新增功能

以下是相对于eMule 0.49c新增的一些主要功能：

• 新增了一个用于搜索的eD2k链接类型：ed2k://|search|[searchterm]|/。点击链接，传送至eMule中之后，即可直接在eMule中搜索链接定制的文字。eMule官方团队接下来将进一步对此功能提供支持。
• 加强了Kad的功能。完善了查看KAD的图形界面，增强了小型LAN内部对KAD的利用，支持高速上传；
• 加强了AICH Hash验证系统。将eD2k Hash和AICH Hash相结合，以更好地验证文件，确保MD4的缺陷不会影响eMule使其发送损坏文件；
• 对preferences.ini设置文件其部分设置方式进行了更新；
• 进一步改善了GUI用户界面。比如Windows 7中的新型任务栏，加入新的下载命令工具栏，共享文件时的全新的提示；
• 一些小更改和Bug修正；
• 等等……

-----------------------
- Mar, 3. 2010 -
-----------------------

- Mar, 1. 2010 -
-----------------------

-----------------------
- Feb, 19. 2010 -
-----------------------
.: Fixed a bug in Kad which would not enforce the search tolerance in certain cases
.: Changed Kad to work better in small LANs. If Kad detects it is running on a LAN (only LAN IPs in the routing table), it will assume beeing open and not behind a NAT/Router without trying to verfiy (which would fail in a small LAN),
and also doesn't enforces several security features like flood detection for LAN IPs. Now even a small Kad LAN of 2 nodes works well without any setup issues
(To create such a Kad LAN, make sure all clients have Options->Extended->"Filter server and client LAN IPS" disabled, delete the existing nodes.dat if necessary, go to the Kad dialog and enter the IP+Port of one other client (which is either connected or in connecting mode for Kad) to the bootstrap box - done)
-----------------------
- Jan, 25. 2010 -
-----------------------
.: The connection wizzard is no longer shown after finishing the first start wizzard (it's deprecated)
.: The first start wizzard is only shown on first starts and no longer after updates
-----------------------
- Jan, 21. 2010 -
-----------------------
.: Added a new graph to the Kad window, which lets you watch each Kad lookup in detail. For non-Devs this is just for fun, you don't need to worry about anything shown there. A detailed explanation of the graph can be found in the onlinehelp.
.: Added "Automatically show active searches" option to the context menu of the new graph which lets it switch to active lookups automatically (instead having to select it in the list). Now you can watch Kad working for hours without a click!
-----------------------
- Jan, 12. 2010 -
-----------------------
.: Added a new dockable toolbar to the transfer dialog. The buttons resemble the context menu options, but making them accessible easier and faster. The toolbar can be removed by right clicking on it and shown again by selecting context menue option of the downloadlist
-----------------------
- Jan, 10. 2010 -
-----------------------
.: The context menu in of the downloadlist allows now directly assign a file to a new category (instead of having to create it separately first)
.: The "Unassign" category context menu entry is now only available if a file actually has a category
-----------------------
- Dec, 7. 2009 -
-----------------------
.: Fixed missing setting saving after automatic adapting incoming folders of categories due to changed main incoming folder
.: Fixed a bug with overwriting the nodes.dat on times we actually don't want to write it [Nissenice]
.: Added a quick intermediate fix to make certain Kad lookups more reliable, improving the (search/source-) results in some cases [based on research from http://www-users.cs....hopper/kad.pdf]
-----------------------
- Nov, 28. 2009 -
-----------------------
.: Switched the eMule fileidentifiers from ED2k-Hash + Size to ED2k-Hash + AICH-Hash + Size. This means eMule is now using two hashing algorithms combined (based on MD4 and SHA1) to verify if a received part (and eventually the comlete files) is not corrupt
This change is necessary due to weaknesses in the MD4 algorithm and enables eMule to make sure to never complete a corrupt files for the next decade
All changes are backwards compatible, so no clients or files will be exluded from the network
.: AICH part hashsets are build out of existing AICH recovery hashsets, no rehashing is done
.: AICH verification is enabled when using an ed2k link with included AICH hash, or when searching and downloading a file from Kad when certain requirements are met (this will only start to work once the majority of nodes update)
.: The AICH hash can be seen in the search results list for kad searches if available
.: ed2k links can no longer be created without the AICH Hash, except if it is not available. ed2k links without AICH hash are considered deprecated, but are still accepted by eMule for now
-----------------------
- Nov, 15. 2009 -
-----------------------
.: The shared files list now shows files in root directories properly [dolphinX]
.: Fixed a bug with determining if the filesystem can handle large files when using categories [dolphinX]
.: Added preferences.ini-only option "KeepUnavailableFixedSharedDirs" ("eMule"-Section) which lets eMule keep shared directories on fixed drives even if they are not found anymore
.: Fixed minor memleak on kad searches [tHeWiZaRdOfDoS]
-----------------------
- Oct, 13. 2009 -
-----------------------
.: Added preferences.ini-only option "ForceSpeedsToKB" ("eMule"-Section), which will make eMule display all speed values in KB/s (instead of B/s to TB/s depending on the speed)
-----------------------
- Aug, 7. 2009 -
-----------------------
.: The shared files dialog has now a tab selector, letting you choose to view the statistics,(reduced versions of) the content, ed2k-link or metadata info for the selected file(s)
.: The statistics page on in the shared files dialog also has the following new entries: Popularity rank (ranking all your shared files based on Requests), On Queue (clients on queue for the selected file) and Uploading (current bandwidth used to upload the selected file)
.: The new tabs in the shared files dialog can be closed or restored by an arrow button on the right side
-----------------------
- Aug, 3. 2009 -
-----------------------
.: Fixed possible resource leaks in ZIP file decompression [tHeWiZaRdOfDoS]
.: Fixed sorting bug in Shared Files window [moloko+]
-----------------------
- Aug, 2. 2009 -
-----------------------
.: Fixed bug with downloading files via the built-in webserver [Stulle]
.: Fixed double/single click behaviour in search results window [tHeWiZaRdOfDoS]
.: Fixed bug in user hash validation [ilmira]
.: Fixed bug with space characters in ED2K URLs [moloko+]
-----------------------
- Jul, 25. 2009 -
-----------------------
.: Fixed a bug which made search tabs in certain cases invisible after you closed one
-----------------------
- Jul, 20. 2009 -
-----------------------
.: Cleand up options dialog a bit:
The following settings have been removed and are now preferences.ini-only: "Beeponerror", "DontRecreateStatGraphsonresize", "UpdateQueueListPref", "MessageFromValidSourcesOnly" (Section "eMule") and "EnabledDeprecated" (section "PeerCache")
.: The exit conformation messagebox has now a "Don't ask me again" option
.: Added "Pause on when preview possible" option to the downloadlist context menu. Only visible when "advanced mode controls" is enabled
-----------------------
- Jul, 09. 2009 -
-----------------------
.: Improved storing AICH hashsets after a download has finished - should be much faster now if you share many files
.: Sparse files are available on Windows7 again, Vista stays the only version were they are disabled
-----------------------
- Jun, 12. 2009 -
-----------------------
.: Added basic checks and user warnings for wrong operator usage (like using OR on the first keyword) in Kad. Earlier version just delivered wrong/incomplete results in such cases.
-----------------------
- Jun, 10. 2009 -
-----------------------
.: Fixed a bug in Kad with setting the proper searchkeywords when searching for exact phrases with quotes
.: Fixed a bug with rearranging quoted keywords on kad searches
-----------------------
- Jun, 2. 2009 -
-----------------------
.: Kad1 is no longer supported and we will no longer answer or request any packets from Kad1 nodes (the last eMule Kad1 version was release about 4 years ago)
-----------------------
- Mar - May 2009 -
-----------------------
.: eMule Summer of Non-Code

