Notepad3 version 4 build 992 released

By | May 14, 2018

We released Notepad3 version 4 build 922 two days ago. To say that this post is overdue, is an understatement. Well, rather late than never. In this release we’ve made many changes and fixed a lot of bugs. Notepad3 is maturing steadily and the support is amazing. Furthermore, the developers, testers and users are amazing people to work with. 🙂

We removed automatic updates, due to a permanent error in the way wyUpdate works. It does not look like it is actively being developed and the only solution is to run it over an insecure http connection. However, currently in development; automatic updates will be replaced with an administration tool that can be installed alongside Notepad3 that will be able to check for updates. Other notable changes include; a method to remove duplicate lines, focused view, dynamic status bar configuration, a menu entry for switching to high DPI tool bar buttons and a doc tail chasing function.

Notepad3 version 4.8.512.992

Notepad3 Roadmap

Because Notepad3 is being developed, tested and maintained by volunteers with limited time, the features below could take months to complete. Therefor, please be patient and we promise to get everything done in good time.

  • Notepad3 administration tool. It will install alongside Notepad3 and is for; advance configuration ([settings2]), theme management, checking for updates and command line tools for advance users.
  • New themes and tool bar buttons sizes.
  • Multilingual support according to Microsoft’s MUI model, where the language resources are maintained in a separate .dll.
  • Adapting the new Scintilla experimental large file (greater than 2GB) support.

    Improving the speed for large file, please!
    It is difficult to drag the scrollbar to the end of a large file (above 10MB). why?

  2. Leslie Lespes

    Why with this new version undo only work with one character at the time. If I cut a string of 80 characters long undo restores one character at the time.
