More search results returned

All previous versions created a database of keywords from the names of shared files. This did not include keywords from folder names with a file and did not include any 1 or 2 character keywords. Also a search for "believ" would not return any results for "believe" or "believing".

These problems have been fixed although the new system may be slower particularly when nothing matches the search query.

In addition, search queries containing anything more than ASCII characters are now handled case insensitively. This requires both the remote encoding for the hub to be set correctly and for your filenames to use your local system's encoding.

Switching active/passive mode

Switching between active and passive mode no longer requires restarting valknut. Actually it already worked except your tag may not have been updated and of course the dialog told you to restart.

StrongDC compatible encryption

Encrypted transfers are now possible with StrongDC and compatible clients. This new system is enabled automatically when support is detected and the transfer certificate and key in the options dialog security tab have been filled in (press the generate button, requires the openssl utility program).

The old valknut specific method of encrypting transfers has been disabled by default since it can not encrypt the initial protocol commands exchanged.

An additional incoming TCP port is required for active mode.

Encryption will increase CPU usage, and is not particularly useful for avoiding traffic shaping, which is normally based on prioritising certain services and lowering the priority of everything else.

Partial list uploads

Partial file listings, which list just the contents of the requested directory, can now be uploaded.

dclib bug fixes

• 0.3.18 had a bug on hubs that do not support UserIP2, causing the port number to be appended twice to the address sent in a connection request.
• The auto search did not reset the countdown on user searches, possibly resulting in too frequent searches which may violate hub rules.
• Problems due to hub name vs hub IP address identification e.g. a download from search could not find an open filelist transfer for that user started from the user list.

Search window improvements

• The "exact size" option was removed because no DC client supports this and using it will return no results.
• The search log is now used, by both user and automatic searches.
• Search result grouping is now remembered and done as results are received.
• More than one search window is now allowed. However only one search can be running at a time, even if you try searching different hubs.

User list icon changes

• The blue loop around an icon indicates support for StrongDC compatible encrypted transfers.
• The icon for LAN speeds has changed.
• The old LAN speed icon is now used to indicate the "Server" flag.
• The "Fireball" icon may be shown for users with that flag.

The server and fireball flags are probably related to uptime or upload rate and are unlikely to be used by most DC clients. Like the description, speed or email fields there is no way to verify the information anyway.

valknut fixes / improvements

• Qt3: fix whitespace being added after the cursor on tab nick completion.
• Lots of dialogs appeared detached from the main valknut window creating an additional entry in your panel.
• Browsing your own filelist and the file transfer info window no longer block the rest of the user interface.
• The option to enable/disable the tray icon was moved to the view menu.
• Valknut will now use your default desktop web browser (via "xdg-open" or Qt4) on links clicked in chat. A custom browser can still be set.
• Qt4: An option to use the "tabs for everything" style instead of the classic MDI interface was added. Requires Qt 4.4, and works if compiled against Qt 4.3 but then run under Qt 4.4.
• Opening new hubs will no longer un-maximize other windows.

Packaging related changes

• Building dclib: requires zlib-devel bzip2-devel libxml2-devel and (optionally) openssl-devel.
• The dclib-devel package requires openssl-devel (unless --disable-ssl was used) but no longer requires libxml2-devel or zlib-devel.
• The shared library is now libdc.so.1 and the number will usually be incremented for every release. Although all previous versions produced libdc.so.0 there was not usually any compatibility.
• Building valknut: requires dclib-devel and qt-devel (and all their deps) but openssl-devel, libxml2-devel, bzip2-devel are not directly required.
• Valknut now installs valknut.desktop into prefix/share/applications and icons of various sizes as prefix/share/icons/hicolor/<size>/apps/valknut.png.
