+## [2.3.0](https://github.com/kevin-lee/effectie/issues?q=is%3Aissue%20is%3Aclosed%20milestone%3Av2-m5) - 2025-12-14
+
+
+## New Features
+
+* Add `OnNonFatal[F[*]]` (#684)
+
+  `OnNonFatal[F[*]]` is to do something when `F[A]` actually contains an error.
+
+  e.g.)
+  ```scala
+  val fa: F[A] = ...
+
+  OnNonFatal[F].onNonFatalWith(fa) {
+    case SomeError(ex) => effectOf(println("ERROR!"))
+  }
+
+  // It prints out `ERROR!` if fa contains an error.
+  // If not, it does nothing.
+  ```
+
+* Add `syntax` for `OnNonFatal[F[*]]` (#689)
+
+  ```scala
+  import effectie.syntax.all._
+
+  val fa: F[A] = ...
+
+  fa.onNonFatalWith {
+    case SomeError(ex) => effectOf(println("ERROR!"))
+  }
+
+  // It prints out `ERROR!` if fa contains an error.
+  // If not, it does nothing.
+  ```
+
+## Changes
+
+* Update `CanRestart` to take `F[A]` as a by-name parameter (#685)
+
+  From
+  ```scala
+  trait CanRestart[F[*]] {
+    def restartWhile[A](fa: F[A])(p: A => Boolean): F[A]
+
+    def restartUntil[A](fa: F[A])(p: A => Boolean): F[A]
+
+    def restartOnError[A](fa: F[A])(maxRetries: Long): F[A]
+
+    def restartOnErrorIfTrue[A](fa: F[A])(p: Throwable => Boolean): F[A]
+  }
+  ```
+  To
+  ```scala
+  trait CanRestart[F[*]] {
+    def restartWhile[A](fa: => F[A])(p: A => Boolean): F[A]
+
+    def restartUntil[A](fa: => F[A])(p: A => Boolean): F[A]
+
+    def restartOnError[A](fa: => F[A])(maxRetries: Long): F[A]
+
+    def restartOnErrorIfTrue[A](fa: => F[A])(p: Throwable => Boolean): F[A]
+  }
+  ```
