag as a string. In the MinGW32 build, cmd.exe is specified explicitly to run .bat files.


Release Notes: This release adds Mac OS X native SSL/TLS library support. The IPv6 asynchronous DNS is enabled by default, and A/AAAA lookups are done in parallel. The simple Happy Eyeballs algorithm has been implemented to mitigate long timeouts when connecting to IPv6 hosts on dual-stack hosts. The --save-session option only saves the options specified by the commandline or RPC.


Release Notes: This release fixes the bug which caused an invalid range error to be thrown when requesting range starts from 0 in HTTP downloads.


Release Notes: This release fixes the bug where active downloads were not saved with --save-session-interval and the bug where aria2 hangs when the size of the download result exceeds its maximum. BitTorrent UDP tracker support was added. If the filename specified using --save-session ends with ".gz", aria2 stores the session file in gzipped form. The -i option can handle this gzipped file as well as plain text files. A 1.15.2 based Portuguese translated manual was added.


Release Notes: This release fixes a bug that caused random crashes. It also fixes socket option setting failure on Windows.


Release Notes: This release fixes the bug which caused long-running BitTorrent downloads to stall. Several new options have been added.
