Android – Gradle error: Minimum supported Gradle version is 3.3. Current version is 3.2

When I today update Android Studio it write: Minimum supported Gradle version is 3.3. Current version is 3.2 how can I solve this problem?

Here is my build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

and second build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.tosi.ex"
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/'] } }
}
repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.2.1'
    compile 'com.android.support:design:25.2.1'
    compile 'com.github.ksoichiro:android-observablescrollview:1.5.0'
    compile 'com.android.support:support-v4:25.2.1'
    compile 'com.android.support:mediarouter-v7:25.2.1'
    compile 'com.google.android.gms:play-services:10.2.1'
    compile 'com.android.support:cardview-v7:25.2.1'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'uk.co.chrisjenx:calligraphy:2.2.0'
    testCompile 'junit:junit:4.12'
}

gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-3.2-all.zip

When I changed properties distributionUrl to 3.3-all.zip it stuck in refreshing
