v1.1.0

Highlights:

• syntax
  • Parse [[ a = b ]] like [[ a == b ]], deprecating TsAssgn in favour of TsEqual
  • Add support for the -k, -G, -O and -N unary operators inside [[ ]]
  • Add proper support for ! in parameter expansions, like ${!foo}
  • Fix a couple of crashes found via fuzzing
• cmd/shfmt
  • Rewrite [[ a = b ]] into the saner [[ a == b ]] (see above)
