 ## [Unreleased]
 
 
+## [1.2.0] - 2023-08-09
+
+New:
+- Support for specifying custom Compose compiler versions. This will allow you to use the latest
+  version of Molecule with newer versions of Kotlin than it explicitly supports.
+
+  See [the README](https://github.com/cashapp/molecule/#custom-compose-compiler) for more information.
+
+Fixed:
+- Ensure frame times sent by `RecompositionMode.Immediate` always increase. Previously,
+  when targeting JS, the same frame time could be seen since the clock only has millisecond
+  precision. Since the frame time is in nanoseconds, synthetic nanosecond offsets will be added to
+  ensure each timestamp is strictly greater than the last.
+- Perform teardown of the composition on cancellation within an existing coroutine rather than in
+  a job completion listener. This ensures it executes on the same dispatcher as the rest of the
+  system, rather than on the canceling caller's thread.

+### Custom Compose Compiler
+
+Each version of Molecule ships with a specific JetBrains Compose compiler version which works with
+a single version of Kotlin (see [version table](#Usage) above). Newer versions of the Compose
+compiler or alternate Compose compilers can be specified using the Gradle extension.
+
+To use a new version of the JetBrains Compose compiler version:
+```kotlin
+molecule {
+  kotlinCompilerPlugin.set("1.4.8")
+}
+```
+
+To use an alternate Compose compiler dependency:
+```kotlin
+molecule {
+  kotlinCompilerPlugin.set("com.example:custom-compose-compiler:1.0.0")
+}
+```
