aria2 1.10.1
============

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

This release adds IPv6 support for FTP, BitTorrent and BitTorrent DHT.
For FTP, EPSV and EPRT command support was added.  Enabling IPv6 DHT
requires several options, so please check out the usage example in man
page or wiki usage example page. By default, the asynchronous DNS
resolver does not handle IPv6 address. To work with IPv6 address, use
--enable-async-dns6 option.  aria2 now listens on both IPv4 and IPv6
socket for BitTorrent, its DHT and XML-RPC. aria2 uses same port for
both IPv4 and IPv6. The ability to add/remove BitTorrent tracker
announce URI was added.  The link error for
FallocFileAllocationIterator was fixed.

Please note that since 1.10.0 release, aria2 uses 1 connection per
host by default and has 20MiB segment size restriction. So whatever
value you specify using -s option, it uses 1 connection per host. To
make it behave like 1.9.x, use --max-connection-per-server=4
--min-split-size=1M. If you specify multiple hosts, aria2 will use
all of them and open multiple connections.

Changes
-------

 * Enter end game mode as soon as all pieces are assigned to peers to
   avoid substantial slow down at the very last stage of download.

 * Set max outstanding request size of BitTorrent download to 100. Set
   stepping to 6.

 * Added --bt-tracker and --bt-exclude-tracker option.  In
   --bt-tracker option, you can specify comma separated list of
   additional BitTorrent tracker's announce URI. These URIs are not
   affected by --bt-exclude-tracker option because they are added
   after URIs in --bt-exclude-tracker option are removed.  In
   --bt-exclude-tracker option, you can specify comma separated list
   of BitTorrent tracker's announce URI to remove. You can use special
   value '*' which matches all URIs, thus removes all announce
   URIs. When specifying '*' in shell command-line, don't forget to
   escape or quote it. Added bt-tracker and bt-exclude-tracker to -i
   list option.

 * Listen both IPv4 and IPv6 for BitTorrent protocol.

 * Listen both IPv4 and IPv6 for xml-rpc request.

 * Added IPv6 DHT. Added --dht-entry-porint6, --dht-file-path6,
   --dht-listen-addr6 and --enable-dht6 option.  IPv6 DHT is disabled
   by default. To use IPv6 DHT, you need to use --enable-dht6 and
   specify a global unicast address to --dht-listen-addr6.  IPv6 DHT
   is highly experimental.

 * Added support for peers6 key in tracker response.  Added added6,
   added6.f and dropped6 in ut_pex.

 * Add only gracefully disconnected peer to ut_pex dropped list.  Add
   incoming dropped list to PeerStorage.

 * Don't use pre-calculate hash value when end-game mode.  Throw
   exception if bad piece is received.

 * Added bittorrent::packcompact() which replaces
   bittorrent::createcompact() and supports IPv6 addresses. Rewritten
   bittorrent::unpackcompact() and bittorrent::extractPeer() to
   support IPv6 addresses. Fixed added.f flags in ut_pex.

 * Added --enable-async-dns6 option. This option enables IPv6 name
   resolution in asynchronous DNS resolver. This option will be
   ignored when --async-dns=false.

 * Use hostname of original URI when counting hostname in
   inFlightRequest.

 * Fixed the bug that
   AdaptiveFileAllocationIterator::getCurrentLength() does not return
   updated allocated bytes.

 * Added FTP EPSV and EPRT command support. aria2 issues these
   commands when address family of local socket is AF_INET6.

 * Rewritten check for fallocate using AC_COMPILE_IFELSE.

 * Fixed the bug that HAVE_SOME_FALLOCATE gets undefined if fallocate
   is not available even if posix_fallocate is available. This causes
   FallocFileAllocationIterator.cc is out of compile targets and
   linker error.



aria2 1.10.0
============

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

This release adds an option to limit the number of connections to the
same host in each download. aria2 now chooses server which is least
used in aria2c instance. This release also adds Chromium cookie
support and HTTP only conditional download support which is download
file only when the local file is older than remote file.  aria2 now
can handle %2F in FTP URI properly. HTTP/1.1 chunked decoder was
fixed. For Linux, aria2 uses fallocate by default if it is usable.

Changes
-------

 * Metadata download may take very long time. If URIs are available,
   give up metadata download in at most 30 seconds.

 * Added --on-bt-download-complete=COMMAND option.  For BitTorrent, a
   command specified in --on-download-complete is called when download
   completes and seeding is over. On the other hand, this option set
   the command to be executed when download completes but before
   seeding.

 * Added --conditional-get option.  Download file only when the local
   file is older than remote file.  This function only works with
   HTTP(S) downloads only. It does not work if file size is specified
   in Metalink. It also ignores Content-Disposition header. If a
   control file exists, this option will be ignored. This function
   uses If-Modified-Since header to get only newer file
   conditionally. When getting modification time of local file, it
   uses user supplied filename(see --out option) or filename part in
   URI if --out is not specified.

 * FeedbackURISelector now tries to select URI whose host is least
   used in aria2 globally.

 * Added --min-split-size=SIZE option.  aria2 does not split less than
   2*SIZE byte range.  For example, let's consider downloading 20MiB
   file. If SIZE is 10M, aria2 can split file into 2 range [0-10MiB)
   and [10MiB-20MiB) and download it using 2 sources(if --split >= 2,
   of course).  If SIZE is 15M, since 2*15M > 20MiB, aria2 does not
   split file and download it using 1 source.

 * Added --max-connection-per-server=NUM option. The default value of
   NUM is 1. This option limits the number of connections allowed to
   one server for each download. This means when NUM is 2 and 1 URI is
   provided, even if you specified -s 5, aria2 establishes 2
   connections.

 * Set end byte in Range header if start byte > 0 to get more chance
   to pool socket.

 * Fixed ChunkedDecoder. It does not read trailer and final CRLF.

 * Send each CWD component of FTP URI in separate CWD command as
   described in RFC1738.

 * Fixed the bug that aria2 cannot handle %2F in FTP URI properly.  If
   directory component starts with %2F which percent-encode of '/',
   client should issue CWD to absolute path, but aria2 does not do
   that. It just issues relative path and download fails.

 * Added Chromium/Google Chrome Cookies file support. Thanks to
   gotrunks for original patch.

 * When allocating disk space, for Linux system with fallocate()
   system call, first check file system supports fallocate.  This just
   run fallocate with small chunk and see it succeeds or fails.  If it
   succeeds, use fallocate() to allocate entire file otherwise fall
   back to traditional slower method: writing zeros. This behavior is
   enabled in --file-allocation=prealloc, so this is enabled by
   default for most modern Linux.
