I am pleased to release version 4.45 of MUSHclient. See the release notes for more details.

Improvements

• Fixed a few bugs
• Added new plugin callbacks: OnPluginListChanged, OnPluginMouseMoved
• Added extra functionality to miniwindows for detecting mouse movements
• Miniwindows can now hide the mouse cursor (pointer) completely
• Upgraded PCRE (Perl Compatible Regular Expression) support from version 7.2 to 8.0
• Upgraded PNG support from version 1.2.35 to 1.2.41
• Upgraded SQLite3 support from version 3.6.16 to 3.6.21
• Upgraded zLib support from version 1.1.3 to 1.2.3
• Added more selectors to GetInfo and GetPluginInfo
• Added Lua functions scan_dir and shuffle to the commas.lua module
• Assorted minor scripting improvements
• Some documentation improvements

Caution: There have been a significant number of changes to inbuilt libraries (PCRE, PNG, SQLite, zLib) which may conceivably break existing behaviour. This should not happen, however it is possible that some compilation option was overlooked when migrating the old libraries to the new ones. This version of MUSHclient (4.45) is intended for plugin authors, scripters, and other experienced users who may want to try out the new features.

Unless any of the existing bugs are troubling you, or if you need any of the new features, you are advised to stay at your current version for now (4.43 or 4.44 should be reliable).

If you choose to try this version please make backups (copies) of your MUSHclient folder, and your world files, and plugins. Be prepared to revert to the previous version if necessary.

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.

If you do an md5sum on mushclient445.exe you should get this result:

f0b3406d30f97d71270a1d2fab1c714c

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

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.

Warning about upgrading from versions prior to 3.21

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 about 5 years ago, so people who have recently installed MUSHclient should not have any problems.
