Update pubspec and changelog and re-add abs-percent deprecation

+## 1.66.0
+
+* **Breaking change:** Drop support for the additional CSS calculations defined
+  in CSS Values and Units 4. Custom Sass functions whose names overlapped with
+  these new CSS functions were being parsed as CSS calculations instead, causing
+  an unintentional breaking change outside our normal [compatibility policy] for
+  CSS compatibility changes.
+
+  Support will be added again in a future version, but only after Sass has
+  emitted a deprecation warning for all functions that will break for at least
+  three months prior to the breakage.
+
+## 1.65.1
+
+* Update abs-percent deprecatedIn version to `1.65.0`.
+
+## 1.65.0
+
+* All functions defined in CSS Values and Units 4 are now parsed as calculation
+  objects: `round()`, `mod()`, `rem()`, `sin()`, `cos()`, `tan()`, `asin()`,
+  `acos()`, `atan()`, `atan2()`, `pow()`, `sqrt()`, `hypot()`, `log()`, `exp()`,
+  `abs()`, and `sign()`.
+
+* Deprecate explicitly passing the `%` unit to the global `abs()` function. In
+  future releases, this will emit a CSS abs() function to be resolved by the
+  browser. This deprecation is named `abs-percent`.
