CHANGELOG.unreleased.md

• CLI: Fix CI detection to avoid unwanted TTY behavior ([#5804] by [@kachkaev])

  In Prettier 1.16.0 and 1.16.1, --list-different and --check logged every file in some CI environments, instead of just unformatted files. This unwanted behavior is now fixed.

• HTML: Do not format non-normal whitespace as normal whitespace ([#5797] by [@ikatyang])

  Previously, only non-breaking whitespaces (U+00A0) are marked as non-normal whitespace, which means other non-normal whitespaces such as non-breaking narrow whitespaces (U+202F) could be formatted as normal whitespaces, which breaks the output. We now follow the spec to exclude all non-ASCII whitespace from whitespace normalization.

  (· represents a non-breaking narrow whitespace)
