Kitty is a terminal emulator that runs on Linux, macOS, and the BSDs, which is notable for its speed and features such as image support and advanced font handling. It is under active development; a recent major release adds a new level of mouse support. Here, we will look at some of those features and show how the program can also be used as platform for text-based applications. Kitty is free software, released under the GPLv3.

Version 1.97.0 of the Rust programming language has been released. Changes include using a new symbol-mangling scheme by default, support for denying warnings in Cargo, and an end to the practice of hiding the linker's output after a successful build.
