 - Added highlighting of matching `do|fn` `end` pairs. This was added in v0.15.0 and reverted in v0.15.1. The previous attempt broke on `do:` and other atoms. This problem is now resolved with `constant.language.symbol.elixir` added to unbalanced scopes
 - Added highlighting of matching `<<` `>>` pairs. This was added in v0.15.0 and reverted in v0.15.1. The previous attempt broke on bitwise operators. This problem is now resolved with `keyword.operator.bitwise.elixir` and `keyword.operator.other.unbalanced.elixir` added to unbalanced scopes
 - Tests are no longer run with with `--raise` flag
