CHANGELOG.md

@@ -3,12 +3,14 @@
 Bug fixes:
 
 * Sharing for thread-safety of objects is now triggered later as intended, e.g., when a second `Thread` is started.
+
 Compatibility:
 
 * Exceptions from `coerce` are no longer rescued, like MRI.
 * Implemented `Integer#{allbits?,anybits?,nobits?}`.
 * `Integer#{ceil,floor,truncate}` now accept a precision and `Integer#round` accepts a rounding mode.
 * Added missing `Enumerable#filter` and `Enumerator::Lazy#filter` aliases to the respective `select` method (#1610).
+* Implement more `Ripper` methods as no-ops (#1694).
