This is a bugfix release.
The v3.5.0 release included debugging code that caused messages to be written to the logs every second. While this wasn't catastrophic due to log rotation released earlier, it did cause unnecessary disk IO. Cleaning that up is the main reason for this release, and gotop should be much more quiet now. Other changes include
- The kitchensink layout was forgotten
- Safety check prevent uninitialized colorscheme registry use, which could cause crashes
- The readme includes instructions on where to put colorschemes and layouts
- Some enhancements for plugins which, since extensions hasn't been officially released, most people won't notice.
