I am pleased to release version 4.96 of MUSHclient. See the release notes for more details.


  • Changed the 256-ANSI colour cube to follow the Xterm model (with brighter colours) rather than the Netscape model (with even colours).
  • Added script function utils.colourcube. This lets you change back to the Netscape colour cube if you prefer.
  • Added plugin callback OnPluginDrawOutputWindow. This lets you do things (like update a miniwindow) at the moment the output window is being redrawn.
  • Modified graphical mapper to support mouse-over events for rooms.
  • Added new function "tooltip" to module mw.lua. This lets you easily draw a tooltip window.
  • Modified gauge.lua to add functions suggested by Fiendish, and also added a margin around the box drawn by draw_text_box, so that the text does not hit the edge of the box.
  • Fixed bug in WindowResize function where the resized window would lose its existing contents. Also amended the documentation which gave an incorrect example.
  • Fixed small bug in InfoBox.lua on advice of author, Willfa.
  • Upgraded libpng (the PNG library) from 1.5.14 to 1.6.15.
  • Upgraded SQLite from 3.8.7 to

You can download MUSHclient 4.96 now from ...

You are strongly advised to backup (make a copy of) your existing MUSHclient world files before upgrading. Just in case.

If there are any problems, please post messages to the Bug Reports, Suggestions, or General parts of this forum.

MD5 sum for the installer

If you do an md5sum on mushclient496.exe you should get this result:


The forum post a small script to sumcheck the MUSHclient download shows how you can write a small script in MUSHclient to do the sumcheck. It also lists some places you can download md5sum.exe to do the sumcheck (if this is the first time you have downloaded MUSHclient).

One way of doing an md5sum is to download the Installer_sumcheck plugin from the Plugins page (RH click that link and "save link as" to get the plugin). Then install the plugin (see the File menu -> Plugins) and type "md5sum" which lets you browse to the installer file, load it, and display the sumcheck.

Message about "Failed to load resources file"

Some users are reporting getting a message like "Failed to load resources file: C:\Programme\MUSHclient\locale\DE.dll - trying English file" when starting MUSHclient (the DE.dll part might be another language like FR.dll).

This will be because you have customized the "locale" of MUSHclient to other than EN (English). See the How to localize MUSHclient messages into other languages forum posting for more details about localization.

To fix this, find the directory you installed MUSHclient into (eg. "C:\Program Files\MUSHclient\") and then locate the subdirectory "locale". In that you will find a file en.dll. Copy or rename that file to match the missing file in the message (eg. copy en.dll to de.dll).

Alternative suggestion: Go into the File menu -> Global Preferences -> General, and change the field "Locale code" back to "EN" (English) and then it should look for EN.DLL next time.

Warning about Lua 5.1 upgrade (September 2006)

MUSHclient version 3.80 upgraded the Lua script engine from Lua 5.0.2 to 5.1.1. If you are upgrading to this version from an earlier version than 3.80, you should read Version 3.80 released - with Lua 5.1 script engine - this post has recommendations about what is required if you use Lua scripting or Lua plugins. Note: Since version 3.80 was released, the version of Lua has been upgraded. It is currently 5.1.4. Some versions (versions 4.49 to 4.52 of MUSHclient) may incorrectly report they are using Lua 5.1.1 when you open a world.

Warning about upgrading from versions prior to 3.21 (May 2002)

MUSHclient version 3.85 (onwards) no longer reads the old "binary" world files produced by versions prior to 3.21. For more information about this please read the forum post Versions 3.85 onwards no longer support world files created prior to version 3.21 - this post has recommendations about how to upgrade your world files if you are upgrading from a version earlier than 3.21.

Note that version 3.21 was released quite a few years ago (May 2002), so people who have recently installed MUSHclient should not have any problems.

Source code

The source code for this version is available from GitHub:


You can directly download the source from the Downloads page (http://github.com/nickgammon/mushclient/downloads), or preferably install Git and use the appropriate commands to clone or pull the source. For some suggestions about getting the source from Git see MUSHclient source being made available on GitHub forum posting.

If you install Git, subsequent downloads (of new versions) will be much faster as it only needs to download the changes, not the whole source. Also by using Git you can find out exactly what has changed from version to the next.
