The $0D $0A sequence dates back to the Teletype Model 33 terminal, one of the first terminals to use ASCII. Traditionally, MS-DOS and Windows have used the same newline as Digital Research's CP/M: $0D $0A. Mac OS X 10.0 through 10.11 and macOS 10.12 to present use the same newline as UNIX: $0A. Mac OS 1 through 9 use the same newline as ProDOS on the Apple IIe: $0D. Microsoft has thoughtfully provided an out for Windows users counting on the app's past inflexibility: the new behavior can be undone with a registry key change. But it will retain the formatting of the files it opens so users will be able to view, edit and print text files with non-Windows line ends. Notepad will continue to output CRLF as its EOL character by default. Relief arrives in the current Windows 10 Insider Build. Opening a file written on macOS, Mac OS, Linux, or Unix-flavored computers in Windows Notepad therefore looked like a long wall of text with no separation between paragraphs and lines. Modern macOS, since Mac OS X, follows the Unix convention. For old-school Mac OS, the EOL character is just Carriage Return (CR, , 0x0d) and for Linux/Unix it's just Line Feed (LF, , 0x0a). The Register reports: Notepad previously recognized only the Windows End of Line (EOL) characters, specifically Carriage Return (CR, , 0x0d) and Line Feed (LF, , 0x0a) together. 'This has been a major annoyance for developers, IT Pros, administrators, and end users throughout the community,' Microsoft said in a blog post today.

Microsoft's text editing app, Notepad, which has been shipping with Windows since version 1.0 in 1985, now supports line endings in text files created on Linux, Unix, Mac OS, and macOS devices.
