aria2 1.15.0 released

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 JSON-RPC over WebSocket. It uses the same
request/response JSON objects with existing JSON-RPC over HTTP and
adds event notifications from server to client. See manpage for
details. TLS hostname check is rewritten based on RFC 6125 and it is
used for both GNUTLS and OpenSSL builds. The
--bt-remove-unselected-file option was added. This option removes the
unselected files when BitTorrent download is completed.
