2.4.3

CHANGES:

Fixed

• Fix missing katex headers (@panglesd, #1096)
• Allow ][ in code blocks, fixing issue #1137 (@Julow, #1149)
  This was interpreted as "code blocks with result", which now mandates a
  delimiter: {delim@lang[ code ]delim[ result ]}
• Fix misprinting of type variables from ml files for OCaml 4.14 and later
  (multiple occurences of the same type variable could be named differently)
  (@Octachron, #1173)
