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 fixes the bug that prevents --checksum option from
working correctly. It also fixes the bug that log file is not created
if a warn level log is created before log file is opened. Now aria2
doesn't assume download has completed just because file size matched.
The old behavior is problematic because aria2 just assumes download is
completed but in reality it is not.