eMule本身是绿色软件，下载bin压缩包解压即可使用，但是考虑了很多初级用户，eMule官方也同时制作了安装包，文件名为：eMule0.49c-Installer.exe。而现在又针对Windows 7用户推出了这个第二个安装包Installer2。

Installer2安装包特别针对Windows 7制作，但是实际上任何版本Win用户均可使用。官方eMule下载页上，Installer2也已经替代了原来的Installer。

如果你已经配置好eMule，就不需要下载。如果你第一次使用eMule，那么强烈推荐下载Installer2安装包。

下载eMule0.49c-Installer2.exe

eMule 0.49c官方版本在Windows 7下可以正常运行，而真正基于官方0.49c版的mod也在Windows 7下运行正常，这些mod包括比如Xtreme v7.2 ，MorphXT v11.3，ScarAngel v3.2，X-Ray v1.7，Mephisto v2.2，StulleMule v6.2，EastShare v14.5等等，但是由于旧的安装包文件eMule0.49c-Installer.exe在Windows 7下使用以后还需要用户手动改变用户共享配置文件夹路经，所以eMule官方发布了这个新的安装包eMule0.49c-Installer2.exe来方便一些动手能力较弱比较依赖安装包指导的Windows 7用户。

另外由于最近继续有用户受骗，误入形如emule.com，emule.org等网址的钓鱼网站，eMule官方老大在论坛里再次提醒了大家，
