 ### Fixed
 
-- Restore `py.typed` marker so type checkers recognize `hcl2` (and `cli`) as typed packages. ([#298](https://github.com/amplify-education/python-hcl2/issues/298))
-- Parse heredocs with an empty body again. A marker immediately followed by its closing delimiter failed to match, and the lexer then ran on to a later delimiter, silently absorbing the attributes in between. ([#309](https://github.com/amplify-education/python-hcl2/issues/309))
-- Negative integer literals load as numbers again instead of `${-N}` expression strings, matching negative floats and the pre-8.x behaviour. ([#307](https://github.com/amplify-education/python-hcl2/issues/307))
-- `strip_string_quotes` no longer unquotes string literals nested inside expressions, which produced invalid HCL such as `${upper(x)}` from `upper("x")`. ([#310](https://github.com/amplify-education/python-hcl2/issues/310))
-- `strip_string_quotes` now resolves escape sequences, so the values it yields match what the option documents. Escapes naming a codepoint outside the Unicode range, or a lone surrogate, are preserved verbatim rather than raising. ([#308](https://github.com/amplify-education/python-hcl2/issues/308))
-- Parse files with CRLF (`\r\n`) line endings, including heredocs. A `\r` acting as part of a line ending is ignored, so a CRLF file reconstructs with LF endings; a `\r` that is content — inside a quoted string or a heredoc body — is preserved. ([#315](https://github.com/amplify-education/python-hcl2/issues/315))
-- Flattened heredoc bodies keep their trailing blank lines and trailing spaces instead of being right-stripped away, for both `<<MARKER` and `<<-MARKER`. The closing marker line's own indentation is still removed, and a blank line no longer cancels the `<<-` dedent. ([#316](https://github.com/amplify-education/python-hcl2/issues/316))
