 ## [Unreleased]
 
+> [!NOTE]
+> This release removes many implicit features that couldn't be configured from outside.
+> It is also a part of a process of removing the features that could be easily implemented via [pre-compiled script plugins](https://docs.gradle.org/current/userguide/implementing_gradle_plugins_precompiled.html) (for example, SDK versions and tests configuration).
+> It is recommended to migrate these configurations to pre-compiled script plugins.

 ### Stable `addSharedSourceSetRoot` extension

+### Introduce `SigningConfig.fromProperties` (Experimental)
+
+It is common practice to store keystore credentials in `.properties` file.
+This extension lets you apply configurations from a property file.

 ### :warning: BREAKING CHANGES
 
 - **common:** Deprecate `redmadrobot.jvmTarget` with deprecation level `Error`.

   ```
   You can also configure [automatic toolchains downloading](https://docs.gradle.org/current/userguide/toolchains.html#sub:download_repositories).
+- **android:** Don't set default `minSdk` (it was `23`) and `targetSdk` (it was `33`).
+  It was a poor decision to set defaults for these fields as could implicitly bump an SDK version in a project.
+  If you want to use `redmadrobot.android` to align SDK versions among all modules, you should set these properties explicitly:
+  ```kotlin
+  redmadrobot {
+      android {
+          minSdk = 23
+          targetSdk = 34
+      }
+  }
+  ```
 - **common:** Disable [automatic repositories adding](https://github.com/RedMadRobot/gradle-infrastructure#automatically-added-repositories) by default.
   If you rely on this feature, consider declaring required repositories explicitly, or enable it in `gradle.properties`:
   ```properties
   redmadrobot.add.repositories=true
   ```
-- **android:** Default `targetSdk` changed from `33` to `34`
+- **android:** Don't apply [`org.gradle.android.cache-fix` plugin](https://github.com/gradle/android-cache-fix-gradle-plugin/) automatically.
+  This change allows removing android-cache-fix-gradle-plugin from the project dependencies.
+  See [the plugin documentation](https://github.com/gradle/android-cache-fix-gradle-plugin/?tab=readme-ov-file#applying-the-plugin) to learn how to apply this plugin to your project.
+- **android:** Don't apply `proguard-android-optimize.txt` rules by default.
+  If you need these rules, apply it manually:
+  ```kotlin
+  android {
+      defaultConfig {
+          proguardFile(getDefaultProguardFile("proguard-android-optimize.txt"))
+      }
+  }
+  ```
 - **android:** Do not add `LOCK_ORIENTATION` and `CRASH_REPORTS_ENABLED` variables to `BuildConfig` implicitly
+- **kotlin:** Don't set `allWarningsAsErrors` flag implicitly.
+  It was impossible to disable this feature.
+  To keep going with the old behavior, add the following code to your build script:
+  ```kotlin
+  val warningsAsErrors = findProperty("warningsAsErrors") == "true" || isRunningOnCi
+  tasks.withType<KotlinJvmCompile>().configureEach {
+      compilerOptions.allWarningsAsErrors = warningsAsErrors
+  }
+  ```
 
 ### Other Changes
 
 - **android:** Use `ANDROID_BUILD_TOOLS_VERSION` env variable for `buildToolsVersion` if the option is not configured (#132)
+- **android:** Make an extension `Project.collectProguardFiles` public
 - **android:** Add the option `redmadrobot.android.ndkVersion` to specify NDK version for all android modules
 - **android:** Remove the workaround for Explicit API enabling as the issue has been [fixed](https://youtrack.jetbrains.com/issue/KT-37652) in Kotlin 1.9
 - **android:** Remove disabling of build features `aidl`, `renderScript` and `buildConfig` as they are already disabled by default in new versions of AGP
 - **kotlin:** Deprecate accessor `kotlinCompile`.
   It is recommended to use `kotlin.compilerOptions { ... }` to configure compilation instead.
