JCenter & SDK Latest Versions

We are using the Estimote SDK(s) in our Android app. Currently we have the following setup in our project level build.gradle file:

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }

        //noinspection JcenterRepositoryObsolete
        jcenter() {
            content {
                includeModule("com.estimote", "management-sdk")
                includeModule("com.estimote", "internal-plugins-api")
                includeModule("com.estimote", "cloud-plugin")
                includeModule("com.estimote", "mgmtsdk")
                includeModule("com.estimote", "coresdk")
                includeModule("com.estimote", "sdk")
                includeModule("com.estimote", "mustard")
            }
        }
    }
}

Estimote SDK(s) are the only dependencies we have that require JCenter. We have restricted that access to only the necessary modules. As you can see we have to annotate the entry for JCenter to prevent errors. JCenter is deprecated and read-only, which means no new updates. Where are newer versions of the Estimote SDK(s) being hosted? We are currently on the following versions:

    // Estimote SDK
    implementation "com.estimote:sdk:1.0.12"
    implementation "com.estimote:mustard:0.2.1"

What are the latest? Where can we find them?
