Here's the corresponding Changelog of the sass versions:

## 1.98.0

### Command-Line Interface

* Gracefully handle dependency loops in `--watch` mode.

### Dart API

* Add a `const Logger.defaultLogger` field. This provides a logger that emits to
  standard error or the browser console, but automatically chooses whether to
  use terminal colors.

### JavaScript API

* Fix a crash when manually constructing a `SassCalculation` for `'calc'` with
  an argument that can't be simplified.

* Properly emit deprecation warnings as text rather than `StringBuffer` objects
  when running in a browser.

* Emit colored warnings and other messages on the console when running in a
  browser.

## 1.97.3

* Fix a bug where nesting an at-rule within multiple style rules in plain CSS
  could cause outer style rules to be omitted.

## 1.97.2

* Additional fixes for implicit configuration when nested imports are involved.

## 1.97.1

* Fix a bug with the new CSS-style `if()` syntax where values would be evaluated
  even if their conditions didn't match.

## 1.97.0

* Add support for the `display-p3-linear` color space.

## 1.96.0

* Allow numbers with complex units (more than one numerator unit or more than
  zero denominator units) to be emitted to CSS. These are now emitted as
  `calc()` expressions, which now support complex units in plain CSS.

## 1.95.1

* No user-visible changes.
