Update to 1.11.1

* aria2-metalink option is removed. This is enabled by default already.

Changelog:
aria2 1.11.1
============

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

This release fixes the bug that aria2 does not work on platforms which
have kqueue() system call due to invalid timeout parameter. The
--show-console-readout option was added. This option toggles the
appearance of console readout.

Changes
-------

* Added --show-console-readout option. This option toggles
  appearance of console readout.

* Fixed the bug that microsecond part of timeval overwlows in
  waitData(). This bug affects platforms which have kqueue() system
  call. Those systems are FreeBSD, OpenBSD, NetBSD and Darwin (Mac OS
  X).

aria2 1.11.0
============

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

This release adds JSON-RPC interface. The JSON-RPC and XML-RPC shares
same APIs. The JSON-RPC also supports JSONP. 2 new options were added:
--retry-wait and --async-dns-server. The downloads added by
aria2.addTorrent and aria2.addMetalink RPC method are now saved to the
file specified in --save-session option. The proxy options and related
environment variables now accept https:// and ftp:// scheme. This
release fixes the bug that causes segmentation fault when unpausing
downloads in some situations.  MinGW32 build now looks for USERPROFILE
and the combination of HOMEDRIVE and HOMEPATH to get user's home
directory and doesn't check permission of .netrc file.

Changes
-------

* Updated gettext to 0.18

* Added JSON-RPC support. --enable-xml-rpc was deprecated and
  --enable-rpc should be used instead.  Similarly, --xml-rpc-*
  options were replaced with --rpc-* options.  We are implementing
  JSON-RPC based on JSON-RPC 2.0 draft spec.

* Fixed rounding error in DownloadEngine::run(). This fixes the bug
  that executeCommand() with Command::STATUS_ALL is not called in
  every interval correctly because of rounding error in timer.

* Refresh buckets at DHT initialization without checking serialized
  time. Checking serialized time does not work if you stop aria2 as
  soon as it started DHT. The serialized time in dht.dat will be
  updated, but buckets are not updated and still old. When you
  restart aria2 again soon, it does not refresh buckets because
  serialized time is recent.

* Save downloads added by aria2.addTorrent or aria2.addMetalink in
  --save-session file.  Uploaded data are saved as file named hex
  string of sha1 hash of uploaded data plus extension(".torrent" for
  torrent and ".meta4" for metalink). For example,
  0a3893293e27ac0490424c06de4d09242215f0a6.torrent. The directory
  where these files are saved is specified by --dir option. These
  file paths are written in --save-session file.

* Fixed the bug that causes segmentation fault when unpause
  RequestGroup which has resolved BtDependency.

* Look for USERPROFILE and the combination of HOMEDRIVE and HOMEPATH
  to get user's home directory in MinGW32 build.  Usually HOME
  environment variable is defined in *nix like OSes, but not in
  Windows. So in MinGW32 build, if HOME is not defined, we also look
  for USERPROFILE and the combination of HOMEDRIVE and HOMEPATH.

* Fixed the bug that DownloadContext::basePath_ is not escaped.

* Added Date, Expires and Cache-Control response header field to RPC
  response.

* Added --async-dns-server option. This option accepts comma
  separated list of DNS server addresses used in asynchronous DNS
  resolver. Usually asynchronous DNS resolver reads DNS server
  addresses from /etc/resolv.conf. When this option is used, it uses
  DNS servers specified in this option instead of ones in
  /etc/resolv.conf. You can specify both IPv4 and IPv6 address. This
  option is useful when the system does not have /etc/resolv.conf and
  user does not have the permission to create it.

* Accept https:// and ftp:// in proxy options and environment variables.

* Fixed overflow in the calculation of progress percentage for file
  allocation and hash check when off_t is 32bit.

* Accept HTTP 304 reply as success when If-None-Match request-header
  field is specified using --header option.  When --conditional-get
  is used, --allow-overwrite is now required to overwrite existing
  file.

* Added aria2.removeDownloadResult RPC method.  The method signature
  is aria2.removeDownloadResult(gid).  This method removes
  completed/error/removed download denoted by gid from memory. This
  method returns "OK" for success.

* Use IP address of control connection to connect to the remote server in
  FTP passive mode.

* Don't check permission of .netrc file in MinGW32 build.

* Added --retry-wait option. This option was once existed in aria2
  but erased on 2009-09-20.  Now it is resurrected once again.  We
  choose 0 as default value for backward compatibility.  Now we retry
  HTTP download when remote server returns "503 Service Unavailable"
  if --retry-wait > 0. We also added error code 29:
  HTTP_SERVICE_UNAVAILABLE.

* Don't show metadata download and paused download in "Download Results".
