* 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.
