aria2 1.9.1
===========

Release Note
------------

This release adds the ability to download file scratch when aria2 sees
resume is not supported by remote server.  This feature is disabled by
default. See --always-resume option for details. --no-proxy option
accepts IPv4 network address with CIDR block.  --remove-control-file
option is added to remove control file before download begins.  aria2
now doesn't send "Accept-Encoding: deflate, gzip" by default.
--http-accept-gzip option was added to toggle this behavior.  aria2
now treats lines starting "#" in -i list as comments.  Several XML-RPC
methods were added: aria2.shutdown and aria2.forceShutdown.  The new
exist status code '8' was added.  Several bugs also have been fixed.

Changes
-------

 * Fixed the bug that web-seed URI is not percent-encoded.

 * Added aria2.shutdown and aria2.forceShutdown XML-RPC method.  These
   methods, as their name imply, shutdown aria2.  These methods are
   useful for Windows because it lacks signal mechanism.

 * Don't send "Accept-Encoding: default, gzip" by default. This is
   because some servers respond with "Content-Encoding: gzip" for a
   file which itself is gzipped file and aria2 inflates them. This is
   a problem if user doesn't want to inflate the file. Apparently this
   is server configuration error, but we cannot do anything about
   this. So we turned this off.  Added --http-accept-gzip option. If
   true is given to this option, aria2 sends "Accept-Encoding:
   deflate, gzip" request header and inflates response if remote
   server responds with "Content-Encoding: gzip" or "Content-Encoding:
   deflate".  We removed extension "tgz" hack in order not to inflate
   files with tgz extensions.

 * Made aria2 not send
   "application/metalink4+xml,application/metalink+xml" in Accept
   header for web-seeding URIs and tracker request.

 * Added --dht-message-timeout option.

 * Added --bt-tracker-connect-timeout and --bt-tracker-timeout
   option.

 * Documented that specifying --seed-time=0 disables seeding after
   download completed.

 * Drop connection if same Peer ID has been already seen.

 * Fixed the bug that waiting download unintentionally starts when
   URIs are added to it using aria2.changeUri XML-RPC method.

 * Fixed compile error with g++-4.4 on FreeBSD.

 * Fixed the bug that URIs added using aria2.changeUri XML-RPC method
   are not used immediately if there is no URI remaining before
   calling aria2.changeUri and the number of connection is less than
   the value in -s(or -C for Metalink downloads).

 * Added --always-resume and --max-resume-failure-tries option.  If
   --always-resume=false is given, when all given URIs do not
   support resume or aria2 encounters N URIs which does not support
   resume (N is the value specified using --max-resume-failure-tries
   option), aria2 downloads file from scratch.  The default behavior is
   --always-resume=true, which means if all URIs do not support
   resume, download fails. I think this is OK because user normally
   doesn't like to see that partially downloaded file is
   overwritten(this is particularly true if file size is big).  This
   option is useful when aria2 is used as a download backend and
   graceful falling back to overwritten behavior is preferable.  Added
   exit status value 8, which means download failed because server did
   not support resume.

 * Added --remove-control-file option.  This option removes control
   file(*.aria2 file) before download. Using with
   --allow-overwrite=true, download always starts from scratch. This
   will be useful for users behind proxy server which disables
   resume. For such proxy user, -C1 is also recommended for Metalink
   downloads to avoid establishing unnecessary connections.

 * Added v key in DHT message. aria2's DHT version is independent of
   the package version and we defined it as 1 at the moment. It is
   defined as DHT_VERSION in src/DHTConstants.h. aria2's DHT version
   scheme is "A2"+2bytes DHT version number in network byte order.

 * Fixed the bug that value of numSeeders in aria2.tellStatus XML-RPC
   method response is integer, while it should be string.  The man
   page says it is string.  When peer's port is not listening port,
   set '0' to port in aria2.getPeers response.

 * Lines starting "#" in -i list are treated as comments.

 * Accept IPv4 network address with CIDR block in --no-proxy option
   and no_proxy environment variable.  Current implementation does not
   resolve hostname in URI to compare network address. So it is only
   effecive if URI has numeric IP address.



aria2 1.9.0
===========

Release Note
------------

This release adds Metalink4 support and BitTorrent Local Peer
Discovery.  aria2.changeUri XML-RPC method was added. It enables you
to add/remove URIs to existing downloads dynamically.  The user and
password for proxy server now can be specified in command-line
separately.  We refactored the code based on profiler results, so
aria2 now runs more efficiently than ever. Russian and Simplified
Chinese translation were updated.

Changes
-------

 * Resurrected --http-proxy-user and --http-proxy-passwd option.
   Added --https-proxy-user, --https-proxy-passwd, --ftp-proxy-user,
   --ftp-proxy-passwd, --all-proxy-user, --all-proxy-passwd option.

 * Updated Russian and Simplified Chinese translation.

 * Added --reuse-uri option. This option has existed quite long, but
   been hidden.

 * Fixed the bug that filename is percent encoded where it must be
   percent decoded in sendMdtm().

 * Added getServers XML-RPC method. It returns currently connected
   HTTP(S)/FTP server and download speed, etc.

 * Added 'status' key to the response of getUri XML-RPC method.

 * Added changeUri XML-RPC method.  This method removes/adds URIs
   dynamically.

 * Replaced null or control characters in file path with '_'.  For
   MinGW32 build, additional characters which is not allowed in
   Windows kernel are also replaced. util::detectDirTraversal() now
   returns true if given string contains null or control characters.

 * Discard torrent file if path data in it contains directory
   traversal directives.  Discard metalink:file element in Metalink3
   format if its name attribute contains directory traversal
   directives.  Ignore name attribute of metalink:signature element in
   Metalink3 format if it contains directory traversal directives.

 * Added Metalink4 support. Files with same metaurl are
   grouped and downloaded in one RequestGroup.

 * Added --bt-lpd-interface option to specify the interface to use for
   Local Peer Discovery. LpdMessageDispatcher object now has its own
   socket. LpdMessageReceiver's socket is binded to multicast address
   to only receive multicast packets.

 * Added Local Peer Discovery. It is disabled by default. Use
   --bt-enable-lpd to enable the function.
