- kte refuses to start when stdin is not a terminal: piped bytes were executed as editor commands (C-k s plus a path writes a file), and after EOF the loop spun at full CPU with no way to quit. - The terminal frontend handles all pending input before drawing (a paste used to cost a frame and a full redraw per character) and redraws only after input, a resize or deferred opens, else once a second. The renderer caches, per row and buffer version, where the horizontally scrolled part of a line starts and the cursor's render column, instead of rescanning the line every frame. Idle CPU with the cursor at the end of a 20 MB line: one full core -> ~1%. - Buffers with a virtual name (+HELP+) are not journaled and saving one asks for a file name; it used to write ./+HELP+ and journal under that path. - Yank with a repeat count is capped at 256 MiB in total instead of reserving count x size bytes (C-u 1000000 C-y of a large kill). - Remove an overload clang reports as unused (-Werror on macOS).
