aria2 に似たアプリケーションはいくつか存在しますが、以下の 2 点 において aria2 は差別化されます: (1) 複数のソース (http/ftp そして BitTorrent) からダウンロードで きる。 (2) aria2 に URL のリストを与えた場合、それらを一つ一つ逐次的にダウンロー ドするのではなく、複数並列でダウンロードすることができます。一つ ずつダウンロードを待つ必要はないのです。これにより aria2 は与え られた帯域をめいいっぱい使用して高速なダウンロードを実現します。
ファイルをHTTP(S)/FTPとBitTorrentの両方から同時にダウンロードする機能を持っています。HTTP(S)/FTPからダウンロードしたデータは、BitTorrentネットワークにアップロードされます.
信頼性 という意味でもっともすぐれたHTTP(S)/FTPダウンロードユーティリティ です。なぜなら、Metalink のチャンクチェックサムをサポートしており、 BitTorrentのようにダウンロードした部分部分のチェックサムを照合す る機能をもつからです。チェックサムが違っていればその部分だけダウ ンロードすればよいのです。従来のようなファイルをすべてダウンロード してからチェックサムをとり、間違っていれば全部ダウンロードしなおすことと較べてください。 その差はファイルサイズが大きくなるにつれて明らかです。
This release fixes the bug that active downloads are not saved with --save-session-interval and the bug that aria2 hangs when size of download result exceeds its maximum. BitTorrent UDP tracker support was added. If the filename specified using --save-session ends with ".gz", aria2 stores the session file in gzipped form. The -i option can handle this gzipped file as well as plain text file. 1.15.2 based Portuguese translated manual was added.
* Make configure argument meaning more consistent and obvious.
Most other software uses --disable/--without for features it does
build or at least check by default.
Change aria2 configure options so that:
* --enable-*: do not build by default, unless --enable specified
* --disable-*: check and build by default, unless --disable specified
* --with-*: do not use by default, unless --with specified
* --without-*: check and use by default, unless without specified

* Bring back datetime in console log
* Run checksum check if -V and -c are used and file is completed
With -c option, aria2 can continue download after the existing file
position. If it is not completed, then after completion aria2 runs
checksum checking if available. But if existing file has already
been completed, then CreateRequestCommand exits without issuing
checksum checking. And aria2 treats it download error because it
needs checksum verification but it has not been done. This change
fixes this by properly checking download state and issue checksum
checking before CreateRequestCommand.
* Support for gzipped -i and --save-session
Saved sessions may very large, as in hundreds and even thousands of
megabyte when dealing with large queues. Add support to save and
reload sessions to gzipped files, when libz is available.
The session serializer will output gzipped contents when the file
ends with .gz, while the input file reader (UriListParser) will
accept whatever is thrown at it.

* Do not use a virtual varargs function
This stuff breaks in some compiler (configurations)

* Check for sys/signal.h and/or signal.h
mingw-w64 does not actually have sys/signal.h, while OSX currently
has a broken signal.h Better check the presence of both and use
sys/signal.h if present, else signal.h

* Do not reference RequestGroups longer than necessary
There is an initial vector of SharedHandle<RequestGroup> to seed the
DownloadEngine. This vector was however kept alive via main.cc ->
MultiUrlRequestInfo up until the program exits, hence effetively
leaking all initial RequestGroups and associated object instances.
Hence, as a matter of dirty-workaround, drop the contents of that
initial vector as soon as it is not required any longer.

* Fix infinite loop when size of downloadResults_ exceeds maxDownloadResult_
* Support BitTorrent UDP tracker
It shares UDP listening port with IPv4 DHT. At the moment, in order
to enable UDP tracker support, enable IPv4 DHT.
* Show correct end byte in error message when HTTP response range is not ok
Previously, unless HTTP pipelining is enabled, end byte in that
message is always 0. With this change, it shows correct end byte
sent to the HTTP server.
* Add Portuguese manual
This translation is based on aria2 version 1.15.2 manual.
