Mitchell Hashimoto has published a proposal for OSC 7501, a new terminal escape sequence protocol that would let programs report status information like progress and running state directly to the terminal. The write-up explains the design and motivation, and developers are discussing the idea on forums like Lobsters, debating how terminals and command-line tools should communicate program state.

Discussion is growing around Ghostty, the terminal emulator created by Mitchell Hashimoto, after users noticed no new tagged releases since March 2025. On GitHub's release tags page, the last published version still dates from early spring, leading developers to wonder whether the project is slowing down, in a long development phase, or shifting to a different release model.
