+# 1.25.0
 > __BREAKING CHANGES__
 >
 > - FIX: Corrected the `Installation` property `appVersion` to be the build version instead of the version name. This aligns the property with its equivalent in the Parse iOS SDK. See [#902](https://github.com/parse-community/Parse-SDK-Android/issues/902) for details. Thanks to [Manuel Trezza](https://github.com/mtrezza).
 - Added RxJava module to transform `Task`s into RxJava types.
 
-### 1.24.2
+# 1.24.2
 - FIX: Fixed naming collission bug due to integration of bolts-tasks module. See [#1028](https://github.com/parse-community/Parse-SDK-Android/issues/1028) for details. Thanks to [Manuel Trezza](https://github.com/mtrezza)
 
-### 1.24.1
+# 1.24.1
 > __WARNING__
 >
 > Avoid using this release as it contains a [naming collission bug](https://github.com/parse-community/Parse-SDK-Android/issues/1028) that has been introduced in release `1.24.0` and fixed in release `1.24.2`. The bug causes the project compliation to fail due to duplicate class names for the `bolts-tasks` module when using the Facebook Android SDK or the Parse Android SDK Facebook module.
 
 - Resolves issue around missing bolts-tasks dependency thanks to @rogerhu (#1025)
