v0.19 — 2026-05-22

v0.19

This release was focused on wrapping up the plugin architecture, screensavers, a new port forwarding feature, and online documentation.

Plugins

Plugins are now hosted on GitHub (https://github.com/zimventures/cleat-plugins/) and include both UI plugins as well as a fun addition - screensavers! Plugins are quite flexible in how they're installed, deployed, updated, and applicable. I still owe a detailed API reference for what's available in Lua, but the cleat-plugins repo should serve as a good example for the time being.

Screensavers

Screensavers are just a different plugin type. You can write Lua and have your own plugin. Have fun with this!

Port Forwarding

Port forwarding is a handy feature for piping network traffic between a remote host and the local environment. In addition to setting up reusable port forwarding (on a per-connection basis), there is also a port browser to allow users to see which ports are open on the remote host for tunneling.

Online Docs

Online documentation was plumbed into the build framework and is available at now available at: https://zimventures.github.io/cleat/
