Changes:

• Added GUI name references to some more Kad queries [tHeWiZaRdOfDoS]
• Resolve shared shell links has now its own option in the extend dialog instead beeing a preferences.ini only option
• Added the preferences.ini only option "FileBufferTimeLimit" ("eMule" section) which lets you set the maximum seconds before flushing the buffer of downloading files (default 60)
• When another client requests to view your shared files and directories (and you allow it), eMule will now attach only the directory names (or relative paths if it is a shared subdir) instead the full path for privacy reasons
• On a fresh eMule installation, several less important list columns are now hidden by default to avoid overloading the interface
• Slightly increased the max. button size of the maintoolbar
• You can no longer share single files within unshareable directories (like your temp dir)
• Dates shown in the download list have their own time format setting ("DateTimeFormat4Lists" in preferences.ini) which is by default more compact than the old one
• Added a column to the download list which shows the date when the download was started
• Kad routing query contacts are checked against the routing table
• Kad no longer allows more than 2 IPs from the same subnet within one routing query reply (except on LANs)
• The Kad UDP firewalltest now asks several clients for its external port, avoiding to get a wrong "Open" state on NATs which change the source port on each request but behave like a Full-Cone otherwise
• Kad now rechecks incoming search results against the filters used for a search and drops all results which fail (which should only happen for buggy clients and spam results)
• Some data (like the AICH hashset, statistics, metadata etc) from known/downloaded files which were not shared within the last month now gets purged to save ressources and avoid an unlimited growth of the known.met files
• If you want to avoid this purging for some reason you can put "PartiallyPurgeOldKnownFiles=0" in the "eMule" section of your preferences.ini
• When sorting lists for file types, eMule now further sorts by extension when the filetype is the equal
• On simple search queries Kad now rearrenges the used keywords itself and uses the longest keyword to determine which node to ask. This reduces the search load on common used keyword nodes like "and", makes such keyword a less viable target to attackers and allows users to do a search which begina with a short keyword like "An eMule"
• Kad file/source search answers now try to avoid using fragmented packets, making it more compatible to zealous firewalls routers which block those (effect increases as more nodes update to this version)
• The Webinterface port can now also be forwarded by UPnP (Options->Webinterface)
• The UPnP mappings are checked and refreshed if needed before Kad firewallchecks, after waking up from suspend and on smart lowid detection when connecting to servers
• The allowed comment size has been increased to 128 characters
• Added support for Windows 'Address Space Layout Randomization' security feature (Windows Vista)
• Made sure a received Kad routing answer doesn't contain more contacts than requested [Xin Sun]

• Added reading of meta data for WAV files to "Content" page of File Details dialog.
• Added publishing of ED2K specific meta data for WAV and WMA files.
• Added columns for ED2K meta data to Shared Files window.
• Added reading of meta data for Windows Media files to "Content" page of File Details dialog.
• Added yet another method to determine whether the MediaInfo library is installed.

• Fixed some redrawing/resizing problems and reduced flickering in several main eMule windows.
• Removed the "Search with Unicode" search option - searches are always with Unicode.
• Removed support for *.met file backward compatibility with non-Unicode eMule versions.

• Added verifying of the 'connected' state for all shared directories when updating the "Shared Files" tree view by using the 'Reload' button.
• Removed restrictions for sharing drives 'A:' and 'B:'.
• 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
• The Beta versioncheck will now point to a seperate website instead the standard versioncheck (which doesn't works for betas)
• Update MiniUPnPlib to the latest version
• Updated libpng to the latest version
• The archive preview tab has now a context menu to update the contents as replacement for the "Update" button
• eMule now selects the default color of the system icon tray speedbar depending on the color of your taskbar icon area, to avoid show a dark/bright bar on a dark/bright background

• 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
• 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! :)
• 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
• 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.umn.edu/~hopper/kad.pdf]
• 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
• Added preferences.ini-only option "KeepUnavailableFixedSharedDirs" ("eMule"-Section) which lets eMule keep shared directories on fixed drives even if they are not found anymore
• 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)

• The new tabs in the shared files dialog can be closed or restored by an arrow button on the right side
• 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
• 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
• 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.
• 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)
• Replaced the (defunct) Filedonkey search option with the ContentDB
• Updated used libraries, like miniupnpc making UPnP compatible with more devices
• Optimized internal handling of the AICH hashes

Features:

• When corrupted part.met files are detected, eMule now automatically tries to use the part.met.bak files instead
• You can now also share single file and directories by Drag&Drop - simply drag them from (for example) the Windows Explorer into your Shared Files list
• You can now share and unshare single files in the shared files window by chking/unchecking the files in the "All directories" tree. Downloading files and files in the incoming directory cannot be unshared
• Added support for Windows 'Heap Corruption Detection' security feature (Windows Vista)
• Added support for preview the content of ISO files. (file details->content)
• Added support for Windows 'Data Execution Prevention' security feature (Windows XP SP2 / Windows Vista)
• Added auto-sizezing of column widths to all list views (double clicking on column divider will size the column width appropriatly)
• Added Options->Extended->Resolve shell links which lets eMule share 'linked' files (Windows Explorer shortcuts). This way one can also share single files within unshared directories.
• Added support for previewing self extracting RAR archives.
• Added: Downloaded files are marked in the same way as by 'Internet Explorer' which leads to showing a warning message from 'Windows' when opening potential malicious files (for Windows XP SP2 or later).
• Added: Opening DRM protected files shows a warning message to prevent accidental opening of a web browser and navigating to malicious sites.
• 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
• Windows 7: Added global progress bar in the eMule taskbar button, progress colors: green when downloading, red when a download is errorous, yellow otherwise
• Windows 7: When hovering over the eMule taskbar button (connect/disconnect/throttle/unthrottle/open preferences)
• Windows 7: Overlay icon on the eMule taskbar button indicating active up- and downloads (disabled by default, enable by ini entry "ShowUpDownIconInTaskbar=1").
• Tweaked uploadcode to significantly increase the possible uploadspeed per slot especially on LANs, making eMule more suitable for those
• Changed Kad to work better in small LANs.
• 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 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
• 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
• 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)
• Reworked the upload code and implemented better IO handling, which allows eMule to more efficiently handle high bandwidth lines, utilizing the full upload capacity (which means others can download faster)
• Optional HTTPS protocol in Web Interface will protect remote control sessions
• Added: mp4, mkv and ogg quick verification (thanks to Enig123)
• IRC tabs - each tab now has a separate input and autocomplete
• Added magnet links, basic parsing (file name, length, hash, AICH hash and sources)
• Certificates for HTTPS may be created in Options
• Support for searching collections in the web interface
