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

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

This release adds the ability to save unfinished downloads as text
file.  aria2 can read the file with -i option on restart.  This
release also adds the ability to download file from 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. 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.pause, aria2.unpause,
aria2.shutdown, and their families.  The new exist status code '8' was
added. The bug that makes aria2 hang when system time changes while
aria2 is running was fixed on MinGW32, Mac OS X and the system which
has clock_gettime().  Several other bugs also have been fixed.

Changes
-------

 * Added warning for the system which lacks clock_gettime with
   CLOCK_MONOTONIC.

 * Fixed the bug that hash check hangs when aria2.pause is issued
   while aria2 is checking piece hashes.  Fixed the bug that the
   download is paused after file allocation completion even if
   aria2.pause is issued during file allocation.

 * Fixed compile error on opensolaris

 * Added aria2.forcePause, aria2.pauseAll, aria2.forcePauseAll and
   aria2.unpauseAll XML-RPC method.

 * Use clock_gettime(CLOCK_MONOTONIC, ...) if it is available and
   usable to prevent from aria2 from being affected by system time
   change.

 * Added aria2.pause and aria2.unpause XML-RPC method.  aria2.pause
   pauses the download denoted by gid. gid is of type string.  The
   status of paused download becomes "paused" and the download is
   placed on the first position of waiting queue. As long as the
   status is "paused", the download is not started. To change status
   to "waiting", use aria2.unpause method. This method returns GID of
   paused download.  aria2.unpause changes the status of the download
   denoted by gid from "paused" to "waiting". This makes the download
   eligible to restart. gid is of type string. This method returns GID
   of unpaused download.

 * Added --save-session=FILE option.  This option saves
   error/unfinished downloads to FILE on exit.  You can pass this
   output file to aria2c with -i option on restart. Please note that
   downloads added by aria2.addTorrent and aria2.addMetalink XML-RPC
   method are not saved.

 * Fixed the bug that FTP data connection is not established via proxy
   when --ftp-proxy is defined and --ftp-pasv=true and
   --proxy-method=tunnel.

 * 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.
