eMule诞生于2002年，“电骡之父”是本名Hendrik.Breitkreuz 的德国人Merkur，他用mule（骡子，马骡）来作为这款客户端的名字，暗含对美国的电驴官方客户端edonkey（电驴，电子驴）挑战之意，如今电 驴官方从2006年开始早已不复存在，而电骡eMule八年来却成为了开源社区最神奇的一个软件，sourceforge中超过5亿次的下载量，来自世界 各地的程序员用自己的业余时间为它作出了贡献，还创造了数不清的mod，甚至连它的mod，比如emule xtreme，emule morphxt等都在sourceforge中排名前列，这不能不说是一个神奇。
而emule官方组织emule-project也始终如一的坚持秉承着“我们之所以创造eMule是为了快乐和知识，而不是为了金钱。”的理念，甚至已 经不再接受爱好者们的自愿捐款，仅靠销售一些吉祥物小骡子维持运转。昨天，eMule官方发布了新年以来的第一个正式版本，eMule 0.50a, 新版加强了aich hash验证，增强了LAN内部对KAD的利用，并且进一步改善了用户界面。新的eMule，新的网络分享时代。

Dear eMule users,
it has been a long ride, but now we are finally halfway there We are once again happy to present you a new shiny version: eMule 0.50a. Many small but nonetheless important fixes and changes were made, but the main features of this new version are:
Making eMules file verifying algorithm future proof by combining the ed2k hash with the AICH hash to identify and verify downloaded parts and files. This guarantuees that existing and newly found MD4 weaknesses will not affect eMules ability to deliver uncorrupted files in the future.
Several GUI improvements, like supporting new taskbar features of Windows7, easier access to download commands by adding a new toolbar, an improved shared files dialog and a brand new Kad graph to look and wonder at
Better usability in small LANs by adjusting Kad to such an environment and supporting highspeed uploads
And as always fixing bugs and adding other small changes
新增功能
以下是相对于eMule 0.49c新增的一些主要功能：
新增了一个用于下载的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……
eMule 0.50a
-----------------------
- Apr, 5. 2010 -
-----------------------
.: Added preferences.ini-only option "ExtraPreviewWithMenu" (eMule section) which makes eMule put the "Preview with" command into the root context menu rather than into the preview menu (only applies to extended controls with multiple preview programs set)
.: Added "Open preferences.ini" button to the extended options. Remember that you have to close eMule _before_ saving any changes if you want to edit any not preferences.ini-only settings
.: AICH hashs work properly in all collection types now
-----------------------
- Apr, 2. 2010 -
-----------------------
.: Added new ed2k link type: "ed2k://|search|[searchterm]|/" makes eMule start a search for the specified searchterm. Plugin for webbrowsers which make use of this will follow later
.: Fixed some minor bugs in the Kad graph
.: Fixed a possible bug with AICH recovery when downloading a searchresult which includes the AICH hash
