aria2 1.18.9 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 releases fixes memory leak with OpenSSL and crash on OSX when
proxy is used. We added several new features. Adler32 checksum is
now available in --checksum option and hash element in Metalink files.
We added --bt-detach-seed-only option, which excludes seed-only
downloads when counting concurrent active downloads (-j option). We
disabled SSLv3 by default. If you ever want to enable it or further
tune the TLS protocols to enable, use new --min-tls-version option.
--bt-force-encryption option was added to make requiring BitTorrent
full encryption easier. From this release, we build Android binary
using API level 16.
