### Step 1: Ensure Elasticsearch minimum requirements are met

_2019-02-04_

 *  **This release bumps our minimum requirements to Java 8+ or Android 5+.** Cutting off old
    devices is a serious change and we don't do it lightly! [This post][require_android_5] explains
    why we're doing this and how to upgrade.

    The OkHttp 3.12.x branch will be our long-term branch for Android 2.3+ (API level 9+) and Java
    7+. These platforms lack support for TLS 1.2 and should not be used. But because upgrading is

# Do not do this. If enabled protobuf's core internal target 
# @com_google_protobuf//python:protobuf_python will start depending on a bunch
# of cc_binary shared libraries artifacts, which will mess with how we link 
# protobuf dependencies ourselves. By default this value is false, but some 
# projects enable it, which we don't want here.

 * ### Equal URLs should be equal

 * These two URLs are semantically identical, but `java.net.URI` disagrees:
