LibUV event will use the best available polling method on a system, kind
of like aria2 does already with the different *EventPoll
implementations.
However, libuv may support different/newer polling mechanisms; for
example on Windows it will use IO Completion Ports which are superior to
select() ;)
--save-session-interval option saves error/unfinished downloads to a
file specified by --save-session option every SEC seconds. If 0 is
given, file will be saved only when aria2 exits.
This option enables disk cache. If SIZE is 0, the disk cache is
disabled. This feature caches the downloaded data in memory, which
grows to at most SIZE bytes. The cache storage is created for aria2
instance and shared by all downloads. The one advantage of the disk
cache is reduce the disk seek time because the data is written in
larger unit and it is reordered by the offset of the file. If the
underlying file is heavily fragmented it is not the case.
To enable RPC over SSL/TLS, specify server certificate and private key
using --rpc-certificate and --rpc-private-key options and enable
--rpc-secure option. After the encryption is enabled, use https and
wss scheme to access RPC server.
This feature stops application when process PID is not running. This
is useful if aria2 process is forked from a parent process. The parent
process can fork aria2 with its own pid and when parent process exits
for some reason, aria2 can detect it and shutdown itself.
The code which detects whether or not given process PID is running is
contributed by Emmanuel Engelhart.
--enable-rpc and --rpc-* option instead.
--enable-xml-rpc and --xml-rpc-* option can be used but warning
message will be shown. The help tag #xml-rpc was replaced with #rpc.
Don't listen on IPv6 socket for BitTorrent, DHT, XML-RPC if
--disable-ipv6 is true.

Supported poll() for socket event notification. --event-poll can
take value "poll". Fixed the bug that timeout for
SocketCore::isReadable()/isWritable() is ignored when epoll is
used.

Throw exception if binding listening port is failed. Removed
RequestGroupMan::getInitialCommand(). Use
fillRequestGroupFromReserver() instead. Delete commands for
RequestGroup which has errors when it is being added.

Added experimental built-in HTTP server. Currently, when a
client accesses to the server, it responds with the current
download progress. By default, it is disabled. To enable the
server, give --enable-http-server option. To change the default
port number for the server to listen to, use
--http-server-listen-port option.
The response HTML is very simple and refreshes it self each 1
second. Because of this refresh, you see flicker in normal web
browser such as Firefox. I recommend to use console-based
browser such as elinks, w3m. To connect to the server, run
'elinks http://localhost:6800/' while running aria2. Please
replace port number '6800'(which is default) with your
preference.

Added --event-poll option to select the method for polling
events.
The available methods are "select" and "epoll". "epoll" is
available on Linux only. The earlier release has the compile
option to choose from these methods.

Added client certificate authentication for SSL/TLS.
Currently a private key must be decrypted for use with aria2.
If a user accidentally gives encrypted file to aria2 then
following thing happens:
If encrypted private key is given to aria2, it behaves
differently depending on the ssl library it uses. If aria2 built
with openssl then openssl prompts the user for password.
If aria2 build with gnutls then aria2 exists with error at start up.

is saved

Implemented download speed based URI selection algorithm.
Introduced new option --uri-selector.
If --uri-selector=feedback is given, aria2 uses download speed
observed
in the previous downloads and chooses fastest server in the URI
list.
Currently at most 10 URIs are considered to introduce
randomeness for
finding better servers. The speed is average download speed in
the
downloads.
On the other hand, if --uri-selector=inorder is given, which is
default,
URI is tried in order in URI list.
The usage text for the new option has not been written yet.

Eliminates the time lag between sequential downloads and
commands in
the same RequestGroup.
In old implementation, aria2 occasionally waits 1 seconds before
executing next command or RequestGroup.
This is really a waste of time, and new implementation
eliminates
this unnecessary time lag.

Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();
TODO: test/SharedHandleTest.cc needs more tests.
