4.21 – Mudlet, made better.

This new release of Mudlet sees 47 new features added, 77 improvements, a whopping 207 bug fixes, and 203 behind-the-scenes infrastructure changes.

The Mudlet development team is pleased to present version 4.21. This release places a strong emphasis on stability, which is reflected in the significant number of bug fixes and infrastructure updates. Since the last release the project has averaged seven code changes per day, highlighting the dedication of both the development team and the community to continuously improving Mudlet. Read on for a short rundown on some newly added games and features.

Reminder: Remember to enable automatic updates in the preferences so you get access to the latest important bug fixes.

Note: Mudlet no longer supports 32-bit Windows builds on Windows. If you are using an older 32-bit build on Windows (check the About window to find out) you will need to uninstall Mudlet, then download the latest release and reinstall. All of your things still stay.

Multiple Note Tabs

Another handy addition to the notepad allows for multiple tabs. All tabs reopen each session and save automatically upon closing.

Hide Default Profiles

Want to tidy up all those unnecessary profiles cluttering your connection screen? We’ve added an option to hide the default profiles and only show those you have connected to or manually created.

Telnet Handler

Mudlet can now associate itself with telnet links allowing players to connect to MUD servers with a single click from browsers or other applications, which means you can now click a link on the web to directly open up Mudlet! Here’s an example with Stickmud.

You may receive a once off popup on opening Mudlet this time asking you if you would like this to occur.

Mapper improvements

map label support to 3D mapper
hidden rooms
coloured room borders

Credits

Of course, none of this is possible without the huge amount of hours our volunteers donate to the project. Thanks to all testers (especially this release!), translators, wiki editors, patreons and support provided by our community on Discord! A special shout out goes to all of the coders who donated their time to the project.
